On top of that, millions more visit the Finnish capital every year. Its two metro lines are the veins of the city, and commuters and tourists alike rely on them to get from A to B. The number of passengers in 2019 reached 92 million people and, as the city’s population is growing, the transport system – and the safety and control technology that supports it – needs to grow as well. Rail References news-258 Fri, 23 Jul 2021 11:50:00 +0200 For the TSB passenger transport system, Max Bögl uses commercial-off-the-shelf (COTS) systems from HIMA https://https://www.hima.com/en/industries-solutions/success-stories/max-boegl-uses-commercial-off-the-shelf-cots-systems-from-hima In conceptual terms the TSB is designed for urban passenger transport over distances of one to 50 kilometres and is based on magnetic levitation train technology (or maglev: magnetic levitation, for short). In essence the TSB concept is a driverless, automated passenger transport system with an asynchronous short stator linear drive. This means that in the TSB, unlike older systems such as, e.g. the Transrapid, the active part of the system is incorporated in the vehicle and not on the track.

Due to a lack of space in the existing control rooms, standard control cabinets could not be installed. Instead, HIMA implemented a decentralized safety solution. Challenging initial situation
The plant in Dossenheim consists of several production facilities with associated technical rooms. Each of these production areas is equipped with different equipment, such as reactors, which are used to produce various active pharmaceutical ingredients. Increased safety requirements necessitated a revision of the entire safety concept of the Dossenheim plant. In addition, integration into an existing Yokogawa control system was an absolute must for the new, comprehensive safety concept. One particular challenge was the programming of the formu­lation management and the associated sequences.

Flexible Installation
Various products are manufactured in each of the reactors. For each product, a “formulation” is stored in the control system, which is defined via a sequence. Any future safety system would have to safely execute the shutdown parameters defined for each formulation.
This is where HIMA’s automation expertise came in. Individually defined sequences ensure that the correct shutdown parame­ters (according to the sequence of the respective formulation) will always react as required.

There was no room in the Dossenheim plant for a safety control system in the form of classic control cabinets being placed in a separate electrical room. Instead, a decentralized safety solution had to be devised.
In the course of the project, HIMA ended up developing the pre­configured local safety concept: a 1200 x 1600 x 300 mm box that can easily be mounted on the wall and integrated into Ex zone II. Each of the boxes contains one HIMatrix F35 03, which
is connected remotely via SafeEthernet in a ring structure – a perfect, highly flexible safety solution for Evonik.  
A total of 8 decentral ssps boxes were installed in the production and technical rooms to save space.

The extendibility of the safety systems was also an important criterion. The ability to accommodate additional I/O signals in the existing boxes at a later stage without significant effort was vital. Based on HIMatrix controllers, the decentral ssps boxes are designed for future expansion, so that up to 96 individual signals, including Ex separation, could be connected in the final configuration. This safety system, which is part of the HIMA Smart Safety Platform, offers ultimate flexibility. All safety controllers of the HIMA Smart Safety Platform (both the HIMax and HIQuad X safety controllers) are compatible with each other.

news-246 Fri, 09 Apr 2021 13:36:00 +0200 Automated Proof Testing https://https://www.hima.com/en/rss-news-sucess-stories/article/automated-proof-testing Proof testing of safety instrumented systems is not only required by safety standards such as IEC 61511, it also helps prevent unplanned plant downtime. The principle is comparable to checking the roadworthiness of a car. The tests take place at intervals that depend on the plants and devices involved and are necessary to uncover dangerous undetected faults during operation. However, such testing requires manual effort, involves numerous staff, and is time-consuming. Thanks to modern safety systems and the “digitization” of field device information, test procedures can now be automated to a large extent, which facilitates work in the field and opens up potential savings. Extending Proof Test Cycles for Safety Equipment and Saving Resources

In the process industry, IEC 61511 requires validation before commissioning and, after modifications, proof tests to be performed during operation. This involves verifying the functions and components, checking the documentation, and performing visual inspections. All these tasks are performed under tight deadlines as shutting down production during the tests has a negative impact on earnings. The range of tasks is broad and includes a wide variety of activities: Are the right devices installed with the appropriate hardware and software versions? Have the parameter settings of field devices and the safety application remained unchanged? Do all components work reliably? Are measuring points labeled and the labels legible? Are there signs of wear or leaks? Is replacement, calibration, or overhaul required?

Optimizing Test Procedures

Going forward, a properly trained employee will still have to physically inspect the facility in order to clarify some of these questions. However, it is possible to automate a significant portion of the tests and their sequence can even be digitally synchronized with manual activities. For example, the teams in the control room and in the field must coordinate with one another, and test instructions must be devised and performed in accordance with a checklist. Subsequently, the information about the status of the plant and devices must be documented. Enormous time and resource efforts are required and the need for optimization is therefore high.

The combination of device and system status information in the safety application opens up new ways of performing tests (Figure 1). Consequently, it is possible to interpret the data from field devices that is relevant for the safety application and to control test functions from the safety application. Device status can be monitored, and alarms in the event of deviations issued or the desired response initiated. Test and diagnostic functions of field devices can be triggered and evaluated based on the plant status. This has also been recognized by NAMUR. In NA 106, it describes the flexible proof testing of field devices in safety instrumented systems and lists options for automatic detection of faults in section 6.2.3.

Safety instrumented systems (SIS) are usually implemented using safety-related PLCs. The application of such programmable systems opens up the possibility of implementing automatic diagnostic mechanisms for fault detection in field devices and using them for partial testing of the safety system. The prescribed tests of these field devices can then be performed automatically in full or in part at predefined times, for example, using test procedures stored in the safety controller, and the results can be recorded in documents suitable for approval by a certification body such as TÜV. Depending on the plant status, partial tests can also be performed during operation to avoid plant shutdowns. Such an approach not only simplifies proof testing. Using diagnostic data and internal self-tests of “intelligent” sensors and actuators, it is also possible to extend the test intervals and implement preventive maintenance measures.

Safety plus Security

As the world's leading provider of safety solutions, HIMA (see company information box) has created the prerequisites for integrating of field device data and automation of test procedures. Thanks to the data integration of field devices and the matching Smart Safety Test function, proof test procedures can now be fully or partially automated within the safety system. This can be further enhanced by using HART modules for analog inputs or outputs, which provide central access to all HART information. This data can be used to monitor the settings of field devices. It detects any parameter changes performed with a hand-held device and triggers the respective alarm (Figure 2).
The integrated HART firewall in SIL 3 quality prevents unwanted changes via an AMS (Asset Management System). The HART firewall can be set to allow read-only access to field devices and block any write commands. This not only means that the devices are secure against unauthorized tampering, but has a desirable side effect: The parameter setting of the field devices via an AMS can be activated when required, e.g., during commissioning. Manual parameter setting with a hand-held device is no longer necessary, which reduces the risk of operating errors. During safe operation, the safety controller only allows read access to the field devices.

Automated Testing

Alongside the classic programming of test procedures in the safety application, Smart Safety Test can be used to automate test procedures. Certified to T2 in accordance with IEC 61508 (Figure 3), this tool is easy to use and allows users to create test plans, define fully or partially automated procedures, and document the test results.

Smart Safety Test is part of the engineering environment and enables effortless creation of test plans. When a test plan is executed, it accesses the safety controller and writes or reads values in the sequence defined in the test plan. The results are compared to the defined setpoints and documented. As a result, it is possible to set up fully and partially automated processes for the validation of safety functions, automatic revalidation in case of changes, and automatic proof test procedures.

Which Automated Tests Are Possible?

Test procedures can be defined as part of the safety application or as a test procedure to be performed manually as part of the Smart Safety Test. Tests that should be performed partially or fully automatically during operation are usually part of the safety application whereas Smart Safety Test is used for testing during downtime.

There is a wide range of test tasks that can be automated (Figure 4): In addition to the identification of field devices, monitoring of the configuration, and evaluation of the diagnostics as described above, test scenarios can also be implemented. For comparative measurements, runtime measurements, or leak tests, for example, it is also possible to specify values, control actuators, and check their feedback signals. Integrated device diagnostics, such as with Heartbeat Technology for Endress+Hauser sensors, can also be triggered and evaluated automatically. Heartbeat Technology, developed for analyzers and flow, level, pressure, temperature, and measuring devices, can detect issues such as corrosion and deposits. It generates diagnostic, verification, and monitoring data that provides information about the status of the field devices. For actuators, a partial stroke test can be used to detect faults. The partial stroke test, which can be run during operation, reveals malfunctions and reduces the probability of failure of the safety valves. For sensors, test procedures such as simulation of different measurement states or of the 4…20 mA signal are possible, including verification of the measured values via the input of the safety controller. These are just some of the available options – depending on the sensor or actuator used, further evaluations and test scenarios can be realized.

However, since such solutions not only depend on the right hardware and software, but proper planning, installation, and testing of the overall solution, HIMA also offers the appropriate support with its Safety Services. Starting with independent consulting on standards, device selection, and suitable test procedures, through the preparation, organization, and documentation of test procedures, to the performance of visual and functional tests on the safety controller, control system, and sensors and actuators.

news-242 Tue, 27 Oct 2020 10:48:00 +0100 HIMA's Safety Technology Guarantees the Availability and Productivity of New World-Scale BASF Production Plant for Acetylene at the Ludwigshafen Site https://https://www.hima.com/en/rss-news-sucess-stories/article/himas-safety-technology-guarantees-the-availability-and-productivity-of-new-world-scale-basf-produc A complete solution consisting of hardware, software and engineering protects and secures safety-critical production processes in this complex project. BASF's Ludwigshafen site now includes a new world-scale production facility with the capacity to produce 90,000 metric tons of acetylene per year. When it came to planning and implementing functional safety, BASF opted for state-of-the-art safety technology from HIMA. Around 20 production facilities at the Ludwigshafen site use acetylene as a starting material for many other products and value chains. The modern production process of the new facility uses raw materials very efficiently. Furthermore, the heat given off during production will be used to generate energy. The end-product yield is higher and by-products are used efficiently. As a chemical component, acetylene has a diverse range of applications. It is an important starting material for many everyday products, including pharmaceuticals, plastics, solvents, electronic chemicals and highly elastic textile fibers.

Non-Stop Operation
In the new acetylene facility, HIMA's controllers not only perform the classic ESD function, they also handle the complex functions involved in starting up and controlling the equipment. The SafeEthernet protocol ensures safe cross communication between controllers in SIL 3 quality. Fast response times in the event of a safety shutdown and the high operational safety (SIL 3) within safety-critical production processes contribute to the acetylene facility's high availability and productivity. Additionally, the HIMax hot swap function enhances the future-safe design of the facility as redundancy allows upgrades to be implemented during operation.

“Just-in-Time” Delivery
HIMA and BASF started their joint work on this project in 2017. After the intense planning phase, in 2018 HIMA delivered 61 BASF control room racks based on a total of six HIMax systems. To enable read out of the field devices, 103 X-HART modules were also integrated into the HIMax controllers. HIMA wired and tested (FAT) the HIMax controllers in-house and delivered the pre-assembled complete modules, including separation layer in accordance with the “just-in-time” requirements of the construction site. This ensured smooth installation and timely construction progress while relieving BASF of the effort for on-site basic wiring.
Since October 2018, two HIMA engineers have also been permanently based in Ludwigshafen to make sure that the safety solution is seamlessly integrated into the existing automation architecture and that the commissioning schedule is met.

Complete Solution from a Single Source
Despite the complexity of the system, HIMA was able to design a lean and highly reliable hardware solution. This was possible thanks to the HIMax system, which can comprise 15 base plates with 18 I/O slots in each controller and is therefore extremely modular and flexible. Additionally, HIMA was able to contribute its safety expertise and solution competence beginning with the planning phase: HIMA engineers proactively assisted in designing the hardware and programming the application-specific software, in particular for implemention of the complex burner control circuits. The resulting solution was then easy to integrate into the specified DCS system.

"We have been working successfully with HIMA at the Ludwigshafen site for many years and have found the experience with our partner's safety solutions to be excellent. It seemed logical to also rely on HIMA's technology and expertise for the new acetylene plant. The HIMA experts' service and engineering played a significant role in ensuring that the safety systems were delivered and commissioned smoothly, and that the construction progress schedule was met", said Meinrad Rämisch, Senior E&I Engineering Manager at BASF."

news-237 Mon, 03 Feb 2020 21:00:00 +0100 Remote Access: Securing the Safety Periphery https://https://www.hima.com/en/rss-news-sucess-stories/article/remote-access-securing-the-safety-periphery At the 24th Annual ARC Industry Forum in Orlando, Florida, February 3 - 6, the HIMA Group will present the upcoming roadmap and new services complementing the HIMA Smart Safety Platform (SSP). HIMA introduces a solution for remote maintenance in the industrial context, living up to the standards set by SSP, the world’s first scalable safety platform with built-in cybersecurity. As the HIMA SSP offers a future-proof solution to the process industry that is both safe and secure, the new remote maintenance solution is the perfect and logical addition: It helps to reduce operating costs and increases productivity, while the combination with SSP is protecting the plant against the growing risk of cybersecurity attacks.

“Having both safety and security in mind, many companies face a tough choice, when making a decision regarding remote maintenance”, says Dr. Alexander Horch, VP R&D and Product Management at HIMA. “On the one hand, everybody can see the potential of substantial cost advantages if remote maintenance of process systems is carried out via public networks. On the other hand, though, there are substantial security risks to be reckoned with as well. If a company hasn’t established effective protection mechanisms, it only takes one weak spot to jeopardize the entire production process. With SSP we made the ‘core’ secure and now we follow up with a complete unitary solution or remote access, which meets highest requirements regarding safety and security.”

Remote maintenance solution fulfilling highest standards for safety and security

To address the challenges all companies in the industrial context face, HIMA’s remote maintenance solution fulfils the highest standards for safety and security, without any restrictions on scalability. HIMA clients and new customers alike can easily implement a secure remote maintenance system which conforms to requirements set by the German Federal Office for Information Security (BSI). Hardware, software and support come all from one source, reducing complexity perceptibly.

Future roadmap includes data diodes

The future roadmap focuses on the secure connection of mobile workers, encrypted communication via the internet, interface control and internal network segmentation with firewalls, as well as the networking of highly critical systems and ‘data diodes‘. Data diodes are integral components of modern automation systems such as NAMUR Open Architecture (NOA) or Open Process Automation. Secure data transmission from a highly sensitive area to a less sensitive one places high demands on the components. Especially when all boundary conditions for performance, operability, economy and safety are taken into account.

news-235 Mon, 28 Oct 2019 08:52:27 +0100 Significant Partnership Deal Signed between EFACEC and HIMA https://https://www.hima.com/en/rss-news-sucess-stories/article/significant-partnership-deal-signed-between-efacec-and-hima Sweden had already submitted a plan for the digitalization of rail in 2017, and now its rail infrastructure owner is relying on COTS solutions for the modernization of level crossings. EFACEC, a market leader in the rail sector, turned to proven HIMA technology to design a new solution for level crossings and make this vision a reality. For EFACEC, this major project in Sweden involves the modernization of a significant part of the Swedish level crossings over a period that can extend over the next 25 years and include more than a thousand units. Answering to Trafikverket’s specific requirements, EFACEC’s XSafe level crossing control system will be used - XSafe is the latest version of EFACEC's automatic level crossing control system, based on HIMA's proven COTS technology, and for this particular project the HIMatrix F30 COTS controllers will be used.

"For EFACEC, this major order to modernize level crossings in Sweden is an important milestone," said Pedro Pinto, Manager of EFACEC’s Transportation Business Unit. "With the innovative concept of XSafe – using COTS technology – we were able to prevail against strong European competitors. At the same time, we have continued our successful partnership with HIMA. Our aim is to further expand our position in Scandinavia as a supplier of safety-critical systems for rail transport."

Delivering results via a strong partnership

EFACEC has been working with HIMA as safety supplier to EFACEC’s signaling and level crossing solutions for more than a decade . Recently, besides the specific contract for the level crossing project in Sweden, another contract was signed between EFACEC and HIMA concerning an overall partnership covering technological cooperation, training for EFACEC employees, detailed documentation and the necessary software tools.

Sedat Sezgün, Group Vice President Business Segment Rail at HIMA, commented: "This new partnership with EFACEC in such a major project is another important step for us as a provider of COTS solutions. COTS is already widely used as a forward-looking and competitive solution in European rail networks and, in addition to SIL4 certification in accordance with CENELEC, offers many advantages in terms of standardization and flexibility as well as great cost reduction potential".

XSafe: Setting the standard across Europe

The powerful XSafe controller is based on the SIL 4 certified HIMatrix series from HIMA. Its decentralized design with IP-based communication to individual modules has proven to be outstanding for this type of application, especially with regard to interfacing with other railway systems. This enables significant cost reductions, among other aspects in optimized cabling. Thanks to the modularity and flexibility of the HIMatrix platform, XSafe offers a highly configurable solution suitable for almost any type of level crossing.

EFACEC and HIMA have, for example, already successfully deployed XSafe level crossing systems in Portuguese and Polish rail infrastructure.

news-233 Mon, 21 Oct 2019 11:00:00 +0200 sps 2019: HIMA presents HICore 1 safety SoC https://https://www.hima.com/en/rss-news-sucess-stories/article/sps-2019-hima-presents-hicore-1-safety-soc Products to be certified according to IEC 61508 up to SIL 3 and/or ISO 13849-1 up to PL e can be developed efficiently and quickly based on the HICore 1 safety SoC and associated software package. In particular, the modular software platform – already certified by TÜV Rheinland – consisting of the operating system and middleware allows safe products to be launched within a predictable time frame. Secure communications with other devices and controllers (safety PLCs) is especially important for future functional security products. With the existing implementations of Fail Safe over EtherCAT (FSoE), HIMA ISOFAST and PROFIsafe, as well as the CIP Safety and CANopen Safety functions currently being developed, HICore 1 offers an excellent platform for this. The modular architecture of the software package allows different versions of the same product, with a variety of fieldbus connections, to be developed without undue effort and expense. Interested parties can learn more about the full range of HIMA offerings at the HIMA stand. They include consulting services, support for certification, and engineering up to turnkey production. Safety-critical systems must be functionally safe, and this safety has to be proven by certifications. In more and more cases, functional safety is not only a decisive consideration for customers, but also a considerable time and cost factor for development departments and companies. Here they face a twofold challenge: rising development costs for increasingly complex products are often multiplied by growing safety requirements. In today's world with pressure from cost cutting and tight market launch deadlines, unnecessarily high certification expense is undesirable and uneconomical. Being able to draw on precertified safety solutions thus gives companies a key advantage.

“With HICore 1, the smallest TÜV-certified safety SoC, innovative product and system manufacturers can make their solutions safe and certifiable,” says Dr. Stefan Gölz, Director Technology Embedded Solutions at HIMA. For developers, the package solution based on HICore technology results in distinctly lower effort because it dramatically simplifies and accelerates TÜV approval of their own products in line with IEC 61508 up to SIL 3 or ISO 13849-1 up to PL e. As a result, time to market can be shortened by 30 to 70 percent, depending on project size and scope.”

Users can personally choose the configuration of their HICore solution, from safety-SoC to finished boards. HIMA guides and supports the entire process, from specification through TÜV approval to production. With HICore 1, SIL 3 safety can be easily and economically integrated in many industries, even with networked applications. Numerous safety network protocols are already available, so the Industry 4.0 concept of safe and highly efficient machine-to-machine communications is also supported. Examples of typical application areas include safety-oriented controllers and safe monitoring of driverless transportation systems, drives, logistics and intralogistics, sensors, actuators, and power plants.

Off-the-Shelf” at Trako, 13th International Railway Fair, 24th – 27th September, in Gdansk, Poland. COTS controllers with CENELEC SIL 4 certification will form the central focus at Stand 26-2 in Hall D. These safety systems have been installed in countless rail projects around the world. Their open architecture allows operators, system integrators and rolling stock manufacturers to benefit from a high level of flexibility in terms of the choice of supplier, the long-term availability of components and maximum safety.

"COTS is already widely used as a forward-looking and competitive solution in European rail networks. The SIL4 certification in accordance with CENELEC, offers many advantages in terms of standardization and flexibility as well as great cost reduction potential," says Sedat Sezgün, Group Vice President Business Segment Rail at HIMA. "We are looking back at many successful rail projects operating COTS technology in middle and eastern Europe, for example in Serbia, Russia, Poland, and Hungary.

For instance, the company Signalling & Control from Serbia has used COTS components from HIMA to create its own electronic interlocking solution. This has proven effective in multiple projects for Železnice Srbije (Serbian Railways), where scalability and pre-certification were decisive. Certified COTS products provide a cost-effective and time-saving solution, which is especially important for smaller companies. In Russia, the rail company AT TRANS created an interlocking solution based on HIMA’s HIMatrix controllers, which not only maximize safety, but also optimize train scheduling. The HIMA technology is directly linked to axle counters so they can track the location of trains in real time. In addition to performing all relevant safety functions, the controllers convey valuable information to the company’s logistics man¬agement software. This enables AT TRANS to plan its trains much more efficiently.

COTS: Superior safety and profitability for rail sector

HIMA has been one of the first manufacturers to offer SIL4-standard controllers compliant with CENELEC. Today they are used by 50 partners in over 30 countries. The controllers are part of the “Smart Safety Platform” which is the first comprehensive solution in the world to combine safety and security. The hardware and software components in the platform are uniformly tailored to each other. HIMA's COTS controllers make it possible to realize safety solutions for signals, level crossings and rolling stock cost-effectively, easily and quickly. Another benefit of the platform is the extremely high level of security – a crucial factor at a time when the digitization of the rail industry is gaining pace around the world.

Irrespective of whether a controller is central or decentralized, redundant or not, the COTS components from HIMA guarantee reliable and continuous operation for safety-critical railway applications such as electronic signaling technology, level crossings, sensor-monitored door opening systems, electronically controlled slide and wheel slip protection, safety controllers, remote control, safe train movement and much more.

news-227 Wed, 14 Aug 2019 11:00:00 +0200 Smooth upgrading of process plants with the HIQuad X: New flexible safety system simplifies plant modernization https://https://www.hima.com/en/rss-news-sucess-stories/article/smooth-upgrading-of-process-plants-with-the-hiquad-x-new-flexible-safety-system-simplifies-plant-mo HIMA Paul Hildebrandt GmbH, world's leading independent provider of smart safety solutions for industrial applications, has brought a new programmable safety system onto the market. The flexible and scalable HIQuad X is a further development of the HIQuad, which has been securing over ten thousand applications worldwide for around 30 years. It fits seamlessly into HIMA’s Smart Safety Platform. The HIQuad X is not just a flexible, efficient safety system; it is also an important component in HIMA’s new, technically coherent Smart Safety Platform, which unifies all HIMA safety systems. Hardware and software are closely aligned. Plant operators thus receive a scalable solution which they can use to cover the complete safety and security requirements for small single applications right through to complex architectures of large-scale plants in line with requirements.

The Smart Safety Platform is based on the use of basic components which are identical for all HIMA product families, including operating system, engineering tool and communication via SafeEthernet. The fact that platform components can be combined freely means that virtually every customer solution can be developed and implemented. The holistic approach enables companies to use a solution from one source, thereby reducing the complexity of their plants considerably.

New performance dimensions, flexible system architecture and integrated intrinsic safety (Ex protection)

With the implementation of the proven platform technology, the HIQuad X reaches a new performance dimension. Users thus benefit from a reduced system cycle and reaction time, particularly for floating point calculations. The increased diagnostic capability, which permits quicker defect tracking during maintenance work, provides additional benefits. On the one hand the more flexible system architecture enables the timely use of redundant modules right through to complete redundancy. On the other hand retrospective adaptations to the system for application programs, hardware and communication can be undertaken - even during operation.

The HIQuad X system also enables the use of SIL3 modules with integrated intrinsic safety (Ex protection). Users no longer need a separate isolation amplifier for their intrinsically safe SIL circuits. The benefits of the diagnostics provided can therefore be utilized up to the field device without any losses. Other benefits include the simplification of planning, documentation and furnishing proof of the intrinsic safety. The fact that flawed plant outages due to defective isolation amplifiers are no longer an issue is another huge bonus. This is made possible by the redundant connection options which always permit the exchange of defective system components during operation.

The HIQuad X system can of course be connected with every basic process control system (BPCS), even on a redundant pathway. It then continues to run independently even if an error occurs in the BPCS or in the communication. The security mechanisms which are installed assist with this process. They create a virtual and also a physical separation when standard protocols are used. HIMA customers who already use HIQuad systems benefit from the upgrade to HIQuad X with short plant outages and considerably reduced costs when compared to new installations. The I/O modules including field wiring can continue to be used. This enables users to make savings in terms of investment and costs for testing and documentation.

news-225 Tue, 06 Aug 2019 11:00:00 +0200 HIMA presents solution for reliable remote maintenance compliant to the newest expert recommendations https://https://www.hima.com/en/rss-news-sucess-stories/article/hima-presents-solution-for-reliable-remote-maintenance-compliant-to-the-newest-expert-recommendation HIMA, together with their strategic partner genua GmbH, specialist in IT security, are proud to present a solution for remote maintenance in the industrial context. This remote maintenance solution fulfils the highest standards for safety and security, without any restrictions on scalability. “When it comes to the question of ‘Remote maintenance, yes or no?’, a lot of companies still face a tough choice,” says Heiko Schween, Head of Automation Security at HIMA. “On the one hand, they can see the potential of substantial cost advantages if remote maintenance of process systems is carried out via public networks. On the other hand, though, there are substantial security risks to be reckoned with as well. If a company hasn’t established effective protection mechanisms, it only takes one weak spot to jeopardize the entire production process.”

High demands on a secure remote maintenance solution

If safety and security are put at risk, this can result in financial loss due to interruptions in production. In the worst case scenario this can even lead to far-reaching damage to personnel and to the environment. All this means it is essential to weigh the benefits against the risks. The German Federal Office for Information Security (BSI), in its recommendations regarding cyber security (BSI-CS 108 | Version 2.0 | 07.2018) provides an overview of the general requirements for remote maintenance in industrial environments. 

Secure protocols and top quality Encoding

The HIMA remote maintenance solution makes use of secure protocols such as SSH, IPsec and SSL / TLS. With a symmetrical encoding process such as AES256, for example, top quality encoding comes into use as well.

In addition to the password, authentication of a user can also be established by a unique identifier word generated with a Yubikey token in combination with RSA encoding.

All from one source and fully scalable

This means that existing HIMA clients and new customers alike can easily implement a secure remote maintenance system which conforms to BSI requirements, with hardware, software, and support all from one source. Complexity is perceptibly reduced. Investment security is assured by way of optionally extendible and complete IPv6 support and ongoing product upkeep. “This means that HIMA have a complete unitary solution to offer, which meets BSI requirements regarding safety and security,” says Heiko Schween.

There are no restrictions on the secure integration of automation solutions from third-party suppliers. And that means users do not encounter any limitations due to a proprietary solution. A central management system means that HIMA remote maintenance is easily scalable for large environments, too. From the single solution, via the complete solution, and on to the incorporation of an individual critical system, all the requirements can be fulfilled, on the foundation of really high availability.

news-223 Wed, 03 Jul 2019 11:00:00 +0200 Straight to the point: Smart Safety functions for field deployment https://https://www.hima.com/en/rss-news-sucess-stories/article/straight-to-the-point-smart-safety-functions-for-field-deployment HIMA Paul Hildebrandt has developed the decentralized HIJunctionBox to expand the Smart Safety Platform concept directly into the field. Thanks to its suitability for Ex Zone 2 explosion hazard areas, the HIJunctionBox can also be used under harsh environmental conditions. Pre-configuration and modular I/O enable fast and easy integration of the HIJunctionBox into existing installations. The HIJunctionBox enables plant operators to implement decentralized control and safety solutions extremely flexibly. The uniform hardware and software design allows any necessary additional modules to be retrofitted easily and implemented locally. As a result, the system architecture of an installation can always be flexibly adapted to altered requirements. In the event of loss of communication with the central system, the robust junction box continues to operate independently in the field, contributing to higher system availability.

High flexibility

Depending on the complexity of the application, the system is based on the HIMatrix or HIMax safety controller. It can be structured as a redundant system or as a mono system. High flexibility with I/O modules and the option of using the Reload function to transfer programming settings enable quick system expansion during live operation, even in the subsequent engineering process. A wide variety of functions can be implemented through modular I/O integration, from system control and monitoring to detailed diagnostics such as HART. The HIJunctionBox is supplied pre-configured and tested. The pretested basic structure allows factory acceptance tests (FAT) and site acceptance tests (SAT) to be shortened, resulting in faster overall commissioning.

Robust design for harsh environments

The “Control in the Field” feature of the HIJunctionBox additionally enables the plant operator to perform sophisticated control tasks on site, even under demanding environmental conditions. The HIJunctionBox is designed and built to meet the requirements of IP 66/NEMA 4X protection ratings in accordance with IEC 60529 and has a lockable 316L stainless steel enclosure with a wall thickness of 2 mm. It is certified for deployment in ATEX Zone 2 explosion hazard areas and can be used over the temperature range of –20°C to +55°C.

Lower infrastructure costs and simplified Engineering

The HIJunctionBox can be deployed within the HIMA Smart Safety Platform or as an extension to existing control systems. The modular and standardized design of the HIJunctionBox offer plant operators additional benefits in cost effectiveness and installation planning. For example, the number of marshalling cabinets, cable trays and master cables from the control center to the field can be strongly reduced and a standardized concept with distributed HIJunctionBoxes at the process level can be implemented. This reduces space requirements in the central rooms, some of which have costly air conditioning, and considerably simplifies cabling – both of which contribute to lower capital expenditures and optimal operating costs. Elimination of marshalling panels between the central control room and the field signals also enables cost savings. The ability to use fiber optics for communication with existing systems further reduces capital expenditures.

“The HIJunctionBox is an important field expansion of our Smart Safety Platform,” says Dr. Alexander Horch, Vice President Research, Development & Product Management at HIMA. “Plant operators can now benefit from the advantages of our platform directly at the plant. These include lower plant complexity and compliance with security requirements. The uniform hardware and software concept reduces operating and life cycle costs, and the modular approach offers plant operators maximum flexibility and a future-proof solution."

news-216 Mon, 26 Nov 2018 13:00:37 +0100 Flexible interlocking solution with HIMA technology safeguards shunting junction in French-speaking Switzerland https://https://www.hima.com/en/rss-news-sucess-stories/article/flexible-interlocking-solution-with-hima-technology-safeguards-shunting-junction-in-french-speaking BÄR Bahnsicherung deploys an innovative CENELEC SIL4 interlocking system based on Commercial off-the-Shelf (COTS) safety controllers from HIMA on a rail line in the Canton of Jura.
Bellevue is a junction station with two sidings that have a large volume of shunting traffic and are therefore implemented with secured shunting routes. Integrating the interlocking into the existing control system and interfacing to the nearby interlockings already in place, which were implemented with the TMN 840/841 block interface widely used in Switzerland, were significant challenges during project execution.

Easy integration of all elements


A basic component of the Eurolocking solution is the use of SIL4 certified HIMax safety PLCs as main computers. Using a standardized COTS safety system enables easy integration of diverse components. For example, BÄR was able to smoothly integrate the system bus and the interfaces with the standardized HIMA systems in cooperation with Frauscher Systemtechnik. That formed the basis for uniform connection of all field components. Another advantage of easy integration is that BÄR was able to develop a compact interlocking with significant space savings.
 
Availability is especially important with interlockings. As a plug-and-play system with hot-swap functionality, the HIMax controller enables fast component replacement and system modifications during ongoing operation. The subsystems utilize the smaller HIMatrix controllers, which also fulfill extremely high safety requirements but are designed for a smaller number of I/O ports. These compact, high-performance devices are particularly suitable for use in distributed time-critical applications.

The result


System installation at the Bellevue station was completed in June 2018, with trial operation starting on September 14. Thanks to cooperation with HIMA, BÄR was able to draw on a network that provided a solid basis for new product development. Interlockings based on the same platform have already been implemented by Movares for the Dutch National Railways and for the public transport operator NÖVOG in Austria.

Using standard control technology from HIMA enabled development of an interlocking that fulfills applicable industry standards (CENELEC), offers low life cycle costs and optimal integration capability as a stand-alone solution, and is suitable for line applications. The standardized communications and programming of the HIMatrix simplify handling and integration of the controllers into an existing system. Modularity and scalability enable optimal adaptation to the needs of the application and make the interlocking solution future-proof.

“Easy integration of components from different manufacturers was especially important for us in the development of the Eurolocking electronic interlocking. Using a HIMA safety controller as an open safety system fulfilled all of our expectations in that regard,” says Beat Fehr, Managing Partner and Head of Sales at BÄR Bahnsicherung. “Thanks to the COTS solution from HIMA, we were able to develop a highly flexible, scalable and cost-effective product.”]]>

news-209 Wed, 22 Aug 2018 14:39:52 +0200 Busy rail route operating in searing temperatures keeps on moving – with AKTOR and HIMA https://https://www.hima.com/en/rss-news-sucess-stories/article/busy-rail-route-operating-in-searing-temperatures-keeps-on-moving-with-aktor-and-hima Compact commercial-off-the-shelf (COTS) solutions make signaling technology between Athens and the nearby port in Piraeus run more effectively and safely.
Essential to this project therefore was to ensure that the three level crossings along the route operate reliably and, most importantly, safely. In this southern region of Greece, the average high temperature is 35 degC. In trackside equipment cabinets they can reach 60 degC or more. Therefore, the ability for the level crossings to remain fully-functional in these extreme temperatures was another critical factor to consider.

The original barriers at each of the level crossings were hand-operated. With so many trains passing though, day and night, this was neither effective nor safe. An essential upgrade was identified and AKTOR was asked to lead the project. As an international, highly diversified company, AKTOR was keen to ensure that whatever it developed it had to be without vendor lock-in. The new level crossing in the ERMIS LX project is equipped with powerful safety controllers from HIMA. The result: Full insight of barrier status and rail/road signal control for vastly improved safety, as well as increased frequency and therefore passenger capacity.

No vendor lock-in


Together, they worked on the design of the safety technology. The goal was to develop a signaling solution that complies with the SIL4 safety level according to CENELEC and install it directly on the tracks. The solution: modern COTS safety controllers from HIMA. For this project, the HIMatrix controllers were used with extended temperature ratings.

Instead of going down the proprietary route, AKTOR turned to HIMA which gave the company the flexibility to develop a solution that is also suitable basis for future projects. By writing its own code from the ground up, a set of function blocks were created that will be used and further developed, ensuring continuous improvement.

AKTOR has developed a monitoring system called ‘ARTEMMIS’, which collects all the data from the trackside equipment and displays their status on a monitor in real-time. Furthermore, the station master is able to send commands via this system to perform certain functions – such as closing the barrier in an emergency situation.

“Many of the specialist suppliers of interlockings do not support peripheral components from other vendors,” explains Athanassios Zacharatos, Signaling Project Manager at AKTOR. “This can make it quite expensive and sometimes the system is not flexible enough to meet the desired requirements. The ERMIS LX project is the first time we had used HIMA safety controllers, which are lower-cost COTS products with no vendor lock-in. With everything taken into account, including cost-savings achieved by being able to shop around for peripheral components, we’d estimate a saving of 40%. And, because they comply with CENELEC SIL4 and have already been tested in the field in numerous and varied safety critical applications, we were confident of a robust and reliable solution.”]]>

news-205 Mon, 13 Aug 2018 13:47:10 +0200 Making Level Crossings Safe https://https://www.hima.com/en/rss-news-sucess-stories/article/making-level-crossings-safe HIMatrix safety systems from HIMA have helped ERB Technologies save money and increase safety in an advanced electronic level crossing system.
Stemming from this, ERB Technologies, a supplier and installer of technologically advanced railway signaling, trackside and communication products and systems to both South Africa and the rest of Sub-Saharan Africa, has responded. ERB has developed a new, advanced electronic level crossing system in collaboration with leading foreign companies. This system ensures safety, is cost effective, and complies with the new regulations. In particular, it meets the requirements of SANS 3000-2-2-1, the new railway standard for level crossings that was introduced in 2012 and which makes reference to European IEC standards and CENELEC.

Excellent visibility and control thanks to HIMA's Safety System


Unlike most of the existing level crossing systems which are relay based, ERB Technologies’ design uses electronics technology to provide superior visibility and control. Their solution is based on HIMA’s HIMatrix Safety System, which they found to be the market’s best-suited product, meeting all requirements. It is South Africa’s first COTS level crossing system to meet CENELEC SIL 4. A successful pilot project has been completed, based on the first level crossing system installed at BMW’s plant in Rosslyn, South Africa.

The ERB/HIMA system offers many advantages to rail operators. While being cost-effective and readily available due to its COTS status, the HIMA hardware’s SIL 4 (CENELEC) certification meets the EN 50126, 50128, and 50129 standards. This certification is backed by a proven track record in rail and other industries.

Considerable savings through fast troubleshooting and simple maintenance


Operators also enjoy great flexibility and freedom, as the HIMA system complies with open standards for easy interface with another vendors’ equipment, while avoiding vendor lock-in. The system is modular and configurable, and with an MTBF (Mean Time Between Failure) of over 100 years, it is highly reliable, helping to reduce costs throughout the operating life. Further savings are achieved as the system is easier and faster to troubleshoot, while being easy to maintain – unlike relay systems, which required extensive physical work. During operation, Sequence of Events can also be automatically recorded.

Reliability is further enhanced through ERB Technologies’ extremely sturdy, vandal-resistant, steel cabinet design, which features a double skin and forced air cooling.

news-187 Tue, 03 Jul 2018 15:00:33 +0200 HIMA-based signaling technology keeps the Luxembourg City trams on track https://https://www.hima.com/en/rss-news-sucess-stories/article/hima-based-signaling-technology-keeps-the-luxembourg-city-trams-on-track After more than a 50-year break, Luxtram reopened the Luxembourg City tram, which will eventually run from the city airport to Cloche d’Or business district. For the first phase of the project, the original signaling systems on the 3.5 km stretch between the Luxexpo conference and exhibition center and Pont Rouge were also renewed. But instead of using conventional N.S1 relays, a new concept was deployed using HIMA’s commercial-off-the-shelf (COTS) PLCs to meet the highest safety requirements and greatly increase the tram frequency.
More and more system integrators and railway operators worldwide rely on standardized, open safety systems to meet these requirements for urban transport. The experts from French rail specialist Mobility worked closely together with the German safety expert specialist HIMA on the design of the technology. By using modern COTS controllers, the resulting signaling system meets the high safety requirements.
 
One of the major benefits of using HIMA controllers is that the signaling system can be monitored centrally. Compared to conventional relays, they make Luxembourg's tram traffic not only safer but much faster. This is because their high performance enables the time intervals between two trams to be considerably shorter. According to the Luxembourg Ministry of Sustainable Development and Infrastructure, the average number of tram passengers on weekdays during the first two months of operation was some 17,000 – more than twice as many as it had originally forecast (8,400).

Another important aspect to the project was to maintain the city's architectural aesthetic. By using the compact HIMA technology, Luxtram was able to save substantial space in the track area: the new control cabinets were integrated into the architecture of the stops and transfer platforms. At the LuxExpo stop, for instance, the control cabinet is installed directly on the track. This saved the substantial costs and issues often incurred when using conventional technology which would require building of an entire technical room. This poses a major challenge for city planners and so, in densely built-up areas, are often laid underground near the tracks. “The Luxtram project is the first time we used HIMA safety controllers,” says Stéphane Berthet, Business Unit Manager Light Rail Signaling at Mobility. “We chose them because they comply with the highest safety levels and have already proven themselves in numerous safety-critical applications.”

Luxtram completed the project six months ahead of schedule during its anticipated two-year timeframe. The open, modular COTS components helped reduce lifecycle costs – they were easy to install, and in-service updates ensure they are kept in sync with the latest technology. “Thanks to the good cooperation with HIMA's safety specialists, we were able to complete the project faster than planned and implement a signaling system that‘s future-proof and offers easy handling,” confirms Berthet.

news-177 Mon, 14 May 2018 14:54:02 +0200 After more than a 50-year break: The Tram is running again – with Mobility & HIMA! https://https://www.hima.com/en/rss-news-sucess-stories/article/after-more-than-a-50-year-break-the-tram-is-running-again-with-mobility-hima Compact commercial-off-the-shelf (COTS) solutions make the signaling technology of the Luxembourg city tram fit for the future.

Modern safety technology

Experts estimate that the number of professional commuters in Luxembourg will double by 2030. The reactivation of the tram lines is a measure intended to cope with this high volume. In order for the Tram to be able to resume operations, Luxtram awarded the French rail specialist Mobility, with the target to deploy signalling system in accordance with highest safety requirements: SIL4. Instead of a system with conventional N.S1 relays, plans called for a space-saving solution with programmable logic controllers (PLCs), Mobility took the opportunity to deploy his new concept based on HIMA Safety PLC. At the same time, the plan was to also significantly increase the frequency of the trams in order to increase the number of transported passengers and to ensure the Tram‘s longevity for the future.

The experts from Mobility worked closely together with the French HIMA branch on the design of the safety technology. The goal was to develop a signaling solution that complies with the SIL4 safety level according to CENELEC and install it directly on the tracks. The solution: modern COTS safety controllers from HIMA.

Space savings

Luxtram and Mobility’s decision is in line with the trend: more and more system integrators and railway operators worldwide rely on standardized, open safety systems to meet the requirements of urban transport with the increasing volume of passengers, increasing connectivity, limited installation space and digitalization.

By using the HIMA technology, Luxtram was able to save substantial space in the track area: the new control cabinets were able to be optimally integrated into the architecture of the stops and transfer platforms. At the LuxExpo stop, the installation of HIMA safety controller solution in compact control cabinet directly on the track saved the costs and issues caused by building of an entire technical room measuring 3 x 7 meters when using old fashion technology. Large technical rooms like those used in traditional relay solutions are not only a major challenge for planners due to the lack of space in urban trams: they are also an additional cost factor when they e.g. need to be laid underground near the tracks in a densely built-up area. "The Luxtram project is the first time we used HIMA safety controllers, because they comply with CENELEC SIL4 and have already proven themselves in numerous safety-critical applications," explains Stephane BERTHET, Business Unit Manager Light Rail Signalling at Mobility. "Thanks to the good cooperation with HIMA's safety specialists, we were able to complete the project faster than planned and implement a signaling system that‘s future-proof and offers easy handling."

The technical details

PLC instead of relay
  • Three CENELEC SIL4 certified safety controllers type HIMatrix
  • Long-term availability of at least 20 years in terms of spare parts and retrofit
  • The entire tram route can be monitored centrally
  • The Luxtram project was the first tram project with HIMatrix controllers
  • More than 50 axle counters and 150 induction loops were installed on the leg

news-175 Tue, 08 May 2018 17:05:20 +0200 Increase Profitability in the LNG Industry with Effective Turbomachinery Control https://https://www.hima.com/en/rss-news-sucess-stories/article/increase-profitability-in-the-lng-industry-with-effective-turbomachinery-control Turbomachinery plays a vital role in LNG production. However, concerns remain about the safety of such machinery. Uwe Bruckhoff, TMC application manager at HIMA, looks at how to prevent potential hazards – and explores the opportunities of improved turbomachinery safety. Accidents related to turbomachinery raise concerns about safety in the LNG industry. Issues such as overspeeding can lead to injuries or, in extreme cases, fatalities. Therefore, turbomachinery operators cannot afford to be lax when it comes to their machinery. Correctly safeguarding turbomachinery actually enables operators to run facilities not only more safely, but also more cost-efficiently and to achieve higher levels of availability. 
Getting Integration Right Lays the Foundations for Safe Operation
The first step to ensuring functional safety of turbomachinery at your plant is applying relevant functional safety methodologies. General safety standards, such as IEC 61511, IEC 61508, and ISA84.00.01-2004 also help to reduce the risk of severe accidents. In this way, operators ensure higher plant availability and consequently greater profitability. Nonetheless, proper care must be taken when applying safety standards within systems. Many different components – often from several manufacturers – control a turbomachine. This creates complexity due to factors including different wiring and communication protocols, which lead to higher engineering costs. An integrated system, such as HIMax from HIMA, comes into its own in this situation. The FlexSILon TMC safety solution standardizes key aspects of a system by sharing hardware, sensors, or software code, for example. This alleviates the aforementioned issues and streamlines the system. HIMax covers these requirements for integrated, SIL 3 compliant turbomachinery control. Keep Things Simple for Consistent Safety HIMax enables easy integration of safety and non-safety critical control functions. Electronic overspeed protection is at the core of a turbine’s safety functions. HIMA has developed a module for exactly this, integrated within the HIMax system. The module operates independently and does not interact with the safety system’s CPU. Open Communication Results in Greater Flexibility As a result, operators can achieve non-stop operation of their turbines over the entire plant lifecycle. Furthermore, this eliminates the need for multiple solutions from multiple manufacturers – making management and operation significantly easier. The HIMA solution supports open communication and external connection based on manufacturer-independent standards. Consequently, operators are not restricted by vendor lock-in, and the FlexSILon TMC system can be integrated into an existing automation environment. The result: Simplified communication that is less prone to failure. Become Safer. Become More Profitable. By utilizing integrated turbomachinery control and monitoring, operators can consistently fulfill functional safety requirements and standards. At the same time, LNG production also becomes more operationally efficient. By not operating multiple disparate and hard-to-wire solutions, operators can reduce costs and complexity. When it comes to controlling safety-critical functions, the ultimate aim is “partitioned integration”. Operators can achieve this by creating the system using independent functional safety modules with specialized hardware and software where relevant.

news-174 Tue, 24 Apr 2018 09:02:00 +0200 Smart Rail Summit: “COTS Has Long Been in Operation Worldwide” https://https://www.hima.com/en/rss-news-sucess-stories/article/smart-rail-summit-cots-has-long-been-in-operation-worldwide It was the first event of its kind: At the HIMA Smart Rail Summit 2018, system integrators and OEMs discussed the challenges for the global rail industry. The bottom line? A smart partnership will determine the business success of tomorrow. “I’ve worked in signal technology since 1983”, explains Dr. Dejan Lutovac to around 100 participants at the Smart Rail Summit in Mannheim. “And I can now finally develop what I’ve always wanted to develop.” It is astonishing that a speech about commercial off-the-shelf (COTS) controllers could be as personal and moving as that of the Serbian engineer. On the other hand, this did not come as a surprise to some. Many system integrators now also share similar sentiments to Lutovac, director and owner of Signalling & Control d.o.o. For decades, they had to decide whether to work with inflexible, proprietary controllers or use outdated relay technology. “That [relay technology] was actually already obsolete when I went to university,” says Lutovac. The expertise of engineers and consultants could never be used to its full potential with rigid systems.
   
Successful COTS Projects from Russia to Australia
There is a real will to rethink and improve established models for rail safety, and this was evident at the first HIMA Smart Rail Summit in Mannheim. The participants came from all over the world, and they all brought their own stories with them. Many presented real-life projects successfully running on HIMA controllers. 
Neil Popplewell, Technical Director of Rail Control Systems Australia, explained which central challenge the attendees share: the perception of COTS technology on the market. “Customers previously thought that standard controllers had a short lifecycle or wouldn’t be able to deal with future requirements,” says Popplewell. He believes that the opposite is true and that this must now be communicated to the market – something that can only be achieved by collaborating and exchanging knowledge.    
Knowledge Exchange between Rail Experts Is a Success Factor 
HIMA realizes this too, explains Sedat Sezgün, Group Vice President of the Rail Business Segment. He believes that in recent years, COTS has emerged as a global movement in the rail segment. To benefit from this momentum, a smart partnership between HIMA, system integrators, and OEMS is now required. It’s important to “exchange ideas, share experiences, and learn from best practices,” says Sezgün.  
Sezgün clearly expressed what many present already had in mind, and a live survey involving all participants proved his point. According to the study, 64 percent would like support in accessing new markets. More than half believe synchronized marketing activities to be helpful. A total of 85 percent of people asked see clear benefits of a HIMA-organized user group for COTS. “We will now evaluate how we can apply this feedback to actual projects,” says Sezgün. 
Digitization and Standardization as Megatrends 
There were definitely enough topics for the rail experts to discuss. The attendees spoke about future trends in the sector as well. The presentation on the EULYNX project by Frits Makkinga from Movares generated significant interest. EULYNX should be a universal interface standard for the rail industry that could standardize signaling technology throughout Europe. 
However, for Wolfgang Kanovsky, CTO at RDCS Informationstechnologie GmbH, the future lies in virtual stations. Thanks to fiber optic cable deployment along the track, it will soon no longer be necessary to install safety systems where the object that has to be secured is located – at signal boxes or at a level crossing, for example.  
Whether it’s inspiration or exchanging practical experience, the Smart Rail Summit was beneficial for all participants. It’s now about converting the motivating talks into actions, just as Dejan Lutovac has done. “For a small company, it is difficult to get approval for a safety solution,” he explains. “With its SIL 4 systems, HIMA came along at the right time.”

news-172 Tue, 17 Apr 2018 15:15:08 +0200 First ever Smart Rail Summit: HIMA hosts international conference for users in the railway industry https://https://www.hima.com/en/rss-news-sucess-stories/article/first-ever-smart-rail-summit-hima-hosts-international-conference-for-users-in-the-railway-industry From April 11-12, 2018, HIMA has hosted for the first time a conference for users in the global railway industry – the Smart Rail Summit. During the invitation-only event, about 100 participants from more than 20 countries discussed the current and future challenges of rail safety technology. The main question was how open, commercial off-the-shelf (COTS) solutions can support users in the railway industry in securing decisive competitive advantages with innovative business models.
All of these factors are presently leading to a change in the railway industry, which is massively investing in the expansion and modernization of infrastructure and is driving digitization worldwide. In response to the most urgent trends, executives from HIMA presented the solutions the safety specialist offers to assist the railway industry in developing innovative and future-proof business models while being compliant with the highest CENELEC safety standard (SIL4) at the same time.

The second day was fully dedicated to applications. Leading railway companies presented use cases where COTS technology already forms the basis for future-ready, cost-effective and cyber-secure solutions. The various best practices demonstrated that compared to proprietary systems, deployment of standard safety controllers gives users unmistakable added value in terms of profitability, handling and future-proofness.

Along with the two conference days packed with a wealth of opportunities for networking and knowledge transfer, the supporting program of the Smart Rail Summit provided an informal evening event in the prestigious Eichenstolz event location near Mannheim. Furthermore, at the end of the first day guest speaker Ilja Grzeskowitz talked about change management in an entertaining manner. The goal was to prepare the attending experts for the imminent change process in the railway industry under the headline of “Changing the Game.” Using humorous anecdotes, striking practical examples and exciting insights, he showed the audience the best way to deal with minor and major changes in their everyday life.

“The interest in the Smart Rail Summit was enormous and the event has been fully booked within just a few days,” says Sedat Sezgün, Group Vice President Business Segment Rail at HIMA. "Our first-ever held user conference has shown that the trend in the railway industry is clearly heading away from proprietary safety systems and towards open standard solutions. Feedback from the users clearly indicates that with COTS and HIMA as a strong partner, the railway industry is well prepared to meet the challenges of digitization.” ]]>

news-167 Tue, 27 Mar 2018 13:04:58 +0200 ACHEMA 2018: HIMA merges safety and security on a single technology platform https://https://www.hima.com/en/rss-news-sucess-stories/article/achema-2018-hima-merges-safety-and-security-on-a-single-technology-platform At this year's ACHEMA trade fair in Frankfurt (Germany), HIMA is exhibiting their Smart Safety Platform under the motto “Discover Safecurity”. This is the world's first integrated solution that combines safety and security by uniformly tailoring hardware and software to each other. That enables operators to significantly reduce the complexity of their systems and buy only what they actually need. The platform also supports integration of existing systems, enabling lower operating costs and very high security of investment.
The uniform hardware and software basis of the Smart Safety Platform reduces the effort and expense necessary for operation and maintenance of safety systems. It also simplifies extensions and system modifications. Both localized and centralized concepts can be implemented flexibly with the platform.
An important component of the Smart Safety Platform is HIMA’s new HIQuad X safety system, which fills the gap between the high-performance HIMax and the HIMatrix, which is designed for smaller applications. All HIMA controllers are now united in the new Smart Safety Platform. They can communicate with each other over SafeEthernet, and they have a uniform operating system and the same programming environment. Plant operators receive a scalable solution that enables them to meet the complete safety and security requirements of a full range of applications, from small individual systems to the complex architectures of large plants, in a need-oriented manner.

“In the year of our 110th anniversary, our Smart Safety Platform shows that we are still driving the safety market forward with innovative solutions for the digital industrial age,” says Stefan Basenach, Group Vice President Segment Process of the HIMA Group. “Digitization creates entirely new requirements for plant operators in the chemical and petrochemical industry. They need solutions that not only protect plants and employees in the event of a disaster, but also effectively counter cyberattacks and boost the long-term profitability of plants. We have introduced this paradigm shift with the new technology platform – that is what we call ‘Smart Safety’,” says Basenach.]]>

news-163 Mon, 26 Feb 2018 14:27:07 +0100 Proactive security concepts instead of reactive defense: safety and security in industrial plants needs rethinking https://https://www.hima.com/en/rss-news-sucess-stories/article/proactive-security-concepts-instead-of-reactive-defense-safety-and-security-in-industrial-plants-ne The future of the process industry is digital, and this trend is being driven worldwide under the banners of Industry 4.0 and the Internet of Things (IoT). Digitization creates many opportunities for plant operators to enhance efficiency, increase flexibility and make their plants future-proof. However, people often overlook the fact that there is also a downside: threats to plant security arising from digitization, especially as a result of rapidly growing and increasingly sophisticated cyber criminality. This article explains why the process industry needs to switch from passive to active defense mode for cybersecurity and what it must do to ensure plant security in the digital era.
According to present knowledge, the attacker benefited from a significant factor: at the time of the cyberattack the SIS had been put in programming mode by a key switch. In an orderly configuration with the controller in run mode, where program changes are not possible, the attackers would have faced a much more difficult challenge. No other attacks on the same type of SIS are currently known.

The concept of safety is changing
The incident should serve as a wake-up call to heighten awareness of cybersecurity in the industry. Although only a particular system was attacked, the incident marks a turning point for plant security. In the future the focus must be on the interaction of safety and security. The SIS in the above example differs significantly from HIMA safety systems with regard to design philosophy and technology, so it is unlikely that the HIMA systems are also susceptible to the same cyberattack. However, it is clear that no SIS manufacturer can now or in the future promise a solution that is absolutely and always safe with regard to all eventualities and risks.

That is primarily because work processes and organizational deficiencies are still by far the most common targets for successful cyberattacks. For example, system interfaces that remain open during normal operation and can be used to alter program code give attackers a potential access point. As a consequence of this cyberattack, plant operators are strongly advised to not rely solely on cybersecure components, but instead to define an integral security concept for their own systems and consistently implement it in cooperation with manufacturers.

Safety-oriented automation solutions in industrial plants must now encompass more than just safe emergency shutdown (ESD); they must also provide effective protection against cyberattacks. This leads to a paradigm shift: Previously, automated systems only had to be designed for safety and then simply checked periodically to verify the initially defined risk reduction. In the future, safety solutions must be regularly adjusted and extended in the interest of security. This paradigm shift affects providers and operators of components for safety instrumented systems in equal measure. This totally alters the perception of safety solutions. A core aspect of modern safety solutions must be the ability to fend off cyberattacks in order to avoid costly shutdowns. This makes SIS an even more significant factor for plant profitability.

Standards compliance and level separation as a basis

A welcome trend is that companies in the process industry are increasingly recognizing the importance of safety and security standards for the safety and economic viability of their plants. However, there are still companies that are not using fully standards-compliant SIS. That means they run a significantly higher risk of lost production and harm to people and the environment. To achieve maximum safety and security, it is especially important for plant operators to implement the requirement of the standards for functional safety and automation security (IEC 61511 and IEC 62443) for physical separation between safety instrumented systems (SIS) and process control systems (BPCS).

Standards compliance is a key aspect of defense against cyberattacks. According to IEC 61511, safety instrumented systems and process control systems can only be regarded as independent safety levels if they are based on different platforms, development bases and philosophies. In concrete terms, this means that the system architecture must fundamentally be designed to prevent the simultaneous use of components of the process control system level and the safety level without a detailed safety analysis. Without clear separation, patches implemented in the process control system could, for example, influence functions of the integrated safety system. That can have fatal consequences. An equally problematic situation arises when a successful cyberattack on the process control system via the office PC of an employee leads to compromising the integrated safety system, with the result that functional safety and basic cybersecurity are also compromised. As can be seen from many of the above-mentioned examples of successful cyberattacks, the link between office IT and the production system always represents an extreme weakness. An attack on an integrated SIS/BPCS system is thus considerably easier than an attack on a stand-alone SIS.

There is a lot at stake in the event of a successful cyberattack. In the worst case it can impair plant safety, with incalculable consequences for the health of employees, the material assets of the company, and the environment. Cybersecurity insurance policies, which enable companies to at least partially protect themselves against financial losses from cyberattacks, are starting to emerge. However, it is questionable whether the plant operator’s insurance coverage would be fully effective in the absence of compliance with applicable standards or if blatant security deficiencies can be proven. Cybersecurity insurance demands clear risk assessments in plants, based on applicable standards, as otherwise insurance is not possible or not financially viable. Plant operation is only reliable when plant operators systematically implement cybersecurity measures, such as separation of protection levels, in addition to functional safety.

Proactive cybersecurity is necessary
Rapidly growing and increasingly professional cyber criminality compels both manufacturers of safety solutions and their users in the process industry to pursue proactive cybersecurity policies and establish integral safety concepts. As part of risk assessment, plant operators must weigh the financial expenditures for effective safety and security concepts against the costs of potential shutdowns, which can easily run into the millions. The money invested in cybersecurity, usually only a fraction of the cost of a shutdown, is not wasted – instead, it safeguards the productivity of the entire plant.

As a user, you can opt for the best possible defense by using safety instrumented systems with the fewest possible vulnerabilities. For example, a dedicated operating system specifically developed for safety-oriented applications runs on HIMA’s autonomous SIS controllers. It includes all functions of a safety PLC and omits all other unnecessary functions. There are no software components from third-party software packages and no built-in back doors. That renders typical attacks on IT systems ineffective. The operating systems of the controllers are tested for resistance to cyberattacks during the software development process. That is also ensured by security certification of the development process and by the development processes necessary for functional safety, such as the two-person principle.

However, for plant operators it is not enough to rely on standards-compliant hardware and software. Cybersecurity is a never-ending task, and it must be developed jointly by plant operators and safety specialists in the conceptual design of new plants or prior to update measures. The minimum requirement for existing plants is an exact analysis of potential cybersecurity weaknesses. Along with technical measures, users must also implement organizational measures, because no existing technology can provide complete protection against new forms of attack. Consequently, there is a strong need for periodic checking of internal networks and communications systems, for example by penetration tests carried out by independent parties.

In other industries it is now common practice to allocate fixed budget amounts for recurrent safety and security audits. In these audits, external specialists conduct threat tests to thoroughly examine internal cybersecurity measures, with the objective of identifying and eliminating weaknesses. This amounts to proactively employing hackers to find potential vulnerabilities that could be exploited by other hackers.
The results of these tests should be used to boost safety measures in the entire industry to a uniform and effective level. Associations and the German Federal Office for Information Security (BSI) can assist in this. The latter has already published helpful documents on the subject of cybersecurity in industrial control systems from the perspective of manufacturers and plant operators.

Good safety technology is not enough
The human factor is the most frequent source of cyber risks. That includes not only targeted cyberattacks aimed at disrupting production processes or stealing industrial secrets, but also disruptions that can arise from inattention. For safety-oriented systems, the usual cybersecurity rules are even more important because the SIS represents the last line of defense against a potential catastrophe. Protection against human penetration, whether intentional or unintentional, is therefore especially important. Consequently, a comprehensive security concept includes aspects such as specific access protection, physical safeguarding, or checking the plausibility of changes. Here technology can and must form the basis for taking the pressure off people.

It is also important to constantly be aware of possible means of manipulation and take them into account. In this regard, safety-critical applications are fundamentally different from other industrial PLC or office applications. Considerable expertise is necessary to ensure security in safety applications. This is a major challenge, especially for relatively small enterprises. Consequently, maintaining and constantly refining security often poses a nearly insurmountable hurdle for plant operators. It is therefore advisable – as with the previously mentioned threat tests – to draw on the services of experienced safety and security experts in order to jointly develop and implement effective concepts. Currently one of the major threats is “spear phishing” – the targeted spying out of access data for protected systems. Once employee passwords become known, launching a cyberattack is child's play. Nevertheless, plant operators should never regard their employees as the weakest link in the cybersecurity chain. Instead, they should engage all employees and encourage them to become familiar with the issue of IT security and be part of an effective proactive cybersecurity strategy.

Loss or damage that arises from the action of an employee should be considered a system issue. Such loss or damage should demonstrate the necessity to fill knowledge gaps and familiarize employees with threat scenarios, such as known social engineering strategies. Extensive programs for security training and increasing employee awareness are thus an essential component of a proactive safety concept.

news-161 Fri, 09 Feb 2018 10:34:48 +0100 Holistic Approach for a secure last line of defense https://https://www.hima.com/en/rss-news-sucess-stories/article/holistic-approach-for-a-secure-last-line-of-defense At the ARC Industry Forum which was held in Orlando, Florida, from February 12 – 15, HIMA presented its comprehensive functional safety concept which offers maximum security by expanding the scope from the safety instrumented sycstem to its security-relevant environment.
In late 2017 a safety controller deployed in a Middle East process facility was successfully hacked. The safety instrumented system (SIS) was compromised and initiated a plant shutdown. While no damage or injuries occurred, the incident should serve as a wake-up call to heighten awareness of cybersecurity in the industry as it was the first publicly-known successful attack on a safety instrumented system – which is the last line of defense in any process plant. Furthermore, critical hardware vulnerabilities affecting most modern processors have recently been identified. Attack modes such as Meltdown and Spectre exploited these in order to steal data from computers all around the world.

“In both of the above-mentioned cases, HIMA safety controllers were not affected. But we take these incidents very seriously and work hard to always be one step ahead,” Dr. Alexander Horch, Vice President Research, Development & Product Management at HIMA comments: “It is important to note that there is no such thing as 100% guaranteed safety or security. But by choosing the HIMA holistic functional safety approach which protects the core SIS as well as its environment, plant operators get the maximum level of safety and security possible.”

The purpose of modern functional safety solutions is to reduce safety and security risks to a minimum. Therefore, a holistic approach is needed which not only includes the core SIS (final control elements, logic solver incl. I/O module and sensors), but also its environment like the engineering station, asset management tools (AMS) and handhelds as well as field entry panels and HMIs. By complementing the SIS with the “HIMA Security Environment for Functional Safety,” this approach takes all important security-relevant aspects of industrial control systems (ICS) into account. These include the five following areas: Controller hardware and firmware, engineering toolkit, PC infrastructure, communication infrastructure and lifecycle management.

In terms of firmware, a dedicated operating system specifically developed for safety-critical applications runs on HIMA safety controllers. The HIMA firmware, which is 100% HIMA software, provides an extremely low software error rate and has no backdoors implemented. It is impossible to access the program code during operation as application programs run within a container and no other parts of the CPU firmware can be accessed. On the hardware side, unused Ethernet ports can be disabled and/or locked physically. Thanks to the total separation of SIS and basic process control functions and systems (BPCS) according to the requirements of the standards for functional safety (IEC 61511) and automation security (IEC 62443), no common cause failures can occur.

When it comes to the engineering, HIMA works with its own, single-purpose engineering tool SILworX, again 100% HIMA software. This solution offers various security features such as two-factor authentication for project and controller data, a well-defined user management including security admin role as well as functional blocks with password protection (locking/read-only), just to name a few. By monitoring the application program via system variables, SILworX is even able to detect changes and to issue an alarm in case unauthorized changes are made.
 
Also, the communication infrastructure has to be secured. The HIMA security environment relies on the proprietary protocol for controller communication SafeEthernet, and the communication stack is Achilles certified by Wurldtech. Separated protection layers between CPU and COM modules lead to an absence of feedback. Networks are clearly separated via firewalls and demilitarized zones, and the controller is tap-proofed to prevent ARP spoofing.

For an effective cyber-defense, the PC infrastructure should be set up with a secure BIOS management, reduced access rights and with only the required Windows services activated. Office laptops should not be used as engineering stations. The engineering station should be kept completely separate. The PCs should feature an intelligent password management system and work with a minimal set of application programs only.

Last but not least, the lifecycle management has to take security into account, too. HIMA safety systems have received various security certifications such as Achilles, ISASecure, EDSA and TUV. The ISO 27001 certification for HIMA’s information security management systems (ISMS) is ongoing. HIMA also carries out penetration tests together with customers, service providers and universities. Development takes place in a dedicated network, and access to source codes is strictly restricted and supervised. In standardization organizations like IEC and OpenGroup, HIMA experts are proactively driving safety and security standardization forward.

“Security is an integral part of HIMA services and engineering. In addition to cyber-secure hardware and software, we provide security awareness training, basic security checks of HIMA safety systems, product security training and security lifecycle services,” explains Dr. Horch. ]]>

news-154 Thu, 25 Jan 2018 11:25:23 +0100 HIMA Security Advisory TRISIS/TRITON https://https://www.hima.com/en/rss-news-sucess-stories/article/hima-security-advisory-trisistriton At the end of 2017, the world's first successful hacker attack on a safety instrumented system (SIS) was discovered. Malware in a programming station (PC) modified older Triconex safety instrumented systems manufactured by Schneider Electric during ongoing operation. To do this, the programming station was manipulated in such a way that the usual programming function was used to exchange a user program fragment in the Triconex SIS. This modification put the SIS into a safe state. We suspect that the aim of the attack was more than to simply stop the SIS. Rather, it can be assumed that this was supposed to result in a crash. This malware is known as "TRISIS" or "TRITON" (hereafter referred to as "TRISIS"). Are HIMA products affected by TRISIS?
TRISIS has been very deliberately developed for a specific purpose. An analysis of the software has revealed that TRISIS specifically targets Triconex 3008 processors. Not even other Triconex customers are likely to be affected, let alone customers using SIS from other manufacturers. The analysis suggests that modifying the attack to infiltrate other SIS would be the same as redesigning the malware.

How can I tell if my HIMA controller has changed?
During the attack, code parts were selected in ongoing operation and were then modified and rewritten in the SIS. Since no code can be selected from the SIS in HIMA systems, the complete user program would have to be known, modified and reloaded into the SIS for a similar attack to occur. In the process, the checksum of the user program would change. Since this checksum for safety-related acceptance must be known and documented, it is easy to check for changes.

Is there a way around the read-only mode?

This would require there to be a so-called backdoor, for example some kind of "hidden developer access". A backdoor is not available for HIMA products. Access to HIMA systems during ongoing operation is only possible with the correct password, the correct port and authorized write access.

What support can HIMA offer?
HIMA documents all security-relevant settings and operating conditions in a cybersecurity manual. For this purpose, HIMA offers security training courses for the HIMA product range. In addition, HIMA offers a "Smart Safety Security Check" service, where safety installation is individually tested to ensure correct parameterization and is then optimized, if necessary. Furthermore, HIMA carries out security assessments on behalf of its customers.

How can HIMA ensure that HIMA systems cannot be compromised in the future?

HIMA has always been committed to high-quality developments because of its focus on safety. We always have these developments certified by an independent third party. In 2017, HIMA also obtained a cybersecurity certification for the HIMax system. At the same time, the existing processes for security were certified as well. These processes also ensure the best possible protection from risk of cyberattacks in the future.

How can you reduce the risk of malware spreading?
We recommend that you divide systems into various zones and to control their transitions (conduits) in order to deny unauthorized persons access. This affects both physical access and logical access via networks. The TRISIS attack clearly shows that safety systems, as the final layer of protection for functional safety, should be built separately from all other systems. Only in this way can the above-mentioned dedicated, controllable transitions (conduits) be created. This concept, where there are different levels of protection, is known as "Defense in Depth".

What can the industry learn from this attack?
Security must be taken more seriously in a safety environment. That does not mean you should panic. Rather, this circumstance proves that systematically using the technical and organizational possibilities that are currently available would have prevented this attack. This was not an attack on Triconex, but a wake-up call to the entire automation industry.]]>
