Artesyn to Showcase New SIL4 COTS Fail-Safe System for Train Control and Rail Signaling at Railway Interchange
Innovative ControlSafe™ Platform enables rail application developers to accelerate time-to-market
Tempe, Ariz. [29 September, 2015] - At the Railway Interchange 2015 exhibition, Artesyn Embedded Technologies will showcase its ControlSafe™ Platform, one of the first embedded computing systems to use commercial off-the-shelf (COTS) components to create a fail-safe and fault-tolerant computing platform designed to be SIL4 certified for a wide range of train control and rail signaling applications. The ControlSafe Platform enables rail application developers and system integrators to substantially accelerate time-to-market without being deterred by the potentially high costs and risks associated with the stringent SIL4 system development and certification process.
Designed to deliver best-in-class system availability as high as six nines (99.9999%)1, Artesyn’s ControlSafe Platform is designed to meet all the functional safety, reliability and availability requirements mandated by rail standards and specifications. Reliability, availability, maintainability and safety (RAMS) processes are designed to be certified to EN50126, all safety-related software to EN50128, and hardware to EN50129. This makes Artesyn’s ControlSafe Platform ideal for deployment in safety application environments to protect investment in rail infrastructure. It uses a data lock-step architecture that supports high performance modern processors, and is modular, scalable and designed to seamlessly accommodate additional I/O interfaces as well as upgraded processors that will be required throughout the product life cycle.
Visitors to the Railway Interchange event (October 4-7) in at the Minneapolis Convention Center will be able to see a demonstration of the ControlSafe Platform in booth 1153. Visitors can arrange a private meeting with Artesyn’s rail experts and a demonstration using the online appointment form.
Shlomo Pri-Tal, vice president ControlSafe Platforms, Artesyn Embedded Technologies, said: “Artesyn’s new ControlSafe Platform leverages 30 years of expertise in developing highly reliable and available embedded computer systems based on open standards. With this new launch, we are providing rail industry customers with an unmatched, highly reliable platform with 15 years of planned product life and 25 years of extended support and service. ControlSafe will help to improve our customers’ competitiveness by allowing them to focus their development efforts on differentiating end applications.”
The ControlSafe Platform consists of two redundant ControlSafe Computers (CSCs), each of which delivers fail-safe operation. They are linked by a Safety Relay Box (SRB) that monitors the health of the two CSCs, designates one as active and the other as standby, and controls fail-over operation between the two CSCs to deliver a fail-safe, fault-tolerant computer system. At the core of each CSC are two identical CPU boards that run in data lock-step mode and implement a two-out-of-two (2oo2) voting mechanism. Proprietary extensions to Wind River’s VxWorks 653 operating system assure loose synchronization of the two CPUs.
The Artesyn ControlSafe Platform includes I/O modules that provide interface to a range of communication protocols such as CAN, Ethernet, Ethernet Ring, and UART, with additional communication interfaces planned for future releases. All I/O modules have a common architecture based on the same Freescale CPU core and the same Wind River VxWorks 653 operating system, simplifying the software development environment, delivering high performance, energy-efficient processing, and supporting the extended life required by rail equipment. All I/O modules are accessed over Ethernet allowing a seamless distributed architecture where additional expansion can be contained in a remote chassis. All modules support remote on-line software and firmware upgrade without risk of rendering a system inoperable.
