CLEARSY, specialist of safety critical systems, adds a new success by announcing its latest certification: the SIL2 certification of a display screen, the K-Vision console.
CLEARSY developed the security software and the application. The architecture of the system was jointly done with CENTRALP, CLEARSY’s partner, which oversaw the hardware part.
The guarantees obtained by this certificate are as follows:
- the display of icons and text messages are correct
- the display of complex graphical objects (speedometer and brake level indicators for example) is also correct
- the operator’s interactions (human-machine interactions – HMI) with the touchscreen console are secure
These measures reduce the risk that the operator will not see or misinterpret the messages on the screen, and that the commands will not be considered.
In addition, the integrator can add a non-secure application part, or integrate a dedicated security application based on the already certified basic principles of the console.
Certified by CERTIFER, the SIL2 level is a safety indicator required by the ERTMS/ETCS standards for embedded DMI (Display Machine Interface) in trains.
TALGO, a major Spanish manufacturer, has recently trusted the K-Vision SIL2 product from the CLEARSY/CENTRALP partnership; it will equip the Deutsche-Bahn’s trains, a German operator known for the reliability of its systems.
