In collaboration with CENTRALP, a company specialized in the design and production of embedded electronics, CLEARSY offers a SIL2 monitor in two versions:
-
SIL2 programmable platform version: It is a generic SIL2 platform including a basic SIL2 software. The customer can thus develop his own SIL2 application (HMI). He can also subcontract to CLEARSY the realization or the integration of this application
-
in ETCS baseline 3 version in its latest version (UNISIG Subset 091 3.6.0, ERA specification v 3.6.0, SUBSET 026 v 3.6.0 chapter 4.7, SUBSET 118 v 1.4.0)
The Generic SIL2 platform (application free) provides SIL2 garantees:
-
Safety (SIL2) is managed by the low layer SW
-
Configuration tool to manage the SIL2 constraints (parameter file to be fill)
-
Functional Application: delegate SIL2 aspects to a Supervision Module already certified
-
Application must be designed to respect exported constraints (detailed in the certificate)
-
No mandatory library, you are free to develop your application
The Baseline 3.6.0 ETCS DMI provides SIL2 guarantees against:
-
Corruption of the applicative program
-
Memory corruption
-
Clock drift
-
Corruption by a Linux kernel fault
-
Wrong information display
-
Unwanted touch screen inputs
The guarantees obtained by the certificate are as follows:
-
the display of icons and text messages are correct
-
the display of complex graphical objects 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.
All you need to run your factory !
