Product overview

Description

The STSW-SILPLC is a firmware package (not included in the TÜV Italia (TÜV SUD Group) assessment) that implements the basic functions to meet the standard requirements for a SIL2 application.

The API supports the output driving in operating mode as well as the diagnostic and the out safe state condition in case a fault event occurs, as required by the IEC61508, to guarantee the SIL2 level.

The firmware also implements undervoltage/overvoltage detection, IPS supply voltage interruption, and output disablement in case of a fault with protection activation.

Three different communication channels manage all the commands and diagnostic: the Ethernet real-time that supports the EtherCAT slave stack protocol, the RS485 with a customized serial communication, and the VCOM that uses the ST-LINK programmer (suggested for debug).

The application firmware supports the usage of the self-test library included in the X-CUBE-STL package certified by TÜV Rheinland. To access the full X-CUBE-STL package, contact your ST representative and sign an NDA.
