The STEVAL-SILKT01 is an evaluation kit designed to implement a PLC solution with hardware architecture designed to meet the requirements coming from functional safety standards IEC61508, EN 62061, EN ISO 13849-1, EN ISO 13849-2, to enable the use as a reference design for factory automation use cases having a hardware platform with safety integrity level SIL3.

The evaluation kit STEVAL-SILKT01 contains one mother board STEVAL-SILKTA01 (main board) and two daughter boards STEVAL-SILKTB01 (actuation board).

The board architecture offers a dual-core data processing based on STM32H743ZG for the STEVAL-SILKTA01 and on STM32G431RB for the STEVAL-SILKTB01.

On the main board (STEVAL-SILKTA01) are available three connectivity interfaces, two of them with differential communication working on RS485 and CAN physical layer, the other one with Ethernet technology to support the Ethernet/IP.

The hardware is coming with the firmware package STSW-SILKT01 based on the STM32Cube architecture and consisting of: application layer, drivers layer with BSP/CMSIS and HAL library, middleware layer.
