STEVAL-SILKT01 Industrial PLC Evaluation Kit

STMicroelectronics STEVAL-SILKT01 evaluation kits implement a PLC solution with hardware architecture that meets functional safety standards IEC61508, EN 62061, EN ISO 13849-1, and EN ISO 13849-2. It represents a reference design for factory automation use cases with a hardware platform with safety integrity level SIL3.

The evaluation kit STEVAL-SILKT01 contains a STEVAL-SILKTA01 main board and two STEVAL-SILKTB01 actuation daughter boards. The board architecture offers dual-core data processing based on STM32H743ZG for the STEVAL-SILKTA01 and STM32G431RB for the STEVAL-SILKTB01.

The STEVAL-SILKTA01 main board has three connectivity interfaces available, two of which have differential communication with RS485 and CAN physical layers, and the other has Ethernet technology to support Ethernet/IP. The accompanying STSW-SILKT01 firmware package is based on STM32Cube architecture with an application layer, a driver layer with BSP/CMSIS and HAL library, and a middleware layer.
