Description

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.

Features

  • Designed to meet IEC61508-2, EN 62061, EN ISO 13849-1, EN ISO 13849-2 for a SIL3/PLe achievement
  • Dual core architecture based on STM32H743ZG and STM32G431RB
  • Dual digital outputs IPS1025H, IPS4260L
  • Dual digital inputs CLT03-1SC3
  • Full diagnostic coverage >90%
  • Galvanic isolation for data transmission, and digital I/O signals using STISO621
  • Redundancy on board, at hardware level and data processing
  • Real time communication supporting Ethernet technology for Ethernet/IP, and differential serial communication for RS485 and CAN
  • Overload and overtemperature protections, integrated on board at device level

Typical applications

  • Industrial PLC SIL3
