Abstract :
Safety PLCs (Programmable Logic Controller) are one of the appropriate tools for implementation of safety-related control system (SRCS). Their modular construction allows implementation not only control systems of defined safety integrity level (SIL), but even redundant control systems with defined availability. The contribution considers influence of redundant architectures on safety integrity of SRCS with safety PLC.
