Failsafe automationsystem with standard-CPU and method for a failsafe automationsystem

摘要

The system has one or more standard CPU units (CPU) for processing safety functions, one or more fail-safe peripheral units (FSM) for fail-safe entry to and output from the process and one or more communications channels, i.e. communications media and if appropriate communications units, for communications between CPUs and fail-safe peripherals. An Independent claim is also included for a method of guaranteeing a fail-safe automation system.
