Abstract
A control system controls safety-critical and non-safety-critical processes and/or system components. The system includes a first control unit for controlling the non-safety-critical process and/or the non-safety-critical system components, at least one input/output unit connected to the first control unit, a communication coupler, which is connected to the first control unit via an internal coupler bus, and a second control unit for controlling the safety-critical process and/or the safety-critical system components. For providing safety-related functions, the second control unit includes a first dual-port RAM and at least two processors, only one of which is connected to the first dual-port RAM. The second control unit communicates with the first control unit via the first dual-port RAM and the internal coupler bus, and the first control unit transmits data from the second control unit to the communication coupler via the internal coupler bus and a second dual-port RAM integrated into the communication coupler.
