摘要：The invention relates to a control system for controlling safety-critical and non-safety-critical processes and/or system components, which has preferably a modulardesign, comprising at least a first control unit (1) provided for the control of the non-safety-critical process and/or the non-safety-critical system components, at least oneinput/output unit (11), (21), which is connected to the first control unit (1) via an internalinput/output bus (B2), and at least one communication coupler (5), (6), which is connectedto the first control unit (1) via an internal coupler bus (B1) and/or can be connected toadditional remote units (7), (8) via a field bus (FB). In the control system according to theinvention, at least a second control unit (2) for controlling the safety-critical processand/or the safety-critical system components is provided. In order to provide the safety-related functions, the second control unit (2) comprises at least two processors (22a),(22b) and a first dual-port RAM (DPR1), wherein only one of the two processors (22a),(22b) is connected to the first dual-port RAM (DPR1), and the second control unit (2)
communicates with the first control unit (1) via the first dual-port RAM (DPR1) and theinternal coupler bus (B1), and the first control unit (1) transmits the data from the secondcontrol unit (2) to the communication coupler (5) via the internal coupler bus (B1) and anadditional dual-port RAM (DPR2) integrated into the communication coupler (5).
