Abstract
A modular safety switching system (10) with at least one output module (14) and a central control unit (28), which is connected to all output modules (14) via a bus (22). The output module (14) receives input data of at least one sensor (16) or switch (16a) and has at least one output (14b) for an actuator. The central control unit (28) is designed to receive at least a portion of the input data which is evaluated for the transferring of the output data to the output (14b). The output module (14) has its own, dedicated output module control unit (20), which evaluates the input data in collaboration with the central control unit for the purpose of transferring the output data to the output (14b). A suitable method is also disclosed.
