Abstract

A modular safety switching device is set up such that various signaling devices in a set of possible connectable signaling devices can be connected. In this case, a typical combination of inputs and outputs that are used is provided for each signaling device. The nature of the connection of the signaling device is unique for each signaling device within the set, by which the safety switching device can identify during startup, on the basis of the electrical connections that are made, which type of signaling device is connected and what function is required for identical signaling devices. The safety switching device automatically changes itself to the required operating mode in accordance with this association.
