4 Function description
4.1 Functions
The expansion module operates as a signal module with non-safety-related outputs.
The function of the outputs on the safety system depends on the safety circuit created us-
ing the PNOZmulti Configurator. A chip card is used to download the safety circuit to the
base unit. The base unit has 2 microcontrollers that monitor each other. They evaluate the
input circuits on the base unit and expansion modules and switch the outputs on the base
unit and expansion modules accordingly.
The online help on the PNOZmulti Configurator contains descriptions of the operating
modes and all the functions of the PNOZmulti safety system, plus connection examples.
