Function description
Functions
The expansion module provides additional inputs and additional relay outputs.
The function of the inputs and outputs on the control system depends on the safety circuit
created using the PNOZmulti Configurator. A chip card is used to download the safety cir-
cuit 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 control system, plus connection examples.
System reaction time
Calculation of the maximum reaction time between an input switching off and a linked out-
put in the system switching off is described in the document "PNOZmulti System
Expansion [
