4.1 Operation
The virtual inputs and outputs that are to be transferred via CANopen are selected and con­
figured in the PNOZmulti Configurator. The base unit and the expansion module PNOZ m
ES CANopen are connected via a jumper. The station address and the transmission rate
are set using rotary switches. After the supply voltage is switched on or the control system
PNOZmulti 2 is reset, the expansion module PNOZ m ES CANopen is configured and star­
ted automatically.
LEDs indicate the status of the expansion module on CANopen.
The configuration is described in detail in the PNOZmulti Configurator's online help.
