When the supply voltage is switched on, the PNOZmulti safety system copies the configur
ation from the chip card.
The LEDs “POWER”, “DIAG”, “FAULT”, “IFAULT” and “OFAULT” will light up on the base
unit.
The expansion module PNOZ m ES Profinet is configured and started automatically. The
LEDs "RUN" and "ERR" display the status of the PNOZ m ES Profinet at the PROFINET.
If the expansion module PNOZ m ES Profinet does not receive a configuration from the
base unit for a period of 30 s, the expansion module PNOZ m ES Profinet connects to the
IO controller and "RUN" status is displayed on PROFINET. The error message "No Con
nection with Base Module" is sent to the IO controller.
