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 fieldbus module PNOZ m ES EtherNet/IP is configured and started automatically. The
LEDs "MS", "NS", "L/A1" and "L/A2" indicate the status of the PNOZ m ES EtherNet/IP on
the EtherNet/IP.
