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 Profibus is configured and started automatically. The
"ONLINE" and "OFFLINE" LEDs indicate the status of the PNOZ m ES Profibus on
PROFIBUS-DP.
If the expansion module PNOZ m ES Profibus does not receive a configuration from the
base unit for a period of 30 s, the expansion module PNOZ m ES Profibus connects to
PROFIBUS-DP and the "ONLINE" status is displayed on the PROFIBUS-DP. The error
message "No Connection with Base Module" is sent to the Master.
