Operating System - WAGO LONWORKS 750-319 Manual

3.1.4 Operating system

Following is the configuration of the master activation and the electrical in-
stallation of the fieldbus station.
After switching on the supply voltage, the coupler performs a self test of all
functions of its devices, the I/O module and the fieldbus interface. Following
this the I/O modules and the present configuration is determined, whereby an
external not visible list is generated.
In the event of a fault the coupler changes to the "Stop" condition. The "I/O"
LED flashes red. After clearing the fault and cycling power, the coupler
changes to the "Fieldbus start" status and the "I/O" LED lights up green.
