Operating system

3.1.3 Operating system
Following is the configuration of the master activation and the electrical in-
stallation of the fieldbus station to start up the system.
After switching on the supply voltage, the coupler determines the I/O modules
and the present configuration.
In the event of a fault, the coupler changes to the "Stop" condition. The "I/O"
LED flashes red. After a fault free start up, the coupler changes to the "Field-
bus start" status and the "I/O" LED lights up green.
