Operating System
After master configuration and electrical installation of the fieldbus station, the
system is operative.
The coupler begins running up after switching on the power supply or after a
reset.
Upon initialization, the fieldbus coupler determines the I/O modules and
configuration. The 'I/O' LED flashes red. After a trouble-free start-up, the coupler
enters “Fieldbus start” mode and the 'I/O' LED lights up green.
In the event of a failure, the 'I/O' LED will blink continuously. Detailed error
messages are indicated by blinking codes; an error is indicated cyclically by up to
3 blinking sequences.
