Operating System
After master configuration and electrical installation of the fieldbus station, the
system is operative.
The fieldbus coupler begins running up after switching on the power supply or
after a reset.
Upon initialization, the fieldbus coupler determines the connected I/O modules
and the current configuration. During this phase, the I/O LED flashes red.
After trouble-
free startup, the fieldbus coupler enters “Fieldbus start” mode and
the RUN LED flashes in green.
After bus data exchange, the I/O LED lights up green.
If an error occurs during start-up, the I/O LED flashes red and a flash code
indicates the corresponding error message.
