Function Description

Initialization
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.
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 is blinking green and indicates the set number of occupied stations and
circuits by means of a blinking code. If an error occurs during start-up, the I / O
LED is blinking red and indicates cyclically the corresponding error message by
up to 3 blinking sequences for the diagnostics.
