LED’s (Operation Status and Messages)
The LED’s located on the top side, a green LED (Bus Run) and a red LED (Bus Fail), serve for monitoring of op-
erating status. For setting the address are two rotary coding switches located on the top next to the LED’s
BUS RUN
GREEN
ON
= Ready
OFF
= Supply voltage not provided
Flashes cyclic
= Slave has no cyclic data exchange with PROFIBUS-DP-MASTER
Flashes irregular
= start: Missing or faulty configuration
Runtime: Host watchdog- time error
BUS FAIL
RED
ON
= unrecoverable Converter – Fault
OFF
= no error / bus in cycle
Flashing
= Converter not addressed by the master

Address Adjustment
The address adjustment is carried out with the coding switches on top of the housing. The higher decade with
the coding switch MSD and the low decade with the coding switch LSD.
