Status displays and diagnostic messages
Status displays via LEDs
The module provides the following LEDs for status display:
PROFIBUS-DP
(not labled, beneath the cover for the address switches):
2 LEDs (left RED, right GREEN) for status monitoring of the PROFIBUS-communication.
RUN
and
ERR
:
Display of the operating state and hard- or firmware errors.

B
and
U
L
:
Monitoring of operation and load voltage.
