The module carries a number of LEDs that are available for diagnostic
purposes on the bus and for displaying the local status. The following table
explains the different colors of the diagnostic LEDs.
Label
Color Description
PW
Yellow Signalizes applying operation voltage (Power).
ER
Red
Short flash at reboot.
On at internal error.
Blinks at initialization error.
Blinks alternately with RD at wrong configuration
of the master (project engineering error).
Blinks simultaneously with RD at wrong
parameterization.
RD
Green On at "Data exchange" if Bus cycle is faster than
PROFIBUS cycle.
Off at "Data exchange" if Bus cycle is slower than
PROFIBUS cycle.
Blinks at positive self test (READY) and successful
initialization.
Blinks alternately with ER at wrong configuration of
the master (project engineering error).
Blinks simultaneously with ER at wrong
parameterization.
DE
Yellow DE (Data exchange) indicates PROFIBUS
communication
Address selector
0 1
The address selector allows you to set the PROFIBUS address of the
PROFIBUS slave. Permissible addresses are 1 to 99. Every address must
be unique at the bus.
The slave address has to be set before turning on the bus coupler.
When you set the address 00 during operation, the diagnostic data is saved
in the Flash-ROM one time. Please take care to reset the original
PROFIBUS address afterwards, so that the correct address is used at next
start-up.
Note!
Please regard that the PROFIBUS address assigned at project engineering
and the address at the address selector have to be identical to assure an
unambiguous identification of the PROFIBUS slave.
