l Set the device address for the module with the coding switch.
Allowed device addresses are 1 ... 125.
Every device address must only be assigned once on the bus.
Changes to the device address are only adopted when the supply voltage
is switched on again.
LED Status Meaning
PW (green) on Module supply voltage on
ER (red) on · Incorrect data transmission on the backplane bus.
· Internal fault
· Lights up for approx. 1 second when the module is restarted
RD (green) See table below
DE (green) on Error−free communication with PROFIBUS−DP
PW (green) ER (red) RD (green) DE (green) Meaning
on on off off Self−test and initialisation in progress
on off blinking off Self−test and initialisation was successful
on blinking off off Initialisation error
on blinking blinking off
· "ER" and "RD" blink asynchronously:
Configuration faulty
· "ER" and "RD" blink synchronously:
Parameter settings faulty

The backplane bus cycle is quicker than the
PROFIBUS cycle
on off off on
The backplane bus cycle is slower than the
PROFIBUS cycle
