● DP slave installed
● PROFIBUS address set on the DP slave
● Bus connector or FOC is connected
● Only for DP interface RS 485:
● Only for DP interface FOC:
● DP slave configured (refer to the online help / manual on configuration software)
● Supply voltage for DP master switched on (refer to the DP master manual)
● Configuration loaded into the DP master (refer to the online help / manual on
● DP master switched to RUN (refer to the DP master manual)
Commissioning the DP slave

If the DP slave is located on the end of the segment, then the terminating resistor is
switched on the DP slave.
If the DP slave is located at the end of an FOC line, then the unused FOC interface must
be closed with a dummy plug.
NOTICE
when configuring with GSD file
When using an IM 153-2BA81 (outdoor) you must convert the user parameter "MLFB" to
6ES7153-2BA81-0XB0.
If you configure the ET 200M (IM 153-2BAx2) with a GSD file, the length of the
parameter assignment message frame (maximum 244 bytes) can lead to limitations in
the number of assignable modules.
