How to configure Siemens DP/DP coupler in Compact control builder?
I am trying to connect Siemens CPU315 to ABB PM851 using profibus. I have a Siemens DP/DP coupler which I have imported to Control builder by its GSD file.
I need help in configuring the coupler in control builder. Can anyone give me some guidance how to do that?
Thanks in advance,

I have done one similar project of this type. Collecting the data from Seimens PLC via ABB controller and sending the data to UMC100s and viceversa using Compact control builder.
Connecting the DP-DP coupler to PM8** via CI854 Profibus module
The configuration which I followed is below:
The configuration of the DP/DP Coupler is implemented as 16 bytes inputs consistent and 16 bytes output consistent unsigned.
All signals are assigned as a 2 byte to DINT unsigned and then decoded to status/control bits, and mapped to their sending/receiving location.
Byte swapping will be required for all signals due to communication between Siemens and ABB PLCs.
So, commands received from Siemens PLC
will be received as DINT, decoded in to status bits, mapped to each UMC100 function block and transmitted as a DINT Unsigned to the UMC100.
Status from each UMC100 will be received as DINT, decoded as status bits and re-transmitted to 3
rd party nodes as DINT signals
