Hello team, I am trying to set up a communication between a Siemens S71500 and a Beckhoff system. We have decided to us a siemens DP DP coupler since the Beckhoff system has a profibus network present.

I have configured the DP coupler on the Siemens part and used same config on the Beckhoff side. (All pictures attached). I also created a Db structure to collect data from and to the DP input and output sides.

My question is, how can I do data transfer from a DB to the DP coupler output side and also transfer data from the Input side to a DB in my project. The DB created has "optimized access". This I can change if it is necessary.

What instructions can I use to move these data from and to the DP coupler's input and output areas?

I am using a Siemens TIA V16 update 4.

I would also appreciate if there are any sample programs I can follow in TIA.
