How can you get a UR to talk to a Profibus network?

Hi all,
I am currently trying to interface with a DMG Mori with a Profibus master robot interface and a DP/DP coupler I am having very little luck getting this set up.
My setup so far is as follows. I have a compact logix PLC talking to the robot via Ethernet/IP the PLC is also talking with an Anybus Xgateway that is setup to be an Ethernet/IP slave on one end and a Profibus slave on the other end. I have the robot to the PLC working, as well as the PLC to the Anybus Xgateway. where I am struggling is getting the Anybus Xgateway to communicate to the machine.
Am I using the wrong hardware? Is there an easier way to do this? Any help would be much appreciated!

I’ve never used Profibus but here is an article telling one way to connnect the Control Logic to Profibus.

After looking into the problem in greater detail I found that DMG Mori's documentation was wrong. The DP/DP coupler is for having a Profibus master to Profibus master, the coupler is a slave to both masters. switching my Anybus Xgateway to have a Profibus master on one end and a Ethernet/IP slave on the other end should fix my issues. Anybus part number AB-7800. the PLC is a 5069-L306ER Compactlogix.
