Hi, I have a similar problem, there are two rexroth rmv-dp/f bus modules on dp network for some reason I downloaded the hardware config from an old backup and after that bus fault has appeared. at first I had the ???? for order number too but I found the gsd file from this link :

http://www.gsd-db.com/index.php?keyword=R.Bosch%3A+IO-interface+RMVDP%2FF

after installing this gsd, I faced a different problem 

I attached an image.

can you help me?

I think it's related to gsd, but I don't know how resolve the issue
