Communicate PLC 313-2DP to VLT 5000 (FC300) by Profibus

hello singlepersion;
If you go to the screen you sent us as error.jpg, where you see the drive in the Profibus network with an error symbol, double-click on the drive to open the diagnostic buffer to get the drive's error message. it should help you understand the problem.
I believe the error stems from the Universal module you have selected as interface between the drive and the DP master. Ithink that the Danfoss drives support Profibus telegrams of thePPOx types (look for that term in the Search box at the top of this page, there have been a few discussions of this on the forum, they could help you understand the issue). Once you understand PPOx telegrams, you need to select one in the modules for the drive, see the same error.jpg file, the PPO1 to PPO5 selections are shown on the right.

One member here(manmeetvirdi) asked for help on the forum on communications between a S7 Profibus master and a Danfoss VLT 5000 a few years ago:

He eventuallywrote a Step 7program that used a consistent PPO1 telegramand SFC14/SFC15 to control the drive (he put it up on another forum I participate in). You will find it attached below, study it as a basis for your own communication program.
You could direct any further questions on his program directly to him, i am sure he would give you gladly any help he can.

Hope this helps,
Daniel Chartier
