Dear All The attached is the configuration of Profibus DP network for S7-400H system. Y-link is used to communicate to the remote Profibus DP transmitters. Since the remote transmitters are in far location OLM (Profibus->FO) is used. In the same remote location there are few Profibus PA devices and that needs to be communicated to the 400H system. Whether a DP/PA coupler can be used in the Y-Link network in the remote location? I have three such remote locations. If not what kind of configuration required to fulfill the purpose? Can anybody help me out in this. Regards, Kanag AttachmentSYSTEM Model.pdf (276 Downloads) |

Hello Kanag's just in case you'd like to run the DP side behind the Y-Link at "normal" DP speeds, you can go for a GSD file basedconfiguration of a(IM153-2 or 157) DP/PA link (the so called metadata basedconfiguration does not allow you to place a DP/PA link downstream of a Y-Link for reasons that somewhat elude me). Have a look at the link below and get hold of the so called GSD tool (link to it is inside the link below) which youneed to create the DP/PA links GSD file (it's a bit "messy" compared to metadata based DP/PA link configuration but that's the price you'll have to pay). How do you configure a PROFIBUS PA network in STEP 7? Attached isalso a pic that should help in making sense of the above and don't forget to"inform" the DP bus that you usea FO ring so it can adjust the busparameters accordingly. I hope this helps |
