Hello ercanacar; You have a connection to your CPU 315-2DP (over Profibus) from your WinCC station? And you have a second CPU (313C) on another subnet (MPI) that you would also like to connect to WinCC. I think you have 2 options: 1. Use the CPU 315-2DP as a gateway, collecting the data from the CPU 313C using MPI you want to display on WinCC, and add the tags to your Profibus (S7 Protocol Suite) in WinCC; This is an interesting proposal if the amount of data collected from the CPU 313C is relatively s,mall, since it implies an extra load on the CPU 315-2DP's memory and communications; If you choose to go that way, I would recommend that you identify the data you transfer from The CPU 313C to the CPU 315-2DP as belonging to the 313C (symbol prefix "313C" for example) so you have no trouble identifying them when you read them in the WinCC Tags. 2- use routing functions that allow your CP 5611 to connect to the MPI subnet of the CPU 313C through the CPU 315-2DP,s Profibus subnet. In Siemens' parlance, routing allows interconnections between different subnets, MPI, Profibus-DP, Industrial Ethernet, through a PLC that has the available connections. https://support.industry.siemens.com/cs/ww/en/view/2383206 Once the connection to the MPI subnet is defined, create a separate channel in WinCC to your CPU 313C, over MPI, using the 313C parameters (node address over MPI, especially) to create a connection, and the specific 313C tags you want to use in your project. Hope this helps, Daniel Chartier |
