Hello all,
I am trying to read DB values from an S7-300 with CPU 317-2 DP. I have done this before with a CPU 313C but it had a CP 343-1 Lean comms module. The way this was previously done was by creating a Simatic PC station and adding a WinCC RT pro. application and ethernet comms module to the PC station. From there I was able to make a connection between the 313C and the PC station via TCP/IP. And through the WinCC RT pro. application I was able to create HMI tags and access the DB that way.
I have added a few screenshots for reference. My question is how can I achieve this with the CPU 317 which only has an MPI/DP comms port. I noticed that when I set up the connection in the WinCC RT app. I am able to select MPI as one of the interfaces. Would this work?
Any advice is much appreciated, thanks!
