I have a Siemens S7-200 PLC and Simatic Panel TP 170A but I can't get them to "work" together.
I can program the PLC with STEP 7-Mirco and the Panel with WinCC Flexible but I can't get them to communicate afterwards.
Before there was a program on the PLC and the Panel and they communicated fine. When I Updated the Panel to 7.2.0.0 and made a program that reads from VD100 I get #########. (It's set to 4.4 on the PLC)
I'm using the MPI cable btw.
I'm kind of new to all this so it's probably something simple =)
