Dear all, I am wondering weather someone can help me out, Namely I have two S7-300 CPU315-2 who are connected thru CP342-5 so they X2 port (profibus DP) are connected to the extension IO backplanes IM153. X1 port on both CPU units is connected to the HMI units. So I am trying to connect PC to the CPU's using PC adapter. If I try to connect over the X1 port MPI I can go online with the PLC can do upload from the PG to PC. But if I try to monitor values it is not working also I cannot force value neither I can download any change. Also in the VAT I can see actual values for the variables and they are updating but if I try to force value it does not working (force pushbutton release on its own). ------------------------------------------------------------------------------------------ |
