TP270 MPI over ethernet

[dugmick 0]

Hi all - I have some TP270s sitting on an MPI network connected to an S7-400 CPU, with a CP443-1 communication processor. I am trying to download to the TP270 by way of ethernet through the CPU to the MPI network, but it will not make the connection. Is this even possible, and if so, how do I set up the pass-through parameters to get to the MPI network? Thanks in advance!

Hi dugmick. Exactly that is not possible, except for the latest release of WinCC Flexible 2008. Routing like this is NOT possible (except for WinCC Flex 2008): (PC) --MPI or DP --> (S7) --Ethernet--> (HMI) (PC) --Ethernet --> (S7) --MPI or DP--> (HMI) Routing like this IS possible: (PC) --MPI or DP --> (S7) --MPI or DP--> (HMI) (PC) --MPI or DP --> (S7) --Ethernet--> (S7) --MPI or DP--> (HMI)
