This ones got me really puzzled.
I decided to try out changing the DP-Station addresses, as mentioned in my other recent post. This involved re-addressing the CPU's DP Port to 26 instead of 2. However, the PC is connected via its CP5611 not to the DP Port but to the MPI Port, who's address has remained unchanged at 2.
When I tried to download the new version of the program I got a message that no active partners could be found. Since I hadn't changed anything as far as the MPI was concerned, this surprised me a bit, so I went back into HW-Config and checked everything over - it was all OK - then re-compiled it, just to be on the safe side. I then tried to download from HW-Config and as you can see from the screendump, the target has defaulted to the DP-Port at address 26. However, when I did a refresh, sure enough it found the MPI Port on address 2 and I was able to download the System data to the CPU.
So then I went back to Simatic Manager thinking that all would be well - but no change! It looks as though Simatic Manager is also defaulting to the DP-Port as well, but here you've no chance to search, it's just error message, end of story?
It was after this that I noticed some other peculiarities in the MPI Setup, but since that involves more Screendumps, I'll add that in another couple of Posts.
