Hi, I am programming a new 412-3H system with a TP177a. I did not realise at the time of ordering that it has only one MPI/DP port available per CPU so now I have to use the same profibus network for ET200m station and for switching of TP177A using a couple of repeaters (as defined on the forum). I have done itsuccessfullybut the only problem I am facing is that each time when i switch the CPUs from active CPU to standby CPU (manually by stopping the active CPU)which then switch the repeaters the communication between TP177A and other active CPUis not established until I restart the TP. i mean every time I switch the CPU I also have to restart the TP177A to get the communication connection working. Please see the attached system config I have not mentioned the power switching of repeaters in this. AttachmentSystem.pdf (223 Downloads) |

Have you seen the following? How do you connect an operator panel (WinCC flexible) to an H system (S7-400H)? |
