Helllo tsavnik; Did ths network ever work well, or did it fail as soon as it was tested? You seem to have done some research and troubleshooting on this problem, you shuld be commended for it. I would suggest you lok at Gabriele Corrieri's post in the Control .com thread, he proposes a way to examine the signals coming out of your integrated DP port with a 2-channel oscilloscope and verify if they are correct. https://control.com/forums/threads/siemens-s7cpu-cant-see-slave-dp-on-profibus.40352/ If you can do this test and it shows correct signals, then you have to continue with standard troubleshooting techniques, as shown in this PI (Profibus International) document: https://us.profinet.com/top-5-reasons-your-profibus-network-failed/ Hope this helps, Daniel Chartier |
