Hello arashbo; One quick trick, that might give you indications on the network status, since you have many entries of the Distributed I/O, Station Failure type all happening around the same time: Open your Hardware configuration, go online, and check which and how many of the Profibus slaves in your network appear with an error icon (a red slash). If all (or a great number) of them are marked in error, you could be experiencing a termination fault. That means that on the first and/or last (physical) station on your network the termination circuit on the Profibus connector) is either at OFF (they must always be ON on end-nodes) or the node has lost its 24 VDC power. You should also have a look at this very short and non-technical article; it does state that Termination problems are the number one cause of Profibus network failure,,, TOP 5 REASONS YOUR PROFIBUS NETWORK FAILED https://us.profinet.com/top-5-reasons-your-profibus-network-failed/ Come back to us with the results, we may be able to help you further. Hope this helps, Daniel Chartier |
