Hi, for about two years now, similar warnings have been appearing frequently and almost every two months in the event log of reductively programmed ac800f controllers, and at the same time the station is down and one of the controllers is out of run and connected. will be disconnected. In this regard, I replaced all the related hardware components and also thoroughly inspected the profibus communication path in terms of resistance, but the problem has not been resolved yet, so I ask you to provide me with documents regarding these warnings. Thank you Alireza Mousavi Nasab
The Event History and all other data available under the Web-Diagnostics is for ABB support L3 and L4 only. Just knowing which code is what will not help. The data needs interpretation with additional information and only support experts and R&D can do that.
If you want some high-level information about what happens in your system the please post the complete Diagnostics files (Button Write to File) for primary as well as secondary CPU and provide the information I have asked for the same topic in your other posts.
