Hi @Rickard_Odgren ,
Which hw do you have?
Could you upload SystemDump?
Sincerely I see wrong memory access, that can be related to your code (memcpy/memmove/strcpy/…) or system task/library. If the issue is related to system task/library you should see usually same pattern in the logger.
Any helpful information on the backtrace?
Have you already analyzed the issue with the profiler?
Do you have the same issue if you downgrade AR to 6.0, mapp View to 6.0, OPC UA c/s to 6.0? That combination in my experience is very stable…hehe.
Which language do you use for your code? ST/c/ladder? If the language is not c you can add Iec Check library, or maybe you already did that. This library implements checking functions for division, modulo operators, range violations, array accessing, as well as read/write operations performed on memory locations.
