Hi there
I've got a module in a project that has started 'faulting' (i.e. the Diagnostic buffer is full of errors from the module and OB82 is being called every time the module faults). The module errors are very short (a few seconds) and then the module reports "module ok" in the diagnostic buffer.
It seems like a spurious issue and I was going to change the module for a spare to see if it cleared. However, looking through the hardware config I noticed that there is also an Ethernet Lean card that is using the same diagnostic addresses as this module (1020 -> 1022 inc).
The hardware for this machine hasn't changed in years and this fault has only started occurring in the last few months so I don't think this is the problem but just wondered if anyone knew whether the diagnostic addresses need to be unique and whether its worth changing them?
Cheers
