AC 800M Module Bus Fail Counters
The Module Bus Fail Counter from AC 800 M reports some device failures.
Initially there was some fail counters in the module bus.
Resetting the counter showed zero for all clusters positions. After a day I checked once again and the fail counters appeared again as in the file attached.
There is only one cluster in the modulebus with 101 DI830 module.
How to diagnose out what caused the counters to count up?
