Alarms synch problem with two redundant operator stations
Two single node redundant stations (Operator and Engineer stations) work normally when both are on. Alarms are coming to both stations and can be acknowledged on both of them. Problem occurs when one station is restarted. Previously active acknowledged alarms become unacknowledged (blinking) but state says (AlarmChange column in list) “non-state” - they continue to blink and cannot be acknowledged. Problem is solved when both stations are again in operation and these signals are forced/blocked and changed state manually. After that, they can be ackonwledged and everything works normal again.
Question is:Is this a known problem, software issue, that is solved in some revision, rollup, etc.?
