Alarm stats results under different tag type

I am using the below expression in an IO/Calculation tag to get the number of critical and high alarms for the dependent tags

\AlarmManager.GetAlarmStateStats([PLC_01a]\Root)\ActivePriorities["0001"]

Most of the parent tags I get good results. Any ideas on why some results are invalid? Does this indicate there are no alarms configured in tags within the structure?

Or is it a matter of what type of tag the parent is? In one instance I get a valid result for the high alarm expression ["0002"] but not for critical? This parent tag type is Modbus Compatible Device.

Any insight is appreciated.

Thanks!

Have you tried the GetAlarmStat function? It should be available from the Function Selector in the Expression Editor.
