I try to read Alarm Class from Alarm Storage by this code, of course in the beginning I define AlarmManagerClient, etc.

AlarmManager.g_AlarmHandler.GetAlarmsFromStorage( ...... );

FOR i:=0 TO iCountRowsFromHistory-1
itfIAlarm := arritfAlarmsFromHistoryAll[i];
itfAlarmClass := itfIAlarm.GetAlarmClass();
END_FOR

but itfAlarmClass is always 0 so I can't use itfIAlarm.GetAlarmClass().GetName() method

The rest of Alarm elements like timestamps, message, latchvalues, etc. have proper values.

Same behavior I see in simulation AlarmManager examle app from Codesys Store and in real environment with Wago PFC200 controller.
Maybe someone knows where is the problem and how to read proper itfAlarmClass value ?

Hi, I am trying to access active alarms in code(As alarm count variable updates only when we go to to alarm table frame in visualization). I wrote following code but it is not working:

VAR
iCountActiveAlarms : INT;
parritfActiveAlarms : POINTER TO ARRAY[0..0] OF IAlarm;
itfAlarmManagerClientAll : IAlarmManagerClient;
END_VAR

AlarmManager.g_AlarmHandler.GetActiveAlarms(
itfAlarmManagerClient :=itfAlarmManagerClientAll,
iCountActiveAlarms => iCountActiveAlarms,
parritfActiveAlarms => parritfActiveAlarms);

The Value is always 0.
Please help.
