M_AcknowledgeAlarm

This method acknowledges an alarm in the Admin-Tags. Alarm[].Trigger is set to FALSE and the value from Admin.PlcDateTime is entered in Alarm[].AckDateTime. The method returns TRUE if the alarm was found and acknowledged successfully. Acknowledging the alarm does not delete it. The alarm remains in the Alarm array until an M_ClearAlarm has been called, then it is moved to the AlarmHistory array. If the AlarmHistory array is already full of entries, the oldest entry is deleted as a result.

So that a valid timestamp can be entered, the function block PML_AdminTime should be called cyclically in the program.
