M_ClearAlarm

This method deletes an alarm from the Admin-Tags. Alarm[].Trigger is set to FALSE. The method returns TRUE if the alarm was deleted successfully. The alarm remains in the Alarm array until an M_AcknowledgeAlarm 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.
