View alarm quality

View the quality of alarms which is detected through controller faults. While there can be several faults or reasons that determine the quality of an alarm, each alarm is assigned only one quality -- good, bad, or uncertain. If there is no fault, the quality of the alarm quality is good. If the status of a controller status is not read yet, the quality of the alarm is uncertain.
