Table 55 describes the details of the A & C Exclusive Alarming Server Facet. This Facet requires support for Alarms with multiple sub-states that identify different limit Conditions. This facet builds upon the A&C Alarm Server Facet. The term exclusive means only one sub-state can be active at a time. For example, a temperature exceeds the HighHigh limit the associated exclusive LevelAlarm will be in the HighHigh sub-state and not in the High sub-state. This Facet requires that a Server support at least one of the optional Alarm models: Limit, RateOfChange or Deviation.
