5.8.24.1 DiscreteAlarmType

The DiscreteAlarmType is used to classify Types into Alarm Conditions where the input for the Alarm may take on only a certain number of possible values (e.g. True/False, running/stopped/terminating). The DiscreteAlarmType with sub types defined in this document is illustrated in Figure 22. It is formally defined in Table 105.
