Represents the BACnet fault algorithm FaultState parameters.

The FAULT_STATE fault algorithm detects whether the monitored value equals a value that is listed as a fault value. The monitored value may be of any discrete or enumerated datatype, including Boolean. If internal operational reliability is unreliable, then the internal reliability takes precedence over evaluation of the monitored value.

For more specific information about the fault algorithm, consult ASHRAE 135 13.4.5.
