This OPC UA ObjectType represents a set of variables related to the BACnet fault evaluation concept.

This OPC UA ObjectType covers BACnet reliability evaluation. Parameters for BACnet fault reporting are covered by BACnetEventReportingType.

The BACnetFaultEvaluationType is formally defined in Table 68.

The BACnetFaultEvaluationType ObjectType is a concrete type and can be used directly.

This OPC UA Property, of DataType BACnetReliability, represents the BACnet property Reliability. The BACnetReliability DataType is defined in 10.4.28.

It provides an indication of whether the Present_Value or the operation of the physical I/O in question is “reliable” as far as the BACnet Device or operator can determine and, if not, why.

This OPC UA Property, of DataType Boolean, represents the BACnet property Reliability_Evaluation_Inhibit.

It indicates whether or not reliability-evaluation is disabled in the object.

This object, of type BACnetFaultAlgorithmType describes the BACnet fault algorithm used by the physical device.
