8.23.3 ObjectType Description
8.23.3.1 Variable Reliability
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.
8.23.3.2 Variable Reliability_Evaluation_Inhibit
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.
8.23.3.3 Object FaultAlgorithm
This object, of type BACnetFaultAlgorithmType describes the BACnet fault algorithm used by the physical device.
