Bacnet property present value

This OPC UA Variable , of DataType Float , indicates the current value, in engineering units, of the input being measured. The Present_Value Variable shall be writable when Out_Of_Service is true.

This OPC UA AnalogItemType Variable represents the BACnet properties Present_Value, Min_Pres_Value, Max_Pres_Value, Units and Update_Interval. The OPC UA VariableType AnalogItemType is defined in OPC 10000-8 . It defines the OPC UA Properties EURange , EngineeringUnits and InstrumentRange .

The following list provides the BACnet property and the mapping to the corresponding data member in the OPC UA AnalogItem.

Present_Value represented by ValueAttribute of the Variable .
Min_Pres_Value represented by Low part of EURangeProperty of the Variable . If the optional BACnet property Min_Pres_Value is not present, the EURangeProperty should not be provided.
Max_Pres_Value represented by the High part of EURangeProperty of the Variable . If the optional BACnet property Max_Pres_Value is not present, the EURangeProperty should not be provided.
Units represented by the EngineeringUnitsProperty of the Variable . The mapping of BACnet units to OPC UA units is defined in 11 .
Update_Interval represented by MinSamplingIntervalAttribute of the Variable .
