The Value of the Variable contains a temperature value provided by the Server. The Server might provide the optional InstrumentRange and EURange Properties of the 0:AnalogUnitType the TemperatureVariableType is derived from.

The WarningThreshold Property contains a temperature threshold causing a fault buffer warning entry if the temperature value exceeds this threshold.

The FaultThreshold Property contains a temperature threshold causing a fault buffer error entry if the temperature value exceeds this threshold.

The engineering unit used for the Value of these two Properties shall be equal to the engineering unit used for the Value of the TemperatureVariableType Variable and indicated by the EngineeringUnits Property.
