The DataValue Variable contains the analog Process Value as transmitted in the telegram signal.
The optional EngineeringUnits Property of the DataValue Variable shall be provided if possible and meaningful. If not, as in case for direct raw A/D conversion values and similar, the EngineeringUnits Property shall not be provided.
The optional EURange Property of the DataValue Variable shall be provided only if the EngineeringUnits property is provided. The optional InstrumentRange and ValuePrecision Properties of the DataValue Variable may be provided if possible and meaningful. This may be the case if the Server is running directly on the Device.
The Value of the QualifierValue Variable contains the qualifier bit. The optional Quality component of the QualifierValue Variable contains the status information encoded as RioQualityEnumeration.
RioFaAnalogProcessValueDataType Variables are linked to the associated PnIoSignalType Object in the PROFINET aspect using a 0:RepresentsSameEntityAs Reference.
