Hi,
I am upgrading prosys sdk from version 2.2 to version 4.3. In version-2.2 I was using “Identifiers.AnalogItemType_EngineeringUnits” and “Identifiers.AnalogItemType_InstrumentRange”. I could not find “Identifiers.AnalogItemType_EngineeringUnits” and “Identifiers.AnalogItemType_InstrumentRange” values in version-4.3. So I would like to know the corresponding values in version-4.3. Could you please help me on it.

Thanks.

Hello!

OPC Unified Architecture 1.04 Amendment 1: AnalogItem Types introduced a new VariableType called BaseAnalogType as a subtype of DataItemType. Previously AnalogItemType used to be a subtype of DataItemType, but now it’s a subtype of BaseAnalogType instead. As AnalogItemType inherits Properties of BaseAnalogType, like EngineeringUnits and InstrumentRange, there are no need for References to such Properties originating from AnalogItemType.

Prosys OPC UA SDK for Java implements this and other amendments, which is why the identifiers you were using with version 2.2 no longer exist in version 4.3. The corresponding identifiers in version 4.3 are “Identifiers.BaseAnalogType_EngineeringUnits” and “Identifiers.BaseAnalogType_InstrumentRange” respectively.

BR,

Matti
