Hi,

(Assuming it is the 1.00 version of https://opcfoundation.org/developer-tools/specifications-opc-ua-information-models/isa-95-common-object-model/ that was released in 2013.)

That model has some errors, i.e. it is not done according to the OPC UA specification. There is a release candidate (in the archives on that page; 1.01.00), which fixes some of them. I’m not aware of any releases of that. However there is (some) NodeSet file in https://opcfoundation.org/UA/schemas/ISA-95/1.0/OPC.ISA95.NodeSet2.Nov52013.xml which apparently has some fixes, if possible please try that one.

Errors (based on quite old notes I had for the model) :
– GeoSpatialLocationType is defined as the subtype of PropertyType, but the standard UA spec is clear on e.g. version 1.04 Part 4 section 7.3. “PropertyType” that “It is not allowed to subtype this VariableType.” (Properties are handled a bit differently than any other Components of a node)
– Model is missing SymbolicName entries for nodes that do not have a valid code identifier in BrowseName that could be used as a class name (codegen 3.1.8 should be able to guess some names, previously this was a blocking problem)

Therefore I would recommend contacting the foundation / companion specification group for the ISA-95 model and ask them to make a release 1.01 of the spec with fixes.
