Hallo,

We want to import different xml models into the OPCUA Server address space. For Modelling we are using the unified automation OPC UA Modeler tool.

When the local server is filled with xml models generated out of one modeling project, the models can be loaded successfully without any problem . The problem occurs when the xml models are generated out of different modeling projects.

For example:

Project A Project B
0:OpcUA basics 0:OpcUA basics
1:Base model 1:Base model
2:Sensor A 2:Sensor B

At the beginning the local server has the OpcUA bas model per default and our base model gets imported.
Now the Sensor A model with namespace 2 gets imported.
When the Sensor B model from project B should be loaded, it has also namespace 2 including all references.
When there are two identical ids in namespace 2 of Sensor A and B, the according node doesn’t get loaded and thus the model is corrupted
because other references could end up in the wrong node (of Sensor A).

Is there a way of solving this issue with the SDK?
We thought of changing the namespace id for the conflicting namespaces.
Any suggestions?
