@xky0007 Can you try to use the model Compiler to generate an xml for use with the LoadFromXml method.
https://github.com/OPCFoundation/UA-ModelCompiler

I suppose this will maybe solve your issue.

@romanett
I followed the read.me and run .\Opc.Ua.ModelCompiler.exe compile -d2 .\1.xml -o2 .\output but got many files. None of these files contains the node BrowseName="1:Running".

And where can I find the difference for NodeSet and NodeSet2 definition? Thanks.

[romanett]

@xky0007 i am not familiar with how to create a valid UANodeSet file.
More information can be found here: https://github.com/OPCFoundation/UA-ModelCompiler/blob/master/Opc.Ua.ModelCompiler/UA%20Model%20Design.xsd

NodeSet2 shall be used for any new nodesets published if i remember correctly.

You can use the abc.PredefinedNodes.xml to intialize the predefined nodes.
