Hello Everyone:

I have a couple of weeks trying to build a nice model design for a project with the following Architecture:

  • Root (BaseType-FolderType)
    • System1 (BaseType-Machine)
      • Machine (BaseType-Component)
        • MovingUnit (BaseType-FolderType)
          • MovingUnit1 (BaseType-Component)
            • Some Parameters
            • General Component (BaseType-GeneralBase)
              • Some Params
              • GeneralBase (DataType: ua:BaseInterfaceType)
                • Params
        • MovingUnit10
    • System2

My problem is when i compile it using the model compiler from OPCFoundation Model Compiler, My nodeset2.Xml file is over 1MB size....

and i wanted to do the same that I did for moving units for another 4 systems....

This is my first model design so feel free to take a look and please tell me some ideas and solutions.

Some General questions:
Can I use an structure of objects? it compiles but when i connect to the server, the objects are not there.

How can an array of Moving Units for example can be implemented?
Does somebody has a list of the Object, Variable, DataType available BaseTypes? The documentation is too complex and i would like to know what am i allow to use?

I couldn´t attacht my ModelDesign.XML but here is the code

The NodeSet is primarily used for defining types. If you use it for instances you will get huge files. 

The nodes you defined need to be linked to a well known node such as the Objects node.

If they are not linked they will not appear.

You can look at this example to illustrate how to add model design defined instances into the server address space:
