Model design for the usage of events|OPC UA Standard|Forum|OPC Foundation

Hello together,

I have a question regarding the model design in order to be able to use events on my OPC-UA Server (.NET, 1.4.363.0).

My model is built from two .xml files – using the Model Builder: 

• an Instance Design
• an Type Design 

In my types design I have created own object types, e.g. “ExampleEventType” which has the BaseType “BaseEventType”.

My model should have the following structure:

• A (root, entry node; type: object; SupportsEvent = true) 
  • B (type: object; SupportsEvent = true)
  • C
  • D
  • ..

For example the node “B” should be able to raise an event from type “ExampleEventType”

Is it right that:

• “B” has a GeneratesEvent reference with target “ExampleEventType” 
• “A” has a HasNotifier reference with target “A_B”
• The event is constructed, initialized, gets set its child values and is reported by the server as shown in .NET Example “Quickstart SimpleEvents Server”

Forthermure, I am wondering why the Alias GeneratesEvents is not listed in NodeSet2.xml, although it is used in the file.

Thank you very much for your help!
