Create Opc Ua Serveur c# with custom structure Slot|OPC UA Standard|Forum|OPC Foundation

Hello,

I would like to create an Opc Ua server with a customized structure:

<UADataType NodeId="ns=1;i=3003" BrowseName="1:SlotType">
<DisplayName>SlotType</DisplayName>
<Description>Slot Type</Description>
<References>
<Reference ReferenceType="HasEncoding">ns=1;i=5001</Reference>
<Reference ReferenceType="HasEncoding">ns=1;i=5003</Reference>
<Reference ReferenceType="HasEncoding">ns=1;i=5002</Reference>
<Reference ReferenceType="HasSubtype" IsForward="false">i=22</Reference>
</References>
<Definition Name="1:SlotType">
<Field DataType="Int16" Name="ProductId">
<Description>Product Id</Description>
</Field>
<Field DataType="String" MaxStringLength="2" Name="ProductName">
<Description>Product Name</Description>
</Field>
<Field DataType="Int16" ValueRank="1" ArrayDimensions="3" Name="Location">
<Description>Location</Description>
</Field>
<Field DataType="Int16" ValueRank="1" ArrayDimensions="3" Name="Rotation">
<Description>Rotation</Description>
</Field>
<Field DataType="Int16" ValueRank="1" ArrayDimensions="3" Name="Dimension">
<Description>Dimension</Description>
</Field>
</Definition>
</UADataType>

I want a Pus folder with a PuIn Object inside, containing a list of 24 slots of type slotType.

I've tried to generate the model with UaModel or Ua Model eXcekerator Pro.
I can't create this c# server with the OPCUa Foundation library. In the case of UaModel, the nodes don't seem to be present and with UMX, the slot list is not initialized.

I tried to create the IEncodable object directly, but the client doesn't decode it.

Do you have a simple example of how to do this?

Thanks in advance.
