Hi,

Assuming that specification of your structure can be found in the Nodeset you can create your structure with the DynamicStructureBuilder (you can see an example on how to use DynamicStructureBuilder in the UaSampleServer sample method CreateMyStructureValue). Then you can create an array of your structure like so:

MyStructureArray := MyNodeManager.CreateVariable(‘MyStructureArray’);
MyStructureArray.DataTypeId := MyStructureTypeId;
V := VarArrayCreate([0, 9], varVariant);
// VarStructureCreate is in the unit ProsysOPC.UaVariants
V[0] := VarStructureCreate(CreateMyStructureValue);
V[1] := …;
MyStructureArray.Value := TUaVariant.Create(V);
