Hi,

I´m currently evaluating the OPC UA & Classic SDK for Delphi v7.5.0 Build 802 using the Embarcadero RAD Studio 10.1 Berlin.
I managed to run a sample OPC UA server, but I have a couple of questions:

– is the “Opc.Ua.NodeSet2.xml” file mandatory? The application throws an exception when I prevent it from loading that file. As far as I understood its content defines the Namespace 0.

– I cannot create a folder in my own namespace. When I call the “CreateFolder” method on my node manager it throws an exception (“NodeFactory: No type definition registered for type: TUaFolderType.”. This is how I call the method:
TUaServer* srv = new TUaServer();
// lots of initialisation
TUaNodeManagerUaNode* mgr = new TUaNodeManagerUaNode();
mgr->Server = srv;
mgr->Namespace = TUaNamespace::Get( “http://mycompany.com” );
srv->AddNodeManager( mgr );

TUaFolderType* folder = mgr->CreateFolder( “Folder1” ); << throws the exception

– how do I search for a node by Name? I need to create a device node by calling "CreateObject()" on the node manager, but if I call the function again with the same name the application throws an exception because there is already a device with that name. I searched the HTML and CodeInsight help for a method that allows me to find a node by its name, or even a list of nodes so I can find it myself, but there seems to be no such functionality, at least none to search by name.

– how do I find the namespace details for a given namespace id? When looking at the variables provided by my OPC UA server with an OPC UA client, the node Ids read "ns=2,s=Variable 1". How do I get the namespace information for namespace with index 2?

Kind regards,
Guido
