This is my NodeID: of the Execute (where I want to send the Command): ns=1;i=8223
Because I think, it will not work like this:

…
NodeID:=UAClient.NamespaceTable.ParseNodeId(‘ns=1;i=8223’);
UAClient.WriteValue(NodeId, String(‘SendDig1 500’));
…

Or might I need to do this with a kind of call(execute) routine ?

Thanks alot for any help.

Thanks alot for your help !

How might I need to declare this call ? UaClient.Call(ObjectId, MethodId, InputArguments);

In a simple way (due to it is only for 1 command – repsectievly to execute the call of SendDig1 500), would it be something like:

NodeID:=UAClient.NamespaceTable.ParseNodeId(‘ns=1;i=8223’);
UAClient.Call(NodeID, NodeID, String(‘SendDig1 500’));

(I could send you a picture how it looks like in the UAexpert)

Thanks alot !

Hello, sorry to bother, I tried it but I will receive a Violation Exception:

Seems, I do not understand the routine call proper

I just wanted to add also: According the UaExpert: the BrowserName is: 1,”execute” and the NoteClass is: Method, NodeId is listed (for the Execute): ns=1;i=8467 and NamespaceIndex is: 1

(Something with the ObjectId, I make wrong…)

Here the code:

procedure TForm1.Button5Click(Sender: TObject);
var
ObjectId: TUaNodeId;
NodeId: TUaNodeId;
Refs: TArray;
InputArgs: TArray;
OutputArgs: TArray;

begin
NodeID:=UAClient.NamespaceTable.ParseNodeId(‘ns=1;i=8467’);
Refs := UAClient.AddressSpace.Browse(NodeId, bdInverse, Id_HasComponent, False, [ncObject]);
ObjectId :=Refs[0].NodeId;
SetLength(InputArgs, 1);
InputArgs[0] := ‘SetParam1 100’;
OutputArgs :=UAClient.Call(ObjectId, NodeId, InputArgs);
end;

No, sorry – I just sent tried to send the call argument with the UAexpert. Here – under the Execute (call) it works.
Smething I make wrong with the ObjectID:=Refs[0].NodeId
