Hello,

I'm new to QuickOPC, and I'm a bit frustrated. QuickOPC does not seem to be so simple as stated on the Homepage.
I'm working with Delphi Berlin and tried this really very simple code (a simple modification of the supplied demo):



procedure TForm1.FormCreate(Sender: TObject);
var
EasyUAClient: TEasyUAClient;
begin

EasyUAClient := TEasyUAClient.create(NIL);

Edit1.Text := EasyUAClient.ReadValue('opc.tcp://PLACEHOLDER:4870',
'25_SPS->CC.behaelter_a.level.level_act');

end;


Starting this little program, it throws the following exception:

"Unexpected signature algorithm:."

The same OPC-Server responds absolute correctly when I use the UAExpert Client (OPC Foundation)
Any Idea?

Regards,
Martin
