Hello,

I understand what is happening in the demo app - you are right, the passing there goes through the endpoint URL string and therefore the user info is lost.

Are you saying that you are using the user authentication with the Live Binding as well? You have not mentioned that in the steps taken.

Can you still send the details of the error ("..." -> Copy to Clipboard).

Thank you

Hello,

thank you for your answers. Unfortunately it still remains a mystery, so I apologize but I have to ask more:

1. When you tested with "traditional coding", was that from the same client computer as with Live Binding?

2. Can you send me both projects - the one with traditional, and the second with Live Binding? (zipped; can be attached to the forum post, or emailed). I understand that in the second case, you have not actually managed to create the binding, but I want to check whether something have not gone wrong in the project setup itself.

3. Can you please obtain details of the error and send them to us? To do so, locate the small "..." button left to the yellow error box. Click the "...", and a dialog appears with more information about the error. There is a button like "Copy to Clipboard" in the dialog - press the button, and then Paste the information (it can be quite long) to your reply.

Thank you in advance.

Hello,
thank you very much. [...]

Here my answers to your 4 questions:
1.)
Yes, I’m absolutely sure, that I edit the correct URL!
2.)
The server is a different device (S7-1500). The client is a windows 7 notebook with the IP 192.168.0.10
3.)
I entered the URL manually: opc.tcp://192.168.0.1:4840
If I browse the network, QuickOPC never finds the OPC-Server
4.)
If I start the connection on the entered URL, I get for a short time the infomessage browse… and after a few seconds it appears the errormessage „The requested name is valid, but no data will by found for the requested type
„ in the yellow windows at the bottom fot he dialog.

I hope, you can help me, because I hope that we can use OPC-Lab at the technicak schools in Baden Württemberg.

Best regards

Hello,
thank you for your interest in our products.

This is a weird problem (because it works with "procedural coding" - but the Live Binding is just a layer over that, so it should work then as well).

I have some questions.

1. Are you absolutely sure you have the URL of the server correct - equal to the one you used with the "procedural coding"?

2. Is 192.168.0.1 the same computer as where the client resides, or are the client and the server on two different computers?

3. How did you enter/select that URL in Live Binding/ Were you able to browse (discover) the OPC servers and then just pick the right server? Or have you entered the URL manually?

4. At which moment do you receive this error? Is it e.g. when you try to browse the nodes in the server, in order to select the node for the binding? Or at some different moment?

Thank you

I'm testing QuickOPC and I started with "Making a first OPC UA application using Live Binding". Everthing works fine with your "opcua.demo-this.com". But if I change to my Simatic S7 OPC-Server with "opc.tcp://192.168.0.1:4840" I still get an error called "The requested name is valid, but no data will by found for the requested type".

Whats my problem? If I start with "Making a first OPC UA application using traditional coding", everythnf works fine. Even with other UA-Clients.

Best regards

R.
