Hello,

it took more time then I expected but we were able to do deeper investigation on customer environment and it look like there was probably problem with typo in node id. I created code sample just for this testing and it works as it should. Sorry for the false alert.

Best regards,
Radek Huber

In addition, please post here the error message you are getting when reading the node Ids that "does not work".

Thank you.

This should work. I would like to have a look at it.

Can you please provide:
- KepServerEX version number.
- QuickOPC version number.
- A code example that shows the problem.
- A corresponding KepServerEX configuration?

Thank you

Hello,

We were using your QuickOpc framework for both reading and the browsing. We obtained the node id by method BrowseDataNodes.

Hello.

It is not clear from your post how you use the obtained node ID string. In fact, I am not even sure you are writing about using it in some other QuickOPC API call. Or, are you trying to use it in some other OPC client?

KEPServer reading namespace problem was created by radek.huber
Hello,

We had an issue with one node ID during reading from the KEPServer. We tried to use node ID we got from the quick opc browsing. It was composed from namespace name, namespace index and string id. But we were not able to read this node. It started working when we deleted namespace name part of the node id. Have you encontered this issue with KEPServer? Also this was problem only for one node from the KEPServer. We were able to read other nodes using namespace name.

Best regards
Radek Huber
