I’m working on small project that uses OPC UA library to browse OPC Tags from the kepware server, the objective of the application is to browse all available tags and read their attributes (Description, Data Type, Access Level, Scaling used?). I follow the same code that used for UA Sample Client (C#), I found sample client doesn’t show the description field value, it shows empty string for that field alone, I’m unable to attach a screenshot here.

Can you see a description returned from the server? No all nodes have a description.

I can see description for all nodes in Kepware Ex Quick client and in the server, but nothing shows for any tags in C# OPC UA Client.
see this screenshot from the below link, the popup window is from C# Sample Client.

You will need to debug the code and verify that the client is:
1) Asking for the Description in the Read Request
2) Getting a Good result + Empty string
Also I am not sure that KepWare client uses UA to talk to KepServerEX.
Try a pure UA Client like UAExpert: https://www.unified-automation…..xpert.html
