Hello,
thank you for your interest in QuickOPC.

Basic example of subscribing to OPC UA variable:
opclabs.doc-that.com/files/onlinedocs/QuickOpc/Latest/User%2...de%20for%20data%20changes.html

There are many other examples available.

It is also possible to "bind" to POCO (Plain Old C# Objects), we call it "Live Mapping", but frankly, for most usages the easiest is the approach closer to the example above. It all depends on the use case.
Live Mapping: opclabs.doc-that.com/files/onlinedocs/QuickOpc/Latest/User%2...e.html#Live_Mapping_Model.html

I hope this helps. Let me know if you need more.

Best regards

I downloaded and installed quick OCP UA and I can run the demo, but I cannot find how to integrate this into my existing c# project. Do I have to purchase a licence before I can trial the integration? In the project I can either integrate a client to communicate with an external OPC UA Server or have both the Client and Serve on the host PC so I can communicate with any PC. My environment is C# WPF, but I don't want to bind to a display variable, I need to bind to variables within the C# code .I simply want to read and write data from and to a target PLC.
Hope you can help

Thank you
