Hi Vegard, this video not only shows how to add a single variable. It shows how to add Qt OPC UA to your project, how to instantiate a Qt OPC UA backend, how to connect to a controller AND how to add an OPC UA variable. It also shows how to integrate the variable with a Qt Quick based HMI. All this provides a base on which you can quickly build more complex applications (involving more variables). The video is structured in a way so that it shows some meaningful principles in 20 minutes. If you have 1000 variables you would build a little bit more abstraction on top - which unfortunately doesn't lead itself to a 20 minutes tutorial. Feel free to get in touch if you have specific questions. Kind Regards, Frank
20 minutes to add 1 variable from OpcUA?? How do I do it if I have 1000 variables?

This is c++ program not SCADA system with implemented tag management !!!
