Hi and thanks in advance for the replies.
I'm having troubles setting up an OPC-UA server via the Symbol Configuration panel.
As the title says I don't really know why but some of my GVLs are not showing up in the Symbol Configuration table.
I don't know how to solve this problem, I can't figure out why some GVLs are in and some are out, it seems to me like it's an arbitrary thing rather than an error. (The project compiles without errors)

Thanks again, Ryan

My guess:
You have not used the variables in your code, AND you have not ticked "Link Always" from the Build tab from the right click menu of the GVL.
