Regardless of the current hierarchy level of the Nrio Point Manager view, whenever in Learn mode, the top Discover pane always reflects the availability of all I/O hardware points. In other words, if you are in the manager view of a points folder RTU2, and some points on the controller are already mapped to proxy points under other point folders, they will show as unavailable (dimmed). This prevents creation of multiple proxy points for the same I/O terminal, which is invalid. Of course, you could manually duplicate an existing Nrio proxy point, but the duplicate point would have a “fault” status, along with an explanatory “Fault Cause” explanation.

Note that this Discover pane behavior is different than in most other drivers, where availability in the Discover pane applies to the current hierarchy level only (discovered items show available even if already proxied under another points folder branch of the Points container).

In any Nrio Point Manager view, the Database pane always lists all Nrio proxy points in that hierarchy level and lower, if applicable. In other words, all Nrio Point Manager views keep the “All Descendants” mode engaged (you cannot toggle it off).

So, when looking at the top-level Points point manager view, all Nrio proxy points and Nrio point folders will be listed. If looking at the point manager view for Nrio points folder RTU2, any Nrio point folder children it has (say, Inputs2 and Outputs2) will be visible, along with all Nrio proxy points in all those Nrio pointt folders.

Any Nrio point folder shown in the Database pane of the Nrio Point Manager can be a target for adding discovered I/O points directly to it—without going to its own Point Manager view. In other words, click the target Nrio point folder to select/highlight it, then Add the discovered point(s) to create the proxy point(s) in that selected folder. Note that this behavior is also different than in most other drivers, where after adding, often you need to move points to different point folders.
