I receive an error that I am not familiar with when adding a tag pen to click to graph.

I think I see the problem. There are no historians setup on the Vision gateway. It looks like the historian is part of the SQLBridge module, but that module is running on a different gateway without the Vision module. Is there any way to access the historian on another gateway from the Vision module? I can access the SQLtags without any problem.
