I know there is such a thing as a leased scanclass, and that seems to work if you have direct tag bindings on objects on a window. But I don’t have that. I have thousands of tags I need to scan, but don’t want them to be scanning when nobody’s looking at the drilldown screen that these tags populate.
So now it sounds like a driven scanclass right? Well no, I can’t do that because the clients are on the corporate side of a DMZ architecture, all read-only, so they can only write to local-scoped client tags. But a client tag is out of scope on the gateway server to therefore cannot be used as a driven scan class’s trigger. Anyone have a suggestion how I can have these thousands of tags update only on demand from a read-only client?
