Is it possible to read local variable throungh OPC communication?

I am pointing to a different technology.
If you want your local variable to be exposed outside you need to have them managed by the IOServer and this means that you need either define it as part of an IO-DiskDev (quite old technology) or part of a device that uses Persist Memory (a caching mechanism) similar to disk device but more efficient.
