Is it possible to make System/gateway/performance tags historical? I tried just adding history and that didn’t work, perhaps making a new memory tag for each and reading from the system tag to that and then storing history on the memory tag… any other suggestions?
Could you provide a little more detail on what 'didn't work' means? Because you definitely can just store history on system tags:
I have the history symbol shown as you have, then I added the historical tags to an easychart and nothing is displayed. I have other tags coming from OPC, and trending there is no issue.
It’s always worked for me, too. /-:
