Hello,

I’ve enabled tag history on all of my OPC connections’ “Connected” tag.

I’m finding that the powerchart will display the incorrect value for these tags. For example, here’s one of them with the value of True:

And here’s what it looks like in the Perspective power chart:

Does anyone know what the cause of this might be?

Just a thought, but perhaps create a new “Reference” type tag that points to these Connected tags and add the historian to these new reference tags. I do this, but on all my gateway network connected systems and it graphs correctly.
