Hi Chad.....
I believe I had similar problems. Foxboro converted our Trends from Display
manager to Foxview/FoxDraw back in 2008 and often old descriptors, historians,
and engineering units would stay from the old graphics but were unwanted as
most of these changed. You could make a permanent change but still they'd
revert back after a couple of recalls. Very annoying but after I changed the
Foxview to a .g file and edit with a text editor and delete any "hist01" text
in our case and then convert .g file back to FoxView the permanent change would
correctly stay as "hist05" after that. Not saying you have the same problem
but it's something you could try.

Subject: [foxboro] Foxview trend reverting to wrong historian
Hi list,
I have a number of trends in FoxView that recently decided to go look for an
old historian and therefore not populating with data, here's the behavior:
1. If I right click on the dysfunctional trend, go to advanced, and go to
advanced pen 1 (2,3,4), under historian name it says hist01 (old historian
name).
2. When I open the same trend in foxdraw it is configured to hist80
(proper historian name).
3. Back in Foxview If I change this to hist80, select "permanent" under
save/exit choices, and refresh the trend it works at first.
4. I can open and close the trend and it keeps coming up hist80 and good
data.
5. Randomly(ish), I'll open the exact same trend and I'll get no data.
The advanced pen screen shows again hist01. Foxdraw still shows it's
configured as hist80. Some of the trends I fixed are still working, others
reverted back, I can't pick up a pattern to the madness.
Has anyone experienced anything similar or have an idea to try?
