I’ve been looking at this problem on and off for several days. The table tool is only returning the first row of the selection date range and changes when I change the start date. I have independently confirmed the data is present using MySQL Workbench to query the database.
To check my sanity I have created a window with two tables on it - see below. The one on the left is pointing to a historical tag created by another user. The one on the right is pointing to my historical tag.
One difference between the two is that mine is using a historical tag from a UDT but I can’t imagine this makes any difference once the data is being stored. Another is that they are on different scanclasses. Again this shouldn’t matter.
History setup for the other guy’s tag.
History setup for my tag. (I am logging at 00, 15, 30 and 45 minutes past the hour.)
My scanclass is triggered every 15 minutes.
Can anyone give me some suggestions on likely misunderstanding on my part?
