I created a tag historian binding to a table, when looking at the data in the table for today the value in the table doesn't match the value currently shown in the tag browser.
You've probably gotten deadband style "analog", which holds the most recent value in memory, and only stores to the DB when the trendline/deadband combination bends. (Deadband style "auto" selects "analog" if the data point is floating point.) Force the use of deadband style "discrete" to get immediate storage of qualifying new data.
Documentation:
I changed the deadband mode to discrete but am still getting different values in my table
My current settings for history
Your sample mode is Periodic, 60 seconds. It isn't even looking for changes. Check your minimum time between samples to determine why it is sampling at two minutes instead of one.
