Hi, I have created 100 numbers of history tags and I am able to get the online data from each tag. But when I want to see the history, data is not stored for some tags. Configuration of history tag is same for all 100 tags. There is no error messages. I have used easy chart & it is showing “0” data for some tags. What could be the reason??? ---

Assuming all the tag configs are indeed identical, here’s some troubleshooting steps. - Store history for this tag [Yes] - History Provider is provided and correct - Historical Scanclass - Are you using [Evaluate on Change]? If so what is your Historical Deadband, and are the values of the tags moving outside that deadband? - Check Historical Deadband Mode, try changing it to Absolute if it isn’t already and set Historical Deadband to 0 or 0.01 - Value Mode - set to Discrete - Max time between records - if none of the others work, set the max time between records to something like 5 minutes and see if you are at least getting entries into the database, even if you don’t think they are correct. Other steps - Make sure tag is enabled - If the tag belongs to a UDT, make sure it is enabled as well ---
