Historic deadband for a string


I would like to log a string and give it’s history in a table.
But the string changes bit by bit.
My question is, if it is possible to save the string in history if it has’n’t changed in like 1sec so I’m sure it is changed totaly.


Not in 7.9 or previous versions. In 8.0 there’s a ‘Min Time Between Samples’ property on tag history.
Using tag history to store strings is always going to have limitations - we don’t attempt to do any compression or comparison between values.
