Pretty new to ignition design and I am having an issue figuring out an upcoming project.
I have no problem with tags, historical and charting for tags that are constantly being polled like a pressure reading or other like that. What I cant seem to figure out is how to get point data saved with having the same data be populated into the historical sever every poll cycle. What I want is to have a data point entered in an HMI and have that point and only that point and timestamp recorded into historical so that I can trend measurements over time.
You can set the
Historical Scanclass to
<Evaluate On Change>, this will only log the history when the value changes.
