Gateway: Ignition Edge 8.1.12
The customer gutted an old system to set up a small test plant. There is no store and forward being used to a central server.
I have tags in the PLC that are only updating every hour on the hour (every o’clock). The customer is using the AdHocTrends chart to export data every day for personal logging purposes. One would expect the tags to record once every hour for a total of 24 data point a day. What is actually happening is multiple data points every hour. This requires a little more manual manipulation of the data the customer would prefer not to have to do.
The three tags in question are set up the same way in the designer. Am I not setting up the historical settings for these tags correctly, or is there a setting somewhere else that I am missing? The tags seem to record every 5 mins, but it’s not exact or the same every time. Changing minimum time between samples to something like 30 mins does not seem to affect the tag historization either.
