Greetings to all.  
I am new to Ignition programming, surely this question will have a simple answer. I am creating a SCADA and I need to take analog data from a field unit (RTU), with this data I need to create fifteen minute averages, it can be with a sample every 10s. These averages, later I will save them in a database to be processed by a small application. Thank you very much if you can advise me.

You will need to save the 10-second samples in a database. Then you can "process" the 10-second samples into the 15-minute averages, for prior periods, at the start of a new period. You can prune the 10-second samples any time after that.

Ignition's tag historian can be configured on the point or points of interest to do the 10-second samples. Generally, the 15-minute averages would be done by a scheduled script.

Pturmel, Thank you very much for the quick answer.  
Is the Schedule script at the Gateway level? Do you have an example of the script?

Thanks

Yes, and no. I generally do not use the historian in this fashion.
