Configure automatic recalculation of analyses and analyses templates

Automatic analysis recalculation is available with PI AF 2017 R2 and later. Event frame generation and SQC analyses that are configured to generate event frames are excluded from automatic recalculation. An event is considered late if its timestamp is earlier than the last execution time of the analysis. The last execution time is the same as the timestamp of the latest triggering event in an analysis (event-triggered) or the last time an analysis ran (periodic).

Prerequisites: Although automatic recalculation is globally enabled by default, you need to opt in at individual analysis (template) level if you expect late-arriving or out-of-order data that may trigger recalculation. PI AF Server and PI Analysis Service 2017 R2 or later are required.

To configure automatic recalculation for a particular analysis (template), follow this procedure.

1. Go to the analysis (template) for which you want to enable automatic recalculation.

2. Click Advanced button at the bottom of the pane.

   Advanced options window opens.

3. Check the box next to Recalculate analysis for out-of-order input events and click OK.

   Note: You cannot opt in or out of automatic recalculation by accessing the analysis if it is based on a template. Go to the template to make changes.
