How can I use PI data link to specify the AFCalculationBasis of Event Weighted, Event Weighted Exclude Earliest Event, and Event Weighted Exclude Most Recent Time, Event Weighted Include Both Ends, Time Weighted, Time Weighted Continuous, and Time Weighted Discrete? When I use Calculated Data of PI Data Link, I see two options for specifying the calculation basis. It shows “time-weighted’ and “event-weighted”. If I click the button to the right of the option it lets me key something in. The documentation doesn’t explain this option; it only shows time-weighted and event-weighted.
