Jason, take a look at this recent post on triggering back-to-back EF. The trick as you can see it to use the same start trigger and end trigger, but configure a time-true (true for) for the start trigger. Note, in my experience, the "true for" usually causes a lot of confusion and unexpected results:Issues with 'True for' in the Start Trigger of an Event Frame Generation Analysis
Try this: Start Trigger: (Hour('*') =6 or Hour('*') = 18) and Minute('*') <=1 (Time True For 1 Minute)
End Trigger: (Hour('*') =6 or Hour('*') = 18) and Minute('*') =0
Set the schedule type to one minute interval. I did a preview and it seems to work. Not obvious at all! Also, I assume your users can wait that one minute for the EF to appear.
Again, you can see this enhancement request: Easily create periodic event frames – Customer Feedback for OSIsoft & the PI System
Thanks Dan, I'll try and grok how to use that approach.
This functionality should be implemented in the 2018 release. We are currently working on the beta builds and we should have a customer technical preview (CTP) build ready soon. If you're interested in testing the 2018 CTP build in a non-production environment, reach out to Stephen Kwan.
I think Dan Fishman's solution will work as a workaround until the release or if you can't upgrade. Another workaround, is to have two analyses. One analysis creates the day shift event frame and one creates the night shift event frame.
StartTrigger: Hour('*') = 6
EndTrigger: Hour('*') = 18
StartTrigger: Hour('*') = 18
EndTrigger: Hour('*') = 6
