One way to do it is to have a PI Point that represents when the equipment is down. A simple 0/1 to represent equipment running vs not running would do. Then once every day, do a TagEQ over the last 24 hours, which would give you the daily total, and you can write that to a PI Point.
Alternatively, depending on how you determine when the equipment is down, you may be able to do the same without needing the first PI Point described above to represent when the equipment was down.
That definitely simplifies things. Thank you Stephen.

You're not alone in your need to be able to compute on EventFrame searches. There is a feedback item here that covers that: Aggregate event frames to a time series – Customer Feedback for OSIsoft & the PI System
