First of all, I'm newbie in PI development. Currently I'm getting summary values using calculation/getsummary controller. Now, I need to know how much time a summary has been over (or under) a threshold during the interval between startTime and endTime. I guess I need to supply an expression, but have no idea about how to write this kind of expression. Anybody can help or guide me about how to write expressions?


Thanks in advance
