I need some help on this scenario.
I have three tags:
Inferior Limit (IL)
Superior Limit (SL)
Tag Value (TV)
I need to calculate total time where TagValue is greater than superior or TagValue is lesser than inferior limit.
So i setup an analysis where:
timeGreater = timeGT('TV',starttime,endtime,'SL');
timeLesser = timeLT('TV',starttime,endtime,'IL');
dTime = timeGreater + timeLesser
it works fine, when i know starttime and endtime and input it via PI System Explorer.
But, now i need to put it on web application and set starttime and endtime on runtime. How can i do that ?!
I'm trying to use AFAnalysis to input (starttime, endtime), run then analysis and get the results... is that possible ?!
it's the correct way to do it !?
