Dear Forum Members,
the picture below shows a temperature trend.
From this trend, I need to create the following Event Frames hierarchy:
Profile (Parent EF)
|_ Step 1 - CH1 (Child EF)
|_ Step 2 -PI (Child EF)
|_ Step 3 -CH2 (Child EF)
|_ Step 4 -MHT (Child EF)
|_ Step 5 -Ref (Child EF)
The Step 1 increases until 150°C.
During the Step 2, the temperature is around 150°C.
The Step 3 increases until 385°C.
During the Step 4, the temperature is around 385°C.
During the Step 5, the temperature decreases until 87°C.
With a PI Analysis, I am able to determine when the step 1 starts and finishes, when the steps 2 and 4 starts, when the steps 3 and 5 finishes.
If I determine when the steps 2 and 4 finishes, I will be able to find when the steps 3 and 5 starts and vice versa.
My difficulties is to determine when the steps 2 and 4 finishes or when the steps 3 and 5 starts.
So how can I finishes and starts a PI Event Frame at the moment where the temperature increases (step 2 to step 3) and decreases (step 4 to step 5)?
