Hello,
I have an actuator that activates several times during my test. So in short 100=off and 100<is on.
So my plot looks something like I have attached.
Now I want to calculate the total time (which is on x-axis)when the system is below 100. This will be the total time that my actuator was on.
Could anyone please advise me on which fiction should I use to get to my result?
Kind Regards, Mustahsan

Try this:
totalTimeActuatorOn = sum(yourSignal < 100);

Thank you very much for your reply!
Yes this will give me the total time but it would be great if i could get duration between two peaks. So then I will know for how long it activates each time.
Thanks!
