Maths channel with time dependency
You want a user formula that is "1" if boost pressure is greater than 0.9bar for at least 0.3 seconds, otherwise 0?
You cannot do what you what in a single step, it requires a few equations. I will show an example for a flag that goes high when speed is over 200kph for 3 seconds.
Maths channel 1:
So this is a simple flag, when speed is under 200 then 1, otherwise 0
Maths channel 2:
So when the speed flag is over 200kph, we ramp up, and reset when we are under 200kph. The result is this channel is a timer that shows the number of seconds we are over 200kph.
Maths channel 3:
Another simple flag
in this case it goes high if #2 is over 3 seconds.
