Hi everybody,
I'm new with labVIEW but I need help to accelerate my studying progress to make one system, I've done, working.
I'm working with a cRIO and some AI and DI/O modules.
1) I have an analog signal input, an AI, that when it is below a fixed value, let's say for example 6, it will give a signal to a DO that makes the start for a pump.
2) My problem is that: when the pump starts, it must run not continuously but every let's say 20 seconds for 40 seconds.
3) When the signal from the AI is over the value of 6, the pump must stop.
I did a .vi that works fine with cRIO and AI, DI/O modules for the points 1) and 3). My problem is the point 2) if the pump starts I don't know how to make it "timered-looped" and to stop it when it has to stop (from the AI, signal beyond the fixed value)
I hope to have been clear.
Thank you very much for your help
