Pneumatics HELP

[chriz4gx]

So I know some basic labview like programming a motor, drivetrains, and some sensors. This year my team is using Pneumatics. I have literally no clue how to program that. One of my teachers told me that we are limited to 120psi in the compressor but how are you suppose to limit it. We also want it that when the cRio detects that the pressure is decreasing that it starts the compressor again and stops at 120psi. I have looked at the examples provided by NI but don't quite understand them. Can someone please upload an example on how to set up Pneumatics and control the PSI in the Compressor and also please define some of these "Pneumatics" terms such as double solenoids, spikes and etc not exactly sure what they are or the role they play.
