I also have a question:
When opening the compressor in the BEGIN sub-VI, what is the difference in the "Pressure Switch DIO Module" and the "Pressure Switch DIO Channel"?
I know they refer to different pieces of hardware (digital sidecar and pnematic breakout), but which one? Do I need to use both of them? What about the "Relay Module and "Relay Channel"?

Thanks
