help with LabVIEW framework

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

Each Module has a number of different channels on it.

The Pressure Switch DIO Module refers to which slot of the cRIO the module attached to the Digital Sidecar is in. The Pressure Switch DIO Channel refers to the channel number (printed in white on the Digital Sidecar) that the switch is attached to.

The relay module and channel are similarly defined.

They refer to the same piece of hardware. The "Module" selection is used to specify which cRIO Module (and thus which Digital Sidecar) is being used. The valid choices are Slot 4 and Slot 6; Slot 4 is the default that will be used if you don't wire anything to that input. The "Channel" selection specifies which DIO pin on the Digital Sidecar has the pressure switch wired to it.

What about the "Relay Module and "Relay Channel"?

Similarly, the "Module" selection indicates the slot that the cRIO Module is installed in, and the "Channel" selection indicates which Relay pins on the Digital Sidecar are connected to the Spike.

Thanks a whole bunch! About a half dozen other questions were cleared up by your responses.

Thanks again!
