1) I am assuming that we connect to a spike relay again (please correct if I am wrong)
2) Where do I connect the PWMs?
-Digital Sidecar with PWMs for motors?
-special place on the CRIO modules?
If anyone could help that would be amazing! I just remember how to do it with the old controls.
Thanks so much!

1. The compressor is attached to the spike relay for turning on and off. You will need the electronic pressure switch to have the automatic shut off once the pneumatic zone reaches 115/120 psi.
The solenoids (ex. FRESCO, SMC) connector (two pin female) should be connected to the solenoid breakout on the cRIO (slot 7 or 8).
2. Are you talking about regular PWM cables? They go to the Digital Sidecar. The ones for the motor controllers go the the PWM side. Spike relays go to the Relay "zone". Some sensors go to the Digital I/O "zone". The cRIO modules, (ex. Analog Breakout) takes a PWM cable for certain things, such as the potentiometer (I believe).

We are using 6 double solenoids so after using all the ports on the Solenoid Breakout we have 2 un-wired.
Is it legal to power them the pre-cRIO way, Spikes off the power distribution board?

I believe that you can put another cRIO module in slot 7, and then have another solenoid breakout there. You might want to check the rules on that though...
Hope this helps.
