Solenoid Valve Issue

Very good that the solenoids works via direct so it tells me that either the bumper/module is bad or your software is at fault.

Have you checked the voltage at the bumper outputs without the solenoids connected? This will give a good idea where to look next.

The bumpers have been checked and function properly

When you say the bumper functions correctly is that with a voltage output check only with the software toggling the outputs?

Please do an OHM resistance check on all the solenoid coils.

I just re-read your OP, what green light flickers?

Oh, something else just came to mind. Do you have the solenoids plugged in correctly? Example, is ground at ground and voltage at voltage. Just have to ask as I saw it once before.

Good luck with your problem. I hope you find it as I'm login off now.

Are you sure you have the solenoid module in the correct slot on the cRIO? If you have a 4-slot, it should be in slot 3 or 4, in an 8-slot it should be in 3 or 7
