It turns out it was because I opened DIO 1 after it was already assigned to the compressor.

Also I forgot to do Compressor Start during Begin.VI.

I also discovered that the DIO returns True when the switch is open (e.g. when the switch is completely unplugged).

We have the regulator and rest of the pneumatics line working. We have the low pressure side running at 60 PSI. We have one of the Festo VPLE18 single solenoid valve, but when we try to activate it the LED turns yellow, but the valve doesn't seem to do anything.

We have the solenoid output connected to 1 and 2, SIG being connected to 2. We already tried 1 and 3 and that makes it worse (the LED doesn't turn on at all). The solenoid activates with the manual override.

In labview, we tried Solenoid Set and we tried On, Forward, and Reverse. I'm a bit confused because I thought solenoids could only go one way, and double solenoids can only go 2 ways. What does the On setting do? Why isn't the solenoid moving?
