Re: Pneumatic Piston using Labview will not fire

So it sounds like the solenoid output is activated by the PCM if the side RED LEDs are turning on. To be clear I mean the LEDs mentioned in Section 3.2 of the PCM's user guide.

If a solenoid channel's output LED is illuminated red, then there should be Vsol measured across the red and black output of that channel's weidumuller pair.
Vsol will be approx battery voltage if the PCM jumper is in 12V mode.
Vsol will be 24V if jumper is in 24V mode or not present.
So use a voltmeter to measure the voltage leaving the PCM going into the solenoid harness. If the PCM is giving your 24V solenoid 24volts, then no amount of software is going to fix your problem, the issue is downstream and is likely the solenoid harness (happens to me once in a while) or just a bad solenoid.
