Solenoid Issue

The solenoid breakout only has one green LED, and that indicates only that it is receiving power. You need to look at the array of eight green LEDs on the NI 9472 Digital Sourcing Module installed in slot 3 of the cRIO. They are labeled 0-7, corresponding to solenoid outputs 1-8.

The Solenoid breakout is the blue board plugged into the NI 9472?

Yes, the breakout is the smallish circuit board that plugs into the NI 9472 module. Like Alan said, there is one led on the breakout to indicate it has power, and then there are 8 leds on the NI 9472 module itself. If you cant see a reaction from any of the 8 leds, then try assigning an empty solonoid channel, lets say chanel 8. So in begin all you need to do is open the solenoid and assign it to channel 8, and then do a solenoid set with a constant of on wired to the input. Now when run the code and enable your robot the led indicator for channel 8 will go on and never turn off. So hopefully that will help you find the leds. Your code seemed as if it should do what you wanted to, once you find the led's and see if they are actuating you will know if the code is responding correctly. if the leds actuate but the valve does not bu sure to check the wiring and voltage requirements of the solenoid valve.

I changed it to a victor plugged into relay. Is the relay incorrect? My teacher is saying to plug it into the Digital I/O but I dont know how to work that in the programming.

The solenoid is hooked into the victor on the M+ and M- side, then into 30A on the power board with the 20A plug.

I also have it all RELAY on the programming.

Remove the Victor immediately. You're going to burn something up.

Solenoids do not connect to Speed Controllers. They connect either to the Solenoid Breakout on the DIO module, or to a Spike controlled by a Relay output on the Digital Sidecar.

Is your solenoid a 12V part or a 24V part?

Ok we found a spike! Turns out webster thomas gave us one. I plugged it into RELAY 3. should it all work right now? People are still cutting and tightening bolts and fileing. so i have to wait a few minutes.

[chall3613]

It didn't work. Am i allowed to keep just the solenoid and the spike out of the bag to work on it?
