Volts in Driver Station reads 00.00

Technical NI LabVIEW

My team is having a strange problem. When we turn on our robot, we can’t see the correct voltage on the driver station. All it reads is 00.00 all the time. We have triple-checked that the jumper is the the outer two pins on the analog module and the module is the correct one (we used it on last years competition robot which showed the correct voltage). We have re coded our code twice, still the same result. We are using a 4-slot cRIO and have re-imaged that several times.

Anyone have any ideas or having this issue?

Is your dashboard set to remote or local in the driver station?

It’s set to local

Code and settings have nothing to do with it. It’s a service that’s provided by the FRC system.

Have you wired 12v power from the Power Distribution Panel directly to the Analog Breakout?
Is the Breakout longer than the similar Solenoid Breakout?

Do you mean the blue module or the breakout board? We have the 12V to the breakout board (white connector) if that’s what you mean…

I’m not sure what you mean by blue module, but it might be the Power Distribution Panel (the one with all the circuit breakers). :slight_smile:
You guessed right about my meaning though, the Analog Breakout is receiving 12v if the green status light on it is glowing green.

The only pieces that affect the voltage display on the Driver Station are mostly the electrical wiring and connections:

  • The connector in the bottom of the first slot on the cRIO (no bent/broken pins)
  • The Analog module installed in the first cRIO slot (no green LEDs on it like the Solenoid cRIO Module)
  • The Analog Breakout
  • The jumper on the outer two pins of the Analog Breakout
  • The 12v power wired via a white wago to the Power Distribution (green status on the Analog Breakout)
  • A circuit breaker for the circuit on the Power Distribution Panel

*]In code if you opened Analog 8 (Analog 8 should be left alone)

Thanks! I’ll check with our electrical team about these and get back tomorrow evening when we check it.

OK, so we fixed the problem. Apparently, the electrical team crossed the wires. Thanks for the help!
