Possible to read cRIO input voltage?

[adekruif]

Is it possible to get the input voltage to a cRIO in LabVIEW? I am working on setting up several cRIO's (9045) at a remote data collection site and it would be useful to know what the battery voltage to the cRIO is without needing an extra card. I've poked around on the RT palettes but haven't come across anything that looks like it would work.

Thanks for any help.

So you want to know the supply voltage of your cRIO instead of some typical "input voltage signal"?

AFAIK the cRIOs don't come with an internal supply voltage sensor/measurement, you have to provide your own measurement channel with an AI module…

Yes, I am trying to read the supply voltage to the cRIO.

I was afraid there wasn't any way to read it in LabVIEW but was hoping I hadn't come across the way to do it.
