Relay Outputs on Digital Side Car Not Working

[2B || !2B]

We're having the same issue, but we've found a temporary solution! The "Long" cRIO (8 slots) test board we have was having the issues with not running the relays. Our "Short" cRIO (4 slots) test board uses the relays without issues running the same code. (We're using java)

I don't have any clue why this happens, but my best guess at the moment is that the long cRIO is anti-relay...

Oh I forgot to follow up.

First of all, the "TEST" mode in the new driver station, is AWESOME! Kudos to the NI team for making that. I was pressuring our software team to make a custom dash board that has a maintenance screen that we can view and "force" I/O points, but the TEST mode does all this for the teams. Thank you for this.

Using test mode, we was able to "force" the relay output points on and off. This proved that everything work electrical. So it was a software problem.

After the software team reviews future, I was told the problem was the START VI was moved out of order. I believe it was before or after the references or something like that. Once they corrected that problem in the software, the compressor and all relays started working again.

They did confirm they had version 52.

The biggest take away was using the new TEST mode in the driver screen. That was a nice tool.

Thanks everyone for your input. Problem solved with us.

It was there last year too.

We were going to store our device references in global variables instead of the Refnum Registry, but since Test uses the registry we decided we had to use it too.
