cRIO-9035 Disconnects When Running VI

[joelle5678]

I’m using a cRIO-9035 with several I/O modules, including NI-9472 (24 V digital outputs).
My LabVIEW project was working properly until I added new physical connections and the corresponding variables in the code.
Since then, the cRIO disconnects as soon as I run the VI.

Details:

• The POWER LED stays on and STATUS is off.

• All outputs are set to zero at startup.

• The connection drops exactly when the code begins to execute.

Switch to an older revision of your code when there was no error. (Do you already use a SCC tool? If not: implement one!)

Then do your changes again, but test them step by step…

You are using the word "connection" in two different contexts ("...added new physical connection..." vs "... the connection drops exactly ...").

Can you be a bit more specific?

What did you add?

What are "variables"?

What kind of "connection" drops?

I added new connections to my NI-9472 digital output module to open and close valves, and I also added thermocouples to my NI-9211 module.
Since then, when I load the code, I lose the communication between the cRIO and my LabVIEW project.

I can still see the cRIO in NI MAX, but I can no longer connect to it from my LabVIEW project.

After the problem appeared, I tried to connect the cRIO in a new blank LabVIEW project, but I couldn’t.
So, I restarted the cRIO, and it entered Safe Mode.
I saw that one possible solution was to uninstall and reinstall the LabVIEW software on the cRIO, so that’s what I’m doing right now.
