UDP module throws critical error 20

Go to solution

Does anyone know what the error code 20 means? I looked at possible UDP error codes but it does not seem to be one. It causes the engine to transition to safe state. Even telling the engine to recover critical errors does not help. Network seems to be fine... any ideas?

I think I know what it is. I had an HMI talking to the cRIO via UDP, and the configuration file for the HMI file had not been updated. So there was a mismatch between data expected by the cRIO and what it received. So error 20 is the result of that
