Denny called and reported getting cryo alarms on the solenoid at non-nonsensical temperatures. 

On the CSS screen all the temperatures were being reported as 555.55 K which Pablo reminded me is what the PLC inserts when it loses communications with the cRIO. 

When we went to the Hall to investigate we found that all the network jack LEDs were acting normal (however we couldn't ping the cRIO either from the EEL or locally from in Hall B) and that the USER1 LED wasn't blinking (normally blinks once a second as the heartbeart). 

With nothing in the error log, we simply rebooted the cRIO using the reset button on it. The temperatures are being readout correctly now. 

We will look into connecting the console out to one of the terminal servers so that way if there are any messages we can log them.
