The corner RGA (located on output arm between HAM4 and HAM5) lost connection to the control room computer and stopped collecting data around 6pm yesterday (2/6/25). The software gave an error stating "Driver Error: Run could not be stopped".

I could not ping the unit from the terminal, but Erik confirmed the port is still open on the network switch, so it seems to be an issue with the RGA electronics. Other RGAs connected to this computer can still be accessed.

I restarted the software and attempted to reconnect to the RGA, but no luck. I will have to wait until next Tuesday maintenance to troubleshoot. This unit had been collecting data for the past ~6 months without issue. I will perform a hardware reset at the next opportunity to try and bring the unit back online, otherwise we have a new PrismaPro we can replace this unit with during the next vent.
