at 22:15 UTS (15:15PDT) the h1iopoaf0 model detected both an ADC and a DAC error, resulting in zero'ed dac outputs. I restarted all the models within 10 minutes, which restored h1tcscs's control of the chiller setpoint DAC channels. The itmx laser temp had dropped from 23.25C to 21.5C in the 14 minutes which had elapsed, a rate of 0.14C/min
The IOPs STATE_WORD went from 512 (OVF) to 652 (ADC,DAC,DK,OVF)
We should schedule a complete power cycle of h1oaf0's IO Chassis to hard reset the 16bit DAC.
here is a one hour plot of itmx DAC drive and laser temp for this event.
