as part of the SR3 investigation, we restarted the h1iopsush56 model to re-calibrate the 18bit DACs. The procedure was: stop user models, stop IOP model, start IOP model, check the status of the 18bit DAC autocal, clear the SWWD DACKILLs to stop the SEI SWWD countdown, start the user models one at a time.
Looking at the AUTOCAL history, this restart and the previous 3 restarts since the last reboot have all successfully calibrated all 5 DAC cards in the correct amount of time.
