h1iopsusb123 has DAC error, requires a restart
It looks like h1iopsusb123 (SUSITM[X,Y],BS) had a timing error which resulted in a DACKILL, meaning all DAC outputs are 0.0V (and the 18bit-DAC AI chassis have disabled their outputs). A restart of all models on h1susb123 (/etc/startWorld.sh) is required to clear the problem.
Would the next person in the control room please call me on my cell and we can get this system running again.
