The DAC enable status of the h1iopseih45 model went bad at 14:16:44 PDT on Sept. 11.  This required all models to be killed, then the IOP model to be restarted, followed by starting all the user models again.  At the time the DAC enable went bad, the IOP state word also reported a FE, Timing, and ADC error, which were cleared leaving the DAC enable error which requires a model restart to clear.
