If we plan to use the new LIGO 28AO32 DAC to drive ETMX L1,L2,L3 for a while, we should add this new DAC to the IOP model's software watchdog (SWWD) DACKILL list.
Currently if the h1iopsusex SWWD is triggered for 15mins, it will DACKILL the 18bit and 20bit DACs, but not the 28bit.
This requires are restart of all the models on h1susex, but no DAQ restart is required.
Yes, I think that we can squeeze this in as a target-of-opportunity, if the IFO is unlocked during business hours sometime. We have enough other watchdogs (including the lockloss triggers to stop outputs even if guardian is not working), that I think it should be okay to not break the lock for this, or wake someone up in the middle of the night to do the restart.
EDIT: Dave just noted to me in an email that it can also wait until next Tuesday, if we don't get it in before then.
