Our hall IOCs control the inputs and readbacks we get from our physical equipment in the hall. They are important technology that infrequently needs to be restarted due to hardware faults and the like.

IMPORTANT: SHIFTERS SHOULD NOT TRY TO RESET A FAULTED IOC THEMSELVES! Most IOCs don't have controls shifters can access and those that do should only be worked on by experts.
