    "abstract": "Experience using hardware knobs as an operator interface for controlling\nequipment has varied considerably at different facilities. Reactions have\nranged from \"indispensable\" at some facilities, to \"virtually useless\" at\nothers. In this paper, we will attempt to outline some basic principles for\nsuccessful knob implementation. These principles derive from our own experience\nwith control knobs at the LANSCE Accelerator Complex and our recent effort to\nadapt our control knobs to EPICS. Topics to be covered include what the\noperator needs the knob to do, what the knob needs to know about the device it\nis controlling, and knob scaling issues. Advanced topics such as closed-loop,\nPID, and aggregate knobs are left as topics for future papers.",
