==Commands for control devices==
The DALI-2 standard <ref>[https://webstore.iec.ch/searchform&q=62386-103 IEC 62386-103]</ref> added standardisation of control devices. Control devices can include input devices such as daylight sensors, [[Passive infrared sensor|passive infrared]] room occupancy sensors, and manual lighting controls, or they can be application controllers that are the "brains" of the system - using information to make decisions and control the lights and other devices. Control devices can also combine the functionality of an application controller and an input device. Control devices use 24-bit forward frames, which are ignored by control gear, so up to 64 control devices may share the bus with up to 64 control gear.
