Abstract
A control device searches for a device to which a global identification (ID) including a manufacturer ID and a device ID is assigned in advance, by searching for the global ID. The manufacturer ID is set for each manufacturer using m bits, and the device ID is uniquely set by each manufacturer using n bits. M and n each are a natural number. The control device includes: a storage storing the manufacturer ID; an inquirer designating a possible range of the global ID at a time when m bits indicated by the manufacturer ID stored in the storage are fixed, and making, to devices connected to the control device, an inquiry about whether a global ID assigned to the device is in the possible range; and a receiver receiving, from the devices, a response to the inquiry, the response indicating that the global ID is in the possible range.
