A network control system with a simple configuration that can flexibly build an operational environment suited for particular functions and devices, gives a small load on transmission line and equipment, and can easily cope with new functions not presently conceivable. The network control system with a plurality of equipment interconnected through a transmission line controls at least one equipment by other equipment through the transmission line, and includes, as constituent elements of any of the equipment connected to the transmission line, a controller having a user interface and a device having a function list (8) representing its own functions. The device sends the function list (8) to the controller through the transmission line (1). By using the function list (8) thus received, the controller notifies the user of the device information and, according to an instruction from the user, controls the device by using the function list (8).
