Abstract
A data management method controls the transfer of data in a communication system in which a plurality of stations are coupled to a same data transmission path. Each of the stations operates in one of a master mode and a slave mode. In the master mode, a station transmits a frame of data on the data transmission path, the frame of data including an address designating a station which is to operate in the slave mode and a command designating functions to be carried out by the station designated to operate in the slave mode. In the slave mode, a station receives the frame of data transmitted by the station operating in the master mode, and carries out data processing in accordance with the command contained in the thus received frame of data.
