ABSTRACT:
A data frame which is transmitted from a transmitting station is provided with an individual response part (RS) having response bits (S1 to SN) corresponding to all stations on a network, so that the transmitting station initializes the individual response part (RS) in data transfer. Each receiving station outputs its own state to a prescribed position of the individual response part, and the transmitting station monitors the individual response part. Thus, it is possible to correctly confirm whether or not the data is normally transferred to those of the receiving stations which are to receive data.
