PURPOSE:To prevent the extreme reduction in throughput in multiple address communication by allowing a sender station to send the same multiple address communication signal to all reception stations continuously for plural number of times. CONSTITUTION:Each of the same multiple address communication data A, B is sent consecutively for four-number of times. Thus, even if a reception defect NG takes place twice consecutively in a reception station #3 shown in figure (d), the next 3rd multiple address communication signal is received normally and no problem is caused. Since the multiple address communication signal is sent unidirectionally from the sender station for plural number of times, even if a temporary reception error occurs, the reciprocal communication time to reply the communication is not required. Thus, the event reducing the throughput extremely is minimized. |
