えたことを特徴とするデータ通信システム。[Claims for Utility Model Registration] Consisting of a master station and a plurality of slave stations connected to the master station via a common transmission path, each slave station connects to the master station in response to polling from the master station. In a data communication system that sends packets to be transferred onto a common transmission path, when each slave station sends out multiple packets in response to polling from a master station, it indicates the number of transferred packets in at least a portion of the first packet. The master station includes means for including data, and the master station has means for delaying the next polling time for other slave stations by a time corresponding to the number of transfer packets included in the first packet received from the slave station. data communication system.
