Document Type and Number:
Japanese Patent JP3444146
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide communication control equipment with which idle time executing no transmission from each slave station to a master station can be shortened in order to provide maximum transmission efficiency within the limited band width of a network connecting the master station and the plural slave stations.
SOLUTION: Concerning a system with which a batch transmission frame is transmitted from the master station to the plural slave stations and individual response frames are transmitted from the respective slave stations to the master station, the batch transmission frame is transmitted from the master station while previously containing the transmission order designation of slave stations. When each slave station is to respond to the master station, based on the transmission order designation sent from the master station, the response frame of a slave station preceding to the present station is successively and continuously transmitted to the master station each time its transmission is completed.
