Abstract

PURPOSE:To prevent deterioration in line operating efficiency by returning a reply frame selectively in response to the importance of transmission data. CONSTITUTION: TD1' in a transmission data 11 represents high importance and information 14 representing need of reply shows 'need of reply' is integrated in a transmission frame 10 as control information 12 together with sequence number information 13 'No.1'. The transmission frame 10 is received by a slave station equipment 2 via a transmission line 3 and the information 13 representing a sequence number of the transmission frame is returned while being integrated in a reply frame 20. Since 'TD2' in a transmission data 11 shows low importance and the information 14 representing the need of reply is integrated in the transmission frame 10 as 'no need of reply', the slave station equipment 2 completes the action on the transmission frame 10 without replying the reply frame 20.
