ように構成したことを特徴とするデータ伝送装置。A plurality of stations are connected in series via a common transmission path, and frames containing addresses uniquely assigned to each station and a plurality of time slots for data to be transmitted from each station are transmitted and received. In a data transmission device that cyclically transmits data on the transmission path in units of 1 and 7, one of the stations transmits a plurality of signals in the frame so as to display the occurrence of an interrupt request from each of the other stations with a predetermined priority. Generates and sends an interrupt slot consisting of time slots, and responds only to the time slot corresponding to the highest priority at the current time from the interrupt slot of the received frame, and responds only to the time slot corresponding to the highest priority in the next frame. Time corresponding to priority
The station is configured to send out an interrupt acceptance indication l- only in the slot, and each of the other stations sets a predetermined title slot l- in the interrupt slot of the frame that receives the occurrence of an interrupt request. A data transmission device characterized in that the data transmission device is configured to determine that the interrupt has been accepted when the set of the time slot in the interrupt slot of the next frame is confirmed.
