Abstract

PURPOSE:To attain the operation of release and the setting of a transmission suppressing state for each data transmitter by storing the priority in a data transmitter and a token frame relating to a data transmission processing respectively and controlling the operation of data transmission according to the quantity of both the priority. CONSTITUTION:A communication control section 221 compares transmission priority information changeable set from a computer (not shown) connected in advance by a data input/output lien 250 with priority information (PRI) 150 in the token frame 100 in advance, and when the former is larger than or equal to the latter, the data transmission is applied in response to a data transmission request. In such a case, the transmission processing of the data transmitter 200 is finished by sending the data to the data transmission line 240 again while the toke frame 100 is stored partly in the inside of the data transmitter 200. The communication control section 221 applies re-edit of the received token frame 100 by the data link control section 222 to send it to the data transmission line 240 through the loop connection part 230.
