Abstract

PURPOSE:To extend the data input time and to reduce the number of bits of one frame, by forming the dummy bit between the time slot for addressing of frame format on the common bus and the input/output data time slot. CONSTITUTION:The computer 1 and a plurality of process input/output terminal devices 3 in remote location are connected in loop with the frame format on the common bus. In this case, among the addressing time slot 7 to transmit the address for identification of the process input/output terminal device 3, output data from the computer 1 to each terminal device 3, and input/output data time slot 17 making the transmission of input data from each terminal device 3 to the computer 1 in the same frame, the dummy bit 19 in several bits is provided.
