摘要：
A multiplex transmission system includes a number of multiplex transmission devices connected to each other via a common transmission line for transmitting frames of data. Each frame of data includes a string of bits. The number of multiplex transmission devices includes a first multiplex transmission device having a first communication controller, the first communication controller transmitting a first frame of data at predetermined intervals of time while changing a predetermined bit of data in the first frame; and a second multiplex transmission device having a second communication controller, the second communication controller transmitting a second frame of data to the first multiplex transmission device in response to one of (i) a change in input data from an external equipment, and (ii) a change in the predetermined bit of the first frame when the first frame is received by the second multiplex transmission device from the first multiplex transmission device.
