PURPOSE:To obtain a multiplex transmission equipment by which the maximum value of a message latent time is decided designingly in a nondestructive arbitration type line contention system multiplex transmission system. CONSTITUTION:The transmission equipment is provided with a storage circuit 16 storing the priority corresponding part of a message whose priority in storing in a current multiplex transmission line is higher when a specific transmission node is failed in the line contention and the priority of its own message is dynamically revised to be higher priority by referencing to the stored priority. Moreover, the priority part and the destination designation part of the message are stored to separate locations of the message. Since the transmission time of the message is confirmed in such a manner, the application of the transmitter to a coordinate controller for automobiles is attained. |
