<p>PURPOSE:To provide multiplex transmission equipment in which the load of a data processing unit is lightened. CONSTITUTION:In this multiplex transmission equipment, the plural numbers of nodes constituted so as to be provided respectively with a communication control unit 101 to control communication and the data processing unit 102 to process data given and received through the communication are connected to a common communication line, and the communication control unit 101 is provided with a receiving buffer 203 which stores the data in a frame and repeats that data to the data processing unit 102, and circuits 201, 202 which judges whether or not the frame data DATA in the corresponding frame is valid on the basis of the flag data V/IV of the received frame, and stores only the data DATA of the frame shown to be valid by the result of that judgement in the receiving buffer 203.</p> |
