<p>PURPOSE:To allow the transmitter to continue the communication even when a fault such as a broken line or a short-circuit or the like in a multiplex transmission line or a fault of a communication chip arranged to each node takes place. CONSTITUTION:This transmitter is provided with two systems of multiplex transmission lines as a high speed multiplex transmission line 1 and a low speed multiplex transmission line 2. A node B20 being a control node having an actuator 25 is provided with an active high speed communication chip 21 and a standby low speed communication chip 22. A TMS node 40 monitoring the two systems of the multiplex transmission lines 1, 2 gives a command to the node B20 through the low speed multiplex transmission line 2 to implement communication by the standby communication chip 22 when a fault of the active communication chip 21 is detected in the node B20 and relays the read data of a sensor 13 sent by a node A10 to the high multiplex transmission line 1 to the node B20 by using the high speed communication chip 41 and the low speed communication chip 42.</p> |
