Abstract

A multiplex transmission system includes a multiplex transmission network through which normality and abnormality processing control specification information (PCSI) for loads are transmitted. A master load control unit (LCU) is connected to the multiplex transmission network. The master load control unit can multiplex the abnormality PCSi for a load as a main operation. A slave load control unit (LCU) is connected to the multiplex transmission network. The slave load control unit can multiplex the abnormality PCSI as a slave operation between itself and the main LCU. A storage device is mounted in the master and slave LCUs. The storage device can update and hold the information and read it at any time. In this multiplex transmission system, multiplexing abnormality can be detected and abnormality processing in the LCU in an abnormal state is controlled to urge its recovery of the LCU to a normal state.
