Abstract

A multiplex communications system includes a plurality of master-slave sub-systems which include master nodes ( ) connected to a multiplex communications line (BL) and slave nodes ( ) connected to the same. Each master node transmits a signal to the slave node of the same sub-system at a first given cycle, and in response the slave node transmits a signal, thereby establishing communication between the master node and the slave node. If periodic transmission of a signal at the first given cycle is not correctly carried out, the master node, which correctly performs periodic transmission of a signal, periodically transmits a signal to both the slave nodes at a second given cycle which is slightly longer than the first given cycle. If the specific two slave nodes of the master-slave sub-system does not carry out periodic transmission of a signal at the second given cycle, the master node periodically transmits a signal between the two specific slave nodes at a third given cycle, which is slightly longer than the second given cycle.
