Abstract
A method of multiplex transmission for effecting multiplex transmission among a plurality of multiplex nodes is disclosed. The multiplex nodes are connected to a transmission path in which each multiplex node has its own node connection information for controlling its signal transmission and reception, and is capable of controlling and correcting the node connection information such that when a first multiplex node finds that a second multiplex node is in a normal state according to the node connection information of the first multiplex node and the remaining multiplex nodes find that the second multiplex node is in an abnormal state according to the node connection information of the remaining multiplex nodes, and when it is recognized that there is inconsistency in the node connection information between the first multiplex node and the remaining multiplex nodes and that a state of the second multiplex node should be recognized as normal, the remaining multiplex nodes transmit a request signal, which request the second multiplex node to transmit a return-to-normal signal which represents that the second multiplex node as returned to normal. Wherein the remaining multiplex nodes transmit the request signal at a predetermined time after the recognition of the inconsistency if they have received no request signal transmitted from any other multiplex node by that time, the predetermined time differing from node to node, the remaining multiplex nodes transmit no request signal if they have received a request signal transmitted from any other multiplex node.
