摘要：In a distributed control system in which a plurality of nodes are connected to a
transmission line, each node controlling components connected to this node andtransmitting a message to other nodes, a message sent by each node includes at leasttwo message-sending condition-identifying portions, one of the condition-identifyingportions including data indicating a message-receiving node or non-designation of amessage-receiving node; and a comparison-selection circuit provided in each nodeincludes registration parts for registering data of message-receiving conditions, at leasttwo registration parts for comparing contents of the condition-identifying portion in thetaken-in message with the data of message-receiving conditions registered in theregistration parts, a received-message storing part for storing a message to be receivedin this node, a control part for determining whether or not the taken-in message is to bereceived in this node based on a result of comparison-processing performed in thecomparison and selection means and for transferring the taken-in message to thereceived-message storing part if it is determined that the taken-in message is received inthis node, otherwise, abandoning the taken-in message.
