ABSTRACT:
In a ring network system formed by a plurality of nodes connected to one another through a ring-shaped path, each of the nodes collects all of node information signals representative of states of the nodes and memorizes the node information signals in a node information signal memory included in each node. The node information signal is periodically transmitted to each node from an adjacent one or ones of the nodes through the ring-shaped path and is renewed from time to time. Such collection of all of the node information signal in each node makes it easy to check an alarm by a superintendent.
