<p>PROBLEM TO BE SOLVED: To provide a method and a device for identifying dangerous state data in a system having a redundant component. SOLUTION: The method contains a step where respective nodes show the system by a plurality of nodes which have the number of routes, which shows the number of routes introduced to the nodes, and which show components and by a plurality of routes showing a communication route between the components, a step reducing the number of routes by one on the respective nodes for respective faults in the route introduced to the node, a step reducing the number of routes by one on the respective nodes of all the routes introduced from the respective nodes having the number '0' of routes, a step reducing the number of routes by one on the respective nodes on all the routes introduced from the node where the fault occurs and a step for indicating the graphical drawing of the nodes and the routes to a user.</p> |
