To standardize nodes before being connected to one and the same communication bus, the each node becoming possible to identify its individual information after being connected to one and the same communication bus and to simplify its configuration, regarding an individual information storage system, an individual information storage method, the nodes and an inspection device.

The individual information storage system causes a plurality of nodes to store their respective individual information, the plurality of nodes being connected to one and the same communication bus and performing control with the same content on control objects different from each other. While the plurality of nodes are connected to one and the same communication bus, a power controller capable of controlling power supply to each node is made to execute processing for sequentially supplying power to all the nodes one by one, a writer connected to the communication bus is made to transmit individual information to be written for each node to which the power is supplied to the communication bus in a process in which the power is sequentially supplied to all the nodes one by one, and then, the nodes to which the power is supplied are made to store the individual information transmitted from the writer to the communication bus into a storage device.
