| description | A control system in which a plurality of controllers and a redundant controller are connected to a common network, the plurality of controllers are divided into a highly available controller and other normal controllers, the redundant controller obtains context data of the highly available controller to hold the context data in a memory, holds programs of the plurality of controllers in a non-volatile memory, and holds the program of the highly available controller in the memory, and an arithmetic unit substitutes processing of the highly available controller by using the context data and the program of the highly available controller held in advance in the memory when a failure occurs in the highly available controller. |
