PROBLEM TO BE SOLVED: To provide a data synchronization system allowing a plurality of route controllers to take over respective processes with each other, which has not been considered in a conventional technology.SOLUTION: A data synchronization system comprises a plurality of tracking controllers. When a first tracking controller detects abnormality of a second tracking controller, a plan data synchronization part of the first tracking controller copies plan data other than those used for the most recent control for the second tracking controller stored in an auxiliary storage of the first tracking controller to the main storage of the first tracking controller, and performs a synchronization with the plan data on the second tracking controller.SELECTED DRAWING: Figure 1 |
