Abrégé

According to the present invention, when there is a change in a network configuration, timers of a changed network configuration are synchronized with a timer having high accuracy among the timers. This control system has a network configuration in which one or more control devices each for controlling a target can be communicably connected to a network, and each of the one or more control devices has: a timer for managing time with accuracy; a communication means for transmitting a control command to a target corresponding to said control device on the basis of the time managed by the timer; and a timer synchronization means that, when the network configuration is changed, time-synchronizes, among timers of each control device of a changed network configuration, timers with another timer having higher accuracy than the timers.
