Abstract
The present invention is applied to a distributed control system in which a plurality of control devices (a central control device, an individual control device, and the like) are connected via a network. For example, the central control device executes a start-up deadline determination processing for setting a start-up deadline in consideration of the performance of a device to be controlled, and communication processing for transmitting a packet including identification information of a command and information of the start-up deadline to the individual control device. For example, when receiving the packet transmitted from the central control device, the individual control device controls execution of the command on the device to be controlled on the basis of the start-up deadline included in the packet.
