PROBLEM TO BE SOLVED: To synchronously operate a plurality of devices even in the case where data to be transmitted/received for synchronously operating the devices exceeds a capacity that is transmittable/receivable in one time of communication.SOLUTION: A control device 10 and one or more control target devices are connected over a network. The control device 10 comprises: storage means that stores information about a synchronization period that is a period for synchronization with a control target device, and a plurality of communication periods that are provided within one synchronization period; calculation means which calculates for each control target device a control command for commanding the control target device to synchronously operate; and communication control means which performs control so as to exchange the control command with each of the control target devices within the synchronization period on the basis of the information that is stored in the storage means, allocates each of the control commands corresponding to the control target devices to at least one of the plurality of communication periods provided within the synchronization period, and exchanges data including the allocated control command in each of the communication periods.SELECTED DRAWING: Figure 1 |
