Abstract: Reliability with which a control device at a transmission destination can receive data is improved. In a communication system in which a plurality of control devices for factory automation are connected to a network, a communication protocol among the control devices includes a publish/subscribe type. Each of the control devices includes: a data storage unit in which control data is stored; a publisher unit that transmits data including a state of the control device of the publisher unit itself to other control devices than the control device; and a subscriber unit that receives data from each of the other control devices. When a state of each of the other control devices that is received by the subscriber unit satisfies a reception allowing condition, the publisher unit transmits the control data of the control device of the publisher unit itself.

Abstract: A control device includes a cyclic communication part, a message communication part, and a communication management part. The cyclic communication part performs communication according to a preset cyclic period. The message communication part performs communication that need not conform to the cyclic period. The communication management part manages a communication schedule for the cyclic communication part and the message communication part. When it is detected that control data scheduled to be communicated is data for preferentially selecting communication in the cyclic communication part, the communication management part detects a communication state of the cyclic communication part. When cyclic communication is possible, the communication management part stores the control data in the cyclic communication part, and when cyclic communication is not possible, the communication management part stores the control data in the message communication part.
