A control system, apparatus, and method are provided. In the control system, plural apparatuses in time synchronization with one another are connected to a network, and the network transfers a frame periodically exchanged by the apparatuses. The apparatuses include a control device and an apparatus controlled by the control device. Each apparatus in the control system is connected over the network, to a first apparatus that transmits a frame that arrives at each of the apparatuses and a second apparatus that receives a frame transmitted from each of the apparatuses. Each apparatus includes information on a frame transfer path and transfer timing based on a synchronous time. When a frame does not arrive at defined time through the transfer path and when a condition associated with a cycle is satisfied, one or more of the apparatuses is configured to transmit a resend request through the transfer path.
A control system in which a plurality of apparatuses in time synchronization with one another are connected to a network, wherein
