Abstract
A control apparatus includes a synchronization state transmission/reception unit configured to transmit and receive a synchronization state to and from another control apparatus via a network, and a state data transmission/reception unit configured to transmit and receive state data to and from the another control apparatus via the network. Thus, the control apparatus can grasp the synchronization state of the another control apparatus. Further, even when the control apparatus is restarted due to a failure, the control apparatus receives state data from another control apparatus that has been synchronized with the control apparatus and is in operation so that the control apparatus can recover without stopping the entire system.
