A device control apparatus periodically transmits a status confirmation signal to a control source device described in a cooperation control table and receives a response signal with respect to the status confirmation signal. Device control apparatus determines whether or not a status included in the response signal matches a status described in the cooperation control table. If they match, a control destination device, an operation and a control command corresponding to the operation are specified using the cooperation control table. A configuration for transmitting a control command with respect to the control destination device is provided. Therefore, even in a case where a communication protocol and the control command are different from one another in makers of devices, it is possible to realize cooperation control.
