Patent ID: 8775690

Claim:
A control apparatus comprising: a first processor that is operative to perform outputting first data including control data using a first communication method; a first input/output interface that receives the first data using the first communication method; a second input/output interface that receives and outputs data using the first communication method; a third input/output interface that receives and outputs data using a second communication method, in which transmission speed is lower than transmission speed in the first communication method; and a second processor that is operable to perform controlling the second input/output interface in such a way that the second input/output interface outputs third data, which is obtained by replacing the control data included in the first data received by the first input/output interface with second data received by the third input/output interface, to a control target apparatus, controlling the control target apparatus in such a way that the control target apparatus outputs the third data received from the second input/output interface, and controlling the third input/output interface in such a way that the third input/output interface outputs response data in response to the third data received from the control target apparatus, wherein the control data is a tag of a response packet, and the replaced tag is used to indicate whether the third data is a response to a write request packet, a read request packet, a control packet, a replaced read request packet, or a replaced write request packet.
