Communication device, communication adaptor, communication system, communication parameter response method, and program

Communication parameters are stored in a data storage unit (21) of a communication device (2). A communication parameter response unit (220) possessed by a control unit (22), when having received from a control apparatus via a communication unit (20) a communication parameter request command indicating a request for communication parameters, reads and acquires the communication parameters stored in the data storage unit (21). The communication parameter response unit (220) generates a response command storing the acquired communication parameters and transmits the generated response command to the control apparatus via the communication unit (20).
