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

A communication device, comprising:

• a storage configured to store a communication parameter corresponding to a regular command from a control device, the communication parameter corresponding to the communication device;
• a communication parameter responder configured to, upon receipt from the control device of a communication parameter request-command, send to the control device the communication parameter stored in the storage,
• the communication parameter request-command being any command other than the regular command;
• and
• a response time learner configured to learn a response time by measuring, each time the regular command is received from the control device, an amount of time that elapses from when the regular command is received until a response corresponding to the regular command is completed, and to save the response time, as a communication parameter, to the storage.

A communication adapter for connecting with an electrical device, the communication adapter comprising:

• a response time learner configured to learn a response time by measuring, each time a control instruction corresponding to a regular command is sent to the electrical device, an amount of time that elapses from when the control instruction is sent to the electrical device until a response to the control instruction returns from the electrical device, and to save the response time, as a communication parameter, to the storage;
• and
• a communication parameter responder configured to, upon receipt from a control device of a communication parameter request-command, send to the control device the communication parameter stored in the storage,
• wherein the communication parameter request-command is any command other than the regular command.

A communication parameter response method comprising:

• sending to a control device, by a communication device, a communication parameter stored in a storage upon receipt from the control device of a communication parameter request-command,
• the communication parameter corresponding to a regular command that is any command other than the communication parameter request-command, the communication parameter corresponding to the communication device;
• and
• learning, by the communication device, a response time by measuring, each time the regular command is received from the control device, an amount of time that elapses from when the regular command is received until a response corresponding to the regular command is completed, and saving, by the communication device, the response time as a communication parameter to the storage.

A non-transitory computer-readable recording medium storing a program configured to cause a communication device to function as:

• a communication parameter responder configured to, upon receipt from a control device of a communication parameter request-command, send to the control device a communication parameter stored in a storage,
• the communication parameter corresponding to a regular command that is any command other than the communication parameter request-command, the communication parameter corresponding to the communication device;
• and
• a response time learner configured to learn a response time by measuring, each time the regular command is received from the control device, an amount of time that elapses from when the regular command is received until a response corresponding to the regular command is completed, and to save the response time, as a communication parameter, to the storage.
