- the IF confirmation processing unit 13 uses the device side communication processing unit 83 to request IF information from the electric device 72a by a predetermined communication method. Specifically, the IF confirmation processing unit 13 requests IF information from the electrical device 72a at a transmission rate of 9600 bps. Since the ECHONET standard recommends transmission speeds of 9600 bps and 2400 bps, the adapter 71a and the electrical equipment 72a in this embodiment communicate at any transmission speed.
- the electrical equipment 72a that has received the IF information request responds to the IF information request when the communication method is the same. That is, when the transmission speed of the interface of the electrical device 72a is 9600 bps, the electrical device 72a responds to the IF information request and transmits the IF information to the adapter 71a.

If there are more than one transmission speed other than 9600bps and 2400bps, the IF confirmation processor 13 requests IF information by changing the transmission speed sequentially until there is a response from the electrical equipment 72a. You can configure it.
- the device-side communication processing unit 83 receives the IF information. If there is a response of IF information from the electrical equipment 72a, the IF confirmation processing unit 13 recognizes the communication method based on the IF information, and thereafter performs communication using that method. Here, if there is no response to the IF information request from the electric device 72a, the IF confirmation processing unit 13 cannot recognize the communication method with the electric device 72a, and there is an abnormality in the communication interface with the electric device 72a.

- the property for accepting construction request to be accepted is included, and the second object configuration information corresponding to the written object code is written when writing to the property for constructing the object code construction request is done by other terminal. Obtained from the original terminal. Therefore, it is possible to confirm whether other terminals can generate objects via the network by the existence of the property for accepting construction requests, and it is possible to reduce the repetition of unnecessary requests and reduce communication traffic. Can do.
- the second object configuration information acquired from the other terminal by the object configuration information acquisition means in the above communication device is divided into a plurality of units and sent to other terminals.
- the object configuration information acquisition means stores the second object configuration information stored in the other terminal based on the second object configuration information construction request received from the other terminal. It is preferable to specify and acquire each unit.
- the second object configuration information stored in the other terminal is divided for each unit into which the second object configuration information is stored based on the request for construction of the second object configuration information received by the other terminal. Therefore, the communication device can acquire only the necessary unit of information and acquire the terminal power of the source, and the amount of information exchanged at a time can be reduced.
- an abnormality notifying means for notifying other connected terminals of the abnormality.
- the communication control device, the communication control method, the communication control program, and the computer-readable recording medium on which the communication control program according to the present invention is recorded have an abnormality in the communication between the electric device and the communication device at the time of startup. Even if it is detected, the communication device can be started up alone, and information can be exchanged via the network, making maintenance easier when an error occurs, and maintaining communication with object information on the electrical equipment side. It is possible to realize a configuration that does not require the function of setting the device, which leads to the development of inexpensive electrical equipment as well as maintenance.
