しかし、通信アダプタ4が送信元アドレス(SA)=通信アダプタ(D)のデータを送信すると(s3)、リモコンはACKもNAKも返さず熱源機のみがACKを応答する(s4)。   However, when the communication adapter 4 transmits the data of the transmission source address (SA) = communication adapter (D) (s3), the remote controller returns neither ACK nor NAK, and only the heat source unit responds with ACK (s4).

(Embodiment 4)
In FIG. 3, when the heat source device 1 transmits data of the data type (PFC) = 0 (s5), the remote controller 3 and the communication adapter 4 recognize both as necessary data, receive the data, and respond with an ACK (s6). , S7).

しかし、熱源機1がデータ種別(PFC)=4のデータを送信すると(s8)、リモコン3は必要なデータと認識しないためACKもNAKも返さず、通信アダプタ4のみがACKを応答する(s9)。   However, when the heat source device 1 transmits data of the data type (PFC) = 4 (s8), the remote controller 3 does not recognize it as necessary data, so neither ACK nor NAK is returned, and only the communication adapter 4 responds with ACK (s9). ).

以上のように本実施の形態において、リモコンは受信データをデータ種別で判定し、熱源機と通信アダプタ間でのみ有効なデータは無視してNAK応答を行わないことにより、熱源機とリモコンのみのシステムと全く同じ条件で熱源機制御及び熱源機状態表示が可能となり、省施工で信頼性の高い通信システムを構築することができる。   As described above, in the present embodiment, the remote controller determines received data by data type, ignores data that is valid only between the heat source unit and the communication adapter, and does not perform a NAK response. Heat source machine control and heat source machine status display are possible under exactly the same conditions as the system, and a highly reliable communication system can be constructed with reduced construction.

(実施の形態5)
図4は本発明の第5、第6の実施の形態における通信データの流れ図であり、アドレス判定機能及びデータ種別判定機能の動作を示す。
(Embodiment 5)
FIG. 4 is a flow chart of communication data in the fifth and sixth embodiments of the present invention, and shows the operation of the address determination function and the data type determination function.

熱源機1は送信元アドレス(SA)=熱源機(F)のデータを送信すると(s10)、通信アダプタ4はデータを受信してACKを応答する(s11)。   When the heat source device 1 transmits the data of the transmission source address (SA) = the heat source device (F) (s10), the communication adapter 4 receives the data and responds with an ACK (s11).

しかし、リモコン3が送信元アドレス(SA)=リモコン(0)のデータを送信すると(s12)、通信アダプタ4はACKもNAKも返さず熱源機のみがACKを応答する(s13)。   However, when the remote controller 3 transmits the data of the transmission source address (SA) = remote controller (0) (s12), the communication adapter 4 returns neither ACK nor NAK, and only the heat source unit responds with ACK (s13).

以上のように本実施の形態においては、通信アダプタはリモコンからの送信と熱源機通信手段からの送信をアドレスデータで判定し、リモコンからの送信は無視してNAK応答を行わないことにより、リモコンの種類やリモコンでの運転オン、オフ、給湯温度変更等の操作に全く影響されることなく通信ネットワークから熱源機を監視、制御できるため信頼性の高い通信システムが実現できる。   As described above, in this embodiment, the communication adapter determines the transmission from the remote controller and the transmission from the heat source unit communication means by the address data, ignores the transmission from the remote controller, and does not perform the NAK response. A highly reliable communication system can be realized because the heat source device can be monitored and controlled from the communication network without being affected at all by the type of operation, operation on / off with the remote control, or by changing the hot water supply temperature.

(実施の形態6)
図4において熱源機1はデータ種別(PFC)=0のデータを送信すると(s14)、リモコン3及び通信アダプタ4はどちらも必要なデータと認識してデータを受信してACKを応答する(s15、s16)。
(Embodiment 6)

しかし、熱源機1がデータ種別(PFC)=7のデータを送信すると(s17)、通信アダプタ4は必要なデータと認識しないためACKもNAKも返さず、リモコン3のみがACKを応答する(s18)。   However, when the heat source device 1 transmits data of the data type (PFC) = 7 (s17), the communication adapter 4 does not recognize it as necessary data, so neither ACK nor NAK is returned, and only the remote controller 3 responds with ACK (s18). ).

以上のように本実施の形態において、通信アダプタは受信データをデータ種別で判定し、熱源機とリモコン間でのみ有効なデータは無視してNAK応答を行わないことにより、リモコンの表示情報や運転制御情報に全く影響されることなく通信ネットワークから熱源機を監視、制御できるため信頼性の高い通信システムが実現できる。   As described above, in this embodiment, the communication adapter determines received data by data type, ignores data that is valid only between the heat source unit and the remote controller, and does not perform a NAK response, thereby enabling display information and operation of the remote controller. Since the heat source device can be monitored and controlled from the communication network without being affected by the control information at all, a highly reliable communication system can be realized.

以上のように本発明にかかる通信装置は、ネットワーク用通信アダプタを熱源機の通信線上に設置することが可能となるので、浴室暖房機や床暖房等、外部端末機器と熱源機が通信を行うシステムに通信アダプタを追加する場合にも適用できる。   As described above, since the communication device according to the present invention can install the network communication adapter on the communication line of the heat source unit, the heat source unit communicates with an external terminal device such as a bathroom heater or a floor heater. It can also be applied when adding a communication adapter to the system.
