この発明は、主局に対して複数の従局が接続され、その
全ての従局の通信アドレスを主局で認識する通信アドレ
ス認識装置に関するものである。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a communication address recognition device in which a plurality of slave stations are connected to a master station, and the master station recognizes the communication addresses of all the slave stations. be.
一般に、主局に対して複数の従局が接続されている場合
、主局は受信したデータがどの従局からのデータである
かを認識するため、各従局の通信アドレスを認識してい
る必要がある。このため従来は主局においてオペレータ
が各従局の通信アドレスを一台ずつ手入力していた。Generally, when multiple slave stations are connected to a master station, the master station must recognize the communication address of each slave station in order to recognize which slave station received data is from. . For this reason, conventionally, an operator at the main station manually inputs the communication address of each slave station one by one.
しかしながらこの方法は非常に工数がかかり、また、キ
ー人力を間違えることもあシ、従局の数が多くなると限
られ要時間内に正確に設定することは非常に困難である
。However, this method requires a lot of man-hours, it is easy to make mistakes in key input, and when the number of slave stations increases, it is very difficult to set the settings accurately within the required time.
このような課題を解決するためにこの発明は、各従局が
特定の通信アドレスを送信できるようにしておき、その
信号を主局でｇｌ＆するようにしたものである。In order to solve these problems, the present invention allows each slave station to transmit a specific communication address, and the master station receives the signal.
主局から従局に対してアドレスを送信すべき準備のため
の信号を送信すると従局はその信号を受信して準備状態
になる。そこで操作者が従局を操作するとその従局特有
の通信アドレス信号が出力され、その通信アドレス信号
が主局で認識される。When the master station transmits a signal for preparation to transmit an address to the slave station, the slave station receives the signal and becomes ready. When an operator operates a slave station, a communication address signal unique to that slave station is output, and the communication address signal is recognized by the master station.

続されている。The figure is a block diagram showing one embodiment of the present invention. In the figure, 1 is a master station, and 2 is a slave station. The master station 1 is equipped with a preparation signal transmission means 11 and an address recognition means 12, and the slave station is equipped with a preparation signal detection means 21 and an address signal transmission means 22. A lamp 3 is connected to the preparation signal detection means 21, and a switch 4 is connected to the address signal transmission means 22.
このように構成され次装置の動作は次の通りである。先

信号を送信する。この信号は全従局に対して一斉に伝送
され、従局内の準備信号検出手段２１で検出されると、
それに接続されているランプ３を点滅させる。The operation of the device thus constructed is as follows. First, the preparation signal transmitting means 11 of the master station 1 transmits a preparation signal to all slave stations instructing them to prepare for transmitting an address signal. This signal is transmitted to all slave stations at the same time, and when detected by the preparation signal detection means 21 in the slave station,
The lamp 3 connected to it is made to blink.

灯させる。In this manner, when the slave station receives the preparation signal, the lamp 3 lights up, indicating that it is ready to transmit the communication address signal. When the operator of the slave station presses the switch 4, the address signal transmitting means 22 connected thereto transmits a communication address signal unique to the slave station. This address signal is transmitted to the main station and recognized by address signal recognition means 12. This recognition is performed by detecting and storing both the number of the equipment connected to the slave station and the communication address signal unique to the slave station. When recognition of a certain slave station is completed, the master station transmits a confirmation signal. This signal is transmitted from the preparation signal transmitting means 11 of the master station with the previously recognized communication address signal of the slave station added thereto. Therefore, the slave station that sent the communication address signal receives the confirmation signal using the a confirmation signal detection means 21, and turns off the lamp 3.
一つの従局のアドレス信号送信が済むと順次隣接する従
局のスイッチ４を押すことによって各従局のアドレス信
号が主局でＪＩＳ次認識され、記憶される。When the address signal of one slave station has been transmitted, the address signal of each slave station is recognized in JIS format by the master station by sequentially pressing the switch 4 of the adjacent slave station, and is stored.
このように順次、他の従局のスイッチを押すだけで主局
では全ての従局のアドレス信号を受信することができる
。In this way, the master station can receive the address signals of all the slave stations simply by sequentially pressing the switches of the other slave stations.

る。As explained above, the present invention allows the master station to recognize the address signal transmitted from the slave station, so there is no need to manually set the address signal as in the past, and the address can be set quickly. Moreover, it is easy to perform and has the effect that input errors do not occur. Furthermore, since it is possible to confirm that an address has not been set by lighting the lamp, there is no need to forget to set an address when a new module is inserted, and the module can function reliably.
