この発明は複数個の端末装置へのアドレス情報を設定す
る端末アドレス設定方式に関するものである。Detailed Description of the Invention 3. Detailed Description of the Invention [Field of Industrial Application] This invention relates to a terminal address setting method for setting address information to a plurality of terminal devices.
従来、この種の端末装置へのアドレス設定は各端末装置

い紘端末に接続された外部回路からのコマンド入力で行
なっていた。Conventionally, address setting for this type of terminal device has been done using a dip switch attached to each terminal device, or by inputting a command from an external circuit connected to the terminal.

り、端末装置が大形化するなどの問題点がある。In the conventional terminal address setting method described above, each terminal device must directly set an address with an individual switch or set a command address. However, when setting is done using a dip switch, if an attempt is made to increase the address value, the number of terminals set using the switch increases, which hinders the integration of terminals. On the other hand, when setting is performed using commands from an external circuit, an external circuit for inputting commands is required, which poses problems such as increasing the size of the terminal device.

It is.

Means for outputting an address setting command having address information to be set in a terminal device; Means for determining whether or not an address has been normally set to the first to nth terminal devices connected in a loop; and transmitting and receiving data. The main devices 2a to 2n are the first to nth terminal devices, and are connected in series to the communication lines 3a to 3, and then connected via the communication circuit 4 and the main device 1. It is formed into a loop shape.
次に、上記構成による端末アドレス設定方式の動作につ

マンドに指定され、主装置１および各端末装置２ａ〜２
ｎが抽出可能な値であればよいことはもちろんである。Next, the operation of the terminal address setting method with the above configuration will be explained. First, the main device 1 sends an address setting command a having an address to be set to the terminal device 2a, for example, "abc" as the address information, through the communication line 3a.The terminal device 21 receives this address setting command α, and the address setting command "a" In this case, the terminal device 2a extracts the address information @“aba” that the terminal device 2a received, and extracts the address of its own terminal, e.g., a
b'·10m is set as the address information of the address setting command β. Here, the address increment value m can be any integer greater than or equal to 1, but m is for each terminal device (
Terminal devices 2a to 2n) are constant, and the increased value is the main device 1.
or is specified in the address setting command, and is a value that is registered in the main device 1 and each terminal device 2a to 2.
Of course, n may be any value that can be extracted.
そして、アドレス設定コマンドβを受信した端末装置２

Similarly, b stores the address "aba+m" as its own terminal address, and sends an address setting command r with "aba+2m" as address information to the next terminal device 2c.

とになる。By repeating this process in sequence, the terminal device 2n
K is abe-)(n-1)Xm address is set,
An address setting command π having &b.1IXm as address information is sent from the terminal device 2n to the main device 1 via the communication line 4. As a result, the main device 1, which has received the address setting command π, calculates the number of terminals registered in itself n, the address increment m between the terminals, the address information abe of the nine address setting commands a sent by the main device, and From the address information abc + nxm of the address setting command mushroom, it is determined whether the address is correctly set for all terminal devices and whether the address is mourned or not. In other words, the number of terminals x the address increase (ab 10 m This means that addresses have been correctly set for all terminals.
このようにして、各端末装置２＆〜２ｎに正常にアドレ

ｂへ送出する。For example, when sending data from the main device 1 to the terminal device 2b,
The main device 1 sends a data transmission command I having address information "ab@+m" to the terminal device 2a via the communication line 3&. Then, this terminal device 2a checks the address of this command, confirms that the data is not for its own terminal, and then passes this command as is to the terminal device 2a.
Send to b.

ことができる。Therefore, since the address of Jin's command matches its own terminal address, the terminal device 2b accepts this command. In this way, data can be transmitted from the main device 1 to the terminal device 2b. Similarly below,
Data can be transmitted from one device [1 to each terminal device 2&~2n.

で構成することができゐ表どの効果がある。As explained in detail above, according to the terminal address setting method according to the present invention, addresses are sequentially set in each terminal device according to the address setting command sent from the main device and the address setting command created by each terminal device. This eliminates the need to directly set an address on each terminal device, and it can be used in automatic processing or in places where it is difficult to directly touch the inside of the terminal device, such as high places, underground, narrow spaces, and closed places. A terminal device can be set up. In addition, since the commands used for address setting share the line used for data communication, there is no need for external circuits for address setting or interfaces with external circuits, and the terminal device can be made smaller. Since the terminal device can perform address setting and data transmission/reception using the same procedure, the address setting circuit and data transmission/reception circuit of each terminal device can be constructed from the same circuit, which has the following effects.
