する場合も中央処理装置側のソフトウェアも変更する必
要があった。In systems using conventional loop transmission paths, each terminal device is directly controlled by the central processing unit, resulting in low responsiveness.As the number of terminal devices increases, the load on the central processing unit increases, and the load on the transmission path also increases. increase Furthermore, when adding more terminals, it was also necessary to change the software on the central processing unit side.

末からの情報要求に対しても端末処理装置のみで情報提
供ができるため、拡張性、応答性を高メル方式テある。Conventionally, information was provided through complex information exchange between a central processing unit and a terminal processing unit, but the present invention provides information that is processed by the central processing unit and transmitted on a loop transmission path.
Since the terminal processing device independently determines and acquires information, the central processing unit does not need to be aware of the terminal processing device, so it can easily cope with the addition of terminal processing devices, and it can easily respond to information requests from terminals. Since information can be provided using only a terminal processing device, it is possible to provide high scalability and responsiveness using a high-performance method.
以下、本発明を図に従って詳細に説明する。 Hereinafter, the present invention will be explained in detail with reference to the drawings.

情報収集部、１２は情報蓄積部。In Fig. 1, 1 is a central processing unit, 2 is another system computer, 3 is a plant (equipment), 4 is a loop transmission line (broadcast, cast transmission line), 5-1゜5-2...5-n
is a terminal processing device, 6-1.6-2-6-n is a CRT device, and 7-1-7-n is a T/W device. In this configuration, the central processing unit processes information generated in the plant or other computers, adds an information identification code to the result (information), and outputs the result (information) onto the loop transmission line. The information structure at this time is shown in FIG. Each terminal processing device receives the information output on the transmission path. Next, one terminal processing device will be explained as an example. In FIG. 2, 11 is an information gathering section, and 12 is an information storage section.

理結果（情報）をループ伝送路へ出力するだけである。13 is an information editing department. The received information is collected by the information collection unit, which selects information necessary for the own terminal (CRT, T/W, etc.) by determining the information identification code, collects the necessary information from the received information, and stores it in the information storage unit. Accumulate in. The processing flow at this time is shown in FIG. Therefore, the central processing unit simply outputs the processing result (information) to the loop transmission path without being aware of the existence of the terminal processing unit.

The processing flow at this time is shown in FIG.

It is highly expandable because you only need to focus on the information, and therefore it can easily handle the addition of terminal processing equipment.Also, it is possible to respond to information requests from terminal equipment because it can be handled only by terminal processing. It is also highly sexual.
