Abstract

PURPOSE: To evade the fixed 1:1 connection among plural CPUs and CRT devices serving as the man-machine interfaces of a system which performs the centralized supervisory and control of a plant, etc., via those CPUs and also to prevent increase of the CRT operating burden for every CPU. CONSTITUTION: The CPU 2 (2-1, 2-2) and the CRT devices 1 (1-1, 1-3) are connected together via a bus type LAN 11. When the CPU 2 transmit the state data collected from a plant onto the LAN 11, each of devices 1 receives the state data from the LAN 11 and converts them into the data on a screen display variable part. Then the device 1 takes out its own stored data on a screen display fixed part and combines together the data on both variable and fixed parts to display them on a screen. Thus any of CRT devices 1 can display the collected data on both CPUs on its screen, and the CPUs have not to produce the screen display data. This reduction of burden can eliminate the increase of burden of the LAN communication and the response speed is secured for the screen display.

In FIG. 3A, reference numeral 2 is a central processing unit (CPU) that controls the target device while collecting status data from the target device, and 1 is a keyboard or C (not shown).
It is a CRT device having a RT as a man-machine interface of a CPU. Further, FIG. 3B shows an example in which the CRT device is duplicated with 1 (1A, 1B). For example, the CRT device 1A is always on the operating side and 1B is on the standby side. Replaces the working side. The CRT device 1 is fixedly connected to the CPU 2 in FIG. 1A, and the CRT device 1 is connected to the CPU 2 in FIG.
The devices 1A and 1B are fixedly connected. FIG. 4 is a flowchart showing the division of screen display processing in the system of FIG. 3, in which 02 indicates processing on the CPU side and 01 indicates processing on the CRT device side. Reference numerals 221 to 223 indicate steps of the CPU side processing 02, and 211 indicates a CRT device side processing 01.
The steps are shown below.

Referring to FIG. 4, as shown in the CPU-side process 02, the CPU 2 first converts the state data collected from the plant into variable part display data as a variable part of the screen display data (221). Next, the CPU fetches fixed part display data which is stored in advance in the screen display data corresponding to the variable part display data and becomes a fixed part (for example, title, unit such as KV, A, ruled line, etc.) ( 22

Conventionally, as shown in FIG. 3, the CRT device 1 and the CPU 2 are fixedly connected to each other.
As shown in, the screen display data is created on the CPU 2 side and transmitted to the CRT device 1. However, in this method, since the CRT device and the CPU are fixedly connected, it is uneconomical to provide the CRT device 1 for each CPU 2 when a plurality of CPUs are installed and functions are distributed. It was

Further, in order to back up when the CRT device fails, it is necessary to provide two CRT devices for each CPU as shown in FIG. 3B. In addition, since all the screen display data is transmitted from the CPU to the CRT device, the CPU and the CRT device are required to reduce the overhead of the communication processing between them to secure the screen display speed of the CRT device.
Since the screen data that can be displayed is different for each CPU since it is connected in a one-to-one relationship, it is necessary to select the CRT device and perform the display operation in order to refer to all the screens, which is inconvenient for the operator to operate. Met.

According to the present invention, a plurality of CPUs that share the processing for controlling the target device while collecting state data from the target device and a CRT device as a man-machine interface for the CPUs are connected via a LAN. Since the connection is made, the data of a plurality of CPUs can be displayed on one CRT device, and the backup at the time of failure becomes possible.

Further, since the screen display data is created on the side of the CRT device, the communication load from the CPU to the CRT device is reduced. For example, the amount of data transmitted from the CPU to the CRT device is 10 4 bytes as in the conventional case. What used to be an order is reduced to an order of 10 2 bytes. This decrease in the CPU load also offsets the increase in the CPU's LAN protocol processing load and ensures the screen display speed of the CRT device.
