BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for controlling the output of a hard copy of a screen in a computer processing system mainly used for process control.

[0002]

2. Description of the Related Art Conventionally, in a computer processing system used for process control, a computer processing system is often constructed by using an apparatus as shown in FIG. In the processing system of FIG. 3, a display control device 32 different from the central processing unit 31 is installed in order to improve the display speed of the screen, and the screen display in the display control device 32 is performed from the storage device 33 in the central processing unit 31. The screen data stored in the memory 34 is used to send the screen data to the display device 35 to display the screen.
Further, when a hard copy output command is given from the central processing unit 36 in the central processing unit 31 to the display control unit 32 through the input / output channel 37, the hard copy interface unit 38 passes through the hard copy unit 39
The hard copy output request is sent to the hard copy device 39, and the hard copy device 39 outputs the hard copy using the display data of the screen stored in the screen display memory 34.

FIG. 4 shows an example of hard copy output processing when a conventional apparatus is used. In FIG. 4 and FIG. 3, first, a process 41 for converting the source data for screen display into object data for screen display convenient for screen display at the time of system generation and registering it in the storage device 33 is performed. Next, when the system is used for operation and a screen display request 42 is issued to the display device, the storage device 3
A process 43 of storing the object display data for screen display from the third display control device 32 is executed. Subsequently, when the system operator issues a hard copy output request 44, a process 45 for instructing the hard copy device to start outputting the hard copy is executed, and the screen data in the screen display memory 34 is captured by the hard copy device. And a hard copy is output.

Here, as shown in FIG. 5, the screen configuration of a computer system used for process control is often composed of a main screen display area 51 and a sub-screen display area 52. . Here, the display area 5 of the main screen
1 is an area for displaying a list or graph of the monitored and controlled devices of the computer, the graphic display of the controlled devices and plants, the monitoring of these monitored and controlled devices by the computer, and operator results. Further, the display area 52 of the sub-screen is used as an area for displaying an instruction item for the operator to give an instruction to these monitored objects, controlled objects and the computer itself through the computer. FIG. 5 shows a display example of a screen used for monitoring and controlling the power system. In FIG. 5, the display area of the main screen is the area indicated by symbol 51, and the display area of the sub-screen is the area indicated by symbol 52.

The system operator can obtain a hard copy of the displayed screen by giving a request for outputting the hard copy of the screen to the computer system.
However, what the system operator needs is information about the screen displayed in the display area of the main screen, and does not require information about the screen displayed in the display area of the sub-screen. Also, in the display area of the main screen, the list or graph in which the information required by the operator is displayed is often limited.

That is, according to the conventional method, the hard copy of the obtained screen also outputs a portion not required by the operator. Therefore, in order to obtain a hard copy of only the necessary information, the method shown in FIG.
A hard copy was output using the method shown in. Figure 6
In FIG. 3 and FIG. 3, as shown in FIG. 6, the output range and the enlargement ratio of the hard copy are registered in the storage device 33 by the process 61 together with the object data of the screen when the system is generated, and the screen is displayed by the operator when the system is operated. Process 6 for storing the object data of the screen from the storage device 33 to the screen display memory 34 when the display request 62 of 6 is generated.
3 is executed and the screen is displayed on the display device 35, and if a hard copy output request 64 is generated by the system operator, the screen object data is output from the storage device 33 to the screen display memory 34 as a hard copy. A process 65 for converting and storing based on the range and the enlargement ratio is executed to re-display on the display device 35 as a hard copy output image, and then a process 66 for making a hard copy output request to the hard copy device is executed. It was outputting a hard copy of the screen.

[0007]

When a hard copy of a screen within a specific range required by the operator is obtained by using the processing method shown in FIG. 6, a process 65 for once redisplaying the screen is performed. Since it is executed, it takes time for the process to redisplay this screen, and it is troublesome for the operator to redisplay the screen.
