In graphic display devices,
Various display screens are prepared for the convenience of man-machine communication, and a desired screen is called up and used according to the operator's needs.
In order to call up a display screen, a keyboard operation procedure is defined, and the operator operates the keyboard in accordance with the procedure to call up the desired display screen. In this case, for example, a function key for one-touch calling is provided so that a specific screen that is frequently used can be called up in a simple procedure. The function definition of the function key can be fixed from the beginning or
It allows for arbitrary changes during use.

Previously, function key definitions were changed using the maintenance utility, so during maintenance, the display device screen switches to the maintenance screen, and the previous online operation monitoring screen changes. The display screen could not be seen.

However, it is desirable that the display screen for online operation monitoring be displayed as constantly as possible so that the operator can always grasp the status of the processing target.

Conventionally, there have been display devices that have a function of dividing the display screen and displaying different information on each screen, but none of them have been able to define function keys while maintaining an online state.

SUMMARY OF THE INVENTION An object of the present invention is to provide a graphic display device that allows defining the function of a function key for calling a screen in an online state while keeping a screen for online operation monitoring displayed.

The present invention includes a graphic display device that displays a display screen for online operation monitoring, a keyboard that is provided with various keys including definition keys and function keys, and a graphic display that displays according to the operation of each key on the keyboard. and a control section for controlling the display of a device, and the control section is configured such that when the entire display screen for online operation monitoring is displayed on the graphic display device, the definition key is pressed. If operated, the main information on the screen will not become invisible while maintaining the online state according to the first program activated by operating the definition key. a first means for displaying the defined state of the function key in the space that has been shifted by a degree; and when the function key is operated while the screen of the graphic display is shifted as described above; According to the second program activated by the operation of the function key,
A second means of defining the calling function of the screen excluding the function key definition display among the screens displayed at that time to the function key that has just been operated, and the screen of the graphics display is shifted as described above. a third means for canceling the shift state according to the first program when the definition key is operated when the definition key is operated; and a graphic display for displaying a display screen for online operation monitoring. fourth means for displaying a screen defined for the function key on the graphic display according to the second program when the function key is operated during the entire display; This is a graphic display device characterized by having:

Hereinafter, the present invention will be explained in detail with reference to Examples. FIG. 1 shows a conceptual configuration of an embodiment of the present invention. In FIG. 1, 1 is a display device such as a CRT, 2 is a keyboard, and 3 is a control unit that controls the display on the display device in accordance with keyboard operations.
The keyboard 2 is equipped with various dedicated functions including alphanumeric keys, including a plurality of function keys 21 that can be defined for easy screen recall, and definitions for the function keys 21. A definition key 22 is provided for validating the binding. A plurality of function keys 21 are provided so that a plurality of screens can be designated on a one-to-one basis.

In order to make it possible to define a screen call by operating the function key 27 and definition key 22, the control section 3 is provided with functions that are activated in accordance with the operations of the respective keys. These functions are preferably realized by a program, and the second
It is like a flowchart in the figure. In FIG. 2, a is activated by operating the definition key 22, and b is activated by operating the function key 21.

The program that performs the processing shown in Figure 2 a is the first program, and the program that performs the processing shown in Figure 2 b is the second program.
The program shall be

Using such a program, the function key 21 is defined as follows. An explanatory diagram of the operation is shown in FIG.

First, a desired screen is called up by normal keyboard operations and displayed on the display 1, and then it is assumed that this screen can be called up with a single touch using any one of the function keys 21 in the future.
With this screen displayed, the define key 22 is pressed to start the program shown in FIG. 2a. Then, by the processing in step _A1 of the program, the display screen is shifted upward by a predetermined space, and the space S created by the shift is shifted upward.
The definitions already given to each of the function keys 21 are displayed in a list. The amount of shift is set to such an extent that the original main information is not obscured, and based on the information on the screen, the operator can perform monitoring operations on the monitored target in the same way as before the shift.

In this state, if you press any function key 21, for example ₂₁₁ , the program shown in FIG. The function of calling up the screens excluding the definition display section S of the function key 21 among the currently pressed screens is defined for the function key 211 that has just been pressed. At this time, the definition of the key that has just been pressed is added to the definition display area S of the function key 21.

Then, when the definition key 22 is pressed, the shift state of the screen is canceled by the processing in step _A3 of the program a, and the screen returns to the original screen display.

This completes the definition of the function key 211, and from now on the function key 21
Each time you press 1, the defined screen is called up with a single touch by the processing in step _A4 of the program b. Function keys 21 are similarly defined for the other screens, and thereafter each desired screen can be called up with a single touch using the defined keys.

FIG. 4 shows a configuration block diagram corresponding to the flowcharts of FIGS. 2 and 3.

In FIG. 4, the first means 31 presses the definition key 22 when the display screen for online operation monitoring is displayed on the entire screen on the graphic display 1.
is operated, the definition status of the function key 21 is displayed in the space where the display position of the screen currently being displayed is shifted to the extent that the main information on the screen is not obscured while maintaining the online state. . The first means 31 corresponds to the hardware part of the control section 3 that performs the process _A1 of FIG. _2A with the first program P1.

If the function key 21 is operated while the screen of the graphic display 1 is being shifted, the second means 32 is configured to display the screen excluding the definition display of the function key among the screens displayed at that time. Define the call function to the function key that was just operated. Second means 32
corresponds to the hardware part of the control unit 3 that performs the process _A2 of FIG. _2b with the second program P2.

The third means 33 cancels the shift state when the definition key 22 is operated while the screen of the graphic display 1 is being shifted. The third means 33 performs the processing of FIG. _2a using the first program P3.
This corresponds to the hardware part of the control unit 3 that performs _A3 .

The fourth means 34 is to press the function key 2 when the graphic display 1 is displaying a display screen for online operation monitoring on the entire screen.
When 1 is operated, the screen defined for that function key is displayed on the graphic display 1. The fourth means 34 corresponds to the hardware part of the control section 3 that performs the process _A4 of FIG. _2b with the second program P2.

According to the present invention, the display screen for online operation monitoring that was displayed before the definition is kept online even when the function keys are defined, and the main information on the screen does not disappear. information for defining the function key is displayed in the open area. This allows you to define function keys while staying online and grasping the status of the processing target on the online operation monitoring screen.
