Usually, when creating a display screen, the layout on the screen is often determined first, and the function of each area is often determined or changed later. However, in the conventional display device program creation device,
When the display screen shown in FIG. 13 is created, the display-only area and the setting display area must be separately created, and therefore each area should be a display-only area before arranging each area on the screen. It is necessary to decide whether to use the setting display area. Therefore, it is not possible to take the work procedure of deciding whether each area should be a display-only area or a setting display area after arranging each area on the screen.

When changing the display-only area once created on the screen to the setting display area, the setting display area must be newly created after deleting the display-only area.

As described above, there is a problem that flexibility and flexibility in the procedure for creating the display screen are small, and the labor and time for creating the display program are large. It is an object of the present invention to provide a display device and a program creation device thereof, which can arrange a data setting region on a screen and then arrange a data setting region on the screen.

Is displayed. As shown in FIG. 12D, at the time of data setting, the second screen B is displayed so as to overlap the first screen A1. As a result, the frames 201, 202, 203 are arranged on the display areas 101, 102, 103 arranged on the first screen A1, respectively, and the numeric keypad 7 is used.
01 is displayed.

In this way, the frames 201, 202, 2
The second screen B on which 03 and the numeric keypad 701 are arranged can be commonly used for the plurality of first screens A1 to An. Therefore, the amount of screen drawing data and the number of man-hours for drawing and editing can be reduced.

In the above-mentioned embodiment, the frame is selected using the selection key of the ten-key on the screen. However, if the function of the touch switch is added to the frame arranged on the screen, the frame is selected. The frame can be selected by pressing.

According to the first and second aspects of the invention, when the data setting area is arranged at an arbitrary position on the screen independently of the data displaying area and the data displaying area exists in the data setting area. Since data can be set in the data storage unit of the external device via the data display area, it exists at an arbitrary position on the screen after the data display area is arranged on the screen when the display screen is created. The data display area can be changed to an area for displaying data and setting data. Therefore, flexibility and flexibility in the procedure for creating the display screen are increased.

In particular, according to the second invention, since the data setting area can be commonly used for a plurality of screens, the storage capacity of the second storage means for storing the setting information can be reduced. Becomes

According to the third and fourth aspects, the data display area can be arranged on the screen since the data setting area can be arranged at an arbitrary position on the screen after the data display area is arranged on the screen. After that, it becomes possible to change any area on the screen to an area for data display and data setting. Therefore, the flexibility and flexibility in the procedure for creating the display program are increased, and the labor and time for creating the display program are reduced.

In particular, according to the fourth aspect, since the data setting area can be commonly used for a plurality of screens, it is possible to reduce the data amount of the created screen and the man-hour for creating the screen.
