Hereinafter, the processing procedure according to the present invention will be described with reference to this flowchart. First, it is searched whether or not the numerical data indicated by the numerical data designation command CNUM sent from the input interpreting unit 2 'is in the screen layout data DLYT sent from the screen layout storing unit 4'. The numerical data referred to here is data (layout number or the like) for specifying the screen layout. If there is the corresponding numerical data, the process from step S302 is executed (step S301). Next, coordinate values of a screen layout corresponding to the corresponding numerical data are obtained from the screen layout data DLYT, and display update prohibited area data DARA is created based on the coordinate values (step S302). Next, the subscript i for specifying the individual pixel data DDOT constituting the image data DDRW is initialized to 0 (step S303).

Next, it is checked whether or not the processing has been completed for all the pixel data DDOT (i). If the processing has not been completed, the processing from the next step S305 is executed (step S304). First, the coordinates at which the pixel data DDOT (i) is output on the display device are compared with the display update prohibited area data DARA on the display device (step S305). When the pixel data DDOT (i) and the display update prohibited area data DARA overlap, that is, when the display position of the pixel data DDOT (i) is within the display update prohibited area, the display of the pixel data DDOT (i) is updated. The display attributes ATT are changed so as not to overlap, and if they do not overlap, the process proceeds to step S308 and subsequent steps (step S308).
306, step S307). Next, 1 is added to the subscript i to proceed to the processing of the next pixel data (step S30).

Then, in step S304, the image data DDR
When the processing of all pixel data DDOT (i) constituting W is completed, the processed image data is converted to DDR.
If the numerical data indicated by the numerical data designation command CNUM does not exist in the screen layout data DLYT in step S301, the image data DDRW is transmitted as it is as DDRW '(step S309).

FIG. 4 shows an example of a screen display according to the above-described processing procedure. In FIG. 4A, the scroll display is realized by the processing program being operated and the display of the processing program display 401 being continuously updated to display the vicinity of the block being executed. In the example of FIG. 4A, when the function key 402 is pressed, the area of the machining program display 401 is registered as a display update prohibition area. FIG. 4 (B)
FIG. 4A is a display example after the function key 402 is pressed in FIG. Since the image data relating to the processing program display 403 is registered in the display update prohibited area, the display is not updated, and as a result, the screen scroll accompanying the operation of the processing program is not performed. Further, a guide 404 indicating that updating of the display of the machining program display 403 is prohibited is displayed. Here, when the function key 405 is pressed, the guide 404 is deleted, and the display update prohibition area is released, so that the screen scroll of the machining program display 403 is restarted.

In this embodiment, the specified numerical data and the screen layout data are used as a method of obtaining the display update prohibited area. However, this is displayed by directly specifying an arbitrary coordinate value on the display device. A method of determining an update prohibited area is also conceivable. Further, in the present embodiment, the display update prohibited area is rectangular, but a method of forming an arbitrary polygon or circle may be considered. Further, two or more display update prohibited areas may be registered, and each may be set as a display update prohibited area.

In addition, a method of transferring the pixel data of the display update prohibited area specified already to an arbitrary area in the display device and re-registering the transferred area as the display update prohibited area is also conceivable. In this case, the display update prohibition area data DA in step S302 in the flowchart of FIG.
The RA may be the re-registered area. FIG. 5 is an example of a screen display in a state where the display update prohibited area has been transferred to another area. In FIG. 5A, an alarm having the content indicated by the guidance 501 is generated, and the processing is stopped. Here, the area of the guidance 501 and the area of the machining program display are registered as display update prohibition areas.
The case where pixel data of the area 1 is transferred will be described as an example. When the function key 502 is pressed in FIG. 5A, the image data including the guidance 501 is transferred to another area specified in advance, the transfer destination area is re-registered as a display update prohibition area, and the transfer source area is changed. Registration is canceled.

FIG. 5B is a display example after the function key 502 for instructing the change (re-registration) of the display update prohibited area in FIG. 5A is pressed. FIG.
In (B), the alarm has already been released and the machining program is running, but the display of the guide 503 relating to the alarm re-registered as the display update prohibited area is kept as it is, and the update of the display of the guide 503 is prohibited. Is displayed. Thereafter, when the function key 505 is pressed, the guide 504 is erased, the display update prohibited area is released, and the display of the guide 503 is erased by updating the display based on the image data originally displayed at this position. You. FIG. 5 (B)
If an alarm occurs again in the state of, a new guidance regarding the alarm is displayed in the display area above the guidance 501 together with the display held in the guidance 503. Although the size of the display update prohibited area does not change before and after the transfer of the image data in the example of FIG. 5, it is possible to enlarge or reduce the size according to the size of the transfer destination area. .
