Description

Description: TECHNICAL FIELD The present invention relates to a numerical control device that has a display means and is open to the user for screen creation. [Prior Art] FIG. 3 is a block diagram showing a configuration example of a conventional numerical control apparatus. In the figure, 1 is a display means such as a CRT (cathode ray tube), 2 is a display control means for controlling the display of the display means 1, 3 is an input means for inputting a processing program and the like, 4 is a central processing means (CPU), 5 Is an output means, 6 is a parameter setting means for switching valid / invalid of screen creation open to the user, 7 is a screen creating means for creating a user's own screen on the screen open to the user, and 8 is a screen creating A screen data storage memory for storing screen data created by the user using the means 7, a memory for storing data input by the input means 3 and data calculated by the central processing means 4, 10 an input means 3 It is ROMization means for ROMizing the machining program and sequence program input in step 1, and the screen data set by the screen creation means 7. FIG. 4 is a diagram showing an example of creating a screen open to the user in the numerical control device of FIG. In the figure,
The bottom line is the data setting part created by the manufacturer in advance. The screen () that specifies the screen, NO () that specifies the position in Katsuko to set the data, and the data of the specified data input part. It consists of () and. Except for the bottom line, the screen creation usable part is a range that can be used by the user when creating a screen, and the portion where data is desired to be set later is shown in Katsuko. FIG. 5 is a flow chart for explaining the operation of the numerical controller of FIG. Next, the operation of the conventional numerical controller shown in FIG. 3 will be described. In addition to the screen pre-configured by the maker, the user also creates a screen unique to the user by the screen creating unit 7 by enabling the parameter used by the parameter setting unit 6 for creating the screen to the user. The screen data can be stored in the screen data storage memory 8. The user appropriately displays the screen created as described above through the display control means 2 and the display means 1
Can be displayed. Also, by invalidating screen creation, specifying the NO in Katsuko you want to set the data to NO () and entering the numerical value in the data (), you can rewrite the data in the specified Katsuko on the screen. [Problems to be Solved by the Invention] Since the above-described conventional numerical control device in which screen creation is open to the user is configured as described above, if the screen data storage memory 8 is ROMized as a system, The screen opened to the user can be used only as a fixed screen, and in order to allow the user to input the setting data and the like linked with the machining program, the screen must be in the RAM state. However, in that case, there are problems that the system goes down due to an erroneous operation, or the setting data is carelessly input to change the machining route. The present invention has been made to solve such a problem, and data can be set and the setting data can be carelessly input in a state in which the screen opened to the user is ROMized and protected. The purpose is to obtain a numerical control device that can be protected so that it does not exist. [Means for Solving Problems] A numerical control device according to the present invention separates data relating to display of a screen opened to a user into screen configuration data (fixed data) and setting data (variable data), and stores in ROM. In the case of, it is possible to make ROM only for the screen configuration data, and also to protect the writing of the setting data so that it will not be accidentally rewritten when the setting data is input. Is. [Operation] In the numerical control device of the present invention, the data related to the display of the screen opened to the user is separated into the screen configuration data and the setting data, and the screen configuration data is converted into a machining program,
Make it possible to put it in ROM like a sequence program. [Embodiment] FIG. 1 is a block diagram showing an example of the configuration of a numerical controller according to an embodiment of the present invention. The same or corresponding parts as in FIG. The description is omitted. In the figure, 31 is a setting data write protect means for protecting writing of setting data to a screen opened to the user, 32 is a screen configuration data storage memory for storing the configuration data of the screen created by the user, and 33 is created by the user. It is a setting data storage memory for storing the data set in the selected screen. FIG. 2 is a flow chart for explaining the operation of the numerical controller of FIG. Next, the operation of the numerical controller according to the embodiment of the present invention shown in FIG. 1 will be described. When the screen is created using the screen open to the user, the parameter used by the parameter setting means 6 for creating the screen open to the user is validated. In this state, the screen can be created, and after calling the screen and setting the screen NO in the screen () shown in FIG. 4, the screen creating means 7 can be used to create the user's own screen. At this time, the place where data is to be set later is set as a cut like the example shown in FIG. After the screen is created, if the screen creation parameters are disabled, the next time the screen is called,
You can enter the data in the frame on the screen, but even in this case, to prevent accidental rewriting of the data, only when the setting data write protect means 31 is ON for writing, Data is writable inside. As mentioned above,
The screen data created with the screen creation enabled is stored in the screen configuration data storage memory 32 so that the screen data can be ROMized. Further, the setting data input when the screen creation is invalid and the writing of the setting data is ON is stored in the setting data storage memory 33 and can be rewritten at any time in the RAM state. In the above-described embodiment, the case where the screen setting is switched between valid and invalid by the parameter setting means 6 has been described, but it may be performed by an external switch or the like. Further, in the above-described embodiment, the switching of valid / invalid of screen creation and the write protection of the setting data are described as separate items, but both may be set as one unit. [Effects of the Invention] As described above, according to the present invention, in a numerical control device, data relating to display of a screen opened to the user is separated into screen configuration data and setting data, and the screen configuration data is processed into a machining program, a sequence program, or the like. Since it is configured so that it can be ROMized in the same manner as described above, it is possible to interactively protect the screen that the user has created independently, and when setting data is input, the setting data will be overwritten carelessly at any time. This has an excellent effect of preventing the above and obtaining a numerical controller with extremely high safety.
