JPS60220407A - Cursor shift controller of display for numerical controller - Google Patents

Abstract

PURPOSE:To attain the cursor shift control is a data setting process by changing the selection between a cursor position fixed mode and a cursor position mobile mode according to the presence or absence of the information on the cursor shift control. CONSTITUTION:When a switching command to a setting mode is supplied from a key input means A, a screen display means B displays a setting screen of the data stored previously in a memory to a display device C and also displays a cursor D at a prescribed data setting position. Then a key input execution command is supplied from the means A. thus a data input processing means F writes the setting data stored in a key input buffer memory means E to the data setting position indicated by the cursor D. While a cursor shift control information discriminating means G checks whether or not control information is contained in the means E. Based on the result of this check, a cursor shift control means H moves the cursor D to the next data setting position.

Description

TECHNICAL FIELD OF THE INVENTION The present invention relates to a cursor movement controller for a display for a numerical control device.

Conventional technology and problems Setting data such as parameter values and offset values in a numerical control device is performed by displaying data setting information such as a set number and the corresponding data setting position on a display such as a CRT attached to the numerical control device. This was done by displaying a screen, inputting setting data from the keyboard, and then pressing the execution key, and the input data was input to the data setting position indicated by the cursor. In this case, does the cursor position after setting one data point to the original data setting position that was just set (this is called cursor position unchanged mode), or does it move to the next data setting position? (This is called cursor position movement mode).Therefore, in cursor position unchanged mode, when you want to change the cursor position, and in cursor position movement mode, when you do not want to change the cursor position, The cursor had to be moved by operating a cursor movement key every time one data input process was completed.

Purpose of the Invention The present invention improves these conventional drawbacks, and
The purpose of this is to enable the selection of cursor position unchanged mode and cursor position movement mode to be changed depending on the presence or absence of cursor movement control information input following setting data. The purpose is to enable cursor movement control at each time.

Structure of the Invention FIG. 1 is an explanatory diagram of the structure of the present invention. Key manual means A includes numeric keys and alphabet keys for inputting parameter values, offset values, etc., special keys for inputting cursor movement control information, and control keys for switching to data setting mode.

Various keys such as an input execution key for inputting an input execution command are provided. When a command to switch to the data setting mode is input from the key manual means A, the screen display means B causes the display device C to display a screen for setting data stored in advance in the memory, and moves the cursor D to a predetermined data setting. Display in position.

The setting data inputted from the key manual power means A is temporarily stored in the key human power buffer storage means E. Key human power means A
If cursor movement control information, for example ";" (ent of mark) is input following the setting data, this is also temporarily stored in the sofa storage means for key manual input. When a key manual execution command is input from the key manual power means A, the data input processing means F writes the setting data stored in the key manual power buffer storage means E at the data setting position indicated by the cursor D. Further, the cursor movement control information identification means G identifies whether or not cursor movement control information is stored in the key input buffer storage means E. and,
If the cursor movement control information is stored, the cursor movement control means H automatically moves the cursor D to the next data setting position after data input processing. When the cursor movement control information is not stored in the key manual buffer storage means E, the cursor movement control means H does not move the cursor, and the cursor D remains displayed at the original data setting position.

The operation of cursor movement control according to this embodiment will be described below. Note that although parameter settings will be explained below, the invention can be similarly applied to settings of offset values, etc.

When setting new parameters in the parameter setting area 4b of the RAM 4, first press the key PARAM of the function keys 36. When this key is pressed, the microcomputer 1 executes the process shown in FIG. 4, displays a parameter setting screen on the CRT as shown in FIG. 3, and moves the cursor K to the first data setting position. to be displayed. In addition, in the screen of Figure 3, PAI'lA? 1ETER is a display indicating that the screen is a parameter setting screen, and the parameter numbers 001 to 008 and the corresponding parameter values are displayed at the bottom. The parameter values are all 0 in the initial state. Furthermore, in the illustrated example, the cursor K indicating the first data setting position is displayed under parameter number 001, but it may be displayed under the parameter value corresponding to parameter number 001 as shown by the dotted line. .

To set parameters, first enter the parameter value,
Next, if you want to enter the cursor position movement mode, press a predetermined key among the special symbol keys 32 (for example, END OF BLOCK) to input cursor movement control information, and finally press the manual execution key 41. If you want to enter the cursor position unchanged mode, press the manual execution key 41 immediately without pressing the END OF BLOCK key. In the parameter setting mode, the microcomputer 1
The process consisting of steps S1 to S7 as shown in the figure is executed, and among the information input from the keyboard 9, data indicating parameter values is input into the temporary input buffer area 4a of the RAM 4, and when the manual execution key is pressed. Execute key manual processing when the key is entered. Specifically, this key manual processing is a process of writing the parameter value stored in the temporary buffer storage area into the parameter setting position of the parameter setting area 4b indicated by the cursor.

Further, when the key manual processing is completed, the microcomputer 1 identifies whether or not the temporary buffer storage area 4b contains cursor movement control information, and if the cursor movement control information is not included, erases the contents of the temporary buffer storage area 4b. Then, the process ends. Therefore, if cursor movement control information is not included, even if the manual execution key is pressed, the cursor remains at its original position (in the illustrated example, the location 001). On the other hand, if the temporary basso storage area 4b contains cursor movement control information, after moving the cursor K to the next data setting position,
The contents of the file are deleted and the process ends.

Therefore, in this case, the cursor will be displayed below 002, which is the next data setting position.

As described in detail, according to the present invention, when the cursor movement control information is included in the key manual buffer storage means in addition to setting data, the cursor position is moved to the next position after key manual processing. Since the cursor is automatically moved to the data setting position and such movement is not performed when cursor control movement information is not included, the selection between cursor position unchanged mode and cursor position movement mode is This has the effect of being able to be changed depending on the presence or absence of cursor movement control information that is input following the setting data. However, there is an advantage that the cursor can be moved during the process of data setting operations such as setting parameter values, and that the movement of the cursor can be controlled for each data setting.
