Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention is applicable to specifying one of a plurality of electrical circuit elements included in an electrical circuit diagram displayed by an illustrated programmer provided in a programmable M controller, for example. The present invention relates to a car wheel movement method that can be suitably implemented.

BACKGROUND ART When moving the cursor V in the past, above the display area,
A total of four switches are provided for moving the cursor in the down, left, and right directions, and each time the switch is pressed, the cursor moves by one movement unit in the direction corresponding to that switch. ing. In such prior art, in order to move the cursor to a position far away from the current position, the switch must be operated many times, resulting in poor operability and time.

Purpose An object of the present invention is to provide a cursor movement method that allows the cursor V to be moved to a desired position quickly and with simple operation.

Example FIG. 1 is a front view of one embodiment of the present invention.

Programmable I controller 1 (see Figure 4 below)
The illustrated programmer connected to can write, display, and monitor programs. This graphic programmer 2 includes a graphic display 3 equipped with a liquid crystal display screen that displays program contents in a ladder diagram, and a display block 5 designated by a cursor 4 in the ladder diagram displayed by the graphic display 8. It is provided with another display 6 equipped with a liquid crystal display screen for displaying the operating status of the electric circuit element being represented, and key manual means 7 for operating the program writing operation and moving the cursor 4. The display area of the graphical display 8 is divided into a plurality of display blocks 5 in a matrix of 9 columns and 2 rows. KANO v4 moves from position (x, y) to position (
/, m), and the cursor 4a at position (1, 1) can be moved to position (/, m) as shown in FIG.

m).

Referring to FIG. 8, a ladder diagram is displayed in the display area of the graphical display 8, and the display block 5 includes a display area 8 for displaying electric circuit elements, and a cursor display area 9 for displaying cursor ~4. and is included.

Electric circuit elements include, for example, relay contacts, timers, counters, and the like.

FIG. 4 is a block diagram showing the electrical configuration of the above-described embodiment. Through the operation of the key manual means 7, the value 1.degree. m inputted to designate the display block 5 is stored in the memory 11 of the processing circuit 10 realized by a microcomputer or the like. Based on (direct/, m) stored in this memory 11, the processing circuit 10 moves the cursor 4 to the position (1, m) on the graphical display 3. Also, the processing circuit 10 moves the cursor 4 to this position (l!, The operating state of the electric circuit element displayed by the display area 8 in the display block 5 specified in m) is displayed by the display '#i6 according to the operation of the programmable controller 1.

The content displayed by this display word 6 is, for example, vv-
This information includes numbers of contacts, timers, counters, etc., conduction status of relay contacts, current values of timers and counters, and information on their values, and is displayed using characters such as letters and numbers.

When moving the cursor 4 to a desired position, the key manual means 7 is operated using the operator 1 shown in FIG. First, the key 18 is operated to indicate that a line is being input, and then the values "1" and "0" are input. Next, the key 14 is operated to indicate the column, and after that, the baskets "1" and "2" are operated. Thereafter, the execution key 15 is operated. By operating the execution key 15, the cursor is moved to that position (10, 12). In this way, the cursor 4 can be freely moved to a desired position regardless of the current position of the cursor 1L/4. For this movement, the desired position can be input using the key manual means 7, and therefore the operation is simple and can be performed quickly.

The present invention is not only implemented in connection with the illustrated programmer connected to the sequence controller, but can also be implemented in connection with any device for the display of the same.

Effects As described above, according to the present invention, the cursor can be moved by inputting row and column values using the input means, so the movement is quick and the operation is simple.
