As shown in FIG. 6C, in the case of a counter, a reset key (section C1b in FIG. 6A) is displayed in pairs on the right side of the count value.

Next, in step 220, the above step 1
In order to exchange signals between the addresses set in the various display screen definition matrices read by 00 to 120 and the addresses of the programmable controller 10,
The address of the programmable controller 10 is set. In the lamp display, each section set on the display 26 of the operation panel 20 is associated with the address of the programmable controller 10. For example, FIG.
As for the section indicated by A1 in (a), since “M000” is input in the “lighting address” corresponding to the symbol “A1” in the lamp display screen definition matrix in FIG. 4B, the section “A1” The address "M000" is associated with. In addition, the lamp display colors of the "background color" and the "character color" when the lamp is ON and the "background color" and the "character color" when the lamp is OFF are associated with each of the associated addresses (sections). The association is performed as shown in FIG.

In the switch display, each section set on the display 26 of the operation panel 20 is associated with the address of the programmable controller 10. For example, regarding the section indicated by the symbol “B1” in FIG.
“M001” in the “execution address” corresponding to the symbol “B1” in the switch display screen definition matrix in FIG. 5B.
Since it has been input, the address “M0
01 ”is associated.

In the counter display, each section set on the display 26 of the operation panel 20 is associated with the address of the programmable controller 10 in which the counter value is stored. For example, for the section indicated by the symbol “C1” in FIG. 6A, “D0000” is input to the “counter address” corresponding to the symbol “C1” in the counter display screen definition matrix in FIG. 6B. Therefore, the address “D0000” is associated with the section “C1”. The section "C1" to the right of the section "C1" that displays this counter
The reset key for resetting the count value displayed in the section “C1” is displayed in a pair in “b”, and the address of “reset output” for inputting a reset signal is associated with the section “C1b”. Is set.

Regarding this counter display, only the correspondence between the partition and the address of the programmable controller 10 is set, and a sequence program for counter display is required to operate the counter to be displayed. The creation of the sequence program for displaying the counter will be described later in step 240. When the process of step 220 described above ends, the process moves to the next step 230. In this step
It is determined whether or not the parameter for displaying the counter is input to the counter display screen definition matrix read in step 20. If the parameter for displaying the counter is not input, the process is terminated, and the process proceeds to step 140. When the parameter for displaying the counter is input to the counter display screen definition matrix read in step 120, the process proceeds to step 240. The details of the process of step 240 are shown in the flowchart of FIG. Note that the following steps 300 to 320
The sequence diagram shown in FIG. 8A is used to describe the process of FIG. 8A, but these processes are performed inside the CPU 31 and are not displayed on the display 34.

In step 300, the address entered in the "count input" corresponding to each section from the counter screen definition matrix entered in step 120 is shown in FIG.
It is set to the address A shown in (a). For example, FIG.
"X000" is displayed in the "count input" corresponding to the symbol "C1" in the counter display screen definition matrix in (b).
Since "X000" has been input, "X000" is set in the address A.

In step 310, as in step 300, the address input to the "reset output" corresponding to each section is set to the address B shown in FIG. 8A from the counter screen definition matrix input in step 120. To do. For example, since "Y000" is input to the "reset output" corresponding to the symbol "C1" in the counter display screen definition matrix of FIG. 6B, "Y000" is set to the address B.

In step 320, as in step 300, the "counter address" corresponding to each section is calculated from the counter screen definition matrix input in step 120.
The address input to is set to the address C shown in FIG. For example, since "D0000" is entered in the "counter address" corresponding to the symbol "C1" in the counter display screen definition matrix in FIG. 6B,
“D0000” is set in the address C.

When the setting of each address is completed in steps 300 to 320 in this way, the process proceeds to step 330 and the addresses A, B, and B of the contacts are stored in the RAM 36 in advance as shown in FIG. The counter display sequence program is completed by associating the address name with each variable name of the sequence program in which C is described as a variable name. For example, for the "symbol" C1 of the counter display definition screen matrix shown in FIG. 6B, the counter display sequence program as shown in FIG. 8C is completed. In this way, the counter display sequence program is completed, and the counter display sequence program is stored in the area 36h of the RAM 36.

The value "X" of "CNT X" in the counter display sequence program is a counter address provided inside the programmable controller 10, and is the numerical value of the address "X000" which is "count input". Is an address that turns on each time the counter counts up, and "k = C" sets the number of times "X" is turned on to k, and the value of this k is set to "C0".
000 ".

When the creation of this sequence program is completed, the process of step 130 of FIG. 2 is completed and the process proceeds to the next step 140. In step 140, the operation panel 20
Converted to a data format that can be handled by R and used as screen definition data.
It is stored in the area 36g of the AM 36. At step 150, the operation panel 20 stored in the area 36g of the RAM 36 is stored.
The screen definition data converted into the data format for the computer is transferred to the operation panel 20 via the interface 37. Operation panel 2
By storing the transferred screen definition data in the RAM 24 on the 0 side, the processing of the screen definition data of the operation panel 20 is completed.

The lamp display thus defined on the screen,
The switch display and the counter display can be displayed on the display 26 by operating an unillustrated selection switch on the operation panel 20. Next, the display and operation of the lamps, switches, and counters displayed on the display 26 of the operation panel 20 that operates based on the screen definition data described above will be described.

The lamp display performs the operation input to the lamp display screen definition matrix by executing the flowchart shown in FIG. 9 at predetermined time intervals while the operation panel 20 is operating. This processing will be described below. Step 40

In step 410, based on the ON / OFF state of the address read in step 400 and the lamp display color set in the correspondence table of each address and lamp display color shown in FIG. 4D, the display 26 is displayed. Change the display color of the lamp displayed on the screen. By this processing, for example, the section A on the display 26 in FIG.
When the address M000 of the programmable controller 10 is ON, the lamp displayed in 1 displays the switch background color in red and the characters are white, and when the address M000 of the programmable controller 10 is OFF, the background color of the switch is Is displayed in white and the characters are displayed in black.

Next, regarding the switch display, when the "Switch No. 1" portion displayed in the section B1 shown in FIG. 5 (a) on the display 26 of the operation panel 20 is touched, the address M001 of the programmable controller 10 is set to ON. To do. The counter display is “reset” displayed in the section Cb shown in FIG. 6A on the display 26 of the operation panel 20.
6 is touched, the address YOOO of the programmable controller is set to ON, and when the address YOOO of this programmable controller is turned ON,
The content of the address D0000 in which the data of the count value displayed in the section C1 shown in (a) is entered is set to zero.

Since the data transferred to the operation panel 20 is screen definition data, the counter display sequence program is set by setting a floppy disk (not shown) in the floppy drive device 32 and operating the keyboard 35. The counter display sequence program stored in the area 36h of the RAM 36 is read out and stored in a floppy disk, and this floppy disk is set in the programmer 40 and read. By this operation, the sequence program for displaying the counter is additionally stored in an area (not shown) for storing the user program of the programmable controller 10, and the counter can be displayed on the display 26 of the operation panel 20.

As described above, when defining the screen, the lamps, switches, and counters can be displayed on the display 26 of the operation panel 20 simply by inputting parameters to various screen definition matrices. Also, a sequence program for the counter necessary to display the counter can be created based on the counter screen definition matrix.

In this embodiment, an example in which a matrix for screen definition is provided for each of the lamp, the switch and the counter has been described, but items indicating the types of the lamp, the switch and the counter are provided on one matrix. The screen may be defined by using one matrix. Further, the same section may be designated as the section for displaying the lamp and the switch, and the lamp and the switch may be displayed in an overlapping manner. Although the counter display sequence program is input to the programmer by a floppy disk, it may be automatically transferred to the programmer using a communication cable or the like.

Further, although the counter display is performed in this embodiment, the timer display is also applicable. Further, in the present embodiment, in the case of the counter display, the sequence program for the counter display is created, but also in the lamp display and the switch display, when the plurality of conditions are satisfied, the programmable controller 10 and the signal You may be able to give and receive. In this case, similar to the counter (FIG. 6 (b),
As shown in FIG. 8B), various addresses can be set automatically in various screen definition matrices, and a sequence program in which each contact is described by a variable name is prepared in advance to automatically execute various display sequence programs. Can be created.

[0042]

As described above, according to the present invention, it is possible to draw a screen to be displayed on the operation panel by only inputting parameters to the screen definition matrix and without being aware of the size and shape of the lamp and operation keys. Can be done easily.
Also, since the operation keys and lamps can be automatically associated with the addresses of the programmable controller based on the screen definition matrix, not only the man-hours required for screen definition can be reduced, but also a setting error occurs during association. There is nothing to do.

Further, when the counter is displayed, the sequence program necessary for displaying the counter can be automatically created, so that even an operator who does not have knowledge of the sequence program can easily define the screen without complicated operations. It can be carried out.
