DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for preparing data of a display such as a touch panel.

[0002]

2. Description of the Related Art A display device such as a touch panel inputs a command by touching a display point (hereinafter, referred to as a lamp) formed by graphic data displayed on a screen, and inputs a command to the display. By turning on or off, you can check the meaning of the figure or output a control command.By changing the graphic data, you can change the display content as appropriate, check various contents, It is an input / output device that can issue commands.

In recent years, such a display has been used as an input / output device for controlling equipment on a production line in a factory. FIG. 8 is a diagram for explaining a conventional operation for turning on and off a lamp displayed on a screen of a display device.

[0004] In a display device used in such a production facility, one output coil in a sequence circuit of a PC (programmable controller) controlling the equipment and the like is displayed on the display device. Lighting and extinguishing of the lamp are performed corresponding to the lamp. For this reason, the output coil 1 is displayed in such a manner that the coil R100 is displayed on the lamp 1 of the first screen displayed on the display, the lamp R101 is displayed on the lamp 2,.
As shown in FIG. 9, a data table is created in which the lamp address of the display and the absolute address of the coil correspond one-to-one, and a coil is generated according to the correspondence of the data table. Is turned on and off by the output of the lamp on the display screen.

[0005]

Normally, up to eight such display units can be connected to one PC, and one display unit has, for example, 10 lamps per screen. In this case, the number of screens can be 255. Of course, the number of such lamps and the number of screens vary depending on the specifications of the display device, but usually it is possible to have such a number of lamps and screens.

Accordingly, in the above case, the number of output coils for controlling the lamp of this display with one PC is 8 displays, 255 screens per display, and 10 screens per lamp. , So 20400 are needed.

However, if a large number of output coils are used for the display as described above, the number of output coils possessed by the PC is limited, so that it is used for equipment controlled by the PC. The number of output coils will be reduced.

For this reason, in general, the number of displays controlled by the PC or the number of screens or lamps displayed on the connected display is reduced, such as by holding the PC or the display. In many cases, facilities are used without maximizing their capacity, and there is a problem that equipment resources cannot be used effectively.

Further, when the number of lamps, such as the number of display devices, the number of display screens, and the number of lamps, is increased due to a change in a production line or a procedure in each process, the number of output coils becomes insufficient. It is necessary to replace it with a large one, or it is necessary to design the entire system in advance to increase the number of lamps due to such a change,
Installing large PCs in anticipation of future changes will lead to an increase in capital investment, and planning all changes in the future itself will require a great deal of labor and difficulty. It is.

Accordingly, an object of the present invention is to reduce the number of output coils used for lamp display of a display, and to use a display with a small number of output coils so that the capabilities of the display and the PC can be used to the maximum. The purpose is to provide a method of preparing data for a vessel.

[0011]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a method of producing data of a display, in which a display point in a display screen is turned on and off in response to an output of an output coil of a programmable controller.

And a step of creating a correspondence table for making a correspondence with each of the screens described above.

In the present invention, in the step of copying the data table by the number of the plurality of screens, the address of the data table to be copied for each screen is shifted by an arbitrary offset amount. It is a creation method.

Further, the present invention is a method of creating data for a display, comprising a step of editing a data table copied for each screen for each screen after the step of creating the correspondence table. .

[0015]

The present invention constructed as described above is used because a data table for one screen is created and this data is copied to another screen to create all data of the display. Regardless of the number of screens, the number of output coils can be reduced to the number of output coils for one screen. Also, once a screen is designed, it is sufficient to copy the output coil. Can be.

Also, according to the present invention, even when there are a plurality of displays, data of any one screen of any one of the displays is created, and this data is copied to another display and another screen to display the data. We decided to create all the data for
Regardless of the number of screens, the number of output coils to be used can be reduced to the number of output coils for one screen per display unit, and once the design for one screen is completed, the copy is sufficient. And the number of design errors can be reduced.

In the present invention, when copying the data of one screen, the data table address is offset for each screen and copied, so that separate and independent data having different addresses for each screen is created. .

Further, in the present invention, by editing data created by copying for each screen, even on a screen having a display point different from other screens, only the screen needs to be edited. Eliminates the need to manipulate data.

[0019]

An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is an example showing a general equipment configuration to which a plurality of displays are connected. In this facility, eight displays 1 to 8 are controlled by one PC 50, and the eight displays 1 to 8 are continuously connected via an input / output interface (I / F) 51 of the PC 50. The display devices 1 to 8 are connected to each other, and an identification number (ID) indicating the display device is assigned to the display devices.

In the PC 50, a sequence program 55 for controlling the display, a C-mode program 56 for searching a data table described later, a storage area 57 for the data table created according to the present invention and a storage area for the correspondence table 58 are stored therein, and each program is executed by an arithmetic unit (not shown; the arithmetic unit is a CPU, an MPU, or the like) in the PC 50, and a lamp on the screen displayed on the display is displayed. The lights are turned off. This display operation will be described later.

A method for creating display data in this apparatus will be described with reference to a flowchart shown in FIG. In the following description (S number) is the step number in FIG.

First, before data creation, a screen is created on each display (S1). On the display screen, a screen configuration such as graphic data such as the shape and position of each lamp in the screen and comments on display contents is created. Then, data is created for turning on and off the lamp on the display.

In the data creation, first, an address (hereinafter, referred to as a lamp address) for each lamp, which is a display point based on graphic data on the screen, is assigned to one screen having an arbitrarily selected display device (referred to as a lamp address). S
2) After the assignment of the lamp address on one screen is completed, the absolute address of the output coil for controlling each lamp on this screen is assigned (S3). Thereby, a data table for one screen in which one lamp and one output coil in one arbitrary screen are associated with each other on a one-to-one basis is created.

In this embodiment, data is created for the first screen of the display # 1, and ten lamps are displayed, and the lamp address starts from 141000.
The address of lamp 1 is 141000, the absolute address of the output coil corresponding to lamp 1 is 09000 (output coil R100), and so on.
Is 141001 and the absolute address of the coil is 09002
(R101), the lamp 3 has 141002 and the absolute address of the coil is 09004 (R102) ... The lamp 10 has 14109 and the absolute address of the coil is 09018 (R109). This completes a data table for one screen. The resulting data is shown in FIG.

Thereafter, the completed data table for one screen is copied for a plurality of screens by offsetting the lamp address, so that the data table is stored in the data table storage area 57 in the PC 50 and stored for one display. A data table is completed (S4). In the case of this embodiment, since one display has 255 screens, the creation of the data of the first screen has been completed, so that the data of 254 screens is copied. At this time, the offset applied to the lamp address is set to 100, and the second screen on the display # 1 is 14110.
0 is the start address, and the third screen is 14120 in order.
.. Become 141300 for the 0th and 4th screens, and 166400 for the 255th screen which is the final screen.

The data table created for this one display is copied by offsetting the lamp address and the absolute address of the output coil by the number of displays and stored in the data table storage area 57 (S).
5). In the case of the present embodiment, since the display # 1 has already been completed, the remaining seven units are copied. Assuming that the offset of the lamp address at this time is 100,000, the lamp address is indicated by 241000 to 2664000 in the display # 2.
And display # 3 is 341000-366400.
0, and up to display # 8 in the following order. Then, the absolute address of the output coil is multiplied by 100 and the number of lamps is equal to several tens of lamps.
０09118 to ２００09118 in the display # 3.
Up to 18.

With this, a data table for each screen on each display is completed. However, some screens having the display have screens which have display lamps which are not provided on other screens.
If there is such a lamp that is not present on another screen, that is, a unique display point, the data table is edited for each screen and associated with the output coil (S6). For example, if the number of lamps to be displayed is 11 on the third screen of the display # 3, there is only 10 output coils in the correspondence between the lamps and the output coils created so far. For output lamps, add output coil assignments. Conversely, if the number of lamps is one less than nine, the extra copied lamps are deleted from the data table. FIG. 4 shows the data table thus completed.

Next, a correspondence table is created for each screen in which the addresses starting from are associated (S
7). FIG. 5 is a correspondence table according to the present embodiment, which is associated so that the starting lamp address of each screen in each display unit can be determined from the starting address. From this correspondence table, it can be seen that the first screen of the display # 1 starts from the 141000 address, and similarly, the second screen of the display # 1 changes from 141100 to. This correspondence table shows which screen data of which display unit starts from which address.

FIG. 6 is a diagram for explaining the correspondence between the data created in this way and the sequence circuit. FIG. 6 shows a sequence circuit for controlling each screen for each screen and its display screen. It is different from the conventional one (Fig. 8
), The same output coil will be used on different screens. It should be noted that in FIG.
Although the number of lamps is shown, the number of lamps on each screen is 10 in this embodiment. Like this one
In one display, the same output coil is used for each screen, that is, the lamp 1 for the first screen, the lamp 1 for the second screen,... The lamp 2 on the second screen, the lamp 2 on the second screen,..., The lamp 2 on the 255th screen all have one output coil commonly used for a plurality of screens, such as the output coil of R101. This is because different screens are not displayed at the same time on one display,
This is because it is not necessary to assign different coils to all lamps for each screen.

As described above, by applying the present invention, the data of the display device is created for one screen, and thereafter, the data for one screen is copied for a plurality of screens and further for a plurality of display devices. This allows all data to be created and uses fewer output coils.

Next, the operation of displaying data on the display using the data table (FIG. 4) and the correspondence table (FIG. 5) created as described above will be described with reference to the flowchart shown in FIG. .

The lamp lighting operation on the screen displayed on the display is performed by executing the sequence program 55 and the C mode program 56 in the PC 50. First, the C mode program 56 is displayed on each display. It recognizes which screen is being displayed (S10), starts a sequence program (see FIG. 6) corresponding to the recognized display screen, and turns on and off the output coil according to the execution of the sequence program. (S11) The C-mode program searches the corresponding table from the recognized screen to obtain the head address of the data table for controlling each lamp in this screen (S1).
2) The correspondence between the output coil and each lamp in the display screen is searched from the data table (S13), and the lamp on the display screen is turned on and off as the output coil is turned on and off (S14).

By creating the data table and the correspondence table as described above, the number of output coils required for each display device is determined by the number of output coils for performing lamp control for one screen, and the number of singular display points. This can be done by the number of output coils for this singular display point. That is, in the case of the present embodiment, since the number of lamps on one screen is ten, the total of eleven output coils including the ten output coils and the one output coil which is a unique display point is one. Since all the lamps for 255 screens displayed on one display can be controlled, and eight displays are connected, the number of lamps is 20400, and the output of 20400 in the related art What has been necessary for the coil can be controlled by applying the present invention to output coils for 80 plus the unique display points.

[0035]

As described above, according to the present invention,
Since a data table for at least one screen is created and is copied for a plurality of screens, the creation of display data can be completed for one screen, and the number of output coils used is reduced to the number of screens. Regardless, it can be covered by the output coil for one screen. Further, since the screen data to be actually created is sufficient for one screen, design man-hours can be reduced, design errors are reduced, and data quality is improved. Further, the copied data is made into a subroutine for each screen and is independent, so that it is possible to edit each screen data.

Further, even when there are a plurality of displays, a data table for one screen of a certain display is created,
By copying this data for a plurality of screens and further for a plurality of display devices, the display device data can be created for one screen, and the number of design steps can be reduced.
