DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system having a function of displaying the state of a controlled device and a function of controlling the operation of the controlled device. The present invention relates to an editor device for programming a control procedure and a recording medium on which an editor program is recorded.

[0002]

2. Description of the Related Art An industrial control device called a programmable logic controller (hereinafter, referred to as a PLC) or the like includes a hardware portion mainly including a CPU and a memory for realizing various controls including a sequence control. And a software part for controlling. The software portion includes designing a sequence control flow for operating the PLC according to the control system originally designed, converting the control flow into a command, writing the command to a memory, and the like. Generally, this series of operations is called programming.

[0003] In such programming, a proprietary language is used so that a program can be easily created without having specialized knowledge of a computer, and various programming languages which are easy for a user to use have been developed one after another. It became so. Currently, IEC (International Elect
The Rotechnical Commission) has established a standard programming language (IEC 61131-3). They are SFC (Sequential Function Chart), LD (Ladde
r Diagram), IL (Instruction List), FBD (Functio
n Block Diagram) and ST (Structured Text).

[0004] As described above, an environment is being prepared so that programs can be developed using various programming languages. For example, a ladder diagram (LD) has been widely used in the past because a ladder circuit can be designed relatively easily using a relay symbol, and is a programming language most often used at present.
As a programming tool used in a programming operation using such a programming language, a programming software such as a ladder editor has been widely used. Since this software can create a ladder diagram or the like in a form including symbols in a computer device such as a personal computer, it is easy to create and edit a program.

On the other hand, the programmable display has a dot display screen, an operation input switch, and a host controller (P).
LC), and an operation display having a program memory for control such as operation input on a screen. In general, a programmable display performs a graphic display, so that it can be provided with functions such as an operation panel, a switch, and an indicator light, and various monitors for management such as an operation status of a control target device and work instructions, It has a function as a terminal for inputting setting values for devices.

[0006] In recent years, a P / L is mounted by mounting an input / output unit or the like for connecting a device to be controlled.
Programmable displays with C control functions have also appeared.

A control screen (display content program) displayed on such a programmable display can be created by a user using screen creation software (drawing editor). When creating a screen, the user configures a desired control screen using parts (marks) such as switches, lamps, numeric keys, a meter display, a graph display, and drawing functions provided by drawing software on a personal computer or the like. I do.

The created control screen is transferred to and stored in the programmable display as screen data. PLC
During the operation of, the programmable display displays each component or graphic on the control screen according to the operation state of the control target device based on data exchanged with the PLC.

By the way, creation of a control procedure program using a ladder editor or the like (programming) and creation of a display content program using a drawing editor (screen creation).
Is generally performed independently. For example, when creating a display content program based on the created control procedure program, create design data in which the names and addresses entered for each device at the time of creating the control procedure program are written down in a table format. Then, a display content program including definition of an I / O address is created with reference to the design data. Similarly, when a control procedure program is created based on the created display content program, work is performed based on design materials prepared in advance.

[0010] For example, a ladder diagram created by a ladder editor is shown in FIG.
As shown in FIG. 2A, the name, operation, comment, and the like of the device to be controlled (for example, a switch or a lamp) corresponding to the ladder symbol are written on the side of the ladder symbol. Such additional information of the ladder symbol is usually input by being assigned to the ladder symbol together with the address when the ladder editor assigns the address to the input ladder symbol.

On the other hand, on the screen created by the drawing editor, as shown in FIG. 22B, parts (for example, switches and lamps) drawn corresponding to the control target device are displayed.
Then, additional information relating to the part can be pasted and displayed. Such additional information is input by the drawing editor in association with the address when the component corresponding to the address is arranged on the base screen.

[0012]

However, in such a method, since the supplementary information is individually input to the ladder editor and the drawing editor, the more supplementary information to be input, the more time and labor are required. It costs. Further, since the additional information is written in the other program while referring to the design data corresponding to the one program, there is a possibility that the additional information may be erroneously input, and the erroneous input may make it difficult to debug the program. Furthermore, design materials corresponding to the created program must be prepared in advance,
As a result, there is a disadvantage that work efficiency is reduced.

The present invention has been made in view of the above circumstances, and an editor apparatus and an editor capable of simplifying input of supplementary information and efficiently creating a display content program and a control procedure program.

In the third display / control system, the user program and the user screen are stored in the data file 33.

In the above example, the procedure for executing either the drawing or the programming first and then the other is described. However, the present invention is not limited to this, and it is also possible to execute both in parallel. is there.

When the programming process (1) is executed first, the procedure shown in the flowchart of FIG. 14 is followed. Here, the ladder editor 32a and the drawing editor 32b are activated in the computer device 3, and the display unit 35a of the display 35 (see FIG. 18A) displays an editor screen for creating a user screen (first editor screen). ) window (hereinafter for displaying, drawing window called) 32 b ₁ and the user program editor screen for creating (second editor screen) for displaying a window (hereinafter, referred to as ladder window) as those 32a ₁ is opened at the same time I do. However, when executing the programming process (1) first, it is sufficient that at least the ladder editor 32a is activated.

[0089] First, in the ladder window 32a ₁ above,
A ladder instruction is described by arranging a ladder symbol for each input / output device 4 (S21). Next, attribute data including a variable name used for the described ladder instruction is input (S22), and the ladder symbol and attribute data are registered in a temporary file (S23). Thereafter, it is determined whether or not to end the programming process according to a user operation (S24). Here, if the processing is not to be ended, the process returns to S21, while if to be ended, the created user program is registered in the data file 33 (S25).

In the drawing (2) executed subsequently,
The procedure shown in the flowchart of FIG. 15 is performed.

[0091] First, whether the ladder symbol on the ladder window 32a ₁ is judged whether or not dragged by the mouse (S31), if it is dragged, the ladder symbol is dragged is dropped on drawing window 32 b ₁ Is determined (S32). Here, the drop of the ladder symbol is confirmed, in order to extract the common data for the ladder symbol is dropped, searches the database data file 33 (common data file section 33a ₂ or 33g or common database 33c) (S33).

Next, based on the function assigned to the variable name of the dragged ladder symbol, a dialog box D including a plurality of marks having the function is provided.
₁ (see FIG. 18B) is displayed (S34). Thereafter, one mark from a plurality of marks that are displayed in the dialog box D ₁ determines whether the selected (S3
5). If a mark has been selected, the mark is displayed on the browser (S36), and registered in a temporary file (S37). Then, it is determined whether or not to end the drawing processing according to the operation of the user (S38). Here, if the processing is not to be ended, the process returns to S31, while if the processing is to be ended, the created user screen is registered in the data file 33 (S39).

When creating a user program, the common data
Data to the common data file section 33a _TwoOr common data
When registered in the base 33c, the common data is

When creating a program, the common data is stored in the common data file unit 33.
g, the common data is temporarily registered in S38.
Register it in the polar file, and in S39, enter the graphic data file.
It is stored in the unit 33f.

The processes in S33 to S36 are provided to provide the user with a degree of freedom in selecting a mark. Therefore, if such a degree of freedom is not required and the mark is fixed to one type, the processing of S33 to S36 becomes unnecessary. In this case, for example, the fixed switch number data (part code) is registered in the database in advance.

Here, a specific example of the drawing processing (2) performed according to the procedure of the flowchart of FIG. 15 will be described.

[0096] First, as shown in FIG. 18 (a), on the ladder window 32a ₁ is a ladder symbol L 'representing the ladder symbol L and the lamp already represents the switch (input) by the ladder editor 32a (output) Is drawn. Along with this, data on switches and lamps are registered in the data file 33 as shown in FIG. Specifically, as for the switch, as the common data, the variable name “SW1” and the address “XB00
01 is registered, and as for the lamp, at least a variable name “LAMP1” and an address “YB0001” are registered as common data.

In this state, as shown in FIG.
Keep open the drawing window 32b _1. Furthermore, the ladder symbol L in the ladder window 32a ₁ is dropped after being dragged to drawing window 32 b _1,
As shown in FIG. 18 (b), the dialog box D ₁ is displayed in the drawing window 32 b _1.

When the ladder symbol L is dragged, as shown in FIG. 19, the ladder file 33a ₁ (common database 33c or common data file 33
The common data about the switch extracted from g) is temporarily stored in the clipboard CB. When the ladder symbol L is dragged, common data is provided from the clipboard CB to the drawing editor 32b. Screen editor 32b displays a dialog box D ₁ of the the switch on the basis of the common data.

[0099] When appropriate one mark from among a plurality of types of marks having the function of a switch in the dialog box D ₁ is selected, as shown in FIG. 18 (c), drawing the mark M that is selected window 32b with the browser display _1, the dialog box D ₂ including nameplate information (name plate "SW1") is displayed. Here, OK
When the button is clicked, the mark M and attribute data on the drawing window 32b ₁ is determined. This allows
As shown in Figure 19, the screen file 33b graphic data file section 33b ₁ and the common data file section 33b
₂ , the graphic data (parts) and the common data for the switch mark M are stored in association with each other.

When the data file 33 has the structure shown in FIG. 9, since the common data for the user program and the user screen is already stored in the data file 33, the common data provided from the clipboard CB to the drawing editor 32b is used. Is the graphic data file section 33f
Is stored only in

[0102] Consequently, as shown in FIG. 18 (d), the mark M ₁ of a switch including a faceplate "SW1" is drawn on drawing window 32 b _1. When the same operation is performed on the lamp, the nameplate “LAMP1” is obtained.
Illustrating the mark M ₂ of the switch, including the window 32b ₁
Draw on top.

[0102] Thus, the user ladder window 32a ₁ on it is not necessary to perform the work of inputting a common data tasks and required to draw ladder symbols switch, it can be created very easily the user program. Further, there is no need to input nameplate information again when creating the user screen.

On the other hand, when the drawing processing (1) is executed first, the procedure shown in the flowchart of FIG. 16 is followed. Here, in the computer device 3, is up ladder editor 32a and the screen editor 32b, the display unit 35a of the display 35 (see FIG. 20 (a)), the ladder window 32a ₁ and drawing the window 3
It is assumed that the 2b ₁ is open at the same time. However,
When executing the drawing processing (1) first, it is sufficient that at least the drawing editor 32b is activated.

[0104] First, in drawing the window 32 b ₁ above, to place the mark each input and output device 4 as a target (S4
1). Next, attribute data including common data (variable name and address) used for the arranged mark is input (S42), and the mark and attribute data are registered in a temporary file (S43). Thereafter, it is determined whether or not to end the programming process according to a user operation (S44). Here, if the processing is not to be ended, the process returns to S41, while if the processing is to be ended, the created user screen is registered in the data file 33 (S45).

The programming process (2) to be executed subsequently follows the procedure shown in the flowchart of FIG.

[0106] First, it is determined whether the mark on the drawing window 32 b ₁ is dragged (S51), if it is dragged, to determine whether a mark has been dragged is dropped on the ladder window 32a ₁ ( S5
2). Here, if the drop of the mark is confirmed, in order to extract the common data for the mark dropped, searches the database data file 33 (the image data file section 33b ₁ or 33f) (S5
3).

Next, based on the function included in the attribute data of the dragged mark, the common data (at least the variable name) is displayed together with the ladder symbol corresponding to the function (S54). After that, the displayed ladder symbol is registered in the temporary file (S5).
5). Then, it is determined whether or not to end the programming process according to a user operation (S56). If not, the process returns to S52, while if completed, the created user program is registered in the data file 33 (S57).

[0108] It should be noted that, when you create user screen, if you register the common data in the common data file section 33b ₂ or common database 33c, a common data, once registered to a temporary file in the S55, the common data file section 33a ₂ at S57 To be stored. When the common data is registered in the common data file unit 33g when the user screen is created, the common data is temporarily registered in the temporary file in S55, and stored in the command file unit 33e in S59.

Here, a specific example of the programming processing (2) performed according to the procedure of the flowchart of FIG. 17 will be described.

[0110] First, as shown in FIG. 20 (a), on the drawing window 32 b ₁ are marks M nameplate already represents the switch (input) by the screen editor 32 b "SW1"
Are arranged and drawn together with. Along with this, as shown in FIG. 21, at least data on switches is registered in the data file 33. Specifically, for the switch, at least a variable name “SW1” and an address “XB0001” are registered as variable data.

In this state, as shown in FIG.
Ladder window 32a₁Open. Furthermore, drawing
Window 32b₁Mark M is Rudder Wind
Cormorant 32a₁When dropped after being dragged to
As shown in FIG.
The ladder symbol L is the ladder window 32a.₁When drawn on
Both include supplementary information (“SW1”) such as comments.
Dialog box D _ThreeIs displayed.

When the mark M is dragged, as shown in FIG. 21, the address and nameplate information of the switch extracted from the screen file 33b (image data file section 33b ₁ ) are temporarily stored in the clipboard CB. Is done. Then, when the mark M is dragged,
Common data is from clipboard CB to ladder editor 3
2a. Ladder editor 32a displays a dialog box D ₃ of the ladder symbols allocated to the switch on the basis of the address and the name plate information (LD instruction).

Here, when the OK button is clicked,
Ladder symbol L and the attribute data on the ladder window 32a ₁ is fixed. Thereby, as shown in FIG.
The command file section 33a ₁ and common data file section 33a ₂ of the ladder file 33a, the command and attribute data is stored in association for the ladder symbol L corresponding to the switch.

[0114] Consequently, as shown in FIG. 20 (c), the ladder symbol L containing "SW1" as the name of the switch is drawn on the ladder window 32a _1.

[0115] Thus, the user ladder window 32a ₁ on it is not necessary to perform the work of inputting the tasks and the required attribute data for drawing a ladder symbol switch, it can be created very easily the user program. Further, it is not necessary to input a comment on the name of the input / output device 4 corresponding to the ladder symbol or the ladder symbol when the user program is created.

The ladder file 33a shown in FIG.
Also in the case of using a file as shown in (b), the nameplate information can be assigned to the ladder symbol as described above. The ladder file 33 is often used in a general ladder editor that does not use variables, and has an area for storing ladder instructions and operands and corresponding comments (additional information). Therefore, when the ladder file 33a is used, the drag and drop of the mark M causes the image data file section 33b ₁
Are copied to the operand and comment areas, respectively.

The ladder file 3 shown in FIG.
When assigning the comment registered in 3a to the nameplate information of the mark, the processing is performed in the reverse procedure to the above.
In this case, the above comment is stored in the common data file section 33b ₂ as the variable name with the name plate information.

As described above, in the first to third display / control systems according to the present embodiment, the attribute data of the ladder symbol is transferred to the screen file 33b by the copy function unit 32c.
And the attribute data of the mark is copied to the ladder file 33a. Thereby, the attribute data common to both the files 33a and 33b can be provided, and the attribute data between the files 33a and 33b can be easily associated.

In each display / control system, the copy function unit 32c assigns the ladder symbol accompanying information included in the created user program to the mark on the user screen, and assigns the mark to the mark included in the created user screen. The accompanying nameplate information is assigned to the ladder symbol as incidental information. As a result, when creating a user program and creating a user screen,
This eliminates the need to input additional information for the ladder symbol and nameplate information for the mark. Therefore, the input operation is simplified, and it is possible to prevent the different ladder symbols and marks corresponding to the same input / output device 4 from inputting different supplementary information.

Further, in each of the display / control systems described above, since the common data provided to the editor via the clipboard CB includes the additional information, it is easy to assign the additional information to the ladder symbol and the mark in the editor. Can be done. In addition, since the variable names are used as the supplementary information, the information is shared and the data management can be simplified. And ladder editor 3
Even if 2a is a commonly used general ladder editor using a ladder file 33a that does not include variable names as shown in FIG. 6B, it is possible to exchange additional information with the drawing editor 32b. it can.

In the present embodiment, an example is described in which a user screen or a user program is created based on the created user program or user screen, but the present invention is not limited to this. For example, the present invention includes only exchanging incidental information between a user program that has already been created and a user screen by a drag-and-drop or copy-and-paste operation.

The present invention is not limited to the ladder diagram,
Of course, the present invention is also applicable to programming in other languages including the five languages specified in IEC 61131-3.

As a result, similar to the above-described recording medium, the supplementary information is supplied from one editor process to the other editor process by the supplementary information supply, so that redundant input of the supplementary information by both editor processes can be avoided. . Therefore, the input of the supplementary information can be simplified, and the display content program and the control procedure program can be efficiently created. Also, by supplying the variable as supplementary information to the other editor means, the information is shared,
Data management can be simplified. Further, according to this recording medium, since the editor program includes either the first or second editor process and the supplementary information supply process, the first editor process and the second editor process are independent. The present invention can be applied to a form included in a program.

In the above two recording media, the supplementary information supply processing is such that the image block displayed on the editor screen of one editor processing is selected and copied on the editor screen of the other editor processing. In response to this, the supplementary information is supplied, and the first or second editor process refers to the common data to automatically draw the copied display symbol or control symbol together with the supplementary information.

This simplifies the operation for creating a program as in the case of the above-described editor device. Therefore, there is an effect that the display content program and the control procedure program can be more efficiently created.
