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. Generally, since a programmable display performs a graphic display, it can be provided with functions such as an operation panel, a switch, and an indicator light, and various kinds of management such as an operation status of a control target device (device) and a work instruction. It has a function as a monitor and a terminal for inputting setting values for the 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.

However, in such a method, an input operation for creating a display content program is required separately from an input operation for creating a control procedure program.
It takes a lot of time and effort. Further, since the other program is created while referring to the design data corresponding to the one program, an erroneous input may occur when the other program is created, and the erroneous input makes it difficult to debug the program. Further, design data corresponding to the created program must be prepared in advance, which causes a disadvantage that work efficiency is reduced.

[0011] As an invention made to solve such inconvenience, Japanese Patent Application Laid-Open No. 11-175326 discloses an invention.
An editor device that associates a ladder symbol with a mark arranged on a screen between a ladder editor for creating a ladder diagram and a drawing editor for creating a screen is disclosed.
In this editor device, for example, by dragging and dropping a ladder diagram symbol onto a drawing window of a drawing editor, the name and address of a control target device common to one symbol and at least one mark corresponding to this symbol are included. The attribute data is stored in the common database, and a mark corresponding to the symbol dragged to the drawing window is displayed with reference to the attribute data.

[0012]

However, in the editor apparatus disclosed in the above-mentioned publication, although the data is shared, it is possible to avoid re-input of duplicate data between the ladder editor and the drawing editor. It is necessary to provide a common database for storing attribute data separately from the ladder file for the ladder editor and the screen file for the drawing editor. Moreover, the created ladder diagram (user program) and screen (user screen)
Is finally registered in the ladder file and the screen file, respectively, because the attribute data described above is stored in both the files. Also, since attribute data is copied from the common database to the ladder file or screen file, when sharing data from an external system with the ladder file and screen file, copy the data from that system to the common database and then It is necessary to go through the procedure of copying to a file and a screen file.

As described above, the conventional editor apparatus has a disadvantage that the database is not efficiently used.

The present invention has been made in view of the above circumstances, and uses a database efficiently while maintaining the operability of a conventional editor device, which can avoid duplication of data. Still another object of the present invention is to provide an editor device and a recording medium on which an editor program is recorded, which can easily realize data sharing with an external system.

[0015]

The computer device 3 configured as described above
When the target system in which the input / output devices 4 are arranged is operated (on-line state), the created screen and the state of the site are displayed on the display 35 to function as a monitor for monitoring the operation status of the target system. And the input / output devices 4 in the target system are controlled. At this time, the computer device 3
Executes the user program created by the ladder editor 32a and stored in the ladder file 33a according to the control function program. On the other hand, the computer device 3 functions as an editor device for creating a user program or a user screen by activating the ladder editor 32a or the drawing editor 32b when the target system is not operating (off-line state).

Here, a procedure for creating a user program and a user screen in the first to third display / control systems will be described with reference to the flowcharts in FIGS.

As shown in FIG. 10, it is determined in advance whether a user screen is created (drawing) or a user program is created (programming) according to an input operation by the user (S11). When a user program is created first, a programming process (1) using the ladder editor 32a is executed (S12), and then the drawing editor 32
The image forming process (2) using b is executed (S13). On the other hand, when creating a user screen first, the drawing editor 3
The image forming process (1) using 2b is executed (S14), and then the programming process (2) using the ladder editor 32a is executed (S15).

Next, the created user program and user screen are stored in a predetermined storage location so as to be usable (S16). At this time, the first or second display /
In the control system, the user program and the user screen are temporarily stored in the data file 33, then downloaded to the PLC 2 and the programmable display 1, respectively, and stored in the memory. Alternatively, in the second display / control system, the user program and the user screen are temporarily stored in the data file 33, downloaded to the programmable display 1, and stored in the memory unit 12. 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. 11 is followed. Here, a ladder editor 32a and a drawing editor 32b are activated in the computer device 3, and an editor screen (first editor screen) for creating a user screen is displayed on a display unit 35a (see FIG. 15A) of the display 35. ) 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.

[0096] 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 such as a name and an address used for the described ladder instruction is input (S22), and the ladder symbol and the attribute data are registered in a temporary file (S2).
3). 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.
(S25).

In the drawing (2) executed subsequently,
According to the procedure shown in the flowchart of FIG.

First, attribute data on a ladder symbol (ladder command) registered in the ladder file 33a is imported into the screen file 33b (S31). Ladder symbol on the ladder window 32a ₁ is judged whether or not dragged by the mouse (S32), if it is dragged, it is determined whether the ladder symbol is dragged is dropped on drawing window 32 b ₁ ( S33). Here, the drop of the ladder symbol is confirmed, based on the functionality included in the attribute data for the ladder symbol is dragged, the dialog box D ₁ (FIG. 15 (c) references including a plurality of marks having the function ) Is displayed (S34).

In the above procedure, the attribute data of all ladder symbols created by the ladder editor 32a is
The data is collectively copied to the screen file 33b in advance by the import in S31. However, instead of this, the attribute data for one ladder symbol may be imported sequentially for each drag and drop. In particular, when creating a ladder diagram that contains a large number of ladder symbols, you can import attribute data all at once,
Processing efficiency can be improved. On the other hand, when creating a ladder diagram including a small number of ladder symbols, even if attribute data is sequentially imported, there is almost no reduction in processing efficiency. Therefore, it is desirable to select which import to use based on the size of the ladder diagram and other factors.

[0100] After that, when one mark from a plurality of marks that are displayed in the dialog box D ₁ is selected, and registers the mark to a temporary file (S35).
Then, it is determined whether or not to end the drawing process according to the operation of the user (S36). Here, if not to end, S
On the other hand, when the processing is to be terminated, the created user screen is registered in the screen file 33b (S37).

Here, a specific example of the drawing processing (2) performed according to the procedure of the flowchart of FIG. 12 will be described.

[0102] First, as shown in FIG. 15 (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, the ladder file 33a registers data on switches and lamps as shown in FIG. Specifically, for the switch, “SW1” as a name and “XB0001” as an address
Is registered at least. For the lamp, at least "LAMP1" as a name and "YB0001" as an address are registered.

In this state, as shown in FIG.
Keep open the drawing window 32b _1. Further, FIG.
When the ladder symbol L in the ladder window 32a ₁ as shown in (b) is dropped after being dragged to drawing window 32 b _1, as shown in FIG. 15 (c),
Dialog box D ₁ is displayed in the drawing window 32b _1.

As described above, the attribute data of all the ladder symbols created by the ladder editor 32a is collectively copied to the screen file 33b by import in advance. Alternatively, attribute data for one ladder symbol is imported for each drag and drop. This import is realized by temporarily storing the attribute data on the clipboard CB and then copying it to the screen file 33b as shown in FIG.

[0105] 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. 15 (d), drawing an image M of marks selected is displayed on the window 32 b _1, a dialog box D ₂ containing the attribute data (name "SW1" and the characteristic "oN") is displayed. Here, when the OK button is clicked, the mark M and attribute data on the drawing window 32b ₁ is confirmed, the graphic data file section 33b of the screen file 33b
₁ and the attribute data file section 33b _2, graphic data and attribute data are stored in association for the mark M of the switch (see Figure 16).

Therefore, the user can select the drawing window 3
2b ₁ on it is not necessary to perform the work of inputting the tasks and the required attribute data for drawing a mark switch, it can be created very easily the user screen.

On the other hand, when the drawing processing (1) is executed first, the procedure shown in the flowchart of FIG. 13 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. 17 (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.

[0108] 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 such as a name and an address used for the arranged mark are inputted (S42), and the mark and the 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 screen file 33b (S45).

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

First, the attribute data of the marks registered in the screen file 33b is previously stored in the ladder file 33.
a (S51). Drawing window 32b
It is determined whether the mark on ₁ has been dragged (S5).
2), when it is dragged, to determine whether a mark has been dragged is dropped on the ladder window 32a ₁ (S53). Here, if the drop of the mark is confirmed, the above attribute data is displayed together with the ladder symbol corresponding to the function based on the function included in the attribute data of the dragged mark (S54).

In the above procedure, the attribute data for all the marks arranged by the drawing editor 32b is
Ladder file 3 by import at 51
3a. However, instead of this, 1
Attribute data for one mark may be imported sequentially for each drag and drop.

Then, the displayed ladder symbol is registered in a temporary file (S55). Then, it is determined whether or not to end the programming process according to a user operation (S56). Here, if the processing is not to be ended, the process returns to S51, while if the processing is to be ended, the created user program is registered in the ladder file 33a (S57).

Here, a specific example of the programming process (2) performed according to the procedure of the flowchart of FIG. 14 will be described.

[0114] First, as shown in FIG. 17 (a), on the drawing window 32 b ₁ has already been marked M is disposed and drawing representing a switch (input) by the screen editor 32b. Accordingly, the screen file 33b is
As shown in FIG. 8, data on the switch is registered. Specifically, at least “SW1” as a name and “XB0001” as an address are registered for the switch.

In this state, as shown in FIG.
Keep open the ladder window 32a _1. Further, FIG.
7 the mark M in the drawing window 32 b ₁ as shown in (b) is dropped after being dragged to the ladder window 32a _1, as shown in FIG. 17 (c), the ladder symbol L and dialog boxes D ₃ Ladder It is displayed in the window 32a _1.

As described above, the attribute data of all the marks arranged by the drawing editor 32b is copied in advance into the ladder file 33a by import. Alternatively, attribute data for one mark is imported for each drag and drop.
This import is realized by temporarily storing the attribute data on the clipboard CB and then copying it to the ladder file 33a as shown in FIG.

[0117] Then, as shown in FIG. 17 (c), together with the ladder symbol L is drawn on the ladder window 32a ₁ corresponding to the switch function, the attribute data (name "S
W1 ") dialog box D ₃ including displayed.
Here, when the OK button is clicked, the ladder symbol L and the attribute data on the ladder window 32a ₁ is confirmed, the command file section 33a of the ladder file 33a
₁ and the attribute data file section 33a _2, the command and attribute data is stored in association for the ladder symbol L of the switch (see Figure 18).

[0118] 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.

As described above, in the first to third display / control systems according to the present embodiment, the ladder editor 3
A ladder file 33a for storing the user program created in 2a, and a screen file 33b for storing the user screen created in the drawing editor 32b,
The copy function unit 32d is configured to copy the attribute data of the ladder symbol to the screen file 33b and to copy the attribute data of the mark to the ladder file 33a. As a result, both files 33a and 33b can have attribute data common to both files 33a and 33b.
Attribute data between 33b can be easily associated.

In addition, since the user program and the user screen have independent databases as described above, the above-described attribute data can be copied between each database and another database. Specifically, a database using general-purpose application software (spreadsheet software, etc.), a database for electronic circuit CAD, a database created by software for G code programming (machining programming) of the NC control device, and the like. Is selected as an image block by inputting data or the like on the operation input screen of the software, and the data is copied to the user program or the user screen database by dragging and dropping (or copying and pasting) as described above. I do.

In particular, when designing a control panel using CAD software (CAD software), it is effective to exchange data with a ladder editor and a drawing editor.

In order to develop any equipment system, an electrical system diagram including a mechanical design diagram is required.
In addition, in order to create an electrical system diagram, it is necessary to create an electrical specification, a control panel diagram, a parts list, and a hardware diagram (such as a circuit diagram). Then, based on the created electrical system diagram, a control panel is manufactured, and electrical work of an apparatus system in which the control panel is installed is advanced. Also,
In the process of designing and manufacturing a control panel, specifications are firstly agreed upon, and CAD is performed based on the specifications.
Using a tool for creating a drawing such as software, the electrical configuration is designed, and then a transition is made to the creation of a display / control system program including a PLC or the like. At this time, by using the function of the copy function unit 32d according to the present embodiment,
Data input by CAD software can be used to create a user program and a user screen.

Specifically, the application 32c of the computer device 3 (see FIGS. 1, 7 and 9)
When the D software is installed, the CAD software is started, and as shown in FIG.
To display the AD window 32c ₁ and the ladder window 32a _1. The CAD window 32c _1, PLC

, The ladder symbol L ₁ (LD instruction or the like) corresponding to the push button switch is displayed in the ladder window 32 in substantially the same procedure as the procedure shown in the flowchart of FIG.
It is displayed on a _1. Similarly, the pilot lamp also has a ladder symbol L ₂ (OUT command) as the ladder window 32a.

On the other hand, a user screen is displayed using CAD data.

The data to be imported into the ladder file 33a and the drawing file 33b at the time of the above processing are as follows:
As shown in FIG. 20, the application file 33c
Is stored in a CAD database constructed at the same time. Specifically, a symbol name, a comment, a PLC-related address, and the like are stored. PLC related address is PLC2
The address is assigned to a device such as a push button switch or a pilot lamp connected to the device. The figure symbol name is a symbol name given to a push button switch, a pilot lamp, or the like in the above-described figures created by CAD software. This graphic symbol name is associated with the above address, and is set to be the same as a variable used instead of an address when assigning an address such as a push button switch or a pilot lamp to a ladder symbol or mark. The comment is provided to indicate an operation state or the like of the device.

In the CAD database, by setting the symbol names and variables to be the same, the symbol names (names) and the PLC-related addresses (addresses) are attributed to the attribute data (FIGS. 6A and 6B). See). Thus, the ladder editor 32a and the drawing editor 32b display the graphic symbol names as variables together with the ladder symbols L ₁ and L ₂ and the mark M. Also,
The drawing editor 32b displays a comment “driving” on the mark M.

Here, in the third display / control system,
As shown in FIG. 9, since the computer device 3 having the editor function and the PLC function is connected to the open network 8, the database in the computer device 3 and the other systems A to Attribute data on ladder symbols and marks can be exchanged with a database such as C via a network. In addition, the same database can be shared between the computer device 3 and a remote system via a network.

In the second display / control system, if the programmable display 1 has an interface connectable to the open network 8, the programmable display 1 is connected to the open network 8 as shown in FIG. Computer device 3 or other system A via
To C or the like. In addition, the first display /
In the case of a control system, the programmable display 1 can be connected to the open network 8 in the same manner as in the second display / control system.
In the communication between the PLC 2 and the PLC 2, it is necessary to support different communication protocols for each manufacturer of the PLC 2. For this reason,
As described in Japanese Patent Application No. 10-117117 previously filed by the present applicant, a common communication protocol used for communication on the open network 8 and a communication protocol corresponding to the model of the PLC 2 are mutually exchanged. A function for conversion is provided in the programmable display 1.

In addition, when a plurality of user screens having different patterns are created for one user program,
Even when a plurality of PLCs 2 are connected to one programmable display 1 in the first display / control system, a link between one-to-many databases can be easily realized by copying data between databases.

Further, in the present embodiment, an example has been described in which the ladder window and the drawing window are displayed on the same display. However, the ladder window and the drawing window are displayed based on databases of different devices via a network. In this case, the present invention can be applied.

More specifically, as shown in FIG.
A database DB ₁ storing the user program downloaded to the PLC 2 in the first display / control system, and a database DB storing the user screen downloaded to the programmable display 1 in the second display / control system Data is exchanged between the _two . In this case, in the computer device 3, as shown in FIG.
a user program in the database DB ₁ which is displayed on a _1, drag between the user screen in the database DB ₂ to be displayed on the drawing window 32 b ₁ &
Ladder symbols and marks can be automatically generated by dropping. Therefore, editing and correction can be easily performed between the user program already downloaded to the PLC 2 and the user screen downloaded to the programmable display 1.

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.

[0133]

As described above, the editor apparatus of the present invention selects an image block displayed on one of the first and second editor screens with respect to data input on the editor screen, and In accordance with an operation of copying on the other editor screen, data common to the display content program and the control procedure program is stored in a display content program file for storing the display content program and a control procedure for storing the control procedure program. The configuration includes data copying means for copying data to and from a program file.

As a result, the data stored in one file is copied to the other file, so that a common database can be created between the two files.
As a result, there is no need to create a common database for both editors. In addition, it is possible to avoid duplicate data input by both editors. Therefore, there is an effect that the database can be used efficiently while simplifying the input operation.

In the above editor device, the first
Editor means draws the controlled devices and their states as image blocks on the first editor screen, while the second editor means displays control operations corresponding to the controlled devices on the second editor screen. A plurality of symbols are drawn as image blocks, the two editors input attribute data specifying each control target device, and the data copying unit is selected on one of the first or second editor screens. The attribute data associated with the selected image block is copied between the two files, and the other editor means corresponding to the copy destination file refers to the copied attribute data. Automatically draws an image block for the same controlled device as the controlled device to be controlled.

Thus, based on the image block previously created by one editor means and the attribute data associated therewith, the other editor means creates the image block and copies the attribute data. In addition, the image block can be easily created by the other editor means, and input of attribute data is not required. Therefore,
It is possible to improve the efficiency of creating the display content program and the control procedure program.

Further, in this editor device, the data copying means copies the attribute data before selecting and copying an image block. Thus, when the other program is created based on the already created program, the attribute data is collectively copied in advance before drawing the image block, or when both programs are created in parallel, one editor is used. Each time an image block is created on the screen, attribute data is sequentially copied. Therefore, there is an effect that the image block can be efficiently drawn according to the form of creating the program.

An editor device having any one of the above structures is
The data copying means selects an image block displayed on the operation screen with respect to data input on the operation input screen of the application program, and responds to the operation of copying the image block onto the first or second editor screen. Since data common to the display content program or the control procedure program and the data of the application program is copied to the display content program file or the control procedure program file, the display content program file or the control procedure program file is Data of application programs can be captured. Therefore, by using a database other than the database constructed in both program files, program development can be performed more efficiently, and program development can be incorporated as part of wider system development. Play.

The editor device having any one of the above structures
It is connected to a system different from the display / control system via a network, and the data copying means copies data between the two files and the system. The attribute data is copied. Therefore, there is an effect that the data can be easily shared with the external system.

The recording medium on which the editor program of the present invention is recorded is characterized in that the editor program executes a first editor process for creating a display content program in response to an input operation on a first editor screen, and a second control procedure program. A second editor process for creating in accordance with an input operation on the editor screen, and selecting an image block displayed on the editor screen with respect to data input on one of the first or second editor screens And stores the common data between the display content program and the control procedure program in the display content program file and the control procedure program in which the display content program is stored in accordance with the operation of copying the data to the other editor screen. And a data copy process for copying between the control procedure program file to be executed. .

Thus, similarly to the editor device of the present invention, data common to both programs is changed according to the selection of an image block on the second editor screen and the operation of copying it to the first editor screen. Copied between both files. Therefore, as a result of creating a common database between the two files, it is not necessary to create a common database for both editor processes, and it is also possible to avoid duplicate input of data by both editor processes. Therefore, there is an effect that the database can be used efficiently while simplifying the input operation.

In another recording medium on which the editor program of the present invention is recorded, the editor program includes a first editor processing or control procedure program for creating a display content program in response to an input operation on the first editor screen. 2
The configuration includes one of the second editor processes for creating in response to an input operation on the editor screen and the data copying process.

Thus, similarly to the recording medium described above, it is not necessary to create a database common to both editor processes, and it is possible to avoid data duplication by both editor processes. Further, according to this recording medium, the editor program includes either the first or second editor process and the data copying process, so that the first editor process and the second editor process are independent editor programs. The present invention can be applied to such a form.

In the above two recording media, the first editor process draws the controlled devices and their states as image blocks on the first editor screen, while the second editor process executes the second editor process. A plurality of symbols representing control operations corresponding to the control target device are drawn on the screen as image blocks, the two editor processes input attribute data specifying each control target device, and the data copy process performs one of the processes. The attribute data associated with the image block selected on the first or second editor screen is copied between the two files, and the attribute data copied to the other editor process corresponding to the copy destination file is copied. By referring to the image block of the same control target device as the control target device corresponding to the selected image block. It is allowed to automatically drawn.

As a result, similarly to the above-described editor device, it is easy to create an image block by the other editor process, and it is not necessary to input attribute data. Therefore, there is an effect that the creation efficiency of the display content program and the control procedure program can be improved.

In both recording media, the data copying process copies the attribute data prior to the selection and copying operation of the image block. Therefore, similar to the above-described editor device, the data copying process is performed prior to the drawing of the image block. The attribute data is copied in advance in a lump, or the attribute data is successively copied before each drawing of the image block. Therefore, there is an effect that the image block can be efficiently drawn according to the form of creating the program.

Alternatively, in the two recording media, the data copying process selects an image block displayed on the operation screen with respect to data input on the operation input screen of the application program, and executes the first or second editor. According to the operation of copying on the screen, data common to the display content program or the control procedure program and the data of the application program is copied to the display content program file or the control procedure program file. As with the above-described editor device, the display content program file or the control procedure program file can capture data of the application program. Therefore, by using a database other than the database constructed in both program files, program development can be performed more efficiently, and program development can be incorporated as part of wider system development.

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. Generally, since a programmable display performs a graphic display, it can be provided with functions such as an operation panel, a switch, and an indicator light, and various kinds of management such as an operation status of a control target device (device) and a work instruction. It has a function as a monitor and a terminal for inputting setting values for the 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.

However, in such a method, an input operation for creating a display content program is required separately from an input operation for creating a control procedure program.
It takes a lot of time and effort. Further, since the other program is created while referring to the design data corresponding to the one program, an erroneous input may occur when the other program is created, and the erroneous input makes it difficult to debug the program. Further, design data corresponding to the created program must be prepared in advance, which causes a disadvantage that work efficiency is reduced.

[0011] As an invention made to solve such inconvenience, Japanese Patent Application Laid-Open No. 11-175326 discloses an invention.
An editor device that associates a ladder symbol with a mark arranged on a screen between a ladder editor for creating a ladder diagram and a drawing editor for creating a screen is disclosed.
In this editor device, for example, by dragging and dropping a ladder diagram symbol onto a drawing window of a drawing editor, the name and address of a control target device common to one symbol and at least one mark corresponding to this symbol are included. The attribute data is stored in the common database, and a mark corresponding to the symbol dragged to the drawing window is displayed with reference to the attribute data.

[0012]

However, in the editor apparatus disclosed in the above-mentioned publication, although the data is shared, it is possible to avoid re-input of duplicate data between the ladder editor and the drawing editor. It is necessary to provide a common database for storing attribute data separately from the ladder file for the ladder editor and the screen file for the drawing editor. Moreover, the created ladder diagram (user program) and screen (user screen)
Is finally registered in the ladder file and the screen file, respectively, because the attribute data described above is stored in both the files. Also, since attribute data is copied from the common database to the ladder file or screen file, when sharing data from an external system with the ladder file and screen file, copy the data from that system to the common database and then It is necessary to go through the procedure of copying to a file and a screen file.

As described above, the conventional editor apparatus has a disadvantage that the database is not efficiently used.

The present invention has been made in view of the above circumstances, and uses a database efficiently while maintaining the operability of a conventional editor device, which can avoid duplication of data. Still another object of the present invention is to provide an editor device and a recording medium on which an editor program is recorded, which can easily realize data sharing with an external system.

The result of this allocation is stored in a ladder file 33a described later.

At the time of allocation, the memory unit 34 stores the device name corresponding to each address, using the input number and the output number as addresses. Conventionally, such allocation differs depending on the manufacturer of the PLC, and is set by an absolute address. Therefore, it is necessary to prepare a memory table corresponding to the manufacturer. However, the ladder editor 32a conforming to the IEC does not need the memory table as described above because the user can determine the input / output according to free variables. Also, the assignment once determined can be changed later.

As shown in FIG. 8, the memory section 34 has areas for respectively storing a display control system program, a communication protocol, screen data, a control function program, and a user program, as in the above-described SRAM 12c. are doing.

The computer device 3 configured as described above
When the target system in which the input / output devices 4 are arranged is operated (on-line state), the created screen and the state of the site are displayed on the display 35 to function as a monitor for monitoring the operation status of the target system. And the input / output devices 4 in the target system are controlled. At this time, the computer device 3
Executes the user program created by the ladder editor 32a and stored in the ladder file 33a according to the control function program. On the other hand, the computer device 3 functions as an editor device for creating a user program or a user screen by activating the ladder editor 32a or the drawing editor 32b when the target system is not operating (off-line state).

Here, a procedure for creating a user program and a user screen in the first to third display / control systems will be described with reference to the flowcharts of FIGS.

As shown in FIG. 10, it is determined in advance whether a user screen is created (drawn) or a user program is created (programming) according to an input operation by the user (S11). When a user program is created first, a programming process (1) using the ladder editor 32a is executed (S12), and then the drawing editor 32
The image forming process (2) using b is executed (S13). On the other hand, when creating a user screen first, the drawing editor 3
The image forming process (1) using 2b is executed (S14), and then the programming process (2) using the ladder editor 32a is executed (S15).

Next, the created user program and user screen are stored in a predetermined storage location so as to be usable (S16). At this time, the first or second display /
In the control system, the user program and the user screen are temporarily stored in the data file 33, then downloaded to the PLC 2 and the programmable display 1, respectively, and stored in the memory. Alternatively, in the second display / control system, the user program and the user screen are temporarily stored in the data file 33, downloaded to the programmable display 1, and stored in the memory unit 12. In the third display / control system, the user program and the user screen is store in the data file 33.

In the above example, the procedure of executing either the drawing or the programming first and then executing 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 processing (1) is executed first, the procedure shown in the flowchart of FIG. 11 is followed. Here, a ladder editor 32a and a drawing editor 32b are activated in the computer device 3, and an editor screen (first editor screen) for creating a user screen is displayed on a display unit 35a (see FIG. 15A) of the display 35. ) 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.

[0094] 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 such as a name and an address used for the described ladder instruction is input (S22), and the ladder symbol and the attribute data are registered in a temporary file (S2).
3). 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.
(S25).

In the subsequent drawing (2),
According to the procedure shown in the flowchart of FIG.

First, the attribute data of the ladder symbol (ladder command) registered in the ladder file 33a is imported into the screen file 33b (S31). Ladder symbol on the ladder window 32a ₁ is judged whether or not dragged by the mouse (S32), if it is dragged, it is determined whether the ladder symbol is dragged is dropped on drawing window 32 b ₁ ( S33). Here, the drop of the ladder symbol is confirmed, based on the functionality included in the attribute data for the ladder symbol is dragged, the dialog box D ₁ (FIG. 15 (c) references including a plurality of marks having the function ) Is displayed (S34).

In the above procedure, the attribute data of all the ladder symbols created by the ladder editor 32a is
The data is collectively copied to the screen file 33b in advance by the import in S31. However, instead of this, the attribute data for one ladder symbol may be imported sequentially for each drag and drop. In particular, when creating a ladder diagram that contains a large number of ladder symbols, you can import attribute data all at once,
Processing efficiency can be improved. On the other hand, when creating a ladder diagram including a small number of ladder symbols, even if attribute data is sequentially imported, there is almost no reduction in processing efficiency. Therefore, it is desirable to select which import to use based on the size of the ladder diagram and other factors.

[0098] After that, when one mark from a plurality of marks that are displayed in the dialog box D ₁ is selected, and registers the mark to a temporary file (S35).
Then, it is determined whether or not to end the drawing process according to the operation of the user (S36). Here, if not to end, S
On the other hand, when the processing is to be terminated, the created user screen is registered in the screen file 33b (S37).

Here, a specific example of the drawing processing (2) performed according to the procedure of the flowchart of FIG. 12 will be described.

[0100] First, as shown in FIG. 15 (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, the ladder file 33a registers data on switches and lamps as shown in FIG. Specifically, for the switch, “SW1” as a name and “XB0001” as an address
Is registered at least. For the lamp, at least "LAMP1" as a name and "YB0001" as an address are registered.

In this state, as shown in FIG.
Keep open the drawing window 32b _1. Further, FIG.
When the ladder symbol L in the ladder window 32a ₁ as shown in (b) is dropped after being dragged to drawing window 32 b _1, as shown in FIG. 15 (c),
Dialog box D ₁ is displayed in the drawing window 32b _1.

As described above, the attribute data of all the ladder symbols created by the ladder editor 32a is collectively copied in advance to the screen file 33b by importing. Alternatively, attribute data for one ladder symbol is imported for each drag and drop. This import is realized by temporarily storing the attribute data on the clipboard CB and then copying it to the screen file 33b as shown in FIG.

[0103] 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. 15 (d), drawing an image M of marks selected is displayed on the window 32 b _1, a dialog box D ₂ containing the attribute data (name "SW1" and the characteristic "oN") is displayed. Here, when the OK button is clicked, the mark M and attribute data on the drawing window 32b ₁ is confirmed, the graphic data file section 33b of the screen file 33b
₁ and the attribute data file section 33b _2, graphic data and attribute data are stored in association for the mark M of the switch (see Figure 16).

Therefore, the user can select the drawing window 3
2b ₁ on it is not necessary to perform the work of inputting the tasks and the required attribute data for drawing a mark switch, it can be created very easily the user screen.

On the other hand, when the drawing processing (1) is executed first, the procedure shown in the flowchart of FIG. 13 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. 17 (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.

[0106] 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 such as a name and an address used for the arranged mark are inputted (S42), and the mark and the attribute data are registered in a temporary file (S43). Thereafter, it is determined whether or not to end the drawing process according to the operation of the user (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 screen file 33b (S45).

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

First, the attribute data of the marks registered in the screen file 33b is previously stored in the ladder file 33.
a (S51). Drawing window 32b
It is determined whether the mark on ₁ has been dragged (S5).
2), when it is dragged, to determine whether a mark has been dragged is dropped on the ladder window 32a ₁ (S53). Here, if the drop of the mark is confirmed, the above attribute data is displayed together with the ladder symbol corresponding to the function based on the function included in the attribute data of the dragged mark (S54).

In the above procedure, the attribute data for all the marks arranged by the drawing editor 32b is
Ladder file 3 by import at 51
3a. However, instead of this, 1
Attribute data for one mark may be imported sequentially for each drag and drop.

Then, the displayed ladder symbol is registered in a temporary file (S55). Then, it is determined whether or not to end the programming process according to a user operation (S56). Here, if the processing is not to be ended, the process returns to S51, while if the processing is to be ended, the created user program is registered in the ladder file 33a (S57).

Here, a specific example of the programming process (2) performed according to the procedure of the flowchart of FIG. 14 will be described.

[0112] First, as shown in FIG. 17 (a), on the drawing window 32 b ₁ has already been marked M is disposed and drawing representing a switch (input) by the screen editor 32b. Accordingly, the screen file 33b is
As shown in FIG. 8, data on the switch is registered. Specifically, at least “SW1” as a name and “XB0001” as an address are registered for the switch.

In this state, as shown in FIG.
Keep open the ladder window 32a _1. Further, FIG.
7 the mark M in the drawing window 32 b ₁ as shown in (b) is dropped after being dragged to the ladder window 32a _1, as shown in FIG. 17 (c), the ladder symbol L and dialog boxes D ₃ Ladder It is displayed in the window 32a _1.

As described above, the attribute data of all the marks arranged by the drawing editor 32b are collectively copied to the ladder file 33a by import in advance. Alternatively, attribute data for one mark is imported for each drag and drop.
This import is realized by temporarily storing the attribute data on the clipboard CB and then copying it to the ladder file 33a as shown in FIG.

[0115] Then, as shown in FIG. 17 (c), together with the ladder symbol L is drawn on the ladder window 32a ₁ corresponding to the switch function, the attribute data (name "S
W1 ") dialog box D ₃ including displayed.
Here, when the OK button is clicked, the ladder symbol L and the attribute data on the ladder window 32a ₁ is confirmed, the command file section 33a of the ladder file 33a
₁ and the attribute data file section 33a _2, the command and attribute data is stored in association for the ladder symbol L of the switch (see Figure 18).

[0116] 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.

As described above, in the first to third display / control systems according to the present embodiment, the ladder editor 3
A ladder file 33a for storing the user program created in 2a, and a screen file 33b for storing the user screen created in the drawing editor 32b,
The copy function unit 32d is configured to copy the attribute data of the ladder symbol to the screen file 33b and to copy the attribute data of the mark to the ladder file 33a. As a result, both files 33a and 33b can have attribute data common to both files 33a and 33b.
Attribute data between 33b can be easily associated.

Further, by having independent databases for the user program and the user screen as described above, the above-described attribute data can be copied between each database and another database. Specifically, a database using general-purpose application software (spreadsheet software, etc.), a database for electronic circuit CAD, a database created by software for G code programming (machining programming) of the NC control device, and the like. Is selected as an image block by inputting data or the like on the operation input screen of the software, and the data is copied to the user program or the user screen database by dragging and dropping (or copying and pasting) as described above. I do.

In particular, when designing a control panel using CAD software (CAD software), it is effective to exchange data with a ladder editor and a drawing editor.

To develop any equipment system, an electrical system diagram including a mechanical design diagram is required.
In addition, in order to create an electrical system diagram, it is necessary to create an electrical specification, a control panel diagram, a parts list, and a hardware diagram (such as a circuit diagram). Then, based on the created electrical system diagram, a control panel is manufactured, and electrical work of an apparatus system in which the control panel is installed is advanced. Also,
In the process of designing and manufacturing a control panel, specifications are firstly agreed upon, and CAD is performed based on the specifications.
Using a tool for creating a drawing such as software, the electrical configuration is designed, and then a transition is made to the creation of a display / control system program including a PLC or the like. At this time, by using the function of the copy function unit 32d according to the present embodiment,
Data input by CAD software can be used to create a user program and a user screen.

Specifically, the application 32c of the computer device 3 (see FIGS. 1, 7 and 9)
When the D software is installed, the CAD software is started, and as shown in FIG.
To display the AD window 32c ₁ and the ladder window 32a _1. The CAD window 32c _1, PLC
Push button switch (graphic symbol name P
B001) and a pilot lamp (represented by the symbolic name PL001) connected to the output of the PLC. In this state, the CAD window 32
Drag graphical symbols (image blocks) of the push button switch displayed on c _1, and the ladder window 32a ₁
, The ladder symbol L ₁ (LD instruction or the like) corresponding to the push button switch is displayed in the ladder window 32 in substantially the same procedure as the procedure shown in the flowchart of FIG.
It is displayed on a _1. Similarly, the pilot lamp also has a ladder symbol L ₂ (OUT command) as the ladder window 32a.
Displayed in ₁ .

On the other hand, when a user screen is created using CAD data, as shown in FIG.
5a, CAD window 32c ₁ and drawing window 3
2b ₁ is displayed. In this state, by dragging the symbol of the push button switch displayed on the CAD window 32c ₁ and dropping it on the drawing window 32b ₁ , the procedure shown in the flowchart of FIG. the corresponding mark M is displayed in the drawing window 32b _1. At this time, if by sharing the function of the button switch and pilot lamp press between an output portion input of the PLC, the mark M, which also serves as a pushbutton switch and pilot lamp is displayed on the drawing window 32 b _1.

The data to be imported into the ladder file 33a and the drawing file 33b at the time of the above processing are as follows:
As shown in FIG. 20, the application file 33c
Is stored in a CAD database constructed at the same time. Specifically, a symbol name, a comment, a PLC-related address, and the like are stored. PLC related address is PLC2
The address is assigned to a device such as a push button switch or a pilot lamp connected to the device. The figure symbol name is a symbol name given to a push button switch, a pilot lamp, or the like in the above-described figures created by CAD software. This graphic symbol name is associated with the above address, and is set to be the same as a variable used instead of an address when assigning an address such as a push button switch or a pilot lamp to a ladder symbol or mark. The comment is provided to indicate an operation state or the like of the device.

In the CAD database, by setting the symbol names and variables to be the same, the symbol names (names) and the PLC-related addresses (addresses) are attributed to the attribute data (FIGS. 6A and 6B). See). Thus, the ladder editor 32a and the drawing editor 32b display the graphic symbol names as variables together with the ladder symbols L ₁ and L ₂ and the mark M. Also,
The drawing editor 32b displays a comment “driving” on the mark M.

Here, in the third display / control system,
As shown in FIG. 9, since the computer device 3 having the editor function and the PLC function is connected to the open network 8, the database in the computer device 3 and the other systems A to Attribute data on ladder symbols and marks can be exchanged with a database such as C via a network. In addition, the same database can be shared between the computer device 3 and a remote system via a network.

Also in the second display / control system, if the programmable display 1 has an interface connectable to the open network 8, the programmable display 1 is connected to the open network 8 as shown in FIG. Computer device 3 or other system A via
To C or the like. In addition, the first display /
In the case of a control system, the programmable display 1 can be connected to the open network 8 in the same manner as in the second display / control system.
In the communication between the PLC 2 and the PLC 2, it is necessary to support different communication protocols for each manufacturer of the PLC 2. For this reason,
As described in Japanese Patent Application No. 10-117117 previously filed by the present applicant, a common communication protocol used for communication on the open network 8 and a communication protocol corresponding to the model of the PLC 2 are mutually exchanged. A function for conversion is provided in the programmable display 1.

In addition, when a plurality of user screens having different patterns are created for one user program,
Even when a plurality of PLCs 2 are connected to one programmable display 1 in the first display / control system, a link between one-to-many databases can be easily realized by copying data between databases.

Further, in the present embodiment, an example has been described in which the ladder window and the drawing window are displayed on the same display. However, the ladder window and the drawing window are displayed based on databases of different devices via a network. In this case, the present invention can be applied.

More specifically, as shown in FIG.
A database DB ₁ storing the user program downloaded to the PLC 2 in the first display / control system, and a database DB storing the user screen downloaded to the programmable display 1 in the second display / control system Data is exchanged between the _two . In this case, in the computer device 3, as shown in FIG.
a user program in the database DB ₁ which is displayed on a _1, drag between the user screen in the database DB ₂ to be displayed on the drawing window 32 b ₁ &
Ladder symbols and marks can be automatically generated by dropping. Therefore, editing and correction can be easily performed between the user program already downloaded to the PLC 2 and the user screen downloaded to the programmable display 1.

Note that 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.
