Technical field

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a program creation support apparatus constructed by a programming and storage medium using a function block diagram and a program execution apparatus executed by a program creation support apparatus.

Conventional technology

Function block diagram (FBD) is a graphic programming language of the "IEC61131-3 standard" by the International Electrotechnical Commission. The program of the FBD is displayed as a series of block diagrams in which blocks such as a function or a function block FB are connected to each other. Each function block has an input terminal on the left side of the function block and an output terminal on the right side, and the function blocks are determined through input terminals or output terminals (function and function blocks are defined in IEC61131-3 ''. to be).

Fig. 41 is a block diagram showing a simple function and a function block, and shows an "N0T" function NOT as an example. In Fig. 41, the data value supplied from the input terminal IN is subjected to a predetermined process, and is supplied from the output terminal 0UT to an external element (not shown) as the value of the processing result. In this case, the "NOT" function inverts the BOOL type data value supplied from the input terminal IN and supplies the inverted result value to the external element from the output terminal OUT.

42 is a block diagram showing a function or a function block FB for performing a complicated process. In Fig. 42, the function or function block requires a parameter value to be used inside the process in addition to the value of the input terminal IN to be processed, so that the parameter input terminal PARAM for supplying the parameter value is provided. It is prepared.

On the other hand, FIG. 43 is a block diagram showing FB in the case where designation is made in a dialog box without providing a parameter input terminal PARAM.

In FIG. 43, when the function block FB is double-clicked with a mouse, a dialog is displayed. Therefore, when the parameter value is set on the dialog and the "OK" button is pressed, the process is performed with the value of the setting parameter. .

In the case of using the dialog system of FIG. 43, an operation of deliberately displaying a dialog and inputting a value is necessary to set parameters even for a function or function block having a relatively small number of input terminals. In addition, on the function block diagram (FBD) which is the created program, it is impossible to see what value is set in the parameter.

Therefore, in the case of a relatively simple function or function block, the method of providing the parameter input terminal PARAM as shown in Fig. 42 is preferable in terms of readability of the created program in terms of work efficiency of program creation.

However, when the method of Fig. 42 is used for a complicated function or a function block FB having a large number of input terminals, the FB becomes large because a large number of input terminals need to be provided in the FB, and one FB is a program creation area. The area ratio occupied by the chip becomes large, which interrupts the work of writing the program. Moreover, since it is necessary to connect all the many input terminals provided in FB, wiring becomes complicated and the readability of the created program also worsens.

Therefore, in the case of a complex FB, as shown in FIG. 43, the method of setting a parameter to a dialog box and not providing a parameter input terminal is that of the program readability also in terms of work efficiency of program creation. Also becomes preferable.

As a form of a function or a function block (FB), whichever is shown in FIG. 42 or 43 is used by a program creation support device or a program creation support device configured by a programming and storage medium using a function block diagram. The side which provides the program execution apparatus which executes the created and coded program should just examine the said process content, and may decide suitably.

In a program creation support device (programming method), a program execution device, and a storage medium using a conventional function block diagram (FBD), a process frequently used in a program is defined in advance, thereby creating an FBD program. The user-defined FB function which shortened the time is implemented (for example, refer patent document 1).

Fig. 44 is a block diagram showing a conventional apparatus in a flow chart, and shows operation procedures related to a FB prepared in advance, a user defined FB editing region, a user defined FB, and an FBD program editing region (see dashed line). It shows in step S31-S34 (refer the broken line).

In Fig. 44, when a user-defined FB is created by combining a function or a function block FB prepared in advance with a programming tool (step S31), the user-defined FB created and defined by the user is registered as a function block (step). S32).

Therefore, similar to the FB prepared in advance, the user-defined FB can be used in another program as a function block (step S33). At this time, the content edited in step S31 is executed in the process of user defined FB.

The user defined FB encapsulates a specific process in the form of a function block, and when using the user defined FB as a program (step S33), it is only necessary to know the processing contents of the encapsulated user defined FB. It is not necessary to know which FBD is described (step S31).

In addition, since the user-defined FB in which the processing contents are encapsulated is in an executable state in which there is no error in the program description, when the user-defined FB is used (step S33), it is determined whether there is an error in the description of the processing contents. Since there is no need to worry, the creation time of the FBD program is shortened.

In addition, since the processing contents encapsulated in the form of user-defined FB are not shown to the side using the user-defined FB, the know-how of the program describing the processing contents can be concealed.

In addition, in the programming method using the conventional function block diagram, its apparatus, and the storage medium, functions for restricting the access level to the edited content of the user-defined FB by the user are also executed.

However, in the conventional apparatus, since there is no means for setting the parameters used in the internal processing of the user-defined FB to the dialog system shown in Fig. 43, the functions and function blocks used in the description of the internal processing of the user-defined FB ( In the case of using the parameters used in the internal processing of FB) and the parameter input terminal method of FIG. 42, it is necessary to make each parameter an input terminal of the user-defined FB as shown in FIG.

As a result, as described above, in the case of a complex FB, a problem arises in the user-defined FB that disturbs the program creation work.

In addition, if all the parameters used in the functions used for the internal processing of the user-defined FB and the functions used in the internal processing of the function block are provided as input terminals of the user-defined FB, the user-defined FB becomes larger, which is not preferable. .

When the parameters used in the functions used in the internal processing of the user-defined FB and the internal processing of the function block are in the form shown in Fig. 43 (dialog box designation method), as shown in Fig. 46, the user The processing of the positive FB operates at the parameter set values, and each parameter cannot be changed when using the user defined FB.

Therefore, if you want to use the user-defined FB as the value of another parameter, you need to create and register the user-defined FB as many as the number of other parameters. Shortening the creation time cannot be realized.

Patent Document 1: Japanese Patent Application Laid-Open No. 2003-223204

In the conventional program creation support device and the program execution device, there is no means for setting the parameters used in the internal processing of the user-defined FB in a dialog manner. There is a problem that the workload increases and the user-defined FB becomes huge.

In addition, if the parameters used in the function used for the internal processing of the user defined FB or the function processing of the function block were the dialog system, each parameter cannot be changed when using the user defined FB. When it is desired to use it, it is necessary to create and register a user defined FB as many as the number of other parameter settings, and there is a problem that a shorter time for FBD program creation, which is the purpose of the user defined FB function, cannot be realized.

This invention is made | formed in order to solve the said subject in user defined FB, Even if it is a complicated FB by realizing the means to provide the dialog for setting the parameter used in the internal process of user defined FB in a dialog system. It is an object of the present invention to obtain a program execution support device that executes a coded program created by a program creation support device and a program creation support device, which avoids an increase in workload and a huge user-defined FB.

Means to solve the problem

User defined FB parameter setting means for setting the FB parameter, and user defined FB parameter setting value storing means for storing the user defined FB parameter setting value set by the user defined FB parameter setting means; Saves user-defined FB parameter settings The user-defined FB is encoded by the parameters stored in the means.

In addition, the program execution apparatus according to the present invention combines program instructions including a predefined user defined FB to generate user defined FB creation means and user defined FB processing execution code for defining a new function or function block. In order to execute a program created and coded by the program creation support apparatus having the means, the code generated from the user defined FB process execution code generating means is executed.

According to the present invention, parameters related to the processing contents of the user defined FB including the parameters of the FB used in the description of the internal processing of the user defined FB can be set from the user defined FB, so that the program creation time can be set. Can be shortened.

3 is a block diagram schematically showing a program creation device 1 for realizing a program creation support device and a program execution device according to Embodiment 1 of the present invention.

In FIG. 3, the program generating apparatus 1 is realized by a microcomputer having a man machine interface (see FIG. 1), the tree view 2, the FB area 3, and the user-defined FB area 4. ), An FBD program editing area 5, and a user-defined FB editing area 6.

In the tree view 2, a program created by a user and a user-defined FB are hierarchically displayed using the program creation device 1. In the FB area 3, the FB prepared in advance by the side which provides the program creation apparatus 1 is displayed, and the user-defined FB (user defined FB) is displayed in the user-defined FB area 4. In the FBD program editing area 5, a normal program is created, and in the user defined FB editing area 6, a user defined FB is edited.

Hereinafter, the basic operation regarding a normal program is demonstrated.

In Fig. 3, for example, when the user double-clicks the program α in the tree view 2 with a mouse, the program editing area 5 is displayed, and the contents of the program α can be edited.

As a specific editing procedure of the program α, for example, a desired FB is selected from the FB (preliminarily prepared FB) in the FB area 3, and the mouse is moved to the FBD program editing area 5 with a mouse (drag). By adding a FB to the program.

In addition, the user can perform a desired edit by wiring the input terminal or the output terminal of the FB arranged on the program with a mouse. In addition, when a program is newly added, a new program addition instruction or the like is issued from the pop-up menu displayed by right-clicking on the program in the tree view 2.

Next, operations related to the user-defined FB (hereinafter also referred to as "user FB") will be described.

In Fig. 3, for example, when a user double-clicks the user FB (α) in the tree view 2 with a mouse, the user defined FB editing area 6 is displayed, and the contents of the user FB (α) can be edited. It becomes a state.

For a specific editing procedure of the user defined FB, for example, the desired FB is selected from the FB (prepared FB) in the FB area 3, and the mouse is moved to the user defined FB edit area 6 (drag & drag). Drop), as in normal program editing in which an FB is added to a program. In addition, when a user-defined FB is newly added, an additional instruction or the like of the new user-defined FB is issued from the pop-up menu displayed by right-clicking on the user-defined FB in the tree view 2.

The user-defined FB created in this way is displayed hierarchically in the tree view 2 and is also displayed in the user-defined FB area 4.

When editing a program, it is similar to adding an FB to a program by dragging and dropping a mouse to select a desired FB (prepared FB) from the FB area 3 and moving the mouse to the program editing area 5. The user-defined FB is added to the program by dragging and dropping the desired user-defined FB from the user-defined FB area 4 and moving the mouse to the program editing area 5 with the mouse.

Next, the parameter setting procedure according to Embodiment 1 of the present invention shown in Figs. 1 to 3 will be described with reference to the explanatory diagrams of Figs. 5 and 6 related to Fig. 3 together with the flowchart of Fig. 4. do. In addition, in FIG.5 and FIG.6, only the area part directly related to an operation procedure is shown. In the dialogs shown in the drawings, the elements of the dialog that can be input are displayed in white blocks by inputting a string, checking a check mark, selecting a desired value from the list, and reading a character string display or a button. The elements of the dedicated dialog are shown in gray blocks.

In FIG. 4, the operation procedure which sets the parameter at the time of using a user-defined FB in a program is shown by using the parameter setting dialog of the FB used for description of the internal processing of a user-defined FB directly from a user-defined FB. .

In FIG. 4, step S1 and S2 at the time of creating user FB, and step S3 at the time of using user FB respond | correspond to the basic operation regarding the above-mentioned normal program.

In this case, it is assumed that the user FB (β) as shown in the user defined FB area 4 in FIG. 5 is created in steps S1 and S2 (when creating a user FB). In addition, FB (φ) is described in user FB (β), and it is assumed that it has a parameter value PARAMφ (user defined FB parameter set value).

First, at the time of user FB creation, the user FB is newly added (step S1), the user FB is edited (step S2), and the user FB (β) as shown in Fig. 5 is created.

In subsequent use of the user FB, as shown in Fig. 6, first, the user FB (β) is placed in the program (step S3).

Subsequently, by double-clicking the user-defined FB placed in the program with a mouse, the parameter setting dialog of the FB (φ) used for the description of the internal processing of the user FB (β) created in steps S1 and S2 is directly displayed. , Inputs and sets the parameter value PARAMφ of the internal processing of FB (φ) (step S4).

The parameter value PARAMφ input in step S4 is set in the user defined FB parameter set value storage means 302 of the user FB (β).

Finally, the coding of the user defined FB is executed based on the value of PARAMφ (step S5), and the operation procedure of FIG. 4 ends.

At this time, the parameter setting dialog of the FB used for the description of the internal processing is displayed as the parameter setting dialog of the user defined FB, thereby functioning as the user defined FB parameter setting means 301.

In addition, in step S1 and S2, since the user FB ((beta)) as shown to the user-defined FB area | region 4 in FIG. 5 was created, in step S4 at the time of user FB creation, from user-defined FB area | region 4 Drag and drop of the user FB (β) to the FBD program editing area 5 results in a state as shown in the FBD program editing area 5 in FIG.

In the FBD program editing area 5, the parameter value PARAMφ of the internal processing of the unit FB (β) is set.

In step 4, the user defined FB parameter set value storage means 302 also functions, and the value of the parameter PARAMφ set in step S4 is stored as a parameter of the user FB (β).

In step S5, the code which performs the process of the said user defined FB is produced | generated using the parameter setting value PARAMphi of the parameter stored by the user defined FB parameter setting value storage means 302. FIG. In step S5, the user defined FB process execution code generation means 305 functions, and the process of the user FB is executed based on the parameter value PARAMφ set thereby.

Next, a method of generating code will be described in detail.

First, when the parameter value of the user FB (β) (see Figs. 5 and 6) is not set, code generation similar to the conventional user defined FB is executed. That is, the program described in the FBD program editing area 5 is coded, and the internal processing of the user FB (β) which is the program described in the user defined FB editing area 6 is also coded.

Subsequently, when the user FB (β) is executed in the program execution device that executes the coded program, the coding of the internal processing described in the user-defined FB editing area 6 is executed. Therefore, the user FB (β) is executed by the parameter value PARAMφ set when the user-defined FB editing area 6 is described.

Next, the case where the parameter value PARAMφ of the user FB (β) is set will be described.

In this case, when coding the program described in the FBD program editing area 5, the coding of the user FB (β) is coded by the parameters stored in the user-defined FB parameter setting value storage means 302. .

Subsequently, when executing the user FB (β), the program execution device executing the coded program reflects the parameter value PARAMφ and executes the coded internal processing described in the user defined FB editing area 6. do. Therefore, the user FB (β) is executed by the parameter value PARAMφ set by the user defined FB parameter setting means 301 and stored in the user defined FB parameter set value storage means 302.

As described above, the program creation support apparatus according to the first embodiment of the present invention combines program instructions including a user-defined FB that is predefined to define user-defined FB creation means for defining a new function or function block ( 303) and a program having a user-defined FB processing execution code generation step 305 (step S5) for encoding a user-defined FB portion in encoding for executing a program described by using the user-defined FB in a program execution device. In the creation support apparatus, the user defined FB parameter setting means 301 (step S4) for setting the user defined FB parameter of the user defined FB and the user defined FB parameter setting value set by the user defined FB parameter setting means 301. The user-defined FB parameter setting value storage means 302 (step S4) to save is provided.

The user-defined FB process execution code generation means 305 codes the user-defined FB by the parameter stored in the user-defined FB parameter setting value storage means 302, and the user-defined FB parameter setting means 301 defines the user definition. The FB parameter setting means 304 of the FB used for the description of the internal processing of the FB is displayed, and the user-defined FB parameter setting value storing means 302 stores the parameter setting value set by the FB parameter setting means.

In addition, the program execution device according to the first embodiment of the present invention includes a user-defined FB creating means 303 for defining a new function or a function block by combining a program instruction including a predefined user-defined FB. To a program creation support apparatus having user defined FB processing execution code generating means 305 (step S5) for encoding a user defined FB portion in encoding for executing a program described by using the user defined FB in a program execution apparatus. In order to execute the program created and coded, the code generated from the user defined FB processing execution code generating means 305 is executed.

Thus, by realizing the means for providing a dialog for setting the parameters used in the internal processing of the user defined FB in a dialog manner, even in the case of a complicated FB, an increase in the workload and a large user defined FB are avoided, and the FBD A program creation support device and a program execution device can be obtained which have reduced the program creation time.

In coding the program described in the FBD program editing area 5, the coding of the user FB (β) is coded by the parameters stored in the user-defined FB parameter setting value storage means 302.

Embodiment 4

Further, in the first to third embodiments, the FB used in the description of the internal processing of the user-defined FB is set in order to set all the parameters of the FB used in the description of the internal processing of the user-defined FB from the user-defined FB. As the parameter setting dialog, a dialog of the user-defined FB was provided directly from the user-defined FB.

However, when the internal processing of the user defined FB is described, when the parameter is set in the parameter setting dialog of the FB, and there are parameters that are always desired to be fixed when the user defined FB is used, the parameter setting dialog is defined from the user defined FB. It is preferable not to extract.

EMBODIMENT OF THE INVENTION Hereinafter, Embodiment 4 of this invention for achieving the said objective is demonstrated, referring FIGS. 13-17.

In addition, the structure of the program creation support apparatus and program execution apparatus which concerns on Embodiment 4 of this invention is as showing in FIG.

FIG. 13 is a block diagram showing the functional configuration of Embodiment 4 of the present invention, and the same reference numerals as those described above are omitted for the same descriptions as those described above (see FIG. 9). In this case, the user defined FB creation means 303 further includes an FB parameter setting means designation means 307, and the FB parameter setting means designation means 307 is an FB in the user defined FB parameter setting means 301. Associated with the parameter setting means selection means 306.

The structure for enabling designation is shown.

In FIG. 14, in addition to the above-described configuration (see FIG. 3), the program generating device 1 includes an FB parameter setting means designation means 99 corresponding to the FB parameter setting means designation means 307.

In Fig. 15, the parameter setting dialog of the FB used in the description of the internal processing of the user-defined FB is specified directly from the user-defined FB, and the parameter setting dialog of the designated FB is directly used from the user-defined FB. By using, the operation procedure for setting the parameter when using a user defined FB in a program is shown.

In FIG. 15, steps S1 to S5 are the same operations as those described above (see FIG. 10), and differ from the above in that step S6 is added after step S2 at the time of user FB creation.

It is explanatory drawing which shows the state for specifying that it can use directly from a user-defined FB. 17 is explanatory drawing which shows the state after the operation by step S4A in FIG. 15, and respond | corresponds to FIG. 12 mentioned above.

The FB parameter setting means designation means 99 in FIG. 14 issues FB parameter setting means designation instructions from the pop-up menu displayed by right-clicking on the user FB γ in the tree view 2 or edits user-defined FB. It is displayed by giving the FB parameter setting means designation instruction from the pop-up menu displayed by right-clicking on the blank area on the area 6.

Thereby, in the FB (γ) parameter setting means designation means 99, it is possible to designate what is used as the user defined FB parameter setting means 301 among the parameter setting means of the plurality of FBs described in the internal processing of the user defined FB. .

In Embodiment 4 of the present invention, similarly to Embodiment 3 described above, it is assumed that a user FB (γ) (see FIG. 11) is created in Steps S1 and S2. In addition, FB (phi) and FB (psi) are described in user FB (gamma), and it is assumed that FB (phi) and FB (psi) have parameter values PARAMphi and PARAMψ, respectively.

In FIG. 15, following the step S2 at the time of user FB creation, the FB parameter setting means designation means 99 (refer to FIG. 14) is displayed by the mouse right click, and the parameters of the FB to be used as the parameter setting dialog of the user FB. Specify the setting dialog (step S6).

At this time, in step S6, in the FB parameter setting means designation means 99, the names of the FBs having the parameter setting dialog among the FBs used for the description of the internal processing of the user-defined FB are displayed in a list. In addition, as shown in Fig. 16, the FB parameter setting means designation means 99 displays a check box for designating whether or not the parameter setting dialog can be directly used from the user-defined FB. By this, only the parameter setting dialog of FB (phi) shall be designated so that it can also be used directly from a user defined FB.

Since the user FB (gamma) as shown to the user defined FB area | region 4 in FIG. 11 was created in step S1, S2, in step S3 following step S6, as described above, the user FB (gamma) is programmed. It shall be arranged in.

Subsequently, in step S4A, the user-defined FB placed in the program is displayed from the pop-up menu displayed by right-clicking the mouse, or from the dialog displayed by double-clicking the mouse. The list of dialogs specified in step S3 in the parameter setting dialog of FB (φ) or FB (ψ) used in the description of the process is displayed and one of them is selected.

In step S4B, the dialog selected in step S4A is displayed, and the parameter value PARAMφ is input. The input value at this time is set in the parameter storage means of the user FB (γ). Finally, in step S5, the user-defined FB is executed based on the input value, and the operation procedure of FIG. 15 ends.

In this case, in step S6 at the time of creating the user FB, as shown in Fig. 16, a check box is checked in order to specify that the parameter setting dialog of FB (φ) can be directly used from the user-defined FB. In step S4A, the state is as shown in FIG. 17.

In FIG. 17, the state which selects the dialog which sets the parameter value of the internal process of user FB ((gamma)), and sets the parameter value PARAM (phi) of internal process of FB ((phi)) is shown.

As described above, according to the fourth embodiment of the present invention, the user-defined FB creating means 303 further includes the FB parameter setting means specifying means 307 (FB parameter setting means specifying means 99) (step S6). In the case where a plurality of FB parameter setting means 304 of the FB is provided and used for the description of the internal processing of the user defined FB, among the plurality of FB parameter setting means 304, the user-defined FB parameter setting means 301 Specify the FB parameter setting means to be used as a function. In addition, the FB parameter setting means selection means 306 (step S4A) displays only the FB parameter setting means 301 designated by the FB parameter setting means designation means 307 among the plurality of FB parameter setting means 304. .

Thus, by using the FB parameter setting dialog directly used by the user-defined FB in describing the internal processing of the user-defined FB, the user-defined FB dialog is provided and the internal processing of the user-defined FB is described when describing the internal processing of the user-defined FB. When using a user-defined FB by setting in the parameter setting dialog, if there is a parameter that you want to always have a fixed value, the parameter setting dialog can not be extracted from the user-defined FB.

Embodiment 5

In the first to fourth embodiments, the parameters of the FB are described when describing the internal processing of the user-defined FB in order to set all the parameters of the FB used in the description of the internal processing of the user-defined FB from the user-defined FB. If there is a parameter to be set in the setting dialog and the user-defined FB always wants to be classified, specify whether to use the parameter setting dialog of the corresponding parameter FB directly from the user-defined FB. For this purpose, the dialog of the user defined FB was provided by directly using the parameter setting dialog of the FB used in the description of the internal processing of the user defined FB directly from the user defined FB.

However, given the nature of user-defined FBs that encapsulate specific processing in the form of FBs (function blocks), only the parameters that you want to be variable when using user-defined FBs can be set from the dialog of user-defined FBs. The other parameters are preferably set in the parameter setting dialog of the FB when describing the internal processing of the user defined FB, and always set to a fixed value when using the user defined FB.

For example, in the case where two or more parameters are set in the parameter setting dialog of one FB, some of the parameters are fixed and other parameters can be set from the user-defined FB dialog. In Embodiments 1 to 4, this cannot be realized.

Therefore, it is preferable not to specify whether to use each of the parameter setting dialogs of the FB (see Embodiment 4 above) but to specify whether each of the individual parameters is variable.

Hereinafter, with reference to FIGS. 18-23, Embodiment 5 of this invention provided the user defined FB parameter setting means creation means which produces the dialog of a user defined FB in order to achieve the said objective.

In addition, the structure of the program creation support apparatus and program execution apparatus which concerns on Embodiment 5 of this invention is as showing in FIG.

FIG. 18 is a block diagram showing the functional configuration of Embodiment 5 of the present invention, and the same reference numerals as those described above are omitted for the same descriptions as those described above (see FIGS. 2, 9, and 13), and detailed description thereof is omitted. do. In this case, the user defined FB parameter setting means 303 includes user defined FB parameter setting means creation means 308 associated with the user defined FB parameter setting means 301 instead of the FB parameter setting means designation means 307. Doing.

The user defined FB parameter setting means creation means 308 has a parameter acquisition means 309 and a parameter association setting means 310, and the parameter acquisition means 309 is configured to process the contents of the user defined FB (internal processing). Gets the parameters related to FB processing used in the description). In addition, the parameter association setting unit 310 associates each parameter setting element of the created user-defined FB parameter setting unit 301 with a parameter acquired by the parameter obtaining unit 309.

19 is a block diagram schematically showing a fifth embodiment of the present invention, and the same reference numerals as those described above are attached to the same ones described above (see FIGS. 3 and 14).

In FIG. 19, the program creation device 1 is for editing a user-defined FB dialog that displays a user-defined FB dialog editing area 7 and GUI (Graphical User Interface: Graphical User Interface) components for editing a user-defined FB dialog. The GUI component area 8 is provided.

The user defined FB dialog editing area 7 and the user defined FB dialog editing GUI part area 8 are user defined FB parameter setting means creating means 308 for creating a user defined FB parameter setting means 301 by a user. ). Thereby, a user can create the dialog which sets the parameter of the created user defined FB.

Next, with reference to the explanatory drawing of FIG. 21 with the flowchart of FIG. 20, operation procedure (the creation of the dialog which sets the parameter of user defined FB) according to Embodiment 5 of this invention shown in FIG. The procedure up to the parameter setting when using the definition FB in a program will be described.

In FIG. 20, steps S1 to S5 are the same operations as those described above (see FIG. 4), and after step S2 at the time of user FB creation, operations corresponding to the user defined FB parameter setting means creating means 308 (step S7). , S8) is different from the above.

21 and 22 are explanatory diagrams showing the concept of steps S7 and S8. The GUI part area 8 for user defined FB dialog editing, the user defined FB dialog editing area 7, and the parameter association dialog 9 ) Is shown schematically. The parameter association dialog 9 constitutes a parameter association setting means 310. 23 is explanatory drawing which shows the state after the operation by step S4 in FIG. 20, and respond | corresponds to FIG. 12, 17 mentioned above.

Here, similarly to the second embodiment described above, in step S1 and S2 in FIG. 20, a user FB (γ) as shown in FIG. 11 is created. In the user FB (γ), FB (φ) and FB (?) is described, and FB (?) and FB (?) are assumed to have parameter values PARAM? and PARAM ?, respectively.

First, a dialog editing instruction is executed from the pop-up menu displayed by right-clicking on the user FB (γ) of the tree view 2 in FIG. 19, or right-clicking on a blank area on the user-defined FB editing area 6 to display it. By giving a dialog editing instruction from the pop-up menu, the user-defined FB dialog editing area 7 is displayed, and a dialog for the user FB is created (step S7). Thereby, the state of the dialog of user FB (gamma) can be edited.

To edit the dialog of the user defined FB, as shown in Fig. 21, the desired GUI part is selected from the GUI part area 8 for user defined FB dialog editing and moved to the user defined FB dialog edit area 7 with the mouse. Drag and drop to add a GUI to the dialog. The GUI part area 8 for user defined FB dialog editing may be a window different from the user defined FB dialog editing area 7, and a menu or a tool to be displayed on the user defined FB dialog editing area 7. It may be in the form of a bar.

Next, a parameter association dialog 9 for specifying a parameter to be associated is displayed by double-clicking a GUI component placed on the dialog in FIG. 21, and the parameter associated with the GUI component is designated. The GUI part of the dialog is associated with a parameter (step S8).

The parameter association dialog 9 displays the parameters acquired by the parameter acquisition means 309 as a list.

In FIG. 21, the state which selects the value of the parameter related to GUI component from a list is shown.

In addition, since the 0K button and the CANCEL button on the dialog of the user defined FB dialog editing area 7 are arranged on the dialog in advance, the function is also predetermined. It cannot be associated with a parameter. Further, in the parameter association dialog 9, it is possible to appropriately realize a convenient function such as which parameter belongs to which FB, and which parameters are already associated, such as displaying the name of the GUI component of the association. There is a number.

In step S7 and S8, as shown in FIG. 22, it is assumed that a dialog of the user FB (γ) is created in association with step S1 and S2. As described above, FB (φ) and FB (ψ) are described in the user FB (γ), and each has parameter values PARAMφ and PARAMψ, so that each user FB (γ) has a parameter value (PARAMφ, PARAMψ). GUI parts are arranged so that parameters can be set, and associated with each other as shown in FIG.

In FIG. 22, the drag and drop states of "Static Text" and "Edit Box" from the user defined FB dialog editing GUI part area 8 to the user defined FB dialog editing area 7 and the static text of the GUI part. To change the character string to the parameter values (PARAMφ and PARAMψ), to place the "Edit Box" of the GUI component, and to set the relation with the parameter values (PARAMφ and PARAMψ) of FB (φ) and FB (ψ). The state is shown.

Hereinafter, in step S3 at the time of using the user FB in FIG. 20, since the user FB (γ) (see FIG. 11) is created in steps S1 and S2 at the time of creating the user FB, the user FB (γ) is arranged in the program. .

In subsequent step S4, the parameter setting dialog of the user-defined FB created by step S7, S8 is displayed by double-clicking the user-defined FB arrange | positioned in a program, etc., and a parameter value is input.

The input value of the parameter is set to the parameter associated in step S8, and user defined FB is executed in step S5 based on the value. At this time, the parameter setting dialog of the user defined FB corresponds to the user defined FB parameter setting means 301.

In addition, since the dialog of the user FB (gamma) was created in step S7 (refer FIG. 22), it is in the state as shown in FIG. 23 in step S4.

In FIG. 23, the drag & drop state of the user FB (γ) from the user-defined FB area 4 to the FBD program editing area 5, and the user FB (γ) parameter setting dialog (in the FBD program editing area 5) On 10), the state of setting the parameter values PARAMφ and PARAMψ of the internal processing of the user FB (γ) is shown.

In addition, since the GUI component and the parameters are associated with each other in step S8 (see FIG. 22), when a parameter value is input into the "Edit Box" on the right side of "PARAMφ" displayed by a dialog in the user-defined FB dialog editing area 7. The input value is stored in the user-defined FB parameter set value storage means as the parameter value PARAMφ of FB (φ). Similarly, when a parameter value is input in the "Edit Box" on the right side of "PARAMψ" displayed in the dialog, the input value is stored in the user-defined FB parameter setting value storage means as the parameter value PARAMψ of FB (ψ).

Finally, in step S5, the coding process of the user FB (γ) is executed based on the set parameter value.

As described above, according to Embodiment 5 of the present invention, user-defined FB parameter setting means creation means 308 (user-defined FB dialog editing area 7) for creating user-defined FB parameter setting means 301 by a user. ), And the user defined FB dialog editing GUI component area 8, and the user defined FB parameter setting means creating means 308 includes: a parameter acquiring means for acquiring a parameter related to the processing contents of the user defined FB. 309 and parameter association setting means 310 for associating each parameter setting element (GUI component) of the created user-defined FB parameter setting means 301 with the parameters acquired by the parameter obtaining means 309.

This makes it possible to provide a dialog for setting parameters used in the internal processing of the user-defined FB, and has the same effect as described above, and the property of the user-defined FB that encapsulates a specific process in the form of a function block. Even in the case of using the user defined FB, only the parameters that are desired to be changed when the user defined FB is used can be set from the dialog of the user defined FB. When setting and using a user defined FB, it can always be set as a fixed value.

Specifically, in creating the dialog of the user FB (γ), in the example of FIG. 22, the GUI parts are arranged and related so that the parameter values of both PARAMφ and PARAMψ can be set, but the example is not limited thereto. For example, by arranging and associating a GUI component with only one side, the value of this parameter can be changed from the dialog of a user-defined FB, and the other parameter can always use a fixed value.

Embodiment 6

In the fifth embodiment, the case where the function or FB (function block) used for the description of the internal processing of the user-defined FB has a parameter setting dialog (for example, see FIG. 43) has been described. As shown in FIG. 25, it may apply to the case where it does not have a parameter setting dialog and has a parameter terminal PARAM (refer FIG. 42).

Hereinafter, the program creation support device and the program execution device according to Embodiment 6 of the present invention will be described with reference to FIGS. 24 and 25 along with FIG. 20. In addition, the functional structure of Embodiment 6 of this invention is as showing in FIG.

In addition, although the operation procedure by Embodiment 6 of this invention is as showing in FIG. 20, the case where user FB (delta) (for example, FIG. 7) is created in step S1, S2 is demonstrated.

FIG. 24 is an explanatory diagram showing a dialog creation operation of the user FB (δ) according to the sixth embodiment of the present invention, and FIG. 25 is an explanatory diagram showing a state when the user FB is used.

In FIG. 24, the drag and drop states of "Static Text" and "Edit Box" from the user-defined FB area 4 to the FBD program editing area 5, and the static text of the GUI parts are arranged so that character strings are assigned to parameter values (PARAMξ). ), The "Edit Box" of the GUI component is arranged, and the state of setting the association with the integer value of the constant FB is shown.

In Fig. 25, the user FB (δ) parameter in the FBD program editing area 5, in addition to the drag & drop state of the user FB (δ) from the user-defined FB area 4 to the FBD program editing area 5, On the setting dialog 11, the state which sets the parameter value PARAMξ of the internal processing of the user FB (delta) is shown.

In FIG. 20, as shown in FIG. 24, the dialog of the user FB (delta) is produced | generated and the parameter association is performed by step S7, S8. Then, by step S3-step S5, FIG. It will be in a state as shown in FIG.

In this case, the parameter acquiring means 309 acquires the parameter from the FB storing the parameter among the FBs used for the description of the internal processing of the user defined FB.

In other words, even when the function used in the internal processing of the user-defined FB and the parameter used in the internal processing of the function block are in the form of FIG. 42, the description is not performed using the technique shown in FIG. It is described that the value of the parameter is supplied to the constant FB as shown in Fig. 7 without using the input terminal of the user-defined FB.

As described above, according to the sixth embodiment of the present invention, since the parameter acquiring means 309 acquires the parameter from the FB storing the parameter among the FBs used for the description of the internal processing of the user-defined FB, the user The dialog for setting the constant value of the constant FB used in the internal processing of the positive FB can be provided, and has the same effect as described above.

Embodiment 7

Further, in the above-described Embodiments 5 and 6, by creating a dialog of the user-defined FB by the user, only the parameters that are desired to be variable when using the user-defined FB can be set from the dialog of the user-defined FB, and other parameters. When defining the user-defined FB's internal processing, the user sets the parameters in the parameter setting dialog box of the FB. When using the user-defined FB, the user-defined FB is set to a fixed value. The desired effect was achieved without damaging.

However, in the operation procedure (refer FIG. 20) by the said Embodiment 5, 6, the dialog of the user defined FB which implement | achieves the same function as the parameter setting dialog which the FB used by the technique of internal processing of a user defined FB has. A new job is generated to create a (step S7) and associate a parameter (step S8). Therefore, it is preferable to automatically generate the dialog of the user-defined FB so that the additional work (steps S7, S8) in FIG. 20 is unnecessary.

The following describes a seventh embodiment of the present invention in which a dialog of a user-defined FB is automatically generated and no new work (steps S7, S8) is necessary, with reference to FIGS. 26 to 32.

Fig. 26 is a block diagram showing the functional configuration of the seventh embodiment of the present invention, and the same reference numerals as those described above are omitted for clarity and the like. In this case, the user defined FB parameter setting means creating means 308 in the user defined FB creating means 303 replaces the parameter obtaining means 309 and the parameter association setting means 310 with the parameter information obtaining means 311. ). In the FB having parameters, detailed information about the parameters is stored.

Specifically, as shown in the explanatory drawing of FIG. 27, for example, for FB (φ) and constant FB, values of parameters such as data type, upper limit of value, lower limit of value, list of selectable values, and the like. The information on (phi), the name of the parameter, and GUI information for parameter setting such as attributes (type, size, color, etc.) of the GUI component when displayed on the dialog are stored. The above information structure is also the same in FIGS. 31, 34, and 38 described later.

In FIG. 27, the FB (phi) which has the parameter (phi) used in Embodiment 5 mentioned above, and the constant FB which has the integer value used in Embodiment 6 mentioned above are shown as a specific example.

Here, it is assumed that FB (information about the parameter φ of φ) includes data type = BOOL, parameter name = PARAMφ, and GUI component attribute = Edit Box. It is assumed that the information on the integer value includes data type = BYTE, parameter name = integer value, and GUI part attribute = Edit Box.

In addition, since the FB (φ) has a dialog for setting the parameter φ, when the information about the parameter φ is the same as the information used in the dialog, the information about the parameter φ is What is stored in the means for displaying the dialog may be used as it is or may be stored as another data table.

Fig. 28 is a block diagram showing Embodiment 7 of the present invention, schematically showing the main parts of a program creation device 1 for realizing a program creation support device and a program execution device. FIG. 29 is a flowchart showing the main part of the operation procedure according to the seventh embodiment of the present invention, and corresponds to the operation of step S4 described above (see FIG. 20). 30 is an explanatory diagram showing a state after the operation in FIG. 29.

31 is explanatory drawing which shows the other example of the detailed information about a parameter, and FIG. 32 is explanatory drawing which shows the dialog display state in the case of another information example.

Next, an operation procedure according to Embodiment 7 of the present invention will be described with reference to FIG. 20.

Here, the case where the user EB (epsilon) as shown in FIG. 28 is created in step S1, S2 is demonstrated. In addition, it is assumed that FB (φ) and constant FB shown in FIG. 27 and FB (ξ) described above (see FIG. 7) are used for the description of the internal processing of the user EB (ε).

In this case, steps S11 to S14 shown in FIG. 29 are executed in step S4 in FIG. 20.

Specifically, first, the following operation is performed in step S11 (parameter information acquisition means 311).

That is, as shown in Fig. 27, as information about the parameter φ of the FB (φ), data type = BOOL, the name of the parameter + PARAMφ, and the attribute of the GUI component = Edit Box are acquired, and the parameter is the parameter of the constant FB. As information about the integer value, data type = BYTE, parameter name = integer value, and GUI part attribute = Edit Box.

Subsequently, the following operation is performed in step S12 (user defined FB parameter setting means 301).

First, the display regarding the parameter (phi) acquired in step S11 is performed. At this time, since the name of the parameter is PARAMφ, the character string "PARAMφ" is displayed on the dialog. In addition, since the attribute of the GUI component of parameter (phi) is "Edit Box", "Edit Box" is displayed on a dialog.

In addition, "integer value" which is the next parameter is displayed below. Here, because the parameter name is an integer value, the string "Integer value" is displayed in the dialog box, and the "Edit Box" is displayed in the dialog box because the attribute of the GUI component of the integer value is "Edit Box". do.

Subsequently, the following operation is performed in step S13 (user defined FB parameter setting means 301).

First, a determination regarding the parameter? Is made. That is, it is determined whether the set parameter value is correct or not based on the information about the parameter value acquired in step S11 with respect to the value input by the user on the dialog displayed in step S12. At this time, since the data type of the parameter is BOOL, it is determined that it is correct when BOOL type data is input to [Edit Box].

In addition, an integer value which is another parameter is displayed. Here, since the data type of the parameter is BYTE, it is determined that it is correct when BYTE type data is input to the "Edit Box".

Finally, the following operation is performed in step S14 (user defined FB parameter setting means 301).

That is, the user-defined FB parameter setting value storage means 302 of the user FB (epsilon) saves the value judged to be correct in step S13. First, the value input to the "Edit Box" of the parameter (phi) is saved, and the value input to the "Edit Box" of the integer value which is another parameter is saved.

By executing the above steps S11 to S14, the FBD program editing area 5 is in a state as shown in FIG.

In FIG. 30, the drag & drop state of the user FB (ε) from the user-defined FB area 4 to the FBD program editing area 5, and the user FB (ε) parameter setting dialog (in the FBD program editing area 5) On 12), the state of setting the parameter value PARAMψ of the internal processing of the user FB (ε) is shown.

This makes it possible to automatically perform a process relating to a dialog for setting the parameters of the user EB (ε) without executing steps S7 and S8 in FIG.

That is, steps S11 and S12 in FIG. 29 execute a portion corresponding to step S7 described above, and steps S11 and S14 execute a portion corresponding to step S8 described above.

In addition, as detailed information regarding a parameter, it is not limited to the example of FIG. 27, As shown in FIG. 31, the information regarding parameters (tau, k) may be preserve | saved.

In this case, the PARAMτ in FIG. 31 is determined to be correct if the INT type data is input to the "Edit Box" in step S13, and the value is in the range of 0 to 999.

In addition, about PARAMκ in FIG. 31, a dialog as shown in FIG. 32 is displayed in step S12. That is, the "Combo Box" which selects and sets a desired value from a list of candidates sets the value of PARAMκ among "1, 2, 3, 4, 5" as a candidate for setting.

In FIG. 32, the state which sets the parameter value PARAMκ of the internal processing of the user FB on the user EB ((epsilon)) parameter setting dialog 12 is shown.

As described above, according to the seventh embodiment of the present invention, the parameter related to the processing contents of the user-defined FB has parameter value information about the value of the parameter and GUI information for setting the parameter. The FB creation means 303 further includes parameter information acquisition means 311.

The parameter information acquisition unit 311 acquires parameters related to the processing contents of the user-defined FB in the form of parameter value information and GUI information, and the user-defined FB parameter setting unit 301 is a parameter information acquisition unit. The setting dialog is displayed on the basis of the acquired GUI information (311) (step S12), and it is determined whether or not the set parameter value is correct based on the parameter value information acquired by the parameter information obtaining means (311) (step S13). ).

Among the FBs used for the description of the internal processing of the user-defined FB, the FB for storing the parameters has parameter value information about the parameter value and GUI information for setting the parameter.

The parameter value information has at least one of a data type of a parameter, an upper limit of a parameter, a lower limit of a parameter, and a list of selectable values among the parameters.

In addition, GUI information has the name of a parameter and the attribute of a GUI component at the time of displaying on the dialog of a user-defined FB.

This makes it possible to automatically provide a dialog for setting parameters used in the internal processing of the user-defined FB, and has the same effect as described above, while reducing the work of creating the dialog (steps S7 and S8). As a result, the creation time of the FBD program can be further shortened.

That is, in the sixth embodiment described above, only the material (existing) of the parameters used in the internal processing of the user-defined FB is automatically acquired, and the user-defined FB dialog must be manually created, and the GUI on the user-defined FB dialog is used. Although it was necessary to manually associate the parts with the parameters, in the seventh embodiment of the present invention, since the parameters used in the internal processing of the user-defined FB are acquired together with the detailed information, the dialog of the user-defined FB is automatically generated. It has the effect that it can be created and that there is no need to manually associate it.

Embodiment 8

In the seventh embodiment, a dialog for automatically setting parameters used in the internal processing of the user-defined FB is automatically provided to reduce the effort of creating the dialog of the user-defined FB. As described above, when using the user-defined FB, only the parameters to be changed are set from the dialog of the user-defined FB, and other parameters are set by the parameter setting dialog of the FB when describing the internal processing of the user-defined FB, and the user-defined FB. May always be a fixed value.

The following describes an eighth embodiment of the present invention in which the seventh embodiment is further developed with reference to FIGS. 33 to 37 together with FIG. 20.

33 to 37 correspond to the block diagram of FIG. 26 described above, the explanatory diagram of FIG. 27, the block diagram of FIG. 28, the flowchart of FIG. 29, and the explanatory diagram of FIG. 30, respectively.

In FIG. 33, the user defined FB parameter setting means creating means 308 also has parameter information use setting specifying means 312 associated with the parameter information obtaining means 311.

The parameter information use setting designation means 312 stores, for each parameter acquired by the parameter information acquisition means 311, a parameter stored by the FB used in the description of the internal processing of the user defined FB, by the user defined FB parameter setting means ( Or 301).

In Fig. 36, the difference from Fig. 29 is that step S11A (parameter information use setting setting means 312 has a setting flag for each parameter, and the setting flag between step S11 and step S12). Process of setting "0" or "1") is added.

In Embodiment 8 of the present invention, since all of the parameters of the FB used in the internal processing of the user defined FB can be set from the user defined FB, the user encapsulates a specific process in the form of a function block. Definition It is realized considering the nature of FB.

In Fig. 34, in addition to the specific example described above (see Fig. 27), whether or not the user-defined FB parameter setting means 301 sets the parameter stored by the FB used in the description of the internal processing of the user-defined FB = The parameter information usage setting designation means 312 has 1 for each parameter. As shown in Fig. 34, when the value of the setting flag is "1", it means that the parameter is set in the parameter setting dialog of the user-defined FB. On the other hand, when the value of the setting flag is "O", it means that the parameter is not set in the parameter setting dialog of the user-defined FB.

In addition, the operation procedure by Embodiment 8 of this invention is the same as that of Embodiment 7 (refer FIG. 20, FIG. 29).

In this case, as shown in FIG. 35 and FIG. 37, the case where the user EB (epsilon) (refer FIG. 28) as mentioned above in step S1, S2 is created is demonstrated.

Here, only the parameter PARAMφ of FB (φ) used for the description of the internal processing of the user FB (ε) is set in the user EB (ε) parameter setting dialog 12, and the parameter constant value of the constant FB is fixed. For the reason, as shown in FIG. 35, in the parameter setting dialog of FB (phi), it sets to blank without setting PARAMphi and sets constant value "123" in the parameter setting dialog of constant FB.

Thereby, the parameter information use setting designation means 312 leaves the information on the parameter φ blanked without setting the parameter, with the setting flag = 1, and the information on the integer value where the parameter setting is performed. Rewrite with setting flag = 0.

In Embodiment 8 of this invention, the following operation procedure (steps S11-S14) is performed specifically in step S4 (refer FIG. 20) like FIG.

First, the following operation is performed in step S11 (parameter information acquisition means 311).

As shown in Fig. 34, data type = BOOL, parameter name = PARAMφ, attribute of GUI component = Edit Box, and setting value = blank are obtained as information about the parameter? Of FB (?), And the constant FB has. As information on the integer value that is a parameter, data type = BYTE, parameter name = integer value, GUI part attribute = Edit Box, and set value = 123 are obtained.

Subsequently, the palladium make information use setting specifying means 312 having the setting flag has a setting flag for each parameter, and sets "0" or "1" to the setting flag (step S11A). ). Next, the display regarding the parameter φ with the setting flag = 1 is performed, and the determination regarding the parameter φ is performed without displaying the integer value with the setting flag = 0 (step S13). In step S13, since the data type of the parameter is BOOL, it is determined that it is correct when BOOL type data is input to the "Edit Box".

Finally, the value input to the "Edit Box" of the parameter (phi) is set to FB (phi) which is an acquisition source (step S14).

The above operation procedure (steps S11 to S14) results in a result as shown in FIG. 37, and it is possible to automatically perform a process relating to a dialog having only a parameter to be set as a parameter of the user EB (ε).

In FIG. 37, the drag & drop state of the user EB (ε) from the user defined FB area 4 to the FBD program editing area 5, and the user EB (ε) parameter setting dialog (in the FBD program editing area 5) On 12), a state of setting the parameter value PARAMφ of the internal processing of the user FB (ε) is shown.

As described above, according to the eighth embodiment of the present invention, the GUI information has at least a name of a parameter and an attribute of a GUI component when displaying on a dialog of a user-defined FB.

The user defined FB parameter setting means creating means further has parameter information use setting specifying means.

In addition, the parameter information use setting designation means 312 sets the user-defined FB parameter setting of the parameter which the FB used for the description of the internal processing of the user-defined FB with respect to each parameter acquired by the parameter information acquisition means 311. It has a setting flag of whether or not to set by the means 301.

This automatically provides a dialog for setting the parameters used in the internal processing of the user-defined FB, and achieves the same effect as described above. Only the parameters that are desired to be variable when the user-defined FB is used are the dialog of the user-defined FB. When other parameters are described in the internal processing of the user-defined FB, it is possible to realize the form using the value set in the parameter setting dialog of the FB with a little effort, and to execute a specific block as a function block. You can further reduce the time required to write FBD programs that take advantage of the user-defined FB's encapsulation.

Embodiment 9

In addition, in the eighth embodiment, the internally defined user defined FB is used in internal processing of the user defined FB to reduce the effort of creating the user defined FB dialog without impairing the property of the user defined FB that encapsulates a specific process in the form of a function block. Among the parameters to be set, only the parameters to be set are automatically provided in the dialog. However, in order to realize encapsulation, the internal processing of the user-defined FB can be described for the parameters of the user-defined FB that are not to be changed. It is necessary to set in the parameter setting dialog of the FB.

Parameters that are not made variable are always fixed when using the user defined FB, and are not displayed in the user defined FB dialog. That is, in order to confirm which parameter is set as variable when creating a user-defined FB and which parameter is fixed, it is necessary to individually display the dialog boxes of the FBs used in the internal processing of the user-defined FB. It takes effort.

So, in order to solve the said subject, in Embodiment 9 (refer FIG. 39, FIG. 40) of this invention, the dialog automatically generated like Embodiment 7, 8 was mentioned above Embodiment 5, 6 ( It is configured to be editable in the user-defined FB dialog editing area 7 (dialog editing means) in Figs. 19 and 24).

EMBODIMENT OF THE INVENTION Hereinafter, Embodiment 9 of this invention is described, referring FIG. 38 thru | or FIG. 40 along with FIG. 1, FIG. 20, FIG. 33, and FIG. 38-40 correspond to FIG. 34, FIG. 22, and FIG. 37 mentioned above, respectively.

In this case, the parameter information use setting designation means 312 (see FIG. 33) is an FB parameter setting means of the FB that is used for the description of the internal processing of the user-defined FB for each parameter acquired by the parameter information obtaining means 311. It also has a default value flag (see Fig. 38) of whether or not to use the value set in the above as the default value of the parameter set by the user-defined FB parameter setting means 301.

FIG. 38 is an explanatory diagram showing detailed information on parameters stored in Embodiment 9 of the present invention. In addition to the above-described information (see FIG. 34), FIG. 38 shows the FB used in the description of the internal processing of the user-defined FB. The default value flag of whether to use the value set by the FB parameter setting means 304 as a default value of the parameter set by the user-defined FB parameter setting means 301 is added.

Fig. 39 shows whether or not the value of the parameter PARAMφ (or PARAMψ) is set in the dialog of the user-defined FB in the user-defined FB dialog editing area 7, and is set in the dialog of the FB. The state which displayed the parameter attribute setting dialog 19 for setting whether to use one value as a default value is shown.

In addition, although the program creation apparatus 1 which implements Embodiment 9 of this invention is substantially the same as the structure shown in FIG. 19, the GUI component 8 for user defined FB dialog editing is unnecessary. In addition, although the procedure from the creation of the dialog which sets the parameter of the user defined FB to the setting of the parameter when the user defined FB is used in the program is almost the same as the procedure shown in Fig. 20 described above, step S8 is unnecessary. .

In the ninth embodiment of the present invention, first, in step S1 and S2 in FIG. 20, a user EB (ε) (see FIG. 28) is created similarly to the seventh embodiment.

However, only the parameter PARAMφ of FB (φ) used for the description of the internal processing of the user EB (ε) is set in the user EB (ε) parameter setting dialog 12, and the default value is set in the dialog of the user-defined FB. As shown in FIG. 39 (FIG. 40), the value "456" is set in PARAMφ on the user-defined FB dialog editing area 7 (EB (ε) parameter setting dialog 12). do. In addition, since the parameter constant value of the constant FB is fixed, the value "123" is set in the parameter setting dialog of the constant FB.

In addition, in the FB having parameters, the detailed information (see Fig. 27) regarding the parameters is stored similarly to the seventh embodiment described above.

Subsequently, in step S7 in FIG. 20, instead of creating a dialog, steps S11 and S12 in FIG. 29 are executed. Thus, the dialog of the user FB (ε) is automatically generated and displayed in the user defined FB dialog editing area 7.

That is, in Fig. 39, the value set in the dialog of the FB is displayed in "Edit Box". Here, a parameter attribute setting dialog 19 for setting whether or not to set the value of this parameter in the dialog of the user-defined FB is displayed by double-clicking a GUI component of one parameter or the like. When the value of the parameter is set in the dialog of the user-defined FB, the parameter attribute setting dialog 19 for setting whether or not to use the value set in the dialog of the EB as the default value is displayed.

Here, it is assumed that PARAMφ is not set in the dialog of the user-defined FB. In the parameter attribute setting dialog 19, as shown in the lower part in FIG. 39, the check box is excluded.

Further, the PARAM ψ is set in the dialog of the user-defined FB. In the parameter attribute setting dialog 19, as shown at the upper end in FIG. 39, a check box is placed. In this case, as shown at the top of Fig. 39, a check box for setting whether or not to use the value set in the FB dialog as a default value is displayed. Put it in.

Hereinafter, by performing steps S3 to S5 in FIG. 20, a state as shown in FIG. 40 is obtained.

As described above, according to the ninth embodiment of the present invention, the GUI information has at least the name of the parameter and the attribute of the GUI component when displaying on the dialog of the user-defined FB.

In addition, the parameter information use setting designation means 312 sets a value set by the FB parameter setting means of the FB, which is used in the description of the internal processing of the user-defined FB, for each parameter acquired by the parameter information acquisition means 311. It also has a default value flag of whether or not to use as a default value of a parameter set by the user-defined FB parameter setting means 301.

Thereby, as mentioned above, the dialog which sets the parameter used by the internal process of user defined FB can be provided automatically.

In addition, when using the user-defined FB, only the parameters to be changed can be set from the dialog of the user-defined FB, and the value set in the parameter setting dialog of the FB when the internal processing of the user-defined FB is described is defined. It is possible to display as a default value in the dialog box, and other parameters can be implemented with little effort in describing the internal processing of the user-defined FB using the value set in the parameter setting dialog box of the FB. . This makes it possible to further shorten the creation time of an FBD program that takes advantage of the user-defined FB's ability to encapsulate specific processing in the form of function blocks.

According to the present invention, parameters related to the processing contents of the user defined FB including the parameters of the FB used in the description of the internal processing of the user defined FB can be set from the user defined FB, so that the program creation time can be set. Can be shortened.
