Description

  The present invention relates to a program development support apparatus, a program development support method, a program development support program, and a recording medium on which a program development support program is recorded.

  In recent years, in the FA (Factory Automation) field, large-scale systems have been developed due to the spread of factory automation. For this reason, the sequence program is composed of a plurality of program components, and one sequence program written in one PLC (Programmable Logic Controller) is created by a plurality of creators. A program component is a component which comprises a sequence program. Generally, a sequence program is composed of a plurality of program components.

  In the development of a sequence program using an engineering tool, which is a computer that supports the creation of a sequence program, multiple creators share the creation of multiple program components, and finally the multiple program components are combined into a sequence. A technique in which a program is generated is common.

  In addition, since the sequence program goes through a debugging process and an on-site adjustment process before the sequence program operates in the factory, the program components are often changed from those originally created by the creator.

  Thus, in the development of a sequence program, since a plurality of program components are created by a plurality of creators, there is a problem that it takes time to identify the creators of the program components. It is important to specify the creator of the program component in order to shorten the sequence program design and maintenance work time.

  Patent Document 1 describes a sequence program editing method that allows a sequence program developer to display a program component having a right managed by the developer separately from other program components.

Japanese Patent Laid-Open No. 7-334213

  However, the conventional technique described in Patent Document 1 can display program components in different colors depending on whether or not there is a right to manage them, but allows the creator of the program components to be specified. It is not a thing.

  The present invention has been made in view of the above, and an object of the present invention is to provide a program development support apparatus that enables specification of a creator of a program component.

In order to solve the above-described problems and achieve the object, a program development support device according to the present invention includes first creation means for creating a component constituting an industrial device program created by a plurality of creators. A first table associating a step composed of one or more instructions among the constituent elements with a creator who creates the step, and a second table associating the constituent elements with a table name of the first table wherein the second generating means for generating association information, and storing means for storing the component and the correspondence information, based on the correspondence information after update of the association information, and the step step including Display means associated with the creator .

  According to the present invention, there is an effect that it becomes possible to specify a creator of a program component.

Note that the present invention is not limited to the embodiments.

Embodiment.
FIG. 1 is a block diagram showing an example of a hardware configuration of a program development support apparatus 1 according to the present embodiment. The program development support device 1 is a device that supports creation of a sequence program, and is a so-called engineering tool. The program development support device 1 is realized by a computer including a processor 1a, a memory 1b, an input device 1c, and a display device 1d. The processor 1a is generally a CPU (Central Processing Unit), and the memory 1b is generally a RAM (Random Access Memory) and a ROM (Read Only Memory). The input device 1c includes a keyboard and a pointing device. The display device 1d is a display.

  The program development support apparatus 1 generally includes an external storage device, an output device, and a communication device in addition to the processor 1a, the memory 1b, the input device 1c, and the display device 1d. Is omitted.

  The program development support apparatus 1 is realized by executing a program development support program on a computer. The program development support program is stored in the memory 1b, and the processor 1a reads the program development support program from the memory 1b and executes it.

  The sequence program is a program for operating the control system. The sequence program is composed of a plurality of program components. The program development support apparatus 1 enables creation, editing, and conversion of an execution code into a sequence program. The sequence program is described in a dedicated language such as a ladder language, ST (Structured Text) language, or SFC (Sequential Function Chart) language.

  FIG. 2 is a block diagram showing a functional configuration of the program development support apparatus 1 according to the present embodiment. The program development support apparatus 1 creates a program component creation unit 2 that creates each program component constituting the sequence program, and creates association information that associates the program component with the name of the creator of the program component. Program component based on the association information creation means 3, the association information storage means 4 that stores the association information created by the association information creation means 3, and the association information stored in the association information storage means 4 Is displayed in association with the creator of the program component.

  The program component creation means 2 accepts an input for creating a program component. The program component creation means 2 provides a navigation window and a program editor on the display screen of the display device 1d. In this embodiment, an example in which a navigation window of Outlook (registered trademark) of Microsoft (registered trademark) is used as a list display function for displaying data storage location and data in a computer will be described. The display function is not limited to the navigation window. The program editor is an editor used for creating and editing a program. The program component creation means 2 is a first creation means.

  Here, the program component is a component of the sequence program. A typical program component is a program component (POU: Program Organization Unit). POU is a functional unit of a program defined by IEC (International Electrotechnical Commission) 61131-3. Three types of programs, function blocks, or functions are defined in the POU. A circuit block or step in the POU is also a program component. The circuit block is composed of a plurality of circuits. A step consists of one or more instructions.

  The creator of the program component operates the input device 1c and can create the program component via the navigation window and the program editor using the ladder language, ST language, or SFC language.

  It should be noted that the creation of the program component includes editing such as correction. That is, the creator includes the editor.

  The program component creation means 2 is realized by the processor 1a, the memory 1b, the input device 1c, and the display device 1d shown in FIG.

  The association information creation means 3 creates association information that associates the information of the creator who created the program component with the program component created by the creator. At this time, the association information creating unit 3 adds the creation date and time information of the program component to the association information. The association information creating means 3 is realized by the processor 1a and the memory 1b shown in FIG. The association information creation unit 3 is a second creation unit.

  The association information storage unit 4 is a storage unit that stores association information. Further, the association information storage unit 4 stores program components. The association information storage unit 4 is realized by the memory 1b shown in FIG.

  The program component display unit 5 is a display unit that displays the program component together with information about the creator of the program component. When the association information is updated, the program component display means 5 displays the program component and the creator thereof based on the updated association information. The program component display means 5 is realized by the display device 1d shown in FIG.

  FIG. 3 is a diagram illustrating an example of a table including association information, and FIG. 4 is a diagram illustrating a table called from the table illustrated in FIG.

  In the table 10, for each POU name, a POU creator name or table name and a creation date and time are given. The creator name of “LD_Prog1” is “Taro Yamada”. The creator name is the name of the creator, and is not limited to the name of the true creator, but may be the name of a person estimated to be the creator. “LD_Prog1” represents the name of the POU. The creation date and time of “LD_Prog1” is “Y1.M1.D1.T1”. The creation date and time is a time stamp given by the date and time.

  The creator name of “LD_Prog2” is “Hanako Suzuki”. “LD_Prog2” represents the name of the POU. The creation date of “LD_Prog2” is “Y2.M2.D2.T2”.

  In contrast, “LD_Prog3” is associated with the table name “TBL1” instead of the creator name. The creation date of “LD_Prog3” is “Y3.M3.D3.T3”. “LD_Prog3” is created by a plurality of creators. In this way, POUs created by a plurality of creators are associated with table names indicating information of the plurality of creators instead of the creator names. In the table 11, information of a plurality of creators of “LD_Prog3” is managed for each step.

  That is, steps 0 to 3 of “LD_Prog3” are created by “Taro Yamada”, and the creation dates and times are all “Y3.M3.D3.T3”. Step 4 of “LD_Prog3” is created by “Hanako Suzuki”, and the creation date and time is “Y4.M4.D4.T4”. Here, the creation date “Y4.M4.D4.T4” is later than the creation date “Y3.M3.D3.T3”. As can be seen from the creation date and time of “LD_Prog3” being “Y3.M3.D3.T3” and the creation date and time of “LD_Prog3” from steps 0 to 3 being “Y3.M3.D3.T3”. In addition, “LD_Prog3” is initially created by “Taro Yamada”, and then step 4 is edited by “Hanako Suzuki”.

  Thus, in the tables 10 and 11, the creator name is managed for each POU name or each step of the POU.

  Note that a circuit block may be defined as a set of steps, and the creator name may be given to the circuit block number.

  FIG. 5 is a diagram showing another example of a table including association information, FIG. 6 is a diagram showing a table showing correspondence between creator IDs (IDentity) and creator names in the table shown in FIG. These are figures which show the table called from the table shown in FIG.

  In the table 12, the creator ID or the table ID and the creation date and time are given for each POU name.

  Specifically, “LD_Prog1” is created by the creator with the creator ID “0001”. “LD_Prog2” is created by the creator of the creator ID “0002”. The creation date and time is the same as in FIG.

  On the other hand, “LD_Prog3” is associated with the table ID “t0001” instead of the creator ID.

  The table 13 gives a creator name for each creator ID. It can be seen from the table 13 that the creator ID “0001” corresponds to the creator name “Taro Yamada” and the creator ID “0002” corresponds to the creator name “Hanako Suzuki”.

  In the table 14, information on the creator of “LD_Prog3” is managed for each step. The table 14 is substantially the same as the table 11 except that the creator ID is given for each step.

  FIG. 8 is a diagram illustrating another example of a table for managing creators for each POU step. The table 15 replaces the table 14 shown in FIG. 7, and is used in combination with the table 12 shown in FIG. 5 and the table 13 shown in FIG.

  In the table 15, both the creator ID “0002” and the creator ID “0001” are associated with Step 4. Step 4 is created on the creation date “Y3.M3.D3.T3” by “Taro Yamada” who is the creator of the creator ID “0001”. Step 4 is created on the creation date “Y4.M4.D4.T4” by “Hanako Suzuki” who is the creator of the creator ID “0002”. As described above, the creation date “Y4.M4.D4.T4” is later than the creation date “Y3.M3.D3.T3”. That is, step 4 is created by the creator ID “0001” with the creator ID “0002” after being created on the creation date “Y3.M3.D3.T3” by “Taro Yamada” who is the creator of the creator ID “0001”. Edited by “Hanako Suzuki” on the creation date “Y4.M4.D4.T4”.

  Thus, FIG. 8 shows a management example in the case where Step 4 is created by “Taro Yamada” and then edited by “Hanako Suzuki”. A similar management method can be applied to a case where editing is performed after the POU is created. For example, in the table 12 shown in FIG. 5, “LD_Prog2” is created by the creator of the creator ID “0002” in “Y2.M2.D2.T2”. Furthermore, in the table 12 shown in FIG. 5, “LD_Prog2” is the creator of the creator ID “0003” at “Y4.M4.D4.T4”, which is later than “Y2.M2.D2.T2”. Has been created by. This indicates that “LD_Prog2” created by the creator with the creator ID “0002” has been edited to “Y4.M4.D4.T4” by the creator with the creator ID “0003”. Yes. As described above, referring to the table 12 shown in FIG. 5, after the creator with the creator ID “0002” is created in “Y2.M2.D2.T2”, it is edited by the creator with the creator ID “0003”. You can see that

  The association information storage unit 4 can store a plurality of elements having different creation dates and times for the program components having the same name. That is, the association information storage unit 4 can store a plurality of program components before and after editing with different creation dates and times. Even in this case, the program component display means 5 refers to the association information when displaying the program component in association with the creator of the program component, and displays the program component of the latest creation date and time as the program. Display in association with the creator of the component. Thereby, the program component display means 5 can display the program component of the latest creation date and time.

  FIG. 9 is a diagram illustrating still another example of the association information. That is, the table 16 gives the creator name and creation date and time for each program file name constituting the sequence program. The creator name can be replaced with the creator ID.

  Next, the operation of the program development support apparatus 1, that is, the program development support method according to the present embodiment will be described. FIG. 10 is a flowchart showing the program development support method according to the present embodiment.

  First, in S <b> 1, the program development support device 1 acquires user information and holds the user information as creator information. Specifically, the user of the program development support apparatus 1 registers user information when the program development support apparatus 1 is activated. At this time, the program development support device 1 displays a user authentication dialog on the display screen of the display device 1d, and accepts an input of a user name by the input device 1c. The user authentication dialog is a screen that is displayed to accept input of information necessary for authentication such as a user name. In other words, the input device 1c is an input unit that receives input of information on a person who creates all or part of the program. Here, the user name includes a name, an arbitrary account name, an arbitrary ID, or a personal number. The ID includes an in-house management ID or a system account name. The system account name is an account name for logging in to a computer having a function as the program development support apparatus 1. As the user authentication dialog, an authentication dialog for logging in to the computer when the computer having the function as the program development support apparatus 1 is started can be used. In this case, the program development support apparatus 1 acquires a user name by acquiring a login ID from an OS (Operating System) in a computer having a function as the program development support apparatus 1. Alternatively, the user authentication dialog may be displayed when a program for realizing the program development support apparatus 1 is started in a computer having a function as the program development support apparatus 1. .

  The program development support apparatus 1 is linked with an internal management system such as a directory service such as Microsoft's Active Directory (Active Directory (registered trademark)), and from the internal management system when the program development support apparatus 1 is started. User information can also be acquired. Thus, the user can save the trouble of registering the user information when the program development support apparatus 1 is activated. In addition, user information is centrally managed. The directory service is a service that collects, records, and searches information such as resources on a computer network and their locations, attributes, and settings. The user name may be input from the user to the program development support apparatus 1 when editing the sequence program.

  Next, in S2, the program development support apparatus 1 creates a program component. Specifically, the program component creation means 2 creates a program component.

  The user creates a program component by, for example, the following operation. That is, the user selects a POU in the navigation window to display a shortcut menu, selects a program editor from the shortcut menu, and edits a circuit block or step in the POU using the program editor. Here, editing is creation, deletion, or modification. The shortcut menu is a menu displayed by right-clicking the mouse in Windows (registered trademark), and an application to be activated is included in this menu. Therefore, if a program editor is selected as an application, the selected program editor is activated, and the selected POU can be edited.

  Next, in S3, the program development support apparatus 1 determines whether or not there is an association request. That is, the association information creation unit 3 determines whether or not there is an association request from the program component creation unit 2. Here, the association request is an association information creation request for associating a program component with the creator of the program component. The association request may be executed each time a program component is created, or may be sequentially executed during editing by the program editor even during creation of the program component, or the execution code of the sequence program It may be implemented collectively at the time of conversion to, or may be implemented collectively at the end of creation or editing of the program component.

  If there is no association request as a result of the determination in S3, the association information creation means 3 continues to create the program component in S2, and proceeds to S4 if there is an association request.

  In S4, the program development support apparatus 1 creates association information that associates the program component created by the program component creation means 2 with the creator information of the program component. Specifically, the association information creation unit 3 creates association information. Here, the creator information is user information. The association information creation unit 3 stores the association information in the association information storage unit 4.

  As described with reference to FIGS. 3 to 9, the association information includes information for associating the POU name with the creator for each POU name, information for associating the step number with the creator for each step number, and circuit Information for associating a circuit block number with a creator for each block number or information for associating a program file name with a creator for each program file name is exemplified.

  Next, in S5, the program development support apparatus 1 updates the display screen of the program components. Here, the program component display screen is a display screen displayed by the program component display means 5. The program component display unit 5 updates the display screen based on the association information stored in the association information storage unit 4.

  Next, in S6, the program development support apparatus 1 determines whether or not to finish the creation of the program component, and if the creation is continued, returns to the process of S2, and if the creation is finished, The process is terminated.

  Here, the details of the process of S5 will be described. The program component display means 5 displays the created program component on the display screen for each program component creator. Further, the program component display means 5 updates the display screen at the timing when the association information is updated.

  FIG. 11 is a diagram showing an example of the contents displayed by the program component display means 5. The display 20 is a ladder format display by a program editor. The display 20 displays the POU for each step. As shown in the display 20, the program component display means 5 inserts a note indicating the creator information before the step of switching the creator and displays the creator information. That is, when the creator of a program component differs between adjacent steps, a note indicating the creator's information is inserted between adjacent steps. The creator information in this case is information on the creator of the program component of the subsequent step having a larger step number. A note is a statement that describes the name of the creator and the scope of the steps created by the creator.

  Specifically, since the creator “Taro Yamada” has created steps 0 to 10 of the POU, note 21 is inserted before step 0, and the creator name “Taro Yamada” is entered in note 21. “Step: 0-10” which is the creation range is described. Also, since the creator “Hanako Suzuki” has created steps 11 to 38 of the POU, a note 22 is inserted before step 11, and the note 22 has the creator name “Hanako Suzuki” and the creation range. A certain “step: 11-38” is described. Furthermore, since the creator “Jiro Sato” created Steps 39 to 46 of the POU, a note 23 is inserted before Step 39, and in the note 23 the creator name “Jiro Sato” and the creation range A certain “step: 39-46” is described.

  FIG. 12 is a diagram showing another example of the contents displayed by the program component display means 5. The display 25 is a ladder format display by the program editor. The display 25 displays the POU for each step. In the display 25, steps are displayed using the color individually assigned for each creator as the background color. That is, a plurality of different colors are assigned to a plurality of creators in advance, and the step is displayed with the background color changed for each creator.

  Specifically, the creation range 26 of the creator “Taro Yamada” is displayed in orange. The creation range 27 of the creator “Hanako Suzuki” is displayed in yellow. However, in FIG. 12, the creation ranges 26 and 27 are surrounded by a broken line, and the creation range 27 is surrounded by a one-dot chain line, instead of being actually colored. Further, the assignment of these colors is an example, and the present invention is not limited to these.

  FIG. 13 is a diagram showing still another example of the contents displayed by the program component display means 5. A display 30 is a display of a navigation window. In the display 30, the POU is displayed using the color individually assigned for each creator as the background color. That is, a plurality of different colors are assigned to a plurality of creators in advance, and the POU is displayed with the background color changed for each creator.

  Specifically, the creation range 31 representing “MAIN / LD_Prog1” that is a POU created by the author “Taro Yamada” is displayed with an orange background color. The creation range 32 representing “MAIN1 / LD_Prog2” that is a POU created by the creator “Hanako Suzuki” is displayed with a yellow background color. A creation range 33 representing “MAIN2 / ST_Prog” that is a POU created by the creator “Jiro Sato” is displayed with a green background color. However, in FIG. 13, the creation ranges 31 to 33 are surrounded by a dotted line, the creation range 32 is surrounded by a one-dot chain line, and the creation range 33 is surrounded by a broken line, instead of being actually colored. Yes. Further, the assignment of these colors is an example, and the present invention is not limited to these.

  FIG. 14 is a diagram showing still another example of the contents displayed by the program component display means 5. The display 35 is a ladder format display by the program editor. The display 35 displays the POU for each step. In the display 35, when the cursor of the pointing device is on the program component, a tool tip 36 in which information of the creator of the program component is described is displayed. When the user moves the cursor to the object, the tooltip is displayed in an area near the object or an area including the object, and the tooltip describes information about the object. The

  FIG. 14 shows an example in which the creator moves the pointing device cursor on the program component to display the tooltip 36 on the program editor, but the same applies to the navigation window as shown in FIG. Can be displayed.

  FIG. 15 is a diagram showing still another example of the contents displayed by the program component display means 5. The displays 40a and 40b are ladder format displays by a program editor. The displays 40a and 40b display the POU for each step. The displays 40a and 40b display the creation range 41 in a blinking manner by switching to each other. That is, the program component display means 5 blinks and displays the program component creation range 41 created by the designated creator. As described above, the program component display means 5 is a display means for displaying the whole or a part of the program together with information of the creator.

  Here, the creator can be specified by providing a search function to the program development support apparatus 1 and inputting the creator information into the program development support apparatus 1.

  FIG. 16 is a block diagram illustrating an example of a functional configuration of a program development support apparatus according to a modification of the present embodiment. A program development support device 1e shown in FIG. 16 includes a program component search means 6 in addition to the configuration of the program development support device 1 shown in FIG.

  The program component search means 6 receives the creator information as input and searches for the program component created by the creator based on the association information. The creator's information is input from the display screen of the display device 1d by the user via the input device 1c. The creator information is, for example, the creator name.

  The program component display means 5 can display the search result. As shown in FIG. 15, the program component display means 5 can blink and display a program component creation range 41 created by the creator as a search result.

  The search result display method is not limited to the display example of FIG. The program component display means 5 can also display a list of program components and creation dates created by the creator as search results. That is, the search results are displayed according to the contents described in the tables shown in FIGS.

  Further, FIG. 15 shows an example of blinking display on the program editor, but similar blinking display can be performed on the navigation window as shown in FIG.

  Further, the program component display means 5 can switch between the display as shown in FIGS. 11 to 15 and the normal display that does not display the creator information on the sequence program. In the example described above, the program that is the target for displaying the creator's information is described as a sequence program composed of a plurality of program components. However, there are a plurality of programs that are intended for displaying the creator's information. The program is not limited to the sequence program as long as it is a program that may be created by the creator. In other words, the program that is the target for displaying the creator information may be a program that is composed of a plurality of components and may be created by different creators in units of components. For example, a program in an industrial apparatus such as a servo controller, a motion controller, a robot control, and a numerically controlled machine tool can be a program that is a target for displaying creator information.

  As described above, according to the present embodiment, the creator of the program component can be specified. As a result, the creator of the program component can be distinguished, so that the creator can be easily identified, and the man-hours for design and maintenance can be reduced. Specifically, the following effects can be obtained.

  Since the creator of the program component can be specified, troubleshooting when a problem occurs can be facilitated, and the number of defect correction man-hours can be reduced.

  Since the creator of the program component can be specified, the intention of the creator can be confirmed when the program component is diverted, and the design man-hour can be reduced.

  Since the creator of the program component can be specified, when a plurality of program components are combined to generate one sequence program, it is easy to specify a portion to be combined, and man-hours can be reduced.

  Further, in the present embodiment, information on the creation date and time of the program component is added to the association information. This makes it possible to determine when the creator has created the program component. In FIG. 11 to FIG. 15, information on the creation date / time of the program component is not displayed, but information on the creation date / time may be displayed together with information on the creator of the program component.

  In the present embodiment, the association information creating unit 3 creates association information in response to the association request. As a result, the timing of creating the association information can be controlled. The association request may be executed each time a program component is created, or may be sequentially executed during editing by the program editor even during creation of the program component, or the execution code of the sequence program It may be implemented collectively at the time of conversion to, or may be implemented collectively at the end of creation or editing of the program component.

  In the present embodiment, the program component display means 5 inserts a note indicating the creator's information before the step of switching the creator when the program component is displayed for each step. Information can be displayed. As a result, the creator's marking becomes possible, so that it is possible to easily distinguish the responsible portion of each creator.

  In the present embodiment, the program component display means 5 is created by the creator using the color individually assigned for each creator as the background color when the program component is displayed for each step. Step can be displayed. Thereby, it becomes easy to distinguish the creator.

  Further, in the present embodiment, the program component display means 5 is created by the creator using the color individually assigned for each creator as the background color when the program component is displayed in the navigation window. Program components can be displayed. Thereby, it becomes easy to distinguish the creator.

  Further, in the present embodiment, the program component display means 5 can display a tool tip in which information of the creator of the program component is described when the pointing device cursor is on the program component. . This is convenient because the creator information can be obtained by individually specifying the program components.

  Further, in the present embodiment, the program component display means 5 can blink the program component created by the creator. This makes it possible to easily check the creation range of the designated creator.

  In the present embodiment, the association information storage unit 4 stores association information. The association information is exemplified in the tables shown in FIGS. If such association information is used, it is also possible to search for program components created by the creator from the creator's information.

  Other effects of the present embodiment are as already described with the description of the configuration and operation.

  The program development support program can be recorded on a recording medium so as to be readable by a computer. The recording medium is an optical, magnetic or electrical recording medium. The recording medium is, for example, a CD-ROM, a DVD disk, a hard disk, a magneto-optical disk, a flexible disk, or an IC card.
