Description
Technical Field
The present invention relates to a program creation support device, a program creation support method, and a program creation support program that support creation of a sequence program.
Background
A Programmable Logic Controller (PLC) is a control device that operates according to a sequence program and controls a controlled device installed in a factory or the like.
As a main description language of the sequence program, there is a ladder diagram language. The ladder diagram language is a programming language realized by simulating a graphic representation of a relay circuit, and can create a program by configuring circuit components such as contacts and coils that transmit control signals, specifying their connection relationship. Further, the control signal is distributed to an internal memory of the PLC, but the internal memory is referred to as a "device". In addition, a sequence program described in a ladder language is called a ladder program. In the ladder program, symbols such as X and Y are combined with numerical values to represent devices, and the devices are assigned to contacts and coils, respectively, to thereby represent signal transmission.
Here, in recent years, the scale of production equipment has been increasing, and along with this, the number of controlled instruments controlled by the PLC has increased, and the sequencing program has also been increasing in scale. Accordingly, techniques for enabling efficient creation of sequencing programs have been proposed.
For example, in the invention described in patent document 1, focusing on the fact that the same circuit pattern is used a plurality of times in 1 sequence program, it is possible to efficiently create the sequence program. Specifically, in the invention described in patent document 1, a common circuit pattern is extracted from an already created sequence program and is formed into a component, and a program component, which is a circuit pattern formed into a component, can be reused for creating a subsequent sequence program and the like.
Patent document 1: japanese patent No. 5769900
Disclosure of Invention
In the invention described in patent document 1, the definition of program components, i.e., the definition of input/output parameters, is automatically determined. Specifically, the input/output parameters of the program components are defined as those for transmitting the input/output parameters to all the device assignments made to the circuit components (contacts, coils, etc.) in the common circuit pattern. Therefore, for example, when there are 5 contacts and 3 coils in the common circuit pattern, the program components generated from the common circuit pattern have 5 input parameters (the number of contacts) and 3 output parameters (the number of coils).
In addition, in a plurality of circuits which are extraction sources of a common circuit pattern, the same circuit components are allocated to the devices, and the device allocation is not required to be transmitted from the outside as parameters, so that the parameters of the program components can be omitted. In the sequence program, the smaller the number of input/output parameters of the program components used, the higher the readability and maintainability, and the smaller the program capacity. However, the invention described in patent document 1 has a problem that it is not considered to reduce the number of input/output parameters of the program components, that is, to improve readability and maintainability of the sequence program.
The present invention has been made in view of the above circumstances, and an object thereof is to obtain a program creation support device capable of improving readability and maintainability of a sequence program.
In order to solve the above problems, a program creation support device according to the present invention includes a common determination unit that extracts a common logic portion from the entire circuit within a sequence program and generates, for circuit components included in the extracted common logic portion, auxiliary information indicating whether or not device assignments made for circuit components at the same position are identical in all the common logic portions. Further, the program creation support device includes: a program component generation unit that generates a program component based on the common logical part and the attached information extracted by the common determination unit; and a replacing unit that replaces the common logic portions in the sequence program with the program modules and the circuit components connected to the input/output parameters of the program modules. The program module generating unit is configured to assign circuit components that are identical in all common logic portions to devices made for circuit components at the same position in the accessory information, and to enable a user to select whether or not to generate the input/output parameters.

Detailed Description
Hereinafter, a program creation support device, a program creation support method, and a program creation support program according to embodiments of the present invention will be described in detail with reference to the drawings. The present invention is not limited to the present embodiment.
In the following embodiments, the "common circuit pattern G" and the "common logic portion H" are described as follows.
Common circuit pattern G: a pattern of logic that appears in common in a sequencing program.
Common logic portion H: the portion (region) where the common circuit pattern G sequencing program appears.
In the following description, the sequence program to be processed by the program creation assistance apparatus is made a ladder program.
Provided is an implementation mode.
First, an outline of the operation of the program creation support device according to the present embodiment will be described. The program creation support device according to the present embodiment has at least 2 functions shown below, and supports creation of a sequence program by a user using these functions.
The 1 st function is a function of searching and displaying a common logic portion H that can be formed into parts from the entire circuit of the sequence program. A ladder program, which is a sequence program, is composed of commands corresponding to contacts or coils and application commands corresponding to numerical calculations and the like. Therefore, the program creation support device searches for and displays a program portion (common logic portion H) and a common circuit pattern G that are logically common only to a contact-equivalent command that is a command equivalent to a contact, a coil-equivalent command that is a command equivalent to a coil, and an application command equivalent to numerical calculation or the like. The retrieved common circuit pattern G is a candidate for a program component, i.e., a program part (macro, subroutine, etc.).
The 2 nd function is a function of converting the selected common circuit pattern G into a program component (execution component) and registering it if the user selects any one of the common circuit patterns G retrieved by the 1 st function. In addition, the 2 nd function automatically composes the sequence program by replacing the common logical part H retrieved by the 1 st function with the registered instance of the program component.
Here, in the above-described function 1, when searching for the common logic portion H, the program creation assistance means holds information as to whether or not the device assignment made for each circuit component in the circuit, such as the contact and the coil, is consistent. That is, the extracted common circuit pattern G is stored as attached information as to whether or not the device assignments made to the circuit components arranged at the same coordinates are matched in the common logic portion H from which all the common circuit patterns G originate. The coordinates here show the position within the circuit pattern of the circuit component. Therefore, the circuit components arranged at the same coordinates refer to circuit components arranged at the same position within the common circuit pattern G.
When the program component is generated in the 2 nd function, the program creation support device determines the parameter of the program component based on the accessory information stored when the common logical section H is searched by the 1 st function. Specifically, when there are circuit components having inconsistent device assignments despite being arranged at the same coordinates between the common logic portions H, the program creation assistance means generates a program component having parameters for assigning devices to the circuit components.
This prevents the input/output parameters of the program components generated by the program creation support device from exceeding a required amount, and improves the readability and maintainability of the sequence program. In addition, the capacity of the sequence program can be reduced.
Fig. 1 is a diagram showing an outline of a program component generating operation of a program creation support device according to an embodiment.
As shown in stage (a) of fig. 1, the program creation assisting means extracts a common logical part H from within the sequencer program. Here, the program creation assistance apparatus extracts the modules configured with the circuit modules 2a to 4a as a common logic portion H.
Then, as shown in stage (B) of fig. 1, the program creation assistance device sets the common circuit pattern G that can be formed into parts based on the logic of the circuit modules 2a to 4 a. In other words, the program creation assistance device sets the logic common to the circuit modules 2a to 4a to the common circuit pattern G. Thus, the program creation assistance device treats the circuit modules 2a to 4a as the common circuit pattern G.
At this time, the program creation support device checks whether or not the device assignments made to the circuit components of the same coordinates in the extracted circuit modules 2a to 4a match, and stores information indicating the result of the check (information indicating whether or not the device assignments match). In the example shown in fig. 1, the coordinates of the circuit component located at the upper left of the circuit modules 2a to 4a are (0, 0), the coordinates of the circuit component located at the right adjacent to the component are (1, 0), and the coordinates of the circuit component located next to the right adjacent to the component are (2, 0). In addition, the coordinates of the circuit component next to the circuit component located on the upper left are (0, 1), the coordinates of the circuit component located adjacent to the right of the component are (1, 1), and the coordinates of the circuit component located adjacent to the next right of the component are (2, 1). The method of determining the coordinates indicating the positions of the circuit components is not limited to this. In addition, the arrangement of the circuit components is not necessarily expressed by coordinates. As long as the arrangement of each circuit component in the circuit module can be known, the arrangement of each circuit component may be represented by information other than coordinates.
In the example shown in fig. 1, the device assignments made for the circuit components of coordinates (0, 0) and (1, 1) are not consistent among the circuit modules 2a to 4a, and the device assignments made for the circuit components of the other coordinates are consistent among the circuit modules 2a to 4 a. Therefore, the program creation assistance device generates and stores information indicating that the device assignments made for the circuit components having the coordinates (0, 0) and (1, 1) do not coincide among the circuit modules 2a to 4a, and the device assignments made for the circuit components having the coordinates (1, 0), (2, 0), (0, 1) and (2, 1) coincide among the circuit modules 2a to 4a in the stage (B). In the following description, circuit components whose devices are assigned to be identical among all the common logic portions H (circuit blocks 2a to 4a in fig. 1) are referred to as 1 st circuit components, and circuit components which do not belong to the 1 st circuit components are referred to as 2 nd circuit components, as necessary.
Next, as shown in stage (C) of fig. 1, the program creation support device causes the display device to display a screen 101, which is a screen for specifying the generation of the input/output parameters of the program component, based on the information generated and stored in stage (B). Also, the program creation assistance apparatus receives, from the user, a selection of a circuit component that generates the input-output parameter. Here, it is necessary to generate input/output parameters for the 2 nd circuit component whose device assignment does not match each other, that is, whose device assignment does not match each other completely between the circuit modules 2a to 4 a. Therefore, the screen 101 shown in fig. 1 is configured to display the circuit component having the coordinates (0, 0) and the circuit component having the coordinates (1, 1) so that the user knows that the input/output parameter needs to be generated, and not to receive a selection operation by the user.
If the selection of the 1 st circuit component by the user to generate input-output parameters is finished, the program creation assistance device transitions to stage (D). That is, if the program creation support device receives an operation from the user to end the selection of the 1 st circuit component for generating the input/output parameter, the screen 102, which is the profile image confirmation screen after the replacement to the program component, is displayed on the display device. In the screen 102 illustrated in fig. 1, the sequence program before replacement with the program component is displayed on the left side, and the sequence program after replacement with the program component is displayed on the right side. In addition, on the screen 102, the display contents in which the program component and the circuit module are associated with each other are displayed so that which circuit module is replaced with the program component can be known. The display content on the right side of the screen 102 follows the operation content received from the user in stage (C). On the screen 102 illustrated in fig. 1, a program component in the case where the user selects generation of a parameter corresponding to a coil as a circuit component having coordinates (2, 0) is displayed.
After confirming the screen 102, the user presses an "OK (execute)" button on the lower right of the screen 102 when generating a program component and replacing a circuit module with the program component. After confirming the screen 102, the user presses a "cancel" button on the lower right of the screen 102 when selecting a circuit component for generating input/output parameters again. If the cancel button is pressed, the program creation assistance apparatus returns to stage (C).
When the "OK" button on the screen 102 is pressed, the program creation support apparatus shifts to a stage (E) of fig. 1 to generate a program component fb (function block). At this time, the program creation assistance apparatus generates a program component of the structure shown on the right side of the screen 102 displayed by the display apparatus in stage (D).
Then, if the generation of the program components is completed, the program creation support device shifts to a stage (F) of fig. 1, and replaces the circuit modules 2a to 4a extracted in the stage (a) with the program components generated in the stage (E) to create the circuit modules 2b to 4 b.
With such a flow, the program creation support device generates a program component from the sequence program, and replaces, as the program component, a circuit module that can be replaced with the generated program component among circuit modules of the sequence program. The program creation support device saves the generated program components so as to be usable for editing another sequence program, developing another sequence program, and the like.
Fig. 2 is a diagram showing a configuration of a program creation system including the program creation support device according to the embodiment. The program creation system 100 includes a program creation support device 1, a sequence program creation device 2, a sequence program editing device 3, and a display device 5. In the present embodiment, the program creation support device 1, the sequence program creation device 2, the sequence program editing device 3, and the display device 5 are described as separate devices, but the functions of the devices may be implemented in a computer system such as a personal computer or the like, for example, in 1 device.
As described above, the program creation support device 1 extracts the common logical part H from the sequence program and generates a program component in accordance with an instruction from the user.
The sequencer program creating apparatus 2 is an apparatus that creates a sequencer program that runs in a plc (programmable Logic controller) system also called a sequencer. The sequencer program creating device 2 inputs the created sequencer program to the program creation support device 1.
The sequence program editing apparatus 3 is an apparatus for editing a sequence program using a sequence program replaced with program components in the program creation supporting apparatus 1. The display device 5 is a liquid crystal monitor or the like, and displays a sequence program, a common circuit pattern G, program components, and the like in accordance with an instruction from the program creation support device 1.
The program creation support device 1 includes a program input unit 11, a program storage unit 12, a common determination unit 13, a search result storage unit 14, a search result display processing unit 15, an instruction input unit 16, a program component registration unit 17, a program component storage unit 18, a component processing unit 19, an output unit 20, a component definition display processing unit 21, and a component general image display processing unit 22.
The program input unit 11 receives the sequence program input from the sequence program creation device 2, and sends the received sequence program to the program storage unit 12.
The program storage unit 12 is a memory or the like in which a sequence program (program to be a component) for searching the common logical part H is stored. The program storage unit 12, upon receiving the sequence program from the program input unit 11, stores the received sequence program. When a request or the like is received from the sequencer program editing apparatus 3, the program storage unit 12 outputs the requested sequencer program to the output unit 20. The sequence program output to the output unit 20 is transferred from the output unit 20 to the sequence program editing apparatus 3. When the replacement processing is performed in which the circuit modules used for generating the program components among the circuit modules constituting the stored sequence programs are replaced with the program components by the component processing unit 19, which will be described later, the program storage unit 12 stores the sequence programs after the replacement processing.
The common determination unit 13 reads the sequence program stored in the program storage unit 12, and determines whether or not there is a common logical part H. When the common determination unit 13 has the common logic portion H, the common logic in the common logic portion H is extracted as the common circuit pattern G. In other words, the common determination unit 13 extracts a logic pattern that is commonly expressed by circuit patterns disposed in the common logic portion H as the common circuit pattern G. When determining whether or not the common logical section H exists in the sequence program, the program creation support device 1 uses a known code clone detection method or the like. The code clone detection method refers to a method of finding a similar code block from among source codes representing a program. Similar code blocks that make up the source code are referred to as code clones.
The common determination unit 13 also confirms whether or not the device assignments made to the circuit components arranged at the same coordinates in all the common logic sections H match, and generates the accessory information of the common circuit pattern G as information indicating the confirmation result. The common determination unit 13 confirms whether or not the device assignments match in all the common logic sections H for each of the plurality of circuit components included in the plurality of common logic sections H, and generates accessory information indicating the confirmation result. The attached information shows the confirmation results for each of the plurality of circuit components included in the common logic section H. For example, when the common logic portion H includes 4 circuit components #1 to #4, the auxiliary information includes information on whether or not the device assignment made to the circuit component #1 matches all of the common logic portions H, information on whether or not the device assignment made to the circuit component #2 matches all of the common logic portions H, information on whether or not the device assignment made to the circuit component #3 matches all of the common logic portions H, and information on whether or not the device assignment made to the circuit component #4 matches all of the common logic portions H.
The search result storage unit 14 is a memory or the like that stores the information of the common circuit pattern G and the accompanying information extracted by the common determination unit 13 as a search result. That is, if the common determination unit 13 extracts the common circuit pattern G, the search result storage unit 14 receives the information indicating the structure of the extracted common circuit pattern G and the accompanying information, and stores the received pieces of information as search results. Hereinafter, the information indicating the structure of the common circuit pattern G is referred to as structure information.
The search result display processing unit 15 displays the search results stored in the search result storage unit 14 on the display device 5 in a list format. If the user selects the common circuit pattern G to be formed into a component from the search results being displayed, the search result display processing unit 15 transmits the configuration information and the accessory information of the selected common circuit pattern G to the component definition display processing unit 21 as information related to the common circuit pattern G.
The instruction input unit 16 receives an instruction input by the user, and outputs information indicating the content of the instruction to a part or all of the search result display processing unit 15, the component definition display processing unit 21, and the component-created general-image display processing unit 22. The instruction of the user is a search instruction which is an instruction relating to search, a component specification instruction which is an instruction relating to componentization, an instruction indicating whether or not to generate a parameter and to determine componentization, an output instruction which is an instruction relating to output, or the like.
The search instruction is an instruction to search for the common circuit pattern G from within the sequence program, and is sent from the instruction input unit 16 to the common determination unit 13. The component specification instruction is an instruction to specify the common circuit pattern G to be formed into components from among the search results, and is transmitted from the instruction input unit 16 to the search result display processing unit 15. The parameter generation/non-generation instruction is an instruction for specifying whether or not to generate the input/output parameter of the program component corresponding to the common circuit pattern G, and is transmitted from the instruction input unit 16 to the component definition display processing unit 21. The component creation determination instruction is an instruction for specifying whether to create a component or cancel the component based on a result of confirmation of replacing a circuit module that is a part of the sequence program with a program component. The component determination instruction is sent from the instruction input unit 16 to the component-created-profile-image display processing unit 22. The output instruction is an instruction to output the sequence program to the sequence program editing apparatus 3 or the like which is an external apparatus, and is transmitted from the instruction input unit 16 to the output unit 20.
When definition information of a program component is transmitted from a component-forming-profile-image display processing unit 22 described later, the program component registration unit 17 converts the common circuit pattern G into a program component based on the transmitted definition information, and forms the program component into a component. That is, the program component registration unit 17 is a program component generation unit that generates a program component as a program component based on the common circuit pattern G and the definition information. The program component registration unit 17 registers the generated program components in the program component storage unit 18.
The program component storage unit 18 is a memory or the like that stores program components in accordance with instructions from the program component registration unit 17. The program component storage unit 18 stores the program components received from the program component registration unit 17. When the component processing unit 19 performs a process of replacing the circuit module of the sequence program with a program component, the program component storage unit 18 outputs the stored program component to the component processing unit 19.
The component processing unit 19 replaces the common logic portion H in the sequence program stored in the program storage unit 12 with the program component stored in the program component storage unit 18. The component processing unit 19 stores the replaced sequence program in the program storage unit 12.
When the instruction input unit 16 sends an output instruction, the output unit 20 reads the sequence program specified by the output instruction from the program storage unit 12 and outputs the sequence program to the sequence program editing apparatus 3, which is an external apparatus. When an external device other than the sequence program editing device 3 is connected to the output unit 20, the output unit 20 outputs the sequence program specified by the output instruction to the external device specified by the output instruction.
The component definition display processing unit 21 displays a screen (corresponding to the screen 101 shown in fig. 1) for specifying the generation of the input/output parameters of the program components on the display device 5 based on the information on the common circuit pattern G transmitted from the search result display processing unit 15. The component definition display processing unit 21 receives a designation of an input/output parameter to be generated by a user in a state where a generation designation screen of the input/output parameter of the program component is displayed. If the specification of the input/output parameters to be generated by the user is finished, the component definition display processing section 21 generates definition information of the program component based on the result of the specification by the user, and transmits the generated definition information to the componentization profile image display processing section 22.
The component-created general-image display processing unit 22 creates an image (a confirmation screen) of a sequence program in which the common logical part H is replaced with a program component based on the definition information of the program component transmitted from the component definition display processing unit 21, and displays the image on the display device 5. Specifically, the component-oriented general-image display processing unit 22 causes the display device 5 to display a screen corresponding to the screen 102 shown in fig. 1. The component-based overview image display processing unit 22 receives an input of a determination result as to whether or not the replacement is actually performed from the user in a state where the replaced sequence program confirmation screen is displayed on the display device 5. The component-created-profile-image display processing unit 22, upon receiving an input indicating a result of determination to perform replacement, transmits definition information of the program component received from the component-definition display processing unit 21 to the program-component registration unit 17. On the other hand, if the component-created-profile-image display processing unit 22 receives an input indicating a determination result that replacement is not to be performed, it notifies the component-definition display processing unit 21 of the determination result. The component definition display processing unit 21 that has received the notification displays the screen for specifying the generation of the input/output parameters of the program component on the display device 5 again, and receives the specification of the input/output parameters to be generated from the user.
Fig. 3 is a flowchart showing an example of the operation of the program creation support apparatus 1 according to the embodiment. Fig. 3 is a flowchart showing a processing flow in the case where the program creation support device 1 creates a program component from a sequence program and generates a sequence program in which a common logic portion H is replaced with the program component.
The program creation support device 1 is configured to store a sequence program in the program storage unit 12. That is, the program input unit 11 of the program creation support device 1 receives the sequence program from the sequence program creation device 2, and stores the received sequence program in the program storage unit 12.
The program creation support device 1 receives the search instruction of the common logical part H, and starts the program componentization processing (step S1). That is, if a search instruction of the common circuit pattern G (common logic portion H) is input from the instruction input unit 16 by the user, the search instruction is sent from the instruction input unit 16 to the common determination unit 13. Thereby, the program creation support device 1 starts the program componentization process.
Upon receiving a search instruction from the instruction input unit 16, the common determination unit 13 extracts the common circuit pattern G from the sequence program stored in the program storage unit 12. The common determination unit 13 extracts a common logic portion H from, for example, a sequence program, and extracts a common circuit pattern G from circuit blocks (circuit blocks 2a to 4a shown in fig. 1, etc.) arranged in the common logic portion H (step S2). The common determination unit 13 checks whether or not the device assignments for the circuit components match in all the common logic sections H for each circuit component constituting the extracted common logic section H, and generates accessory information indicating the result of the check. The auxiliary information is information indicating to which of the 1 st circuit component and the 2 nd circuit component each of the circuit components constituting the common logic portion H belongs.
When the extraction of the common circuit pattern G and the generation of the accessory information are completed, the common determination unit 13 stores the configuration information and the accessory information of the extracted common circuit pattern G in the search result storage unit 14 in association with the number of the common circuit patterns G (step S3).
The common determination unit 13 transmits the position of the common logical part H to the component processing unit 19 in association with program identification information that is information for identifying the sequence program from which the common logical part H is extracted. The position of the common logic portion H is, for example, the line number of the ladder program.
The search result storage unit 14, upon receiving the information from the common determination unit 13, stores the received information. If the information output from the common determination unit 13 is stored in the search result storage unit 14, the search result display processing unit 15 displays the configuration and the number of common circuit patterns G extracted by the common determination unit 13 on the display device 5 in a list based on the information stored in the search result storage unit 14. The display device 5 displays, for example, the common circuit patterns G shown in fig. 1 and the number of the common circuit patterns G (3 in fig. 1) (step S4). Whether or not the information output from the common determination unit 13 is stored in the search result storage unit 14 is grasped by, for example, the search result display processing unit 15 periodically checking the state of the search result storage unit 14. The common determination unit 13 may notify the search result display processing unit 15 that the information is already stored in the search result storage unit 14.
After executing step S4, the program creation assistance device 1 waits for the common circuit pattern G selected by the user for componentization. Upon receiving a selection of the common circuit pattern G to be formed into parts from the user (step S5), the instruction input unit 16 generates a part designation instruction indicating the selected common circuit pattern G and transmits the instruction to the search result display processing unit 15. The search result display processing unit 15 reads the configuration information and the accessory information of the common circuit pattern G indicated by the component designation instruction from the search result storage unit 14, and transmits the configuration information and the accessory information to the component definition display processing unit 21.
Upon receiving the configuration information and the accessory information of the common circuit pattern G from the search result display processing unit 15, the part definition display processing unit 21 displays, on the display device 5, a screen for specifying the generation of the input/output parameters of the program part corresponding to the common circuit pattern G selected by the user in step S5, based on the received information (step S6). In step S6, the component definition display processing unit 21 displays, for example, the screen image of the contents shown in fig. 4 on the display device 5 as a screen image for specifying the generation of the input/output parameters of the program component. Fig. 4 is a diagram showing an example of a screen for specifying the generation of input/output parameters of a program component. The generation designation screen for the input/output parameters of the program component is displayed when the user designates the parameters generated as the input/output parameters of the program component. That is, the program creation support apparatus 1 displays the screen for specifying the generation of the input/output parameters of the program component on the display device 5 when receiving the specification of the parameters generated as the input/output parameters of the program component from the user. The screen for specifying the generation of input/output parameters (hereinafter referred to as the screen 101) of the program component illustrated in fig. 4 includes "coordinates", "circuit symbols", "coincidence/non-coincidence of device assignment", and "whether or not to generate input/output parameters". The "coordinates" show the positions of the respective circuit components included in the common circuit pattern G. The "circuit symbol" shows the kind of circuit component existing at the position shown by the "coordinates" of the same row. The "coincidence/non-coincidence of device assignment" shows whether or not the device assignment made for the circuit components existing at the positions shown by the "coordinates" of the same row coincides in all the common logic sections H. That is, "coincidence/non-coincidence of device assignment" shows to which of the 1 st circuit component and the 2 nd circuit component the circuit component existing at the position shown by the "coordinates" of the same row belongs. The circuit components (1 st circuit component) whose "match/mismatch of device assignment" is "match" are displayed together with the devices assigned to the circuit components. For example, a device assigned to a circuit component having coordinates (1, 0) is "M2". "generation or non-generation of input-output parameters" shows whether or not input-output parameters for assigning devices to circuit components existing at positions shown by "coordinates" of the same row are generated. When the screen 101 is displayed on the display device 5, the user operates an input device such as a mouse to check or remove the item "whether or not the input/output parameter is generated", thereby changing the designation of the input/output parameter to be generated. However, the generation of the input/output parameters is necessary for the circuit component (2 nd circuit component) in which "the matching/non-matching of the device assignment" is "non-matching". Therefore, the program creation support device 1 fixes "whether or not to generate the input/output parameter" of the circuit component whose "coincidence/non-coincidence in device assignment" is "non-coincidence" to a state in which the check is made, and does not receive an operation of removing the check by the user.
After step S6 is executed, the program creation support apparatus 1 waits for the user to select the input/output parameters to be generated by the program component and the end of the selection operation while displaying the screen 101 shown in fig. 4 on the display device 5. If the selection operation by the user is finished, that is, if a selection of the input/output parameter to be generated is received from the user (step S7), the instruction input unit 16 generates a parameter generation-or-not instruction indicating the selected input/output parameter and transmits it to the component definition display processing unit 21. The instruction input unit 16 generates a parameter generation or non-generation instruction when, for example, a selection operation end button, which is not shown in fig. 4, is pressed by the user. Here, the description is continued with the parameter generation/non-generation instruction being generated in accordance with the contents of the screen 101 shown in fig. 4. That is, the user designates generation of input/output parameters of the coil assigning apparatus for coordinates (2, 0), and the description is continued. In this case, the parameter generation/non-generation instruction includes information specifying generation of input/output parameters for the a-touch point assignment device for the coordinates (0, 0), the coil for the coordinates (2, 0), and the b-touch point assignment device for the coordinates (1, 1), respectively. Further, the part definition display processing section 21 and the instruction input section 16 that execute the above steps S6 and S7 constitute a selection receiving section for the user to select, from among the 1 st circuit parts, the 1 st circuit part that needs to be assigned to the device using the input/output parameters after the common logic portion H is replaced with the program part.
Upon receiving the parameter generation/non-generation instruction, the component definition display processing unit 21 transmits the received parameter generation/non-generation instruction and the configuration information of the common circuit pattern G received from the search result display processing unit 15 and stored to the componentized general-image display processing unit 22.
The component-layout-profile-image display processing unit 22, upon receiving the parameter generation/non-generation instruction and the configuration information of the common circuit pattern G from the component-definition display processing unit 21, stores the received information. Further, the component-created-profile-image display processing unit 22 causes the display device 5 to display a screen for checking the sequence program in which the common logic portion H is replaced with the program component, based on the information received from the component-definition display processing unit 21 and the sequence program stored in the program storage unit 12 (step S8). In step S8, the component-created general-image display processing unit 22 causes the display device 5 to display a screen of contents shown in fig. 5, for example, as a screen for confirming the sequence program after the replacement processing is executed. Fig. 5 is a diagram showing an example of a screen for checking the sequence program after execution of the replacement processing. The screen for confirming the sequence program after execution of the replacement process is a screen for confirming the configuration of the sequence program in which the common logic portion H is replaced with the program component. That is, the parts-by-parts general-image display processing unit 22 is a confirmation display processing unit that causes the display device 5 to display a screen for confirming the configuration of the sequence program replaced with the program parts. The sequence program confirmation screen after execution of the replacement process shown in fig. 5 (hereinafter referred to as screen 102) is configured such that the sequence program before replacement and the sequence program after replacement are arranged horizontally. The left side of the screen 102 is a sequence program (program before replacement) in which the common logic portion H is replaced with a program component, and the right side of the screen 102 is a sequence program (program after replacement) in which the common logic portion H is replaced with a program component. The component-created general-image display processing unit 22 may calculate the size of the sequence program before replacement and the size of the sequence program after replacement, and display the calculated sizes on the screen 102. In this case, the user can know in advance the effect of reducing the program size by replacing the common logic portion H with a program component, and can use it as a material for determining whether or not to perform the replacement. Fig. 5 shows an example of a screen in which the configuration of the sequence program replaced with the program component is displayed for 1 common logic portion H, but the configuration of the sequence program replaced with the program component may be displayed for a plurality of common logic portions H. The parts-by-parts general-image display processing unit 22 may scroll the display of the screen 102 up and down in accordance with an operation from the user, and may be configured to allow the user to confirm the configuration of the sequence program replaced with a program part for all the common logic portions H.
After step S8 is executed, the program creation support apparatus 1 waits for the user to select whether or not to execute replacement of the common logical section H by the program component while displaying the screen 102 shown in fig. 5 on the display apparatus 5 (step S9). If the "OK" button on the lower right of the screen 102 is pressed, that is, if execution of replacement of the common logical part H by the program component is selected (step S9: execution), the instruction input unit 16 generates a componentization determination instruction and transmits the instruction to the componentization-profile-image display processing unit 22. In addition, if the "cancel" button in the lower right of the screen 102 is pressed, that is, if the replacement of the common logical part H by the program component is not performed is selected (step S9: cancel), the instruction input unit 16 generates a cancel instruction and transmits it to the componentized-profile-image-display processing unit 22.
Upon receiving the cancel instruction, the component-created-profile-image-display processing unit 22 transmits the received cancel instruction to the component-definition-display processing unit 21, and ends the display of the screen 102 on the display device 5. The component definition display processing unit 21 causes the screen 101 to be displayed on the display device 5 when receiving a cancel instruction via the componentized general-image display processing unit 22. Then, the component definition display processing unit 21 waits again for the user to select the input/output parameter to be generated of the program component and end the selection operation. In this way, in the case where the "cancel" button in the lower right of the screen 102 shown in fig. 5 is pressed by the user, the program creation assistance apparatus 1 returns to step S7.
On the other hand, if the component-formation-determination instruction is received, the component-formation-profile-image display processing unit 22 transmits information received from the component-definition display processing unit 21 and stored therein, specifically, a parameter generation/non-generation instruction and configuration information of the common circuit pattern G to the program component registration unit 17.
The program component registration section 17, if receiving the parameter generation necessity/unnecessity instruction and the configuration information of the common circuit pattern G from the componentization-profile-image display processing section 22, converts the common circuit pattern G selected in step S5 into a program component (step S10). Specifically, the program component registration unit 17 creates a program component by converting the common circuit pattern G indicated by the configuration information of the common circuit pattern G received from the componentization-profile-image display processing unit 22 into a program component having input/output parameters indicated by the parameter generation/non-generation instruction. The program component registration section 17 stores the converted program component in the program component storage section 18 (step S11). In this way, the common circuit pattern G selected by the user is stored as a program component in the program component storage unit 18.
The program component storage unit 18 stores the received program component if the program component is received from the program component registration unit 17. If the program components created by the program component registration unit 17 are stored in the program component storage unit 18, the componentization processing unit 19 replaces the common logical part H existing in the sequence program stored in the program storage unit 12 with the program components stored in the program component storage unit 18 (step S12). When the common logic portion H is replaced with a program component, the component processing unit 19 allocates input/output parameters of the replaced program component. At this time, the component processing unit 19 replaces the common logical part H of the sequence program indicated by the program identification information with the program component based on the information received and stored from the common determination unit 13, specifically, based on the position of the common logical part H and the program identification information of the sequence program from which the common logical part H is extracted. Specifically, the component processing unit 19 extracts a sequence program to be subjected to component processing from the program storage unit 12 based on the program identification information. The component processing unit 19 replaces the circuit pattern existing in the common logic portion H of the extracted sequence program with the program component stored in the program component storage unit 18. Whether or not a program component is stored in the program component storage unit 18 is grasped by periodically checking the state of the program component storage unit 18 by the component processing unit 19, for example. The program component registration unit 17 may notify the component processing unit 19 that the program component is already stored in the program component storage unit 18.
After at least a part of the sequence program is replaced with the program component, the replaced sequence program is stored in the program storage unit 12. Then, if the user inputs an output instruction to the instruction input section 16, the output instruction is transmitted from the instruction input section 16 to the output section 20. The output unit 20 extracts the sequence program specified by the output instruction from the program storage unit 12 and transmits the sequence program to the sequence program editing apparatus 3. Thus, the sequence program editing apparatus 3 edits the sequence program in accordance with the instruction of the user.
After step S12 of fig. 3 is executed, the program creation support device 1 may return to step S4 and continue the operation. In this case, when the search result display processing unit 15 displays the configuration and the number of the common circuit patterns G on the display device 5 in a list in step S4, the common circuit patterns G selected in step S5 executed in the past, that is, the common circuit patterns G whose parts have been formed into program parts are not included in the list.
In the present embodiment, the common circuit pattern G specified by the user is formed into components, but the program component registration unit 17 may form all the common circuit patterns G extracted by the common determination unit 13 into components. In this case, the program creation assistance device 1 repeatedly executes the processing of steps S6 to S9 shown in fig. 3, for example, and executes steps S10 to S12 if the processing of steps S6 to S9 ends for all the common circuit patterns G.
In the present embodiment, the program creation support apparatus 1 causes the user to select the input/output parameters of the program components in steps S6 and S7, but may be configured not to receive a selection made by the user. That is, circuit components (1 st circuit component) that are identical in all the common logic portions H may be assigned to devices among the circuit components included in the common circuit pattern G, and the number of input/output parameters of the program components may be minimized without generating input/output parameters. In this case, the program creation assistance apparatus 1 executes step S10 after step S5 described above. At this time, the search result display processing unit 15 reads the configuration information and the accessory information of the common circuit pattern G selected by the user in step S5 from the search result storage unit 14, and transmits the configuration information and the accessory information to the program component registration unit 17.
In the present embodiment, an example is described in which the sequence program to be processed by the program creation support device 1 is a ladder program, but the sequence program is not limited to the ladder program.
In addition, the program creation support apparatus 1 may be configured to specify the size of the block extracted as the common circuit pattern G by the user, as in the invention described in patent document 1.
As described above, the program creation support device 1 according to the present embodiment analyzes a sequence program to check whether or not a plurality of circuit patterns having the same structure exist, extracts a common circuit pattern G that is a circuit pattern having the same structure, and generates a program component indicating the extracted common circuit pattern G. Then, the program creation support device 1 replaces the common circuit pattern G included in the sequence program with the generated program component. After extracting the common circuit pattern G, the program creation assisting apparatus 1 checks whether or not the device assignments match each other among all the extracted common circuit patterns G for each of the circuit components included in the common circuit pattern G, and generates auxiliary information indicating the result of the check. When the program component is generated, the program creation support device 1 assigns the 1 st circuit component that matches all the common circuit patterns G to the devices, and does not generate the input/output parameters for device assignment except when instructed by the user. This can reduce the number of input/output parameters of the program component. As a result, readability and maintainability of the sequence program can be improved.
Next, a hardware configuration of the program creation support apparatus 1 will be explained. Fig. 6 is a diagram showing a hardware configuration of the program creation support apparatus 1 according to the embodiment.
