Abstract
Description
Technical Field
[0001] This invention relates to the field of industrial control, and in particular to a method, apparatus, device, and storage medium for calling function blocks in industrial control configuration software. Background Technology
[0002] With the deepening application of industrial control systems, when facing larger-scale and more complex control systems, people have gradually realized that the original host computer programming development method is time-consuming, labor-intensive, and unprofitable for projects. At the same time, the widespread application of management information systems and computer-integrated manufacturing systems requires more detailed and in-depth data for production, operation, and decision-making in industrial enterprises to optimize various aspects of production and operation. Therefore, in recent years, the application of configuration software has gradually become more widespread in China. The process from configuring logic to running it in the controller is a core issue in a control system. In existing technologies, after IEC configuration is completed, the IEC logic needs to be downloaded to the controller. Some software converts the IEC logic into a syntax tree, and then converts the syntax tree into binary code before downloading it to the controller. Converting IEC logic to a syntax tree has two main drawbacks: first, converting a simple configuration logic into a syntax tree generates many nodes, making it difficult to view; second, converting to a syntax tree does not enable breakpoint debugging. Summary of the Invention
[0003] In view of this, the purpose of this invention is to provide a method, apparatus, device, and storage medium for calling function blocks in industrial control configuration software, which can solve the problems of storing and calling function blocks when converting IEC logic into C language. The specific solution is as follows:
[0004] In a first aspect, this application discloses a method for calling function blocks in industrial control configuration software, including:
[0005] Based on preset storage rules, the addresses of local variables of the target function block in the industrial control configuration software are stored using the target structure to complete the storage of the target function block.
[0006] Obtain the structure variable corresponding to the target function block, and write the value of the structure variable based on the configuration logic;
[0007] The target function block is converted into C language to obtain the corresponding .c file. The C functions in the .c file are then called so that the .c file is compiled into a controller executable file by the compilation module. Based on the controller executable file, the industrial controller calls the target function block to complete the corresponding industrial control process.
[0008] Optionally, the step of storing the addresses of local variables of the target function block in the industrial control configuration software using the target structure based on preset storage rules to complete the storage of the target function block includes:
[0009] Establish a one-to-one correspondence between the structure variables of the target structure and the local variables of the target function block, and store the local variables of the target function block based on the one-to-one correspondence and the address of the target structure.
[0010] Optionally, writing values to the structure variables based on configuration logic further includes:
[0011] If the input and output variables of the target function block are not assigned values in the configuration logic, then the structure variables will not be written to and will be set to default values.
[0012] Optionally, converting the target function block into C language to obtain the corresponding .c file includes:
[0013] The target function block is converted into C language to obtain the corresponding target header file (.c file) associated with the target function block.
[0014] Optionally, the target header files associated with the target function block include: the header file corresponding to the target function block and the header files corresponding to the functions called by the logic of the target function block.
[0015] Optionally, converting the target function block into C language to obtain the corresponding .c file includes:
[0016] The target function block is converted into C language to obtain the corresponding .c file. The C function in the .c file is a function with an empty return value and input parameters of the structure variable corresponding to the target function block and the forced address offset.
[0017] Optionally, the forced address offset includes: forcing a relative offset between the address of the tag storage and the variable address.
[0018] Secondly, this application discloses a function block calling device for industrial control configuration software, comprising:
[0019] The function block storage module is used to store the addresses of local variables of the target function block in the industrial control configuration software based on the target structure according to the preset storage rules, so as to complete the storage of the target function block;
[0020] The variable write-value module is used to obtain the structure variable corresponding to the target function block and write the value of the structure variable based on the configuration logic;
[0021] The function call module is used to convert the target function block into C language to obtain the corresponding .c file, and to call the C functions in the .c file so that the .c file can be compiled into a controller executable file by the compilation module. Based on the controller executable file, the industrial controller can call the target function block to complete the corresponding industrial control process.
[0022] Thirdly, this application discloses an electronic device, including:
[0023] Memory, used to store computer programs;

[0025] Fourthly, this application discloses a computer-readable storage medium for storing a computer program, which, when executed by a processor, implements the aforementioned function block calling method of industrial control configuration software.
[0026] As can be seen from the above, when calling function blocks in industrial control configuration software, this application first uses a target structure to store the addresses of local variables of the target function block in the industrial control configuration software based on preset storage rules, thereby completing the storage of the target function block; it then obtains the structure variable corresponding to the target function block and writes values to the structure variable based on the configuration logic; finally, it converts the target function block into C language to obtain a corresponding .c file, and calls the C functions in the .c file so that the .c file generates a controller executable file through the compilation module, and the industrial controller calls the target function block based on the controller executable file to complete the corresponding industrial control process. It is evident that, compared with converting to C syntax, converting to C is easier to view, more concise, and can be debugged in Visual Studio, offering advantages such as cross-platform compatibility and ease of maintenance.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0035] In existing technologies, after IEC configuration is completed, the IEC logic needs to be downloaded to the controller. Some software converts the IEC logic into a syntax tree, and then converts the syntax tree into binary code before downloading it to the controller. Converting IEC logic to a syntax tree has two main drawbacks: first, converting a simple configuration logic into a syntax tree generates many nodes, making it difficult to view; second, converting to a syntax tree does not enable breakpoint debugging. To solve this problem, this application provides a function block calling method for industrial control configuration software, which solves the problems of function block storage and calling when converting IEC logic into more easily viewable and concise C language.
[0036] See Figure 1 As shown in the figure, an embodiment of the present invention discloses a method for calling function blocks in industrial control configuration software, including:
[0037] Step S11: Based on preset storage rules, use the target structure to store the addresses of local variables of the target function block in the industrial control configuration software, so as to complete the storage of the target function block.
[0038] In this embodiment, the local variables of the function block include input variables, output variables, input-output variables, and internal variables. Since the addresses of these local variables are not contiguous, it is impossible to access all pins of the function block through a single address. Therefore, it is necessary to use a target structure based on preset storage rules to store the addresses of the local variables of the target function block in the industrial control configuration software, thereby completing the storage of the target function block.
[0039] Step S12: Obtain the structure variable corresponding to the target function block, and write the value of the structure variable based on the configuration logic.
[0040] In this embodiment, a function block not only needs to store the values of each pin, but also needs to execute certain logic to obtain the corresponding results. When configuring the logic for a function block call in the control software, such as... Figure 2 As shown, firstly, the structure variable corresponding to the function block is obtained, and then values are written to each member of the structure variable according to the configuration logic. The step of writing values to the structure variable based on the configuration logic further includes: if the input and output variables of the target function block are not assigned values in the configuration logic, then no values are written to the structure variable, and default values are adopted.
[0041] Step S13: Convert the target function block into C language to obtain the corresponding .c file, and call the C functions in the .c file so that the .c file generates a controller executable file through the compilation module, and realize the industrial controller to call the target function block based on the controller executable file to complete the corresponding industrial control process.
[0042] In this embodiment, the target function block is converted into C language to obtain the corresponding .c file of the target header file associated with the target function block. The target header file associated with the target function block includes: the header file corresponding to the target function block and the header files corresponding to the functions called by the logic of the target function block. Then, by calling the C functions in the .c file, the .c file is compiled into a controller executable file by the compilation module. Based on the controller executable file, the industrial controller calls the target function block to complete the corresponding industrial control process.
[0043] As can be seen from the above, when calling function blocks in industrial control configuration software, this application first uses a target structure to store the addresses of local variables of the target function block in the industrial control configuration software based on preset storage rules, thereby completing the storage of the target function block; it then obtains the structure variable corresponding to the target function block and writes values to the structure variable based on the configuration logic; finally, it converts the target function block into C language to obtain a corresponding .c file, and calls the C functions in the .c file so that the .c file generates a controller executable file through the compilation module, and the industrial controller calls the target function block based on the controller executable file to complete the corresponding industrial control process. It is evident that, compared with converting to C syntax, converting to C is easier to view, more concise, and can be debugged in Visual Studio, offering advantages such as cross-platform compatibility and ease of maintenance. This application primarily addresses the problems of function block storage and function block calling when converting IEC logic to C language.
[0044] See Figure 3 As shown in the figure, this invention discloses a specific method for calling function blocks in industrial control configuration software, including:
[0045] Step S21: Establish a one-to-one correspondence between the structure variables of the target structure and the local variables of the target function block, and store the local variables of the target function block based on the one-to-one correspondence and the address of the target structure.
[0046] In this embodiment, a structure is used to store the addresses of local variables of the function block. Each member of the structure corresponds one-to-one with a local variable of the function block, and all members are pointers. The correspondence rules are as follows: Figure 4 As shown. In a specific embodiment, assuming that its inputs, outputs, input-output pairs, and local variables are all of type BOOL, and their names are in, out, inout, and temp respectively, then its storage format is as follows (to prevent the variable names from leading with numbers during configuration, __AT__ is uniformly added before the names):
[0047] struct__AT__FB001
[0048] {
[0049] bool*H_IN;
[0050] bool*H_OUT;
[0051] bool*H_INOUT;
[0052] bool*H_TEMP;
[0053] }
[0054] This structure is defined in the .h file corresponding to the FB001 function block.
[0055] Step S22: Obtain the structure variable corresponding to the target function block, and write the value of the structure variable based on the configuration logic.
[0056] Step S23: Convert the target function block into C language to obtain the corresponding .c file. The C function in the .c file is a function with an empty return value and input parameters being the structure variable corresponding to the target function block and the forced address offset.
[0057] In this embodiment, the logic of the function block, after being converted to C, corresponds to a .c file. Taking FB001 as an example again, this .c file contains the following: the header files that need to be referenced, including the header files corresponding to the function block itself and the header files corresponding to the functions called in the function block logic, and a function named H_FB001, with the variable __AT__FB001 as input parameter and a forced address offset. The forced address offset includes: the relative offset between the address of the forced marker storage and the address of the variable. It should be noted that the content of this function is the internal logic of the function block, and the return value is empty. Furthermore, the H_FB001 function body internally implements the updating of output and input / output variables.
[0058] Step S24: By calling the C functions in the .c file, the .c file is compiled into a controller executable file by the compilation module, and the industrial controller calls the target function block based on the controller executable file to complete the corresponding industrial control process.
[0059] The specific processes of steps S22 and S24 can be found in the relevant content disclosed in the foregoing embodiments, and will not be repeated here.
[0060] As can be seen from the above, when calling function blocks in industrial control configuration software, this application first establishes a one-to-one correspondence between the structure variables of the target structure and the local variables of the target function block, and stores the addresses of the local variables of the target function block based on the one-to-one correspondence and the target structure; obtains the structure variables corresponding to the target function block, and writes values to the structure variables based on the configuration logic; converts the target function block into C language to obtain the corresponding .c file, and the C functions in the .c file are functions with empty return values and input parameters of the structure variables corresponding to the target function block and forced address offsets. Finally, by calling the C functions in the .c file, the .c file generates a controller executable file through the compilation module, and the industrial controller calls the target function block based on the controller executable file to complete the corresponding industrial control process. It is evident that, compared with converting to C syntax, converting to C is easier to view, more concise, and can be debugged in Visual Studio, offering advantages such as cross-platform compatibility and ease of maintenance. This application focuses on solving the problems of function block storage and function block calling when converting IEC logic into C language.
