[0002] The controller in the industrial control system is usually an embedded device, and the configuration software runs on the host computer. Through the host computer configuration software, users can use industrial programming languages ​​(for example, IEC 61131-3 language) to configure and program the control logic. After completing the logic configuration and obtaining the target program, the target program needs to be compiled into an executable program and downloaded to the controller device for execution.

[0003] The target program of each task usually consists of multiple Programming Organization Units (POUs). However, traditional compilation requires all program organization units to be fully compiled and linked to generate a complete executable program. This method requires the entire executable program to be downloaded each time, including all referenced POUs, regardless of whether these POUs have actually changed. This not only increases the complexity of the downloaded data, but also significantly increases the download time, reducing development efficiency and system response speed. Summary of the invention

[0023] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.

[0024] A method and device for running a target program according to an embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0025] Figure 1 This is a method for running a target program provided by an embodiment of the present application, such as Figure 1 As shown, the method includes:

[0026] S101, obtaining a target program including at least two program organization units, and determining at least one target program organization unit from the target program;

[0027] S102, compile each target program organization unit to obtain an executable file corresponding to each target program organization unit;

[0028] S103, generating a symbol table file corresponding to each target program organization unit according to each executable file, wherein the symbol table file contains a jump address corresponding to the symbol in the executable file;

[0029] S104: Download the executable file and the symbol table file to the controller, so that when the controller executes the executable file, it determines the jump address through the symbol table file to jump and run.

[0030] It can be understood that the target program operation method provided in the present application is applied to a host computer, the configuration software belongs to the host computer, and the host computer configuration software uses an industrial programming language to perform logic configuration programming to obtain the target program.

[0031] It can be understood that the present application does not limit the types of the above-mentioned industrial programming languages. The industrial programming language only needs to conform to the standards of the programming systems of programmable logic controllers (PLC), DCS, IPC, CNC, and SCADA. Exemplarily, the industrial programming language is the IEC61131-1 language. The types of industrial programming languages ​​include ST, SFC, LD, FBD, etc.

[0032] It can be understood that the program organization unit is the basic programming unit in industrial programming languages. POU consists of three types of basic units: program, function block, and function.

[0033] It can be understood that if the target program contains only one program organization unit, then each time it is downloaded, it is necessary to compile and link this program organization unit. There is no problem proposed in the present application that all program organization units in the target program need to be compiled to generate an executable program and then downloaded to the controller, resulting in a large amount of downloaded data and low download efficiency.

[0034] Based on the above reasons, if the target program contains only one program organization unit, the program organization unit can be directly compiled and downloaded; if the target program contains at least two program organization units, then after obtaining the target program, this application will determine at least one target program organization unit from the target program, and the target program organization unit is the program organization unit that needs to be compiled and downloaded to the controller subsequently.

[0035] Exemplarily, if there are three program organization units A, B, and C in the target program, the present application determines at least one target program unit from the three program organization units A, B, and C, and the target program unit can be at least one of the A program organization unit, the B program organization unit, and the C program organization unit.

[0036] In some examples, after determining the target program organization unit, the present application will compile each target program organization unit to obtain the executable file corresponding to each target program organization unit, and the program organization units that are not the target program organization units will not be processed; specifically, if there are three program organization units A, B, and C in the target program, and it is determined that the B and C program organization units are respectively a target program organization unit, then the B program organization unit and the C program organization unit are compiled respectively to obtain the executable file corresponding to the B program organization unit and the executable file corresponding to the C program organization unit, and before the A program organization unit is determined as the target program organization unit, the A program organization unit will not be compiled.

[0037] The above method determines the target program organization unit from the target program, and subsequently only compiles the target program organization unit, thereby improving the compilation speed and avoiding the problem of slowing down the compilation speed caused by directly compiling all program organization units.

[0038] In some examples, after obtaining the executable file corresponding to each target program organization unit, the present application will also generate a symbol table file corresponding to each target program organization unit based on each executable file, and the symbol table file contains the jump address corresponding to the symbol in the executable file (the address where the program is actually loaded + the relative offset address); illustratively, if there are N executable files, N symbol table files are generated; specifically, if there are three program organization units A, B, and C in the target program, and it is determined that the B and C program organization units are respectively a target program organization unit, then the B program organization unit and the C program organization unit are compiled respectively to obtain the B executable file corresponding to the B program organization unit and the C executable file corresponding to the C program organization unit, and subsequently generate the B symbol table file according to the B executable file and the C symbol table file according to the C executable file.

[0039] After generating the symbol table file, the present application downloads the executable file and the symbol table file to the controller, so that the controller executes the executable file by determining the jump address through the symbol table file to jump and run; specifically, taking the target program as an example, in which three program organization units A, B, and C are included, and it is determined that the B and C program organization units are respectively a target program organization unit, then the B program organization unit and the C program organization unit are respectively compiled to obtain the B executable file corresponding to the B program organization unit, and to obtain the C executable file corresponding to the C program organization unit, and then the B symbol table file is generated according to the B executable file, and the C symbol table file is generated according to the C executable file, and then the B executable file, the C executable file, the B symbol table file, and the C symbol table file are respectively downloaded to the controller, and when the controller executes the B executable file, the address corresponding to the symbol in the B executable file is searched through the B symbol table file, so as to jump and run, and when the controller executes the C executable file, the address corresponding to the symbol in the C executable file is searched through the C symbol table file, so as to jump and run.

[0040] According to the technical solution provided in the embodiment of the present application, a target program including at least two program organization units is obtained, and at least one target program organization unit is determined from the target program; each target program organization unit is compiled to obtain an executable file corresponding to each target program organization unit; a symbol table file corresponding to each target program organization unit is generated according to each executable file, and the symbol table file contains a jump address corresponding to the symbol in the executable file; the executable file and the symbol table file are downloaded to a controller, so that when the controller executes the executable file, the jump address is determined by the symbol table file to jump and run. The present application only compiles the target program organization unit, avoids compiling all program organization units, and improves the compilation speed. Subsequently, a symbol file table is generated through the executable file corresponding to each target program organization unit, so that the controller can execute the executable file according to the corresponding symbol file table, thereby realizing the separate operation of each executable file, avoiding the problem in the related art that all program organization units in the target program need to be compiled to generate an executable program and then downloaded to the controller, resulting in a large amount of downloaded data and low download efficiency.

[0041] In some embodiments, Figure 2 As shown, the method also includes:

[0042] S201, if any target program organization unit is updated, generating a new executable file according to the updated target program organization unit;

[0043] S202: Generate a new symbol table file corresponding to the updated target program organization unit according to the new executable file, and download the new symbol table file and the new executable file to the controller.

[0044] It can be understood that when the user modifies a single (or multiple) POUs, only the compiled instructions of the modified POU are downloaded when downloading to the controller, and the unmodified POU program does not need to be downloaded, thereby reducing the downloaded data and improving the download speed. At the same time, it solves the problem that after the user modifies a single POU due to slow compilation and linking, the download of the single POU requires a long compilation process, resulting in the user being unable to submit the modified POU online in real time. This realizes the single-point download of the control logic configuration software based on compilation and execution when the configuration software is online.

[0045] It can be understood that if the user updates any target program organization unit, the present application will generate a new executable file based on the updated target program organization unit; based on the new executable file, a new symbol table file corresponding to the updated target program organization unit is generated, and the new symbol table file and the new executable file are downloaded to the controller.

[0046] For example, taking the target program including three program organization units A, B, and C as an example, and determining that the B and C program organization units are respectively a target program organization unit, the B program organization unit and the C program organization unit are respectively compiled to obtain the B executable file corresponding to the B program organization unit, and the C executable file corresponding to the C program organization unit. Subsequently, a B symbol table file is generated according to the B executable file, and a C symbol table file is generated according to the C executable file. Subsequently, the B executable file, the C executable file, the B symbol table file, and the C symbol table file are respectively downloaded to the controller. When the controller executes the B executable file, the B symbol table file is used to search for the symbol table file in the B executable file. The address corresponding to the symbol is found, so as to jump and run. When the controller executes the C executable file, the address corresponding to the symbol in the C executable file is searched through the C symbol table file, so as to jump and run. If the B program organization unit is updated subsequently, a new B executable file is generated according to the updated B program organization unit, and then a new B symbol table file corresponding to the updated B program organization unit is generated according to the new B executable file, and the new B symbol table file and the new B executable file are downloaded to the controller, thereby realizing single-point downloading, avoiding the need to recompile and link all the program organization units in the target program, resulting in excessive downloading data volume and low downloading efficiency.

[0047] In some examples, if the program organization unit in the target program is adjusted to a target program organization unit, a new executable file is also generated according to the new target program organization unit, and a new symbol table file corresponding to the updated target program organization unit is generated according to the new executable file, and the new symbol table file and the new executable file are downloaded to the controller. Exemplarily, taking the target program as an example, in which three program organization units A, B, and C are included, and it is determined that the B and C program organization units are respectively a target program organization unit, the B program organization unit and the C program organization unit are respectively compiled to obtain the B executable file corresponding to the B program organization unit, and the C executable file corresponding to the C program organization unit. Subsequently, a B symbol table file is generated according to the B executable file, and a C symbol table file is generated according to the C executable file. Subsequently, the B executable file, the C executable file, the B symbol table file, and the C symbol table file are respectively downloaded to the controller. When the controller executes the B executable file, the B symbol table file is searched The address corresponding to the symbol in the B executable file is searched for in the C executable file, thereby jumping to the execution. When the controller executes the C executable file, the address corresponding to the symbol in the C executable file is searched through the C symbol table file, thereby jumping to the execution. If the A program organization unit is subsequently adjusted to the target program organization unit, the A program organization unit is compiled to obtain the A executable file corresponding to the A program organization unit. Subsequently, the A symbol table file is generated according to the A executable file, and then the A executable file and the A symbol table file are respectively downloaded to the controller. When the controller executes the A executable file, the address corresponding to the symbol in the A executable file is searched for through the A symbol table file, thereby jumping to the execution.

[0048] For example, Figure 3 As shown, the user can modify a single POU in the target program. After the modification is completed, the single POU is compiled to obtain an executable file corresponding to the single POU, and then the executable file and the corresponding symbol table file are downloaded to the controller for operation.

[0049] According to the technical solution provided in the embodiment of the present application, if any target program organization unit is updated, a new executable file is generated according to the updated target program organization unit; according to the new executable file, a new symbol table file corresponding to the updated target program organization unit is generated, and the new symbol table file and the new executable file are downloaded to the controller. When the POU is updated, the present application realizes the single-point download of the POU, avoiding the problem of low compilation and downloading efficiency caused by the need to compile, link, and download the entire target program when the POU is updated.

[0050] In some embodiments, Figure 4 As shown, each target program organization unit is compiled to obtain an executable file corresponding to each target program organization unit, including:

[0051] S401, converting the target program organization unit into a programming language file corresponding to a preset programming language;

[0052] S402: Compile the programming language file to obtain an executable file.

[0053] Specifically, the preset programming language includes but is not limited to one of C language and C++ language. The preset programming language being C language is taken as an example below.

[0054] like Figure 5 As shown, the user uses IEC language for configuration, and the configuration unit is POU. After determining the target program organization unit, this application converts the above target program organization unit into a programming language file corresponding to C language, and then compiles the programming language file to obtain a .o executable file.

[0055] It can be understood that those skilled in the art can flexibly select a C language compiler to compile a programming language file corresponding to the C language into a .o executable file.

[0056] According to the technical solution provided in the embodiment of the present application, the target program organization unit is converted into a programming language file corresponding to a preset programming language; the programming language file is compiled to obtain an executable file. The present application realizes immediate compilation of the target program organization unit to obtain an executable file.

[0057] In some embodiments, Figure 6 As shown, according to each executable file, a symbol table file corresponding to each target program organization unit is generated, including:

[0058] S601, parsing the executable file to obtain debugging information;

[0059] S602: Obtain a symbol file corresponding to the programming language file, determine a mapping relationship between symbols in the symbol file and binary instruction addresses according to the debugging information and the symbol file, and generate a symbol table file based on the mapping relationship.

[0060] Specifically, when the target program organization unit is converted into a programming language file corresponding to a preset programming language, the present application will generate a symbol file corresponding to the programming language; for example, Figure 5 As shown, taking the programming language as C language as an example, when the target program organization unit is converted into a C language file, a symbol file in the C code will be generated.

[0061] Then this example generates a symbol table file based on the .o executable file and the symbol file. Specifically, this application will parse the executable file to obtain debugging information; then obtain the symbol file corresponding to the programming language file, determine the mapping relationship between the symbols in the symbol file and the binary instruction address based on the debugging information and the symbol file, and generate a symbol table file based on the mapping relationship.

[0062] For example, Figure 7 As shown, the present application provides a linker, which parses the debugging information of the current file from the .o file, obtains the jump address of the symbol generated when the POU is converted into a C language programming file from the debugging information, and then generates a symbol table file for downloading and running; wherein, the linker directly obtains the code segment from the .o executable file, and does not involve various program instruction sets, wherein there are also various open source tools that can be directly used to copy the code segment; such as Figure 8 As shown, when the executable file is downloaded to the controller and run, the downloaded executable file is loaded and the symbol table file corresponding to the executable file is loaded; when the executable file is executed, the symbols of other executable files are called and generated when other executable files are loaded; the symbol table file of the current executable file can be used to call other executable files and can also be used to call the current executable file itself; when the executable file is running, the address corresponding to the symbol in the executable file is searched through the symbol table file, so as to jump and run.

[0063] It is understandable that C language / C++ language, as a commonly used programming language and embedded language, can run well in embedded controllers with high operating efficiency. EC language is converted to C language, and a variety of free and open source C code compilers can be used to solve the problem of great difficulty in developing and maintaining compilers. The input of the linker provided by the present application is only the .o executable file and the corresponding symbol file to be processed, and does not involve various problems of traditional linkers. It only needs to parse to obtain debugging information and copy code segments, avoiding the need to input all .o executable files during full linking, which leads to the high time-consuming disk seek and IO when searching for many .o executable files. It only needs to process the .o executable file generated by the modified (or updated, specified) POU, and only a single POU is required during downloading. The program can be freely loaded in the free memory space at runtime, and the symbol table file is loaded. When the executable file is running, the corresponding instruction address (the actual loaded address of the program + the relative offset address) is found from the symbol table file to complete the jump. The multi-task of the present application can share the code area, thereby avoiding the process of linking each task during multi-tasking. There is no need to load multiple copies of code for the same POU according to the task during runtime, which greatly reduces the occupation of the code area and saves the occupation of memory space. This solution solves many disadvantages of the existing solutions.

[0064] According to the technical solution provided in the embodiment of the present application, the executable file is parsed to obtain debugging information; the symbol file corresponding to the programming language file is obtained, and the mapping relationship between the symbols in the symbol file and the binary instruction addresses is determined based on the debugging information and the symbol file, and a symbol table file is generated based on the mapping relationship. The present application realizes the generation of a symbol table file for an executable file.

[0065] In some embodiments, Fig. 9 As shown, determining at least one target program organization unit from the target program includes:

[0066] S901, obtaining a target determination instruction;

[0067] S902: Determine a target program organization unit from at least two program organization units of the target program according to the target determination instruction.

[0068] Specifically, when the user needs to debug one or more POUs or needs to use one or more POUs, the user can issue a target determination instruction, which is used to specify a program organization unit from the target program as a target program organization unit.

[0069] For example, taking the target program containing three program organization units A, B, and C as an example, if the user needs to debug program organization unit A, then input a target determination instruction to use program organization unit A as the target organization unit, and the host computer subsequently uses program organization unit A as the target organization unit according to the target determination instruction.

[0070] According to the technical solution provided in the embodiment of the present application, a target determination instruction is obtained; a target program organization unit is determined from at least two program organization units of the target program according to the target determination instruction. The present application realizes accurate determination of the target program organization unit.

[0071] In some embodiments, Fig.10 As shown, before downloading the executable file and the symbol table file to the controller, the method further includes:

[0072] S1001. Obtain industrial control requirements;

[0073] S1002. Perform logic configuration programming according to industrial control requirements to obtain a target program.

[0074] Specifically, the user outputs industrial control requirements according to the actual effect that the industrial control wants to achieve, and performs logic configuration programming according to the industrial control requirements to obtain the target program.

[0075] It can be understood that after the logic configuration programming is performed by the host computer configuration software using the IEC61131-3 language, the configuration software compiles it into an executable file in units of tasks and downloads it to the controller device to run in the controller.

[0076] According to the technical solution provided in the embodiment of the present application, industrial control requirements are obtained; logical configuration programming is performed according to the industrial control requirements to obtain a target program, thereby realizing the construction of the target program.

[0077] All the above optional technical solutions can be arbitrarily combined to form optional embodiments of the present application, which will not be described one by one here.

[0078] The following is an embodiment of the device of the present application, which can be used to execute the embodiment of the method of the present application. For details not disclosed in the embodiment of the device of the present application, please refer to the embodiment of the method of the present application.

[0079] This embodiment also provides a target program running device, such as Fig.11 As shown, the device comprises:

[0082] A generating module 1103 is used to generate a symbol table file corresponding to each target program organization unit according to each executable file, wherein the symbol table file contains jump addresses corresponding to symbols in the executable file;

[0083] The download module 1104 is used to download the executable file and the symbol table file to the controller, so that when the controller executes the executable file, it determines the jump address through the symbol table file to jump and run.

[0084] In some examples, the compilation module 1102 is also used to generate a new executable file based on the updated target program organization unit when any target program organization unit is updated; the generation module 1103 is also used to generate a new symbol table file corresponding to the updated target program organization unit based on the new executable file, and download the new symbol table file and the new executable file to the controller.

[0087] In some examples, the determination module 1101 is further used to obtain a target determination instruction; and determine a target program organization unit from at least two program organization units of the target program according to the target determination instruction.

[0088] In some examples, the determination module 1101 is also used to obtain industrial control requirements; perform logic configuration programming according to the industrial control requirements to obtain a target program.

The present application only compiles the target program organization unit, avoids compiling all program organization units, and improves the compilation speed. Subsequently, a symbol file table is generated through the executable file corresponding to each target program organization unit, so that the controller can execute the executable file according to the corresponding symbol file table, thereby realizing the separate operation of each executable file, avoiding the problem in the related art that all program organization units in the target program need to be compiled to generate an executable program and then downloaded to the controller, resulting in a large amount of downloaded data and low download efficiency.
