The following uses electronic devices as the execution subject as an example to illustrate the following embodiments of the present application.

[0049] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0050] Please refer to Figure 1 , Figure 1 A flowchart of the first embodiment of the Modbus protocol maintenance method of the present application is provided.

[0051] The present application proposes a Modbus protocol maintenance method of a first embodiment, comprising steps S100 to S200:

[0052] Step S100, after detecting that a Modbus protocol maintenance event is triggered based on the Modbus protocol data of the target device in the target Excel file, calling a Modbus protocol maintenance macro preset in the target Excel file to generate a Modbus protocol maintenance file of the target device according to the Modbus protocol data, wherein the Modbus protocol maintenance file includes a Modbus protocol source code file, a Modbus protocol configuration file, and a Modbus protocol description document;

[0053] Step S200, based on the Modbus protocol maintenance file, performing Modbus protocol maintenance on the target device, wherein the Modbus protocol maintenance includes Modbus protocol source code maintenance, Modbus protocol configuration parameter maintenance, and Modbus protocol description document maintenance;

[0054] Among them, the Modbus protocol source code file is used to perform Modbus protocol source code maintenance on the target device, the Modbus protocol configuration file is used to perform Modbus protocol configuration parameter maintenance on the target device, and the Modbus protocol description document is used to perform Modbus protocol description document maintenance on the target device.

[0055] It should be noted that the Modbus protocol source code refers to the source code of the Modbus protocol, that is, a set of programming codes that implement the Modbus protocol functions, mainly including the code for initializing the serial communication port, the function for processing the received Modbus request and responding according to the request type, the function for writing and reading register values, the code snippets for error handling and logging, etc. Modbus protocol configuration parameters refer to the configuration parameters of the Modbus protocol, that is, the configurable parameters that affect the Modbus communication behavior, including but not limited to the baud rate, the number of data bits, parity, stop bits, timeout, address mapping, etc. Modbus protocol description documents refer to the description documents of the Modbus protocol, that is, the documents provided to users or developers, mainly including configuration guides, function descriptions, troubleshooting, version history and other description information (that is, Modbus protocol description information), which can help maintenance personnel understand and maintain the Modbus protocol and improve the accuracy and efficiency of Modbus protocol maintenance.

[0056] Those skilled in the art will know that Modbus protocol maintenance refers to the maintenance of the Modbus protocol, which aims to ensure that the device can continue to communicate stably through the Modbus protocol, reduce problems caused by communication failures, and improve the reliability and efficiency of the system. Specifically, Modbus protocol maintenance includes Modbus protocol source code maintenance, Modbus protocol configuration parameter maintenance, and Modbus protocol description document maintenance.

[0057] Among them, Modbus protocol source code maintenance refers to the maintenance of Modbus protocol source code, that is, the maintenance of software code that implements Modbus protocol functions, mainly including correcting errors in the code, updating outdated functions, adding new features, or optimizing existing code to improve performance. For example, if it is found that some functions no longer work as expected during the Modbus communication process, such as failure to read register data, then it is necessary to check and repair the source code responsible for the function and perform Modbus protocol source code maintenance.

[0058] Modbus protocol configuration parameter maintenance refers to the continued maintenance of Modbus protocol configuration parameters, that is, adjusting the configuration parameters related to Modbus communication, in order to ensure the stability and reliability of the communication link. The configuration parameters involved mainly include baud rate, data bit, parity check, stop bit, etc. For example, if the communication between devices is unstable, it may be caused by improper baud rate setting. At this time, it is necessary to adjust the baud rate parameters and perform Modbus protocol configuration parameter maintenance to better adapt to the current communication environment.

[0059] Modbus protocol description document maintenance refers to the maintenance of Modbus protocol description information, that is, updating and maintaining Modbus protocol related description information to ensure the accuracy, completeness and timeliness of its content. For example, with the update of the Modbus protocol version, some information in the old description document may no longer be applicable, so it is necessary to update the description document, perform Modbus protocol description document maintenance, add new function descriptions or correct outdated information.

[0060] In the present embodiment, the Modbus protocol maintenance file is a set of files required for Modbus protocol maintenance, including a Modbus protocol source code file, a Modbus protocol configuration file, and a Modbus protocol description document. Wherein, the Modbus protocol source code file contains the latest Modbus protocol source code, which is used to update the Modbus protocol firmware or software of the device and perform Modbus protocol source code maintenance. The Modbus protocol configuration file stores the latest Modbus protocol configuration parameters, which are used to update the Modbus configuration parameters of the device and perform Modbus protocol configuration parameter maintenance. The Modbus protocol description document includes the latest Modbus protocol description information, which is used to update the Modbus protocol description information of the device and perform Modbus protocol description document maintenance.

[0061] It should also be noted that, in the present embodiment, Modbus protocol data is Modbus protocol related information required to generate a Modbus protocol culture file, typically including register address, register data type, function code, function description, baud rate, check mode, stop bit, device address, data range, data ratio, parameter description, variable noun, variable description, etc. The target Excel file is an Excel file that stores Modbus protocol data. The Modbus protocol maintenance macro is a macro preset in the target Excel file, which is used to generate a Modbus maintenance file based on the Modbus protocol data. The Modbus protocol maintenance event refers to an event that triggers the call of the Modbus protocol maintenance macro to generate a Modbus protocol maintenance file. The target device refers to industrial equipment that requires Modbus protocol maintenance, such as PLC, sensor, actuator, etc.

[0062] In this embodiment, the Modbus protocol data of the target device is stored in a target Excel file, and a Modbus protocol maintenance macro for generating a Modbus maintenance file according to the Modbus protocol data is preset in the target Excel file. Therefore, when it is necessary to perform Modbus protocol maintenance on the target device, it is only necessary to modify the Modbus protocol data of the target device in the target Excel file, and then trigger a Modbus protocol maintenance event based on the Modbus protocol data of the target device in the target Excel file. The Modbus protocol maintenance macro preset in the target Excel file can be called to process the Modbus protocol data of the target device, and the Modbus protocol maintenance file required for performing Modbus protocol maintenance on the target device is automatically generated, and then Modbus protocol maintenance is performed on the target device through the Modbus protocol maintenance file.

[0063] This embodiment realizes the automatic generation of Modbus protocol maintenance files by presetting Modbus protocol maintenance macros in Excel files, eliminating the need for manual writing by maintenance personnel, effectively reducing the workload of maintenance personnel, greatly improving the efficiency of Modbus protocol maintenance, and avoiding maintenance errors that may be caused by manual writing, thereby ensuring the accuracy of Modbus protocol maintenance files and improving the success rate of Modbus protocol maintenance.

[0064] Through the Modbus protocol maintenance method provided in this embodiment, maintenance personnel do not need to have an in-depth understanding of the specific implementation details or programming knowledge of the Modbus protocol. They only need to have basic Excel operation skills to modify the Modbus protocol data in the Excel file and complete most of the Modbus protocol maintenance work, which greatly reduces the technical threshold for Modbus protocol maintenance and the requirements for maintenance personnel's professional knowledge, thereby reducing the company's investment cost in maintenance personnel training.

[0065] In addition, when performing Modbus protocol maintenance, the Modbus protocol maintenance method provided in this embodiment synchronizes the modification of Modbus protocol source code and configuration parameters with the update of description documents, ensuring the consistency between technical documents and actual configurations. Maintenance personnel can refer to the latest description documents at any time to understand the latest status of the equipment, which helps to quickly locate problems when Modbus protocol maintenance is required next time, reduces maintenance difficulties caused by document lags, and prompts the convenience of Modbus protocol maintenance.

[0066] In an embodiment, when facing Modbus protocol maintenance in a large-scale industrial control scenario, the user only needs to store the Modbus protocol data of all devices in a target Excel file in a unified format, and load a pre-written macro code file that can realize the function of generating a Modbus protocol maintenance file according to the Modbus protocol data into the target Excel file, or a professional developer creates a Modbus protocol maintenance macro in the target Excel file, and writes a macro code that realizes the function of generating a Modbus protocol maintenance file according to the Modbus protocol data through a VBA editor to complete the preset of the Modbus protocol maintenance macro, and then in each subsequent Modbus protocol maintenance, the Modbus protocol can be maintained in batches through the Modbus protocol maintenance macro, that is, after the Modbus protocol data of the target devices in this batch that need to be maintained by the Modbus protocol in the target Excel file are modified in sequence, the corresponding Modbus protocol maintenance events are triggered in sequence, and Modbus protocol maintenance files are generated in sequence for maintenance, or after all the Modbus protocol data of the target devices in this batch that need to be maintained by the Modbus protocol in the target Excel file are modified, the Modbus protocol maintenance events for this batch of target devices are uniformly triggered, and Modbus protocol maintenance files are generated in batches and maintenance is completed.

[0067] It should be noted that, in this embodiment, the triggering conditions of the Modbus protocol maintenance event can be set according to actual needs. For example, a control button associated with the Modbus protocol maintenance macro is set in the target Excel file, so that the touching of the control button is used as the triggering condition of the Modbus protocol maintenance event, that is, after detecting the touching of the control button, it is determined that the Modbus protocol maintenance event is triggered. For example, the modification of the Modbus protocol data in the target Excel is used as the triggering condition of the Modbus protocol maintenance event, that is, after detecting that the Modbus protocol data in the target Excel is modified and maintained, it is determined that the Modbus protocol maintenance event is triggered.

[0068] Exemplarily, in a feasible implementation manner, the method further includes step S300:

[0069] Step S300, after detecting that the Modbus protocol data of the target device in the target Excel file has changed, determining a Modbus protocol maintenance event trigger based on the Modbus protocol data of the target device in the target Excel file.

[0070] In this embodiment, the trigger condition of the Modbus protocol maintenance event is the change of Modbus protocol data. It can be triggered immediately after the change, or after the change and confirmation to save the modification. The user can set it according to actual needs.

[0071] Furthermore, in a feasible implementation manner, before step S200, the method further includes step S400:

[0072] Step S400, verifying the Modbus protocol maintenance file, wherein the verification includes integrity verification, consistency verification, security verification and compatibility verification.

[0073] In this embodiment, after the Modbus protocol maintenance file is generated, it is first verified to determine the integrity, consistency, security and compatibility of the Modbus protocol maintenance file, to ensure that the generated maintenance file contains all necessary parts, without missing key components or information, and is consistent with the Modbus protocol data of the corresponding device in the target Excel file, without any deviation or error, and without any security vulnerabilities or risks, to ensure that maintenance according to the Modbus protocol maintenance file will not cause security issues, and that it matches the corresponding device, can run correctly on the corresponding device, and will not conflict with other software or hardware.

[0074] It is not difficult to understand that when the Modbus protocol maintenance file passes the verification, the operation of performing Modbus protocol maintenance on the target device based on the Modbus protocol maintenance file is automatically executed to complete the Modbus protocol maintenance. When the Modbus protocol maintenance file fails to pass the verification, this embodiment will output the verification results and the information detected during the verification process to the maintenance personnel, so that the maintenance personnel can quickly identify the problem and solve the problem. In addition, when the Modbus protocol maintenance files of multiple target devices are verified, it can be set to perform Modbus protocol maintenance normally for those that pass the verification, and only intercept those that fail to pass the verification. After the maintenance personnel check and make corresponding adjustments, the Modbus protocol maintenance file is regenerated and verified again.

[0075] In this embodiment, the Modbus protocol maintenance macro includes a Modbus protocol source code macro, and the Modbus protocol source code file is generated as follows:

[0076] Calling a Modbus protocol source code macro preset in a target Excel file, performing code generation on the Modbus protocol data, obtaining a Modbus protocol source code, and generating a Modbus protocol source code file according to the Modbus protocol source code;

[0077] Wherein, the step of generating a Modbus protocol source code file according to the Modbus protocol source code comprises steps A10 to A20:

[0078] Step A10, writing the Modbus protocol source code into a first form preset in the target Excel file, and after detecting a source code export instruction based on the first form, exporting the Modbus protocol source code in the first form into a Modbus protocol source code file according to the source code export instruction;

[0079] Step A20, alternatively, importing the Modbus protocol source code into a preset source code file to obtain a Modbus protocol source code file.

[0080] It should be noted that the Modbus protocol source code macro is a macro specifically used to generate a Modbus protocol source code file. When the macro is called, code can be generated for the Modbus protocol data to obtain the Modbus protocol source code, thereby generating a Modbus protocol source code file based on the Modbus protocol source code.

[0081] After the Modbus protocol source code is generated, it can be written into the target Excel file first, and then exported as a Modbus protocol source code file after verification. Alternatively, the created source code file can be directly imported to obtain the Modbus protocol source code file.

[0082] If it is written into the target Excel file first, and then exported as a Modbus protocol source code file after detection and confirmation, it can be written into the first form in the target Excel file. The first form can be a pre-created form specifically used to store and display the Modbus protocol source code, or it can be a form temporarily created when generating the Modbus protocol source code, or a form specified by the user.

[0083] This embodiment writes the Modbus protocol source code into the first form, so that the maintenance personnel can check it at the first time. After checking and confirming that it is correct, the maintenance personnel inputs the source code export instruction, so as to export the Modbus protocol source code in the first form into a Modbus protocol source code file according to the source code export instruction.

[0084] It is not difficult to understand that when the first form stores multiple copies of Modbus protocol source codes of different devices, you can choose to export all of them, or you can choose to export only one or more of them.

[0085] In this embodiment, the Modbus protocol maintenance macro includes a Modbus protocol configuration macro, and the Modbus protocol configuration file is generated as follows:

[0086] Calling the Modbus protocol configuration macro preset in the target Excel file, performing configuration analysis on the Modbus protocol data, obtaining Modbus protocol configuration parameters, and generating a Modbus protocol configuration file according to the Modbus protocol configuration parameters;

[0087] Among them, the step of generating a Modbus protocol configuration file according to the Modbus protocol configuration parameters includes steps B10 to B20:

[0088] Step B10, writing the Modbus protocol configuration parameters into a second form preset in the target Excel file, and after detecting a configuration parameter export instruction based on the second form, exporting the Modbus protocol configuration parameters in the second form as a Modbus protocol configuration file according to the configuration parameter export instruction;

[0089] Step B20, alternatively, importing the Modbus protocol configuration parameters into a preset configuration file to obtain a Modbus protocol configuration file.

[0090] It should be noted that the Modbus protocol configuration macro is a macro specifically used to generate a Modbus protocol configuration file. When the macro is called, it can perform configuration parsing on the Modbus protocol data to obtain the Modbus protocol configuration parameters, thereby generating a Modbus protocol configuration file based on the Modbus protocol configuration parameters.

[0091] After the Modbus protocol configuration parameters are generated, they can be written into the target Excel file first, and then exported as a Modbus protocol configuration file after being tested and confirmed to be correct. Alternatively, the created configuration file can be directly imported to obtain the Modbus protocol configuration file.

[0092] If it is written into the target Excel file first, and then exported as a Modbus protocol configuration file after detection and confirmation, it can be written into the second form in the target Excel file. The second form can be a pre-created form specifically used to store and display Modbus protocol configuration parameters, or it can be a form temporarily created when generating Modbus protocol configuration parameters, or a form specified by the user.

[0093] This embodiment writes the Modbus protocol configuration parameters into the second form, so that the maintenance personnel can check them at the first time. After checking and confirming that they are correct, the maintenance personnel inputs the configuration parameter export instruction, so that the Modbus protocol configuration parameters in the second form are exported as a Modbus protocol configuration file according to the configuration parameter export instruction.

[0094] It is not difficult to understand that when the second form stores multiple copies of Modbus protocol configuration parameters of different devices, you can choose to export all of them, or you can choose to export only one or more of them.

[0095] In this embodiment, the Modbus protocol maintenance macro includes a Modbus protocol description macro, and the Modbus protocol description document is generated as follows:

[0096] Calling a Modbus protocol description macro preset in a target Excel file, performing description analysis on the Modbus protocol data, obtaining Modbus protocol description information, and generating a Modbus protocol description document according to the Modbus protocol description information;

[0097] The step of generating a Modbus protocol description document according to the Modbus protocol description information includes steps C10 to C20:

[0098] Step C10, writing the Modbus protocol description information into a third form preset in the target Excel file, and after detecting a description information export instruction based on the third form, exporting the Modbus protocol description information in the third form into a Modbus protocol description document according to the description information export instruction;

[0099] Step C10, alternatively, importing the Modbus protocol description information into a preset description document to obtain a Modbus protocol description document.

[0100] It should be noted that the Modbus protocol description macro is a macro specifically used to generate a Modbus protocol description document. When the macro is called, it can parse the Modbus protocol data to obtain the Modbus protocol description information, and then generate a Modbus protocol description document based on the Modbus protocol description information.

[0101] After the Modbus protocol description information is generated, it can be written into the target Excel file first, and then exported as a Modbus protocol description document after verification. Alternatively, the created description document can be directly imported to obtain the Modbus protocol description document.

[0102] If it is written into the target Excel file first, and then exported as a Modbus protocol description document after detection and confirmation, it can be written into a third form in the target Excel file.
