[0050] To make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. However, it will be appreciated by those skilled in the art that in the embodiments of the present invention, many technical details are proposed in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can be implemented. The division of the following embodiments is for the convenience of description, and should not constitute any limitation on the specific implementation of the present invention. The various embodiments can be combined and referenced with each other without contradiction.

[0051] Reference Figure 1 , shows a flowchart of the steps of a program management method for a programmable logic controller provided by an embodiment of the present invention, which is applied to a program management system, wherein the program management system is communicatively connected with a programmable logic controller, and the method may include:

[0052] Step 101: Send a program backup request to a programmable logic controller to be backed up, and determine the current program data of the programmable logic controller.

[0053] In the embodiment of the present application, in order to solve the problem that when the program and related data of the programmable logic controller are accidentally lost or program quality problems occur, on-site staff can only manually perform data transmission and backup through traditional backup methods such as a single laptop, CF card, USB flash drive, etc., and the data backup is not timely and efficient, this embodiment uses an integrated program management system to perform online real-time backup of the program data stored in the programmable logic controller, ensuring that in unexpected situations such as hardware failure or error, the data is backed up in a timely and effective manner to avoid program data loss or damage. Even if the data is lost or damaged, the PLC function can be quickly restored to ensure the continuity of the production line, and the program data of the PLC is compared and analyzed, and the backup data and the current data are compared to achieve more effective troubleshooting and repair. Through the automatic and efficient management of the online real-time backup and comparative analysis of the PLC, the integrity and security of the data are ensured, and the management effect of the program data of the programmable logic controller is improved.

[0054] Reference Figure 6 , showing a scenario diagram of the program management method for a programmable logic controller provided by an embodiment of the invention, the program management system is connected to the programmable logic controller in communication, specifically, the PLC device is connected to the program management system of the server IOT platform through the RJ45 interface and the TCP / IP protocol, the BoTu software and the PLC device are in the same network segment and are connected to the program management system of the IOT platform, the engineer's computer and the server install and register the plug-in, the engineer's computer runs the plug-in, and logs in with the program management system account, the engineer's computer and the server of the program management system establish a communication trust mechanism, the user end can trigger the data backup operation, thereby realizing the integrated program management system to perform online real-time backup of the program data stored in the programmable logic controller, and realizing automatic and efficient management of online real-time backup and comparative analysis of the PLC.

[0055] Specifically, the program management system determines the target programmable logic controller to be backed up through a preset interface. In response to a user-triggered backup operation or a timed-triggered backup operation, the program management system sends a program backup request to the target programmable logic controller and determines the current program data of the target programmable logic controller. In response to a backup operation manually triggered by the user or a timed-triggered backup operation by the system, the program management system sends a program backup request to the target PLC device. The program backup request triggers the PLC device to prepare for a program upload operation and determines the current program data of the PLC device.

[0056] It should be noted that, in this embodiment, the preset interface can be a Botu software interface, which is used for the program management system to interact with the Botu software. The Botu software interface is the application programming interface of the Botu software, allowing developers to interact with the Botu software through programming. The Botu software is an integrated automation engineering software platform. The program management system can determine the target programmable logic controller to be backed up by the program management system through the Botu software interface.

[0057] It should be noted that the current program data of the PLC (Programmable Logic Controller) device includes the currently running program code and related configuration data stored in the PLC device. The program code is the logic program running in the PLC device, and the program code defines how the PLC device responds to input signals, performs logical operations, controls output devices, etc.; the configuration data of the PLC device includes input / output (I / O) mapping, module configuration, communication settings, timer and counter settings, etc. The configuration data defines the hardware configuration and operating parameters of the PLC device, and can also include variables and parameters used in the PLC device, specifically including global variables, local variables, constants, system parameters, etc., which are used to store and transfer data and support the logical operations and control of the program. This embodiment does not specifically limit this.

[0058] Step 102, uploading the current program data to the program management system, and performing a repeatability check on the current program data and the program data in the preset program library.

[0059] In an embodiment of the present application, the current program data is uploaded to the program management system through a preset interface, the current program data is used to traverse the program data of the preset program library, it is determined whether the current program data and the program data of the preset program library are repeated, and a repeatability verification result of the current program data is obtained.

[0060] Specifically, after the Botu software establishes communication with the PLC device, the current program data of the PLC device is uploaded to the program management system through the preset interface of the Botu software to ensure that the program management system can obtain the latest PLC program data. The program management system uses the current program data to traverse the program data in the preset program library, wherein the preset program library (Program Library) is a database system that centrally stores and manages the program data of the PLC device, and is used to store the backup program data of the PLC device to ensure that the program data can be quickly restored when needed to prevent data loss. In this embodiment, it is determined whether the current program data is repeated with the program data in the preset program library, and by comparing the program name, version number and code, it is quickly determined whether the program is repeated, and the repeatability verification result of the current program data is obtained.

[0061] Step 103, when the repeatability check passes, the current program data is backed up to the preset program library.

[0062] Step 104 , monitoring the current program data of the programmable logic controller, comparing the current program data with the backup program data in the preset program library, and obtaining a program data comparison result.

[0063] In an embodiment of the present application, the program management system monitors the current program data of the programmable logic controller in real time to ensure that the program management system can obtain the latest program data of the PLC device in a timely manner. If it is monitored that the current program data of the PLC device has changed, the program management system determines a program comparison mode, and the program comparison mode includes an online comparison mode or an offline comparison mode. The program management system uses the online comparison mode or the offline comparison mode to compare the current program data with the backup program data in the preset program library to obtain a program data comparison result.

[0064] The program management method of a programmable logic controller provided by an embodiment of the present invention determines the current program data of the programmable logic controller by sending a program backup request to the programmable logic controller to be backed up, uploads the current program data to the program management system, performs a repeatability check on the current program data and the program data of the preset program library, and backs up the current program data to the preset program library when the repeatability check passes, monitors the current program data of the programmable logic controller, compares the current program data with the backup program data in the preset program library, and obtains the program data comparison result. The integrated program management system of the embodiment of the present invention performs online real-time backup of the program data stored in the programmable logic controller, ensures that in unexpected situations such as hardware failure or error, the data is backed up in a timely and effective manner to avoid program data loss or damage, and even if the data is lost or damaged, the PLC function can be quickly restored to ensure the continuity of the production line, and the program data of the PLC is compared and analyzed, and the backup data and the current data are compared to achieve more effective troubleshooting and repair, and the integrity and security of the data are ensured through automatic and efficient management of online real-time backup and comparative analysis of the PLC, and the management effect of the program data of the programmable logic controller is improved.

[0065] Further, see Figure 2 , showing Figure 1 A flowchart of step 101 in a program management method for a programmable logic controller is provided. The method is substantially the same as the program management method for a programmable logic controller provided in the first embodiment of the present invention. Step 101 may include:

[0066] Step 201: determine the target programmable logic controller to be backed up by the program management system through a preset interface.

[0067] Step 202: In response to a user-triggered backup operation or a timer-triggered backup operation, a program backup request is sent to a target programmable logic controller to determine current program data of the target programmable logic controller.

[0068] It should be noted that in the above steps, the program management system determines the target programmable logic controller (PLC) to be backed up through a preset interface (such as the Botu software API) to ensure that the program management system can accurately identify the PLC devices that need to be backed up. In order to improve the flexibility of the system, it can support batch selection of multiple PLC devices for backup. In addition, the device management function can also be integrated to monitor the status of the PLC device in real time to ensure the smooth progress of the backup operation.

[0069] Specifically, in response to a backup operation manually triggered by a user or a backup operation timed by the system, the program management system sends a program backup request to the target PLC device. The program backup request triggers the PLC device to prepare for a program upload operation and determines the current program data of the PLC device. In this embodiment, in order to improve the degree of automation of backup, a variety of trigger mechanisms can be set, such as scheduled backup, event-triggered backup (such as device restart, program update, etc.) and user-manually triggered backup. A notification function can also be integrated to send a notification to the user after the backup operation is completed to ensure that the user is aware of the backup status in a timely manner.

[0070] The embodiment of the present application realizes an automated backup process by triggering a backup and sending a program backup request to the target programmable logic controller, thereby reducing manual backup operations, improving backup efficiency, and ensuring timely backup of the program. The automated backup process reduces human intervention, reduces the probability of human errors, and improves the reliability of program data management.

[0071] Further, see Figure 3 , showing Figure 1 A flowchart of step 102 in a program management method for a programmable logic controller is provided. The method is substantially the same as the program management method for a programmable logic controller provided in the first embodiment of the present invention. Step 102 may include:

[0072] Step 301, uploading current program data to the program management system through a preset interface.

[0073] Step 302, using the current program data to traverse the program data of the preset program library, determine whether the current program data and the program data of the preset program library are repeated, and obtain a repeatability verification result of the current program data.

[0074] It should be noted that in the above steps of the embodiment of the present application, after the Botu software establishes communication with the PLC device, the current program data of the PLC device is uploaded to the program management system through the preset interface of the Botu software to ensure that the program management system can obtain the latest PLC program data. In order to improve the efficiency of uploading, incremental upload technology can be used to upload only the changed part of the program to reduce the amount of data transmission. The breakpoint resume function can also be integrated to ensure that the upload operation can be resumed when the network is interrupted to avoid data loss. This embodiment is not specifically limited by comparison.

[0075] Specifically, the current program data is used to traverse the program data in the preset program library to determine whether the current program data and the program data in the preset program library are repeated, and the repeatability verification result of the current program data is obtained. The program management system uses the current program data to traverse the program data in the preset program library to determine whether the current program data and the program data in the preset program library are repeated. By comparing the program name, version number and code, it is quickly determined whether the program is repeated to obtain the repeatability verification result of the current program data. This embodiment can use a variety of verification algorithms for verification, which are not specifically limited here. The version management function can also be integrated to record the version information of each backup for easy traceability and management. If the current program data and the program data in the preset program library are not repeated, the program management system uploads the current program data to the program library for backup to ensure that the latest program data can be backed up in time to prevent data loss. If the current program data and the program data in the preset program library are repeated, the backup operation is ignored to avoid repeated backup and reduce system resource consumption.

[0076] The embodiment of the present application utilizes the current program data to traverse the program data of the preset program library to determine whether the current program data and the program data of the preset program library are duplicated, ensuring that the latest program data can be backed up in time to prevent data loss, and ignoring the backup operation when the current program data and the program data of the preset program library are duplicated to avoid duplicate backup.

[0077] Further, see Figure 4 , showing Figure 1 A flowchart of step 104 in a program management method for a programmable logic controller is provided. The method is substantially the same as the program management method for a programmable logic controller provided in the first embodiment of the present invention. Step 104 may include:

[0078] Step 401, monitoring current program data of the programmable logic controller.

[0079] Step 402: If it is detected that the current program data has changed, determine the program comparison mode; wherein the program comparison mode includes an online comparison mode or an offline comparison mode.

[0080] Step 403 : compare the current program data with the backup program data in the preset program library in an online comparison mode or an offline comparison mode to obtain a program data comparison result.

[0081] In the embodiment of the present application, the program management system monitors the current program data of the programmable logic controller (PLC) in real time to ensure that the program management system can obtain the latest program data of the PLC device in a timely manner. In order to improve the accuracy of monitoring, a variety of monitoring technologies can be used, such as periodic monitoring, event-triggered monitoring, etc., and the device status monitoring function can be integrated to display the status of the PLC device in real time. If the current program data of the PLC device is monitored to change, the program management system determines the program comparison mode, which includes an online comparison mode or an offline comparison mode. The online comparison mode is suitable for situations where the PLC device program needs to be compared in real time, and the offline comparison mode is suitable for situations where different versions of the program need to be compared.

[0082] Specifically, the program management system uses an online comparison mode or an offline comparison mode to compare the current program data with the backup program data in the preset program library to obtain a program data comparison result. According to the determined program comparison mode, the program management system uses an online comparison mode or an offline comparison mode to compare the current program data with the backup program data in the preset program library. By comparing the program name, version number and code, it can accurately determine whether the programs are consistent and obtain a program data comparison result.

[0083] The embodiment of the present application uses an online comparison mode or an offline comparison mode to compare the current program data with the backup program data in the preset program library, which can timely and accurately determine whether the programs are consistent, so as to compare the backup data and the current data to achieve more effective troubleshooting and repair.

[0084] Specifically, in some embodiments, step 403, using an online comparison mode or an offline comparison mode to compare the current program data with the backup program data in the preset program library, and obtaining the program data comparison result may specifically include:

[0085] First, an online comparison request is sent to the programmable logic controller, and the changed current program data is uploaded to the program management system;

[0086] Secondly, obtaining the backup program data in the preset program library;

[0087] Secondly, the changed current program data is compared with the backup program data in the preset program library to obtain a program data comparison result.

[0088] It should be noted that in the above steps, the program management system sends an online comparison request to the programmable logic controller and uploads the changed current program data to the program management system. Specifically, the program management system sends an online comparison request to the programmable logic controller (PLC), triggering the PLC device to upload the changed current program data to the program management system, ensuring that the program management system can obtain the latest PLC program data. At the same time, the program management system obtains backup program data from the preset program library to ensure that the program management system can obtain the backup program data for comparison. The program management system compares the changed current program data with the backup program data in the preset program library to determine whether the programs are consistent and obtain the program data comparison result.

[0089] In some embodiments, an online comparison mode is used to compare the current program data with the backup program data in the preset program library. Specifically, communication is established with the PLC device through the Botu API, and the execution program is uploaded to the engineer's computer so that the engineer can perform comparison operations and obtain the Botu comparison results. If the Botu comparison results cannot be obtained automatically, consider having the engineer input the Botu comparison results and complete it manually. The system obtains the comparison results. The engineer performs program comparison operations in the Botu software and obtains the Botu comparison results. If the Botu software cannot automatically obtain the comparison results, the engineer can manually input the comparison results. The system obtains and records the comparison results. By integrating the automated script of the Botu software, the comparison operation is automatically performed and the comparison results are obtained.

[0090] The embodiment of the present application integrates the automation script of the BoTu software to automatically perform online comparison operations on program data and obtain comparison results. Through automatic and efficient management of PLC online real-time backup and comparative analysis, the integrity and security of the data are ensured, thereby improving the management effect of programmable logic controller program data.

[0091] Specifically, in some embodiments, step 403, using an online comparison mode or an offline comparison mode to compare the current program data with the backup program data in the preset program library, and obtaining the program data comparison result may specifically include:

[0092] First, an offline comparison request is sent to a programmable logic controller, and the backup program data in the preset program library is sent;

[0093] Secondly, the backup program data is compared with the current program data of the programmable logic controller to obtain a program data comparison result.

[0094] It should be noted that in the above steps, the program management system sends an offline comparison request to the programmable logic controller (PLC) and sends the backup program data in the preset program library to ensure that the PLC device can obtain the backup program data for comparison. The PLC device compares the sent backup program data with the current program data to determine whether the programs are consistent and obtain the program data comparison results.

[0095] For example, the backup program data in the preset program library is selected and sent to the engineer's computer, and the Botu software is automatically opened. The engineer selects the backup program data in the preset program library. The program management system sends the program to be compared to the engineer's computer and automatically opens the Botu software to ensure that the engineer can quickly start the program comparison operation. The engineer performs the comparison operation and obtains the Botu comparison result. If the Botu comparison result cannot be obtained automatically, consider having the engineer input the Botu comparison result and complete it manually. The system obtains the comparison result. The engineer performs the program comparison operation in the Botu software and obtains the Botu comparison result. If the Botu software cannot automatically obtain the comparison result, the engineer can manually input the comparison result. The system obtains the comparison result and records it. In order to improve the degree of automation of the comparison, the Botu software's automation script can be integrated to automatically perform the comparison operation and obtain the comparison result.

[0096] The embodiment of the present application integrates the automated script of the BoTu software to automatically perform offline comparison operations on program data and obtain comparison results. By comparing and analyzing PLC backup data, data consistency is ensured and the management effect of programmable logic controller program data is improved.

[0097] Reference Figure 5 , shows a flowchart of the steps of another programmable logic controller program management method provided by an embodiment of the present invention, which method is basically the same as the programmable logic controller program management method provided by the first embodiment of the present invention, except that the method may further include:

[0098] Step 101: Send a program backup request to a programmable logic controller to be backed up, and determine the current program data of the programmable logic controller.

[0099] Step 102, uploading the current program data to the program management system, and performing a repeatability check on the current program data and the program data in the preset program library.

[0100] Step 103, when the repeatability check passes, backing up the current program data to a preset program library.

[0101] Step 104 , monitoring the current program data of the programmable logic controller, comparing the current program data with the backup program data in the preset program library, and obtaining a program data comparison result.

[0102] The above steps 101 to 104 are described in the foregoing description and will not be repeated here.

[0103] Step 105, displaying the program data comparison result to the Botu software, and the program data comparison result is used by the user to troubleshoot the programmable logic controller.

[0104] In an embodiment of the present application, the program data comparison results are displayed to the BoTu software, and the program data comparison results are used by users to troubleshoot programmable logic controllers. The program management system displays the program data comparison results to the BoTu software to ensure that users can intuitively view the comparison results and troubleshoot the programmable logic controller based on the comparison results. In order to improve the user experience, visualization tools can be integrated to display the comparison results in a graphical manner.
