[0015] The controller address operation method provided in this application can be applied to Figure 1 application environment. Figure 1 1 is an application environment diagram of a controller address operation method in an embodiment. It includes a host computer 110, a human-machine interface 120 and a controller 130. The host computer 110 can be, but is not limited to, various personal computers, laptops, smart phones, tablet computers and portable wearable devices. The human-machine interface (HMI) 120 is a medium for interaction and information exchange between the system and the user. The controller 130 refers to an industrial controller, which can be a PLC (Programmable Logic Controller). PLC is an operating system designed specifically for use in an industrial environment. The host computer 110 is used to generate scripts, and the human-machine interface 120 is used to receive and execute scripts to control the controller 130.

[0016] In one embodiment, Figure 2 FIG. 1 is a flow chart of a controller address operation method in an embodiment, which is described by taking the method applied to a human-machine interface as an example, and includes the following steps: Step 202, obtaining a script sent by the host computer; the script includes an interface to be operated for operating the controller and an address of the controller to be operated.

[0017] The address of the controller to be operated is an address in the controller, and a certain operation needs to be performed on the address of the controller to be operated.

[0018] There is a mapping relationship between the interface to be operated in the script and the application interface. Calling a certain interface in the script will be mapped to the corresponding application interface. The application interface encapsulates the relevant operations of the controller address. If the script contains the interface to be operated for operating the controller, the application interface can be called to control the controller. For example, the application interface includes functions such as reading data, writing data, and calculating data.

[0019] Specifically, in the HMI application, the address-related operations on the controller are encapsulated into an application programming interface (API) that can be called by the script. The user can write a script on the host computer according to the provided application programming interface, and the host computer sends the script to the HMI after completion. The HMI obtains the script sent by the host computer, which includes the address of the controller to be operated and the interface to be operated for operating the controller.

[0020] Step 204, calling the application program interface corresponding to the interface to be operated through the script, and completing the corresponding operation on the address of the controller to be operated.

[0021] Specifically, the script calls the application program interface corresponding to the interface to be operated to complete the corresponding operation on the target controller address to be operated. For example, if the read interface is called through the script, the HMI reads the corresponding value from the controller address to be operated of the controller. Alternatively, the script also includes the value of the controller address to be operated, and the write interface is called through the script, then the HMI writes the corresponding value to the controller address to be operated of the controller.

[0022] In this embodiment, by obtaining the address of the controller to be operated and the interface to be operated for operating the controller sent by the host computer, the application program interface corresponding to the interface to be operated is called through the script to complete the corresponding operation on the address of the controller to be operated. That is, the relevant address of the controller is operated through the script, and the control logic can be updated without shutting down the controller and changing the controller code, thereby reducing the impact caused by disassembly and shutdown of the controller and making the update more convenient. In addition, the control logic of the script is simple, and it is easier to complete the operation of the controller.

[0023] In one embodiment, the calling of the application program interface corresponding to the interface to be operated by the script to complete the corresponding operation on the address of the controller to be operated includes: Parsing the script, executing the functional logic in the script, and obtaining an execution result; An application program interface corresponding to the interface to be operated is called, and a corresponding operation on the address of the controller to be operated is completed based on the execution result.

[0024] The functional logic in the script depends on the type of script used, such as including but not limited to logical AND, OR, NOT, XOR, and EQUAL.

[0025] Specifically, the HMI parses the script, executes the functional logic in the script, and obtains the execution result. The HMI calls the application program interface corresponding to the interface to be operated, and writes the execution result into the operation of the address of the controller to be operated.

[0026] In this embodiment, the execution result is obtained by parsing the script, and the corresponding operation on the address of the controller to be operated is completed based on the execution result. The logic of part of the controller can be completed in the script. Due to the poor performance of the controller, the complex logical operations in the controller are put on the HMI to complete, and then the calculated results are written to the HMI through the application program interface. This can reduce the computing pressure of the controller and improve the control performance.

[0027] In one embodiment, parsing a script, executing the functional logic in the script, and obtaining an execution result include: parsing the script through a script interface of an application program, and executing the functional logic in the script.

[0028] Specifically, a supported script interface is built into the HMI application program. The HMI parses the script through the script interface of the application program and can execute the functional logic in the script.

[0029] In this embodiment, a script interface is built into the application, and the script is parsed through the script interface of the application to execute the functional logic in the script. The script can be used to quickly implement logical adjustment, modification and extension of the industrial controller, thereby reducing the impact of controller disassembly and shutdown.

[0030] In one embodiment, the controller address operation method further includes: when receiving data sent by the controller, calling a display interface of an application program through a script to display the data.

[0031] Specifically, when data sent by the controller is received, the display interface of the application is called through the script, and the data is displayed.

[0032] In this embodiment, when data sent by the controller is received, the display interface of the application is called through a script to display the data, thereby completing two-way communication of data and monitoring the controller simply and quickly.

[0033] In one embodiment, the script is a Lua script.

[0034] Specifically, the script syntax and operation use the open source architecture Lua. In the HMI, the data interaction between the script and the application uses the heap structure in Lua. The script and the application realize data interaction through a common heap. The application interface is encapsulated on the basis of data interaction.

[0035] In this embodiment, the Lua script file can be modified dynamically. This feature can complete the logic adjustment, modification, and extension of the controller without shutting down the controller, reducing the impact of controller disassembly and shutdown. In addition, Lua scripts can be flexibly embedded in applications to provide flexible expansion and customization functions for applications. They can be compiled and run on almost all operating systems and platforms, and have strong versatility. Compared with other scripting languages, they do not require pre-defined characters, are easy to use, and are suitable for industrial scenarios.

[0036] In one embodiment, the script syntax and operation use the open source architecture Lua. In the HMI, the data interaction between the script and the application uses the heap structure in Lua. The script and the application use a common heap to achieve data interaction. The API interface is encapsulated on the basis of data interaction. There is a mapping table between the script and the application. Calling a certain interface in the script will be mapped to the corresponding application interface.

[0037] The HMI application program has a built-in script interface. The user writes the code logic of the script in the host computer and sends the script file to the HMI after editing. The script is executed through the script interface of the application program in the HMI. The script calls the corresponding application program interface to execute the operation logic and complete the operation of the external controller.

[0038] Therefore, the script includes the address of the controller to be operated and the interface to be operated for operating the controller, and may also include the target value of the controller address and the functional logic configured in the script. The application program interface encapsulates the relevant operations on the controller address, such as read operations, write operations, calculation operations, etc.

[0039] The main function is to encapsulate the address-related operations on the industrial controller into a Lua callable API in the application. The user writes a script on the host computer according to the provided API, and the host computer sends the script to the HMI after completion. The user can call the API of the operation control-related address defined in the application through the script on the HMI to complete the operation of the controller address value. In addition, part of the controller logic can be completed in the Lua script. Using this solution, the complex logical operations in the controller can be completed on the HMI (HMI performance is better than the controller), and then the calculation results can be written back to the controller through the Lua interface through the application, reducing the calculation pressure of the controller and improving the control performance.

[0040] In this embodiment, script programming is used to operate the values ​​of the relevant addresses of the industrial controller, and new control logic can be added to the logic of the original controller code without changing it. A part of the complex logic and operation can be implemented in the script, and the function of the original controller can be flexibly expanded. In addition, the Lua script file can be dynamically modified. This feature can complete the logic adjustment, modification, and extension of the controller without shutting down the controller, reducing the impact of controller disassembly and shutdown.

[0041] In one embodiment, a controller address operation method is applied to a human-machine interface, comprising: Step (a1), obtaining a Lua script sent by a host computer; the Lua script includes an address of a controller to be operated and an interface to be operated for operating the controller.

[0042] Step (a2), parse the Lua script through the script interface of the application, execute the functional logic in the Lua script, and obtain the execution result.

[0043] Step (a3), calling the application program interface corresponding to the interface to be operated, and completing the corresponding operation on the controller address to be operated based on the execution result.

[0044] Step (a4), when the data sent by the controller is received, the display interface of the application is called through the Lua script to display the data.

[0045] In this embodiment, the Lua script can complete part of the controller's logic, and the complex logic operations in the controller can be put on the HMI to complete (the HMI performance is better than the controller), and then the calculation results are written back to the controller through the Lua interface through the application, reducing the controller's computing pressure and improving control performance. On the other hand, the Lua script file can be modified dynamically. This feature can complete the controller's logic adjustment, modification, and extension without shutting down the controller, reducing the impact of controller disassembly and shutdown. It should be understood that although the above Figure 2 The steps in the flowchart are shown in sequence as indicated by arrows, and the steps in steps (a1) to (a4) are shown in sequence as indicated by numbers, but these steps are not necessarily performed in the order indicated by arrows or numbers.
