Detailed Description
As shown in fig. 1, the visual configuration programming system according to the embodiment of the present invention includes a configuration interaction module 1, a script generation module 2, an operation debugging module 3, and an encryption module 4. The following description will be made separately.
The configuration interaction module 1 is used for providing a visual interface for a user to perform configuration programming and providing a code input interface for the user to input a script program code.
It should be noted that the visual interface provided by the configuration interaction module 1 includes a plurality of logic modules, and a user can perform configuration programming by setting the order of the plurality of logic modules and setting the input/output variables of each logic module. The configuration interaction module also provides a code input interface, and a user can directly input script codes in the code input interface for programming. After the user completes programming by means of configuration programming or completes programming by means of code input, the configuration interaction module 1 identifies the programming logic of the user.
And the script generation module 2 is used for converting the programming logic set by the user into a script program code which can be executed by the controller. The script generation module 2 can analyze the logic module sequence, the module type, the module input and output relationship and the period variable storage relationship set by the user and uniformly generate script program codes.
And the running debugging module 3 is used for running and debugging the script program code generated by the script generating module 2.
The encryption module 4 is configured to encrypt the script program code that is generated by the script generation module 2 and that is executable by the controller. In order to prevent the programming logic set by the user from being maliciously tampered, the user can choose to encrypt the script program code generated by the script generation module 2 by using the encryption module.
In the embodiment of the present invention, the script generating module 2 includes a variable storage managing unit 21, a thread managing unit 22, a main running program managing unit 23, and a code encapsulating unit 24.
The variable storage management unit 21 is configured to perform unified management on various variables generated in the program logic operation process. These variables include global storable variables, global non-storable variables, and local variables. The variable storage management unit 21 may store the variable data by using a memory or a persistence technology.
The thread management unit 22 establishes an independent thread for each scene in the operation process of the programming logic and manages each thread. The thread management unit 22 is mainly responsible for managing thread delays, managing the life cycles of threads, and managing thread locks in coordination with each other among threads.
And the main running program management unit 23 is configured to load a variable module, a custom module, and a third library module required by the running of each thread.
The code packaging unit 24 is used for automatically packaging the script code input by the user into a self-defined logic module. It should be noted that the script code input by the user is also a programming logic, and the code encapsulating unit 24 encapsulates the script code input by the user into a self-defined logic module, and the self-defined logic module can be displayed in a graphical form and graphically edited together with the self-contained logic module in the configuration software.
As shown in fig. 2, the programming process using the visual configuration programming system is as follows:
first, a user newly builds an engineering project. In the established engineering project, a user can establish a plurality of scenes, and the system generates one scene by default. Each independent operation logic unit is in an independent scene; the user can select different programming modes to program the logic, can select a mode of directly writing codes, and can also select a mode of programming through graphical configuration.
If the user programs by directly writing the codes, the system automatically packages the codes written by the user when the user selects to store after writing the complete codes, identifies the programming logic of the user and forms a self-defined logic module.
If the user selects the configuration programming mode, the user can connect the logic modules and the process in a graphical configuration mode, and the system can analyze the programming logic of the user according to the configuration graph connected by the user and disassemble the corresponding logic operation module.
Then, converting the programming logic set by the user into a script program code operated by the controller, wherein the specific process comprises the following steps: the variable storage management unit 21 establishes a stack, and performs unified management on various variables generated in the programming logic operation process; the thread management unit 22 establishes an independent thread for each scene in the programming logic operation process and manages each thread; the main running program management unit 23 loads a variable module, a custom module and a third library module required for running of each thread.
And then, operating and debugging the generated script program code, wherein the visual configuration programming system can independently operate at the PC end, but can perform real-time data interaction with the field controller through an independent interface.
And finally, directly issuing the generated script program code to a field controller, and independently operating by the field controller.
In summary, in the visual configuration programming method and system of the present invention, the programming logic input by the graphical configuration programming method or the programming logic input directly through the script code is converted into the script program code executable by the controller, because the script language is a general language, most programmers can quickly grasp the script program code, and the universality of the configuration programming is improved; in addition, the script voice can be directly issued to the controller to execute the logic program, so that the compiling time is saved, and the online debugging efficiency can be improved.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
