It should be noted that, in the embodiments of the present application, features in the embodiments and the examples may be arbitrarily combined with each other without conflict.

Fig. 1 is a flowchart of a method for managing logic blocks in an industrial controller according to an embodiment of the present disclosure.

The method shown in fig. 1, comprising:

step 101, obtaining a custom logic block of which the internal logic in the industrial controller meets a preset secrecy judgment condition;

in an exemplary embodiment, part of the control logic in the industrial control is provided for others to use as a whole, and part of the internal logic cannot be exposed due to confidentiality, so that design consideration can be given to the confidentiality, and a judgment condition for confidentiality can be set for the internal logic. And analyzing and determining the logic for keeping the internal logic secret by knowing a preset secret judgment condition, and taking the logic as a self-defined logic block.

102, determining at least one target logic block for realizing the function of the self-defined logic block from prestored logic blocks;

in the related art, the custom logic block is realized through a programming language, and then a dynamic link library is directly generated and called by a controller. The scheme has higher requirements on logic designers, requires the logic designers to have programming capability and has higher development difficulty. Different from the related technology, the method determines the composition of the function of the self-defining module, matches the function with the function of the existing logic block, and determines which logic blocks can be combined to realize the function of the self-defining module, namely determines at least one target logic block for realizing the function of the self-defining logic block, reduces the development difficulty of the self-defining logic block by means of the function of the existing logic block, and fully utilizes the existing logic block.

And 103, carrying out configuration operation on at least one target logic block in a preset logic page to obtain a custom logic block.

In an exemplary embodiment, the deployment of the functions of the target logic block is completed by means of a graphical management mechanism in the logic page, the control of input operation and output operation is realized, the function of the custom logic block is realized, and the requirements of a logic designer are reduced.

According to the method provided by the embodiment of the application, the user-defined logic block of which the internal logic accords with the preset secrecy judgment condition in the industrial controller is obtained, at least one target logic block for realizing the function of the user-defined logic block is determined from the pre-stored logic blocks, and the configuration operation is carried out on the at least one target logic block in the preset logic page to obtain the user-defined logic block, so that the packaging of the user-defined logic block is completed by utilizing a graphical configuration mode, the development difficulty of the user-defined logic block is reduced, and the development efficiency is improved.

The method provided by the embodiments of the present application is explained as follows:

in an exemplary embodiment, after the configuring operation is performed on at least one logic block in the preset logic page to obtain the custom logic block, the method further includes:

carrying out configuration operation by utilizing the user-defined logic block and the logic block acquired in advance to obtain a complete target file of the internal logic of the industrial controller;

executing the complete target file in the industrial controller.

In the related art, a source file of a packaged logical block is directly in an object file of a compiled logical page, and when a logical graph includes a plurality of repeated self-defined functional blocks, the object file of the logical page becomes very large, which affects execution efficiency. The difference with the related technology is that the target file is generated by the self-defined function block and downloaded to the controller to be used as a callable library, only the identification of the self-defined function block is stored in the common logic diagram to call the target file of the self-defined logic block from the library, so that the problem of expansion of the target file of the common logic diagram can be avoided, and meanwhile, the confidentiality requirement of logic internal implementation is met because only the target file is needed by using the self-defined function block.

When the target file of the complete logical page of the industrial controller is generated, the complete target file only comprises the target file of the common logical block and does not comprise the target file of the custom logical block, so that the data volume of the complete target file corresponding to the complete logical page is effectively reduced, and the occurrence probability of file expansion is reduced; in addition, by means of the control information, the user-defined logic block can be accurately called when the user-defined logic block is executed, and the execution of the target file of the user-defined logic is ensured.

The calling library can adopt a link calling library to realize the calling of the target file of the custom logic block, and the aim of calling the target file of the custom logic block by using the identification information is realized by setting the corresponding relation between the target file of the custom logic block and the preset identification information.

In an exemplary embodiment, said executing said complete object file in said industrial controller comprises:

when the complete target file is analyzed, if the complete target file is detected not to include the target file of the logic block to be executed, acquiring the control information of the logic block to be executed;

acquiring a target file of the logic block to be executed from the industrial controller according to the control information;

creating a new logical page corresponding to the target file of the logical block to be executed on the logical page executing the complete target file;

and processing the target file of the logic block to be executed on the newly created logic page.

And simultaneously downloading the target files of the logic page and the custom logic block to the controller, calling the target file of the custom logic block when the controller executes the custom logic block in the logic page, generating a virtual logic page in the memory, and executing.
