First, an application scenario of the present invention is described:
when developers develop standardized configuration files capable of running on each PLC platform, PLC program development can be carried out by utilizing PLC language standards, and only the generation device of the configuration files of the programmable logic controller needs to be input after the program development is finished. Then, the generating device of the configuration file of the programmable logic controller firstly carries out normalization processing on the input PLC program to generate a first configuration file containing a preset configuration file structure, and then inputs the first configuration file into the generator to enable the standardized generator to output a second configuration file which meets the first file description specification preset by the standardized generator. The execution subject related in the embodiment of the present invention is the generation apparatus of the configuration file of the programmable logic controller.
Fig. 1 is a schematic flowchart of a method for generating a configuration file of a programmable logic controller according to an embodiment of the present invention.
Referring to fig. 1, the method for generating the configuration file of the plc includes steps S11-S13, which are as follows:
s11: and acquiring a programmable logic controller program file input by a user.
The programmable logic controller program file can be a program file which is programmed and designed by a developer through a PLC programming language according to the control requirement of a control system.
The PLC programming language may specifically include a ladder diagram Language (LD), an instruction list language (IL), a function block diagram language (FBD), a sequential function flow diagram language (SFC), a structured text language (ST), and the like.
In practical application, a developer can develop a PLC program file on any PLC software platform, and in the development process, the PLC program file only needs to support IEC61131-3 language standard (the language standard of a programming system formulated by International electrotechnical Commission), and only needs to be sent to a generating device of a configuration file of a programmable logic controller after the development is completed, and the program file does not need to be stored as an XML file according to the standard like the prior art, so that the development difficulty of the developer is reduced.
S12: and carrying out normalization processing on the programmable logic controller program file to generate a first configuration file of the programmable logic controller program file, wherein the first configuration file comprises a preset configuration file structure.
The configuration file may be an XML file.
The first configuration file may specifically be an XML file having a unified XML structure.
The normalization process may be to convert a dimensional expression into a dimensionless expression, i.e., into a scalar quantity.
In practical application, after acquiring the PLC program files of different platforms, the device for generating the configuration file of the programmable logic controller performs normalization processing on the PLC program files, and generates a first configuration file, so that the first configuration file conforms to a preset configuration file structure, where the preset configuration file structure may be a unified XML structure. The unified XML structure specifies the structure of a non-standard XML file. Compared with standard files, the structure is more in line with the habits of software developers, and is easy for the software developers to convert. Meanwhile, the unified XML structure contains the ADDdata node, so that software developers can define undefined contents in the standard class conveniently.
S13: and taking the first configuration file as the input of the generator, and acquiring a second configuration file of the programmable logic controller program file output by the generator, wherein the generator is preset with a first file description specification, and the second configuration file conforms to the first file description specification.
A generator, comprising: a class file generation layer, an instance object creation layer, an element assignment layer and a serialization layer;
the class file generation layer is used for converting the mode file into the class file by using a mode tool;
the instance object creating layer is used for generating an instance object containing corresponding elements according to the elements in the class file;
the element assignment layer is used for assigning the elements in the instance object according to the first configuration file;
the serialization layer is used for serializing the instance object and generating the second configuration file.
According to the actual situation, for example, the schema file may be an XSD file, and if the XSD file includes FileHeader, ContentHeader, Types, Instances, AddData, and Documentation elements, the class file generation layer of the generator may generate a class file generation layer including FileHeader field, ContentHeader field, typefield, Instances field, and other elements. Then, an instance object creating layer of the generator creates an instance object of the class file, and an element assignment layer assigns values to elements in the instance object according to the first configuration file. Specifically, if the first configuration file is defined by a Function Block, the instance object includes a project types element, and a corresponding item entry of the Function Block type may be generated according to each Function _ Block type child node. And then, grouping the generated Items item group into the ProjectTypes element, and further completing the creation and assignment of the instance object. And finally, serializing the instance object into an XML file through an XmlSerializer to generate a second configuration file.
According to the method for generating the configuration file of the programmable logic controller, the programmable logic controller program file input by the user is obtained and normalized to generate the first configuration file containing the preset configuration file structure, and then the first configuration file is used as the input of the generator to enable the generator to output the second configuration file meeting the first file description specification, so that developers can develop the PLC program without mastering the standardized file description specification, the developed program can generate the configuration file meeting the standardized file description specification through the normalization and the standard generator, and the difficulty in program development of the developers is reduced.

In practical application, before the device for generating the configuration file of the programmable logic controller acquires the PLC program file, a first mode file input by a user needs to be acquired in advance, so that the generator generates a corresponding class file according to a first file description specification in the first mode file.
S23: and acquiring a programmable logic controller program file input by a user.
S24: and carrying out normalization processing on the programmable logic controller program file to generate a first configuration file of the programmable logic controller program file, wherein the first configuration file comprises a preset configuration file structure.
S25: and taking the first configuration file as the input of the generator, and acquiring a second configuration file of the programmable logic controller program file output by the generator, wherein the generator is preset with a first file description specification, and the second configuration file conforms to the first file description specification.

S36: using the second schema file as parameters of the generator to replace the parameters provided by the first schema file and to conform the output of the generator to the second file description specification.
In practical application, if the file description specification of the configuration file is updated, the second configuration file generated after the file description specification is updated is only required to be used as a parameter of the generator, so that the standard generator can generate a new class file according to the second configuration file description specification to replace the original class file. The second configuration file generated by the standardized generator may then conform to the updated file description specification.
