Description
Technical Field
The invention relates to the technical field of computer software, in particular to a method for developing a PLC graphical editor based on an XML technology.
Background
The programmable controller is well known and widely used by a great number of engineering technicians, in order to adapt to the use requirements and habits of the great number of engineering technicians, the programmable controller does not adopt a programming language of a microcomputer, but adopts a process-oriented and more intuitive programming language, and in the PLC, a graphical programming language ladder diagram is easy to master, popular and easy to understand and is consistent with an electrical control principle diagram, so the programmable controller becomes the main programming language of the PLC. However, the ladder diagram cannot be recognized by the programmable controller and cannot be directly operated. Therefore, how to improve the development efficiency and directly convert the ladder diagram into the PLC instruction becomes a research hotspot of the embedded PLC.
Extensible markup language, a subset of standard generalized markup language, XML for short. Is a markup language for marking electronic documents to be structured. In electronic computers, a label refers to a symbol of information that can be understood by a computer, and by this label, various information such as articles and the like can be handled between computers. It can be used to mark data, define data types, and is a source language that allows a user to define his or her own markup language. It is well suited for world wide web transport, providing a unified approach to describing and exchanging structured data that is independent of the application or vendor. Is a cross-platform, content-dependent technology in the Internet environment and is also an effective tool today for processing distributed structural information. As early as 1998, the XML1.0 specification was published by W3C, which was used to simplify the transmission of Internet documents.
The extensible markup language is different from databases such as Access, Oracle and SQL Server, etc., and the databases provide more powerful data storage and analysis capabilities, such as: data indexing, sorting, finding, relevance, etc., extensible markup language is simply storing data. In fact, it differs most from other forms of data representation: extensible markup language is extremely simple, an advantage that looks somewhat trivial, but it is this that makes it unusual. The simplicity of XML in reading/writing data in any application makes XML quickly the only common language for data exchange, and while different applications will support other data exchange formats as well, they will support XML soon after, meaning that programs can more easily integrate with information generated under Windows, Mac OS, Linux, and other platforms, and then can easily load XML data into the program and parse it and output the results in XML format.
The current graphical programming method of the PLC basically adopts a ladder diagram, but the programming method needs to know the relevant PLC instruction list, and has the defects of inflexibility and easy error when the ladder diagram is edited. The graphic program constructed by the extensibility of the XML technology is simpler, more convenient and more flexible, and only the logical relation of the program blocks similar to the gate circuit needs to be known.
