Soft PLC configuration development method based on XML technology

Abstract

The invention discloses a soft PLC configuration development method based on XML technology, including the steps: abstracting and packaging basic components of a PLC graphic program in an object-oriented manner to obtain primitive components; according to the type of the primitive components, creating a corresponding project; constructing a PLC configuration development environment, and loading acorresponding primitive component library; maintaining the primitive components, and arranging and combining the primitive components by dragging in the way of graph visualization; configuring the attributes and parameters of the primitive components, and establishing the connection relationship between the primitive components; storing the attributes and logic relationships of the primitive components, and according to TC6_XML_V201. Xsd file, describing a configuration PLC graphic program to obtain an XML file according with the IEC61131 standard; converting the XML file into an instruction table or structured text; generating a source file and further generating a target file; and deploying the target file to the running system of soft PLC to complete the development of the whole soft PLC system. The invention can effectively improve the efficiency and flexibility of soft PLC development.

Description

technical field [0001] The invention belongs to the field of soft PLC (Programmable Logic Controller, programmable logic controller) configuration, and more specifically, relates to a soft PLC configuration development method based on XML (Extensible Markup Language, Extensible Markup Language) technology. Background technique [0002] Under the influence of the rapid development of computer technology, soft PLC development technology has been popularized and applied in the field of industrial automation. The efficiency of soft PLC development has been widely concerned, but the products of various PLC manufacturers are not compatible with each other, and the development tools used are not uniform in data format. Users need to support corresponding development tools while using PLC hardware. Completing relevant development work, this makes the compatibility and scalability of soft PLC development very poor, and cannot meet the requirements of open development of industrial au...

Problems solved by technology

The efficiency of soft PLC development has been widely concerned, but the products of various PLC manufacturers are not compatible with each other, and the development tools used are not uniform in data format. Users need to support corresponding development tools while using PLC hardware. Complete related development work, which makes the compatibility and scalability of soft PLC development very poor, and cannot meet the requirements of open development of industrial automation systems

[0003] Although the modern software module design principles adopted by the existing IEC61131-3 standard support modular development and object-oriented programming concepts make the PLC development system have good openness, there is still no unified project information for PLC development tools The standardized format cannot achieve the reusability of PLC graphics programs
