Problems solved by technology

This PLC programming method requires programmers to manually analyze and process the data of the application object, and the programming efficiency is not high; at the same time, when the process parameters of the application object change, it cannot flexibly respond to the corresponding process modification
Finally, there is also the problem of inconsistency in the implementation of norms among multiple sets of procedures

Abstract

The invention discloses a PLC program generation method, and the method comprises a step of making a PLC program template: making a universal PLC program template for common application objects basedon the common application objects; a step of making a project reference file: making a project reference file formed by a single project parameter based on a single project implementation target; a step of generating a PLC program source file: importing the PLC program template and the project reference file into a PLC program generation tool, and generating a PLC program source file according toa selected PLC brand; and a step of generating a PLC program: importing the PLC program source file into PLC programming software, and generating the PLC program. The invention also discloses a PLC program generation system. The method and system provided by the invention can greatly improve the automation of the PLC programming, and improve the PLC programming efficiency.

Description

technical field [0001] The invention relates to the field of programmable logic controllers, in particular to a method and system for generating programs for programmable logic controllers. Background technique [0002] PLC (Programmable Logic Controller, Programmable Logic Controller) is a new generation of microprocessor-based industrial automatic control device specially designed for application in industrial environments. It uses a programmable memory to store instructions for performing logic operations, sequence control, timing, counting, and arithmetic operations, and controls various types of mechanical equipment or production through digital or analog input and output. process. [0003] When programming the PLC, it is necessary to design and adjust the PLC program according to the type and quantity of the application objects. This PLC programming method requires programmers to manually analyze and process the data of the application object, and the programming eff...
