Abstract: The hardware and software design platform of embedded soft PLC is presented. Embedded soft PLC system for industrial control is developed by the techniques of ladder diagram, hardware interface mapping and modular design. This system is composed of development system and operating system. The development system translates the programs based on graphics language into target code, and the operating system loads the target code and executes command based on the code to control the system.

Key words: embedded soft PLC, ladder diagram, mapping technology

摘要： 介绍嵌入式软PLC硬件设计平台和软件设计平台，利用梯形图、硬件接口映射及模块化设计技术开发面向工业控制嵌入式软PLC系统。软PLC系统由开发系统和运行系统组成，其中开发系统将程序翻译成目标代码，运行系统加载目标代码，根据目标代码执行指令，实现控制功能。
