摘　　要：软PLC技术的发展解决了传统PLC开放性差、通用性差以及难以形成开放式的硬件体系结构等缺点,其以PC机作为硬件平台,可以充分利用PC机丰富的软硬件资源,且可以为用户提供友好的编程界面。软PLC技术的实现包括编辑环境及运行环境。本文将介绍基于控制器平台的运行环境的设计,论述了软PLC系统的框架设计及运行环境的硬件及软件的框架设计,并分析PLC运行环境的执行原理。为后续实现软PLC系统运行环境的功能奠定了基础。The development of soft PLC technology solved the poor openness and universality of traditional PLC as well as difficulty in forming hardware architecture of open mode. Soft PLC is based on PC hardware and make full use of hardware and software resources to provide a friendly programming UI. The implementation of Soft PLC include programming editing and running environment. This paper introduced how to design the runtime environment based on controller platform, discuss the design methods including the framework of soft PLC system and the framework of running environment＇s software and hardware. Besides, this paper also analyzed the implementation of the runtime environment, which laid solid foundation for the implementation of soft PLC running environment.
