摘要
经济需要科技的支撑,科技的发展也需要有经济做后盾,近年来,科技的发展体现在各个领域:航空,机械,工程,电子,计算机,汽车,网络。我们进入了数字化的时代,EPA技术在成熟的环境中应运而生。通过工业现场设备开放的网络平台,不仅可以使工业现场设备实现基于以太网的通讯,而且可以使工业现场设备层网络不游离于主流通讯技术之外,并与主流通讯技术同步发展,同时,用以太网现场设备层到控制层、管理层等所有层次网络的“E网到底”,实现工业综合自动化系统各层次的信息高度耦合与集成,推动工业各个领域的技术革新。本文主要通过使用目前国内唯一一个拥有自主知识产权的EPA协议,运用其“与、或、非、定时器、调用子程序”等功能块语言进行编程。实现对模拟交通灯的控制,同时运用北京力控组态软件对控制过程进行组态。实现了通过以太网对实时交通灯的控制。

Abstract
Economy needs the support of science and technology, technological development also need to have financial backing in recent years, the development of technology embodied in the various fields: aviation, machinery, engineering, electronics, computer, automotive, networking. We enter the digital era, EPA technology came into being in a mature environment. Industrial field device through the work platform, not only the industrial field devices can be -munication, but also the industrial field device work is not divorced from the mainstream munications technologies, and the simultaneous development munication technologies with the mainstream, while field devices using the layer to control layer, network management and all levels "work in the end," integrated automation system of industrial information at various levels coupled with a high degree of integration, the promotion of industrial technology innovation in various fields. In this paper, by using the currently the only EPA with independent intellectual property rights agreements, the use of its "and, or, not, timer, call the subroutine" and function block programming language. To achieve control of the simulation of traffic lights, while the use of force Beijing control configuration software configuration control process. Achieve real-time control of traffic lights.
Key words:traffic light; EPA ;programming control; configuration
