We enter the digital era, EPA technology came into being in a mature environment. Industrial field device through the open network platform, not only the industrial field devices can be Ethernet-based communication, but also the industrial field device level network is not divorced from the mainstream of communications technologies, and the simultaneous development of communication technologies with the mainstream, while field devices using the Ethernet layer to control layer, network management and all levels E network 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 soft
