摘要
随着信息技术的不断发展,信息交换技术覆盖了各行各业。在自动化领域,越来越多的企业需要建立包含从工厂现场设备层到控制层、管理层等各个层次的综合自动化网络管控平台,建立以工业控制网络技术为基础的企业信息化系统。传统的PLC仿真技术只限于单机的PLC控制,模拟程序运行,其有一个致命的缺点就是不能进行网络仿真。随着工业网络通讯的普及,对网络仿真的需求越来越大。本文将着重讲述如何通过PLCSIM V5.4进行西门子工业以太网的网络通讯仿真。
With the continuous development of information technology,information exchange technologies cover all fields.In the field of automation,more and more companies need to build integrated control platform for automation network from field devices to control level and management level.However,enterprise information system based on industrial control network is also required.Traditional PLC simulation technology is limited to stand-alone PLC control and simulation which has a fatal flaw that PLC can not simulate network communication.With the popularity of industrial network communications,the growing network simulation is demanded.This paper will focus on how to carry out network communication simulation with Siemens Industrial Ethernet through software PLCSIM V5.4.
