摘 要
本论文首先从PLC的发展为切入点，介绍PLC在现今的自动化控制中的巨大作用。在PLC控制系统中应用现场总线技术实现PLC与现场设备、客户端、服务器间实时通信，达到分散优化综合控制是工业控制领域的热门问题。综合控制系统设计的优良直接影响着工业生产的经济性。深入研究应用PLC及现场总线控制技术会为我国在工业自动化领域 的进一步发展做出有益贡献。
随着柔性制造技术、计算机集成制造技术和信息技术的发展，当今世界制造业即将进入全盘自动化的时代，自动化制造系统的实施标志着人类进入了现代文明生产的新纪元。交流伺服系统因响应速度快、速度精度高、调速范围宽、加减速性能好等特点，在制造业控制中得到了广泛的应用，逐渐成为工业自动化领域中运动控制的主流。
本论文在分析了PLC与伺服控制在自动化控制中的有效结合将给自动化控制带来莫大的好处后，本文从分析PROFIBUS现场总线技术入手，研究PROFIBUS- DP协议及其报文结构，阐述SIMATIC S7-200系列PLC中PROFIBUS总线的应用。在原有电线生产线电气原理图基础上，用PLC取代原有继电控制系统，完成了硬件选型，程序块定义及梯形图程序编辑及仿真调试、下载，同时利用西门子公司WinCC软件实现了上位机与PLC的通讯，完成了电线生产线监控系统的设计。
这次研究的目的在于研究基于S7-200的伺服电机系统的设计，包括PLC的系统设计，伺服放大器与伺服电机、继电器与电机控制系统的设计。

ABSTRACT
In this paper, first of all, from the entry point for the development of PLC, PLC, introduced in today’s automation and control of the tremendous role. In the PLC control system PLC fieldbus technology equipment and on-site, client, server, real-time communication between to decentralized optimization control is a hot field of industrial control problem. Integrated quality control system designed to directly affect the economics of industrial production. Depth study of the application of PLC and fieldbus control technology for our country in the field of industrial automation to make a useful contribution to further development。
With flexible manufacturing technology, computer integrated manufacturing technology and information technology, the manufacturing sector in today''s world is about to enter an era of full automation, the implementation of automated manufacturing systems of human production has entered a new era of modern civilization. AC servo system in response to fast speed and high precision, wide speed range, good speed performance characteristics of control in the manufacturing sector has been widely used, has gradually become the field of industrial automation control of the mainstream movement。
In this paper, the analysis of the PLC and servo control in the automatic control of the effective integration of automation and control would bring enormous benefits, this article from the analysis of the technical aspect PROFIBUS fieldbus, PROFIBUS-DP protocol research and message structure, the SIMATIC S7-200 series PLC in the bus PROFIBUS applications. Production lines in the original electrical wiring schematic diagram based on the use of PLC control system to replace the relay to complete the selection of hardware, block definition and simulation ladder program editing and debugging, downloading, to achieve the wire production line PLC control; At the same time, the use of Siemens WinCC software implementation of the host computer and the PLC communications, the completion of the wire production line monitoring and control system design。
The purpose of this study is to examine the S7-200 based on the servo motor system design, system design, including PLC, servo amplifier and servo motor, relay and motor control system design。
Keywords: PLC Servo control PROFIBUS Anti-jamming
