基于PLC的加工中心控制系统的设计 摘要 可编程控制器’S CONTROL THE SYSTEMS Abstract Applied meaning that programmable controller have in its control the aspect in the industry gradually obvious, combine at generate electricity, chemical engineering, electronics etc. profession craft the equipmentss electricity control the aspect got the extensive application.It have the function strong and big, the usage is dependable, maintain the many advantage of simple etc., and already and gradually replaced after the logic control of the electric appliances electric circuit in a lot of places. But what the text discuss is a PLC in the actual industry to control the systems application.Heavy work limited company of JiangNan is because of the industrial structure that variety that development, decision establish a stalk to process the center is on originally possessed of the foundation that the machine manufacturing the cent the factory with the business.Because whole stalk process the center is at gradually developments with in the ameliorative process, the many design still did not put into execution.This text only passes the some set equipments the electricity control the systems of in a specific way reform to be used as the point to launch the description.The network correspondence of whole center manages with the network this text will make the first steps description in the fourth, chapter 5 with study. Key word:Programmable controller, A1SJ71E71, the multi-line order , Socket word 目录 摘要 1 Abstract 2 第一章：绪论 5 1.1：PLC技术基本原理 5 1.1.1.PLC的体系结构 5 1.1.2.PLC的工作原理 7 1.2：江南重工轴系加工现场控制系统的设计概述 8 1.3：本文内容简介 8 第二章：A系列PLC的特点及其通信 9 2.1：A系列PLC 9 2.1.1 A系列PLC的主要特点 9 2.1.2.PLC的编程语言和指令 9 2.2：PLC的MELSECNET网络通信 11 2.2.1.
