摘要目前PLC己成为工业控制的标准设备,是自动控制系统的三大技术支柱之一,在自动控制系统的应用中,可编程序控制器占据着举足轻重的地位。本次设计的内容是在西门子S7300系列编程软件及WinCC6.2编程环境下对水冲渣系统进行的编程设计及上位机控制画面设计。在熟练掌握S7300梯形图编程及特点和WinCC上位机编程的前提下，对该系统进行全面设计，反复试验。在WinCC画面窗口中显示出与PLC运行相一致的过程和结果，使抽象的程序一目了然地展现与眼前。本论文大致可分为四个部分：第一部分主要对水冲渣系统设计的相关知识做了介绍；第二部分介绍了PLC的基本组成和工作原理及PLC在自动化系统中的应用；第三部分主要是对水冲渣系统图纸介绍及实验调研；最后一部分是水冲渣系统的软件叙述。本论文所设计软件可用于PLC和WinCC的模拟运行与学习，经进一步完善和扩充功能也可作为基于计算机平台控制技术的基础。关键词：PLC；WinCC；画面窗口AbstractAtpresentPLChasbecomethestandardofindustrialcontrolequipment,automaticcontrolsystemisoneofthepillarsofthethreetechnology,theapplicationinautomaticcontrolsystem,PLCholdsanimportantposition.ThisdesignisthecontentoftheSiemensS7300seriesinprogrammingsoftwareandwincc6.2programmingenvironmentwatercinderflushingsystemprogrammingdesignandPCcontrolscreendesign.InthemasterS7300ladder-diagramprogrammingandcharacteristicsandWinCCPCprogramming,underthepremiseofthesystemoveralldesign,repeatedtest.InthepicturewindowshowsWinCCisconsistentwithPLCoperationoftheprocessandresult,maketheabstractprogramclearlyshowandeyes.Thispaperisdividedintofourparts:thefirstpartofmainwatercinderflushingsystemdesignoftherelatedknowledgeareintroduced;ThesecondpartintroducesthebasiccompositionofPLCandworkingprincipleandtheapplicationofPLCinautomationsystem;Thethirdpartismainlytothewatercinderflushingsystemisintroducedandtheexperimentalresearchdrawings;Thelastpartisthewatercinderflushingsystempapernarrative.ThispaperdesignsoftwarecanbeusedforsimulationofthePLCandWinCCoperationandstudy,thefurtherimprovementandextendthefunctionalitycanbeusedasaplatformbasedoncomputercontroltechnologyfoundation.Keywords:PLC;WinCC;Picturewindow目录1序言.....................................................................11.1PLC的定义...........................................................11.2PLC的特点...........................................................11.3PLC的应用领域.......................................................21.4选题背景和意义......................................................31.5本文主要研究对象和工作任务..........................................42Step7编程软件介绍........................................................52.1Step7编程软件简介...................................................52.2Step7编程软件使用步骤...............................................52.2.1建立新项目........................................................52.2.2硬件组态..........................................................92.2.3编写程序.........................................................122.2.4调试运行.........................................................143WinCC组态软件介绍.......................................................153.1WinCC组态软件简介..................................................153.2WinCC简单使用步骤..................................................154水冲渣系统设计图纸......................................................174.1设计系统过程控制流程图.............................................174.2设计冲渣水泵系统的PLC硬件结构图.......
