plc变频器协同控制电机转速plc变频器协同控制电机转速/NUMPAGES55plc变频器协同控制电机转速摘要PLC和变频器是工厂实现远程控制，提高生产效率的重要硬件。采用PLC的优点就在于PLC的程序编制过程不是很复杂.而组态软件又使得工厂在生产过程中能够远程监控设备的运行，能够及时有效的处理突发事件。组态王控制功能强大，界面创建简单,编写程序方便,有利于初学者使用。本次设计是在熟悉KINGVIEW组态王、S7—200编程软件、西门子MM420变频器、以及USS通信协议的基础上完成的。本文主要体现了，PLC与变频器之间利用USS协议连接起来，共同控制电动机调速，最终要实现的是利用组态王的监控界面可以改变PLC的打开/闭合,能够监控电机的运转画面。文中重点介绍了组态王界面的制作及参数的设置、USS协议的应用、PLC程序的编写过程及参数设置、变频器的参数设置、PLC与变频器的通信等.b5E2RGbCAP关键词：PLC；变频器；USS通信协议；组态王AbstractPLCandtransducerisimportanthardwarewhichrealizeslongcontrolandimprovetheyieldinthefactory。PLC’SmeritsconsistthatweavingPLC’Sprogramsaren’tveryhard。Kingviewmakethefactorycanwatchandcontroltherunningfacilitiesbetweentheproducingprocesses，alsodealwithmatterswhichbreakoutinseason。Thekingviewhaspowerfulcontrolfunction，itsetteesupinterfacesveryeasy，itwritesprogramseasy，anditispropitioustousingfornovice。p1EanqFDPwInthisdesigniscompletedonthebasesofknowingKINGVIEW,s7-200programmingsoftware，SIEMENSEMM420,transducerandUSScommunicationprotocol.ThisessaymainlymaterializesthatPLClinkedupwithtransducer，makinguseofUSScommunicationprotocol.Theycontrolledthespeedofelectromotor。FinallywewellrealizedtheinterfaceofkingviewandcanchangePLC’son/off，andthenwecansuperviseandcontroltheworkingmenuofelectromotor。Inthisessay，Iintroducethefactureofkingviewandtheparameter’ssettingofkingview,theapplicationofUSSprotocol，thewritingprocessofthePLC’sprogramandparametersetting，theparametersettingoftransducer,communicationbetweenPLCandtransducer,etc.DXDiTa9E3dKeywords：PLC。transducer。USScommunicatingprotocol。kingviewRTCrpUDGiT目录TOC\o"1-3”\h\z\uHYPERLINK\l”_Toc201909214”1引言PAGEREF_Toc201909214\h15PCzVD7HxAHYPERLINK\l”_Toc201909215"1。1课题背景及设计研究方向PAGEREF_Toc201909215\h1jLBHrnAILgHYPERLINK\l”_Toc201909216”1。1。1课题背景PAGEREF_Toc201909216\h1xHAQX74J0XHYPERLINK\l”_Toc201909217"1.1.2设计研究方向PAGEREF_Toc201909217\h2LDAYtRyKfEHYPERLINK\l”_Toc201909218”2PLC可编程控制器PAGEREF_Toc201909218\h3Zzz6ZB2LtkHYPERLINK\l"_Toc201909219”2。1可编程控制器梯形图编程规则PAGEREF_T
