善,適用性強(qiáng)PLC發(fā)展到今天,已經(jīng)形成了大、中、小各種規(guī)模的系列化產(chǎn)品。在應(yīng)用軟件中,應(yīng)用者還可以編入外圍器件的故障自診斷程序,使系統(tǒng)中除PLC以外的電路及設(shè)備也獲得故障自診斷保護(hù)。從PLC的機(jī)外電路來說,使用PLC構(gòu)成控制系統(tǒng),和同等規(guī)模的繼電接觸器系統(tǒng)相比,電氣接線及開關(guān)接點(diǎn)已減少到數(shù)百甚至數(shù)千分之一,故障也就大大降低。 PLC的特點(diǎn)(1)可靠性高,抗干擾能力強(qiáng)高可靠性是電氣控制設(shè)備的關(guān)鍵性能。PLC是一種專門為在工業(yè)環(huán)境下應(yīng)用而設(shè)計(jì)的數(shù)字運(yùn)算操作的電子裝置。 WinCC。 The third part is mainly to the water cinder flushing system is introduced and the experimental research drawings。關(guān)鍵詞:PLC;WinCC;畫面窗口46 / 49AbstractAt present PLC has bee the standard of industrial control equipment, automatic control system is one of the pillars of the three technology, the application in automatic control system, PLC holds an important position.This design is the content of the Siemens S7300 series in programming software and programming environment water cinder flushing system programming design and PC control screen design. In the master S7300 ladderdiagram programming and characteristics and WinCC PC programming, under the premise of the system overall design, repeated test. In the picture window shows WinCC is consistent with PLC operation of the process and result, make the abstract program clearly show and eyes.This paper is divided into four parts: the first part of main water cinder flushing system design of the related knowledge are introduced。本論文大致可分為四個(gè)部分:第一部分主要對(duì)水沖渣系統(tǒng)設(shè)計(jì)的相關(guān)知識(shí)做了介紹;第二部分介紹了PLC的基本組成和工作原理及PLC在自動(dòng)化系統(tǒng)中的應(yīng)用;第三部分主要是對(duì)水沖渣系統(tǒng)圖紙介紹及實(shí)驗(yàn)調(diào)研;最后一部分是水沖渣系統(tǒng)的軟件敘述。在熟練掌握S7300梯形圖編程及特點(diǎn)和WinCC上位機(jī)編程的前提下,對(duì)該系統(tǒng)進(jìn)行全面設(shè)計(jì),反復(fù)試驗(yàn)。摘 要目前PLC 己成為工業(yè)控制的標(biāo)準(zhǔn)設(shè)備,是自動(dòng)控制系統(tǒng)的三大技術(shù)支柱之一, 在自動(dòng)控制系統(tǒng)的應(yīng)用中,可編程序控制器占據(jù)著舉足輕重的地位。在WinCC畫面窗口中顯示出與PLC運(yùn)行相一致的過程和結(jié)果,使抽象的程序一目了然地展現(xiàn)與眼前。本論文所設(shè)計(jì)軟件可用于PLC和WinCC的模擬運(yùn)行與學(xué)習(xí),經(jīng)進(jìn)一步完善和擴(kuò)充功能也可作為基于計(jì)算機(jī)平臺(tái)控制技術(shù)的基礎(chǔ)。 The second part introduces the basic position of PLC and working principle and the application of PLC in automation system。 The last part is the water cinder flushing system paper narrative.This paper design software can be used for simulation of the PLC and WinCC operation and study, the further improvement and extend the functionality can be used as a platform based on puter control technology foundation.Key words: PLC。 Picture window目 錄1 序言 1 PLC的定義 1 PLC的特點(diǎn) 1 PLC的應(yīng)用領(lǐng)域 2 選題背景和意義 3 本文主要研究對(duì)象和工作任務(wù) 42 Step7編程軟件介紹 5 Step7編程軟件簡(jiǎn)介 5 Step7編程軟件使用步驟 5 建立新項(xiàng)目 5 硬件組態(tài) 9 編寫程
