描述

P0916PWOC

可編程序控制器的英文為ProgrammableController,在二十世紀(jì)70-80年代一直簡(jiǎn)稱為PC。由于到90年代,個(gè)人計(jì)算機(jī)發(fā)展起來(lái),也簡(jiǎn)稱為PC;加之可編程序的概念所涵蓋的范圍太大,所以美國(guó)AB公司首次將可編程序控制器定名為可編程序邏輯控制器(PLC-ProgrammableLogicController),為了方便,仍簡(jiǎn)稱PLC為可編程序控制器。有人把可編程序控制器組成的系統(tǒng)稱為PCS可編程序控制系統(tǒng),強(qiáng)調(diào)可編程序控制器生產(chǎn)廠商向人們提供的已是完整的系統(tǒng)了。

1968年美國(guó)GM(通用汽車)公司提出取代繼電器控制裝置的要求,第二年美國(guó)數(shù)字公司研制出了第一代可編程序控制器,滿足了GM公司裝配線的要求。隨著集成電路技術(shù)和計(jì)算機(jī)技術(shù)的發(fā)展,現(xiàn)在已有第五代PLC產(chǎn)品了。
在以改變幾何形狀和機(jī)械性能為特征的制造工業(yè)和以物理變化和化學(xué)變化將原料轉(zhuǎn)化成產(chǎn)品為特征的過(guò)程工業(yè)中,除了以連續(xù)量為主的反饋控制外,特別在制造工業(yè)中存在了大量的開關(guān)量為主的開環(huán)的順序控制,它按照邏輯條件進(jìn)行順序動(dòng)作號(hào)按照時(shí)序動(dòng)作;另外還有與順序、時(shí)序無(wú)關(guān)的按照邏輯關(guān)系進(jìn)行連鎖保護(hù)動(dòng)作的控制;以及大量的開關(guān)量、脈沖量、計(jì)時(shí)、計(jì)數(shù)器、模擬量的越限報(bào)警等狀態(tài)量為主的—離散量的數(shù)據(jù)采集監(jiān)視。由于這些控制和監(jiān)視的要求,所以PLC發(fā)展成了取代繼電器線路和進(jìn)行順序控制為主的產(chǎn)品。在多年的生產(chǎn)實(shí)踐中,逐漸形成了PLC、DCS與IPC三足鼎立之勢(shì),還有其它的單回路智能式調(diào)節(jié)器等在市場(chǎng)上占一定的百分比。
在80年代至90年代中期,是PLC發(fā)展最快的時(shí)期,年增長(zhǎng)率一直保持為30~40%。由于PLC機(jī)聯(lián)系處理模擬能力和網(wǎng)絡(luò)方面功能的進(jìn)步,擠占了一部分DCS的市場(chǎng)(過(guò)程控制)并逐漸壟斷了污水處理等行業(yè),但是由于工業(yè)PC(IPC)的出現(xiàn),特別是近年來(lái)現(xiàn)場(chǎng)總線技術(shù)的發(fā)展,IPC和FCS也擠占了一部分PLC市場(chǎng),所以近年來(lái)PLC增長(zhǎng)速度,總的說(shuō)是漸緩。目前全世界有200多廠家生產(chǎn)300多品種PLC產(chǎn)品,主要應(yīng)用在汽車(23%)、糧食加工(16.4%)、化學(xué)/制藥(14.6%)、金屬/礦山(11.5%)、紙漿/造紙(11.3%)等行業(yè)。

選擇深圳長(zhǎng)欣,選擇放心,售后無(wú)憂大量現(xiàn)貨,當(dāng)天順豐發(fā)貨!
主營(yíng):本特利,英維思,伍德沃德,??怂共_、西屋、瑞恩、施耐德莫迪康、ABB、AB、西門子、摩托羅拉、GE發(fā)那科、安川、博世力士樂(lè),ACSO,力士樂(lè)等各大品牌的DCS系統(tǒng)配件,機(jī)器人系統(tǒng)配件,大型伺服系統(tǒng)備件。

先介紹幾點(diǎn)經(jīng)驗(yàn)。
1、先通讀一遍“系統(tǒng)手冊(cè)”(不管能不能看懂,先了解個(gè)大概,以便學(xué)習(xí)編程時(shí)查找);
2、由位控邏輯入手,逐漸增加定時(shí)、計(jì)數(shù)等條件,把或、與、非關(guān)系理順;
3、進(jìn)而練習(xí)整數(shù)運(yùn)算、實(shí)數(shù)運(yùn)算、類型轉(zhuǎn)換;
4、量程轉(zhuǎn)換、PID調(diào)節(jié)回路的建立及P、I、D參數(shù)的理解(最好是有個(gè)物理回路驗(yàn)證,比如變頻器+電機(jī)+測(cè)速傳感器);
5、循環(huán)、順序、跳轉(zhuǎn)等程序控制(盡量避免跳轉(zhuǎn),非跳不可時(shí)也是跳的越近越好);
6、中斷、通訊、位置控制....

本人以ABB工業(yè)機(jī)器人配件DSQC系列和Motorola MVME系列,GE 卡件 模塊 驅(qū)動(dòng)器系列為主攻。各位電工朋友可根據(jù)自己的條件選擇適合自己的PLC品牌,由于PLC的基本框架大同小異,學(xué)會(huì)一種至于其它的學(xué)習(xí)起來(lái)也就簡(jiǎn)單了。
