描述

A20B-2902-0290/08C

PLC是一種工業(yè)控制系統(tǒng),它的控制對(duì)象是工業(yè)生產(chǎn)設(shè)備或工業(yè)生產(chǎn)過程,工作環(huán)境是工業(yè)生產(chǎn)現(xiàn)場(chǎng)。它與工業(yè)生產(chǎn)過程的聯(lián)系是通過I/O接口模塊來實(shí)現(xiàn)的。

通過I/O接口模塊可以檢測(cè)被控生產(chǎn)過程的各種參數(shù),并以這些現(xiàn)場(chǎng)數(shù)據(jù)作為控制信息對(duì)被控對(duì)象進(jìn)行控制。同時(shí)通過I/O接口模塊將控制器的處理結(jié)果送給被控設(shè)備或工業(yè)生產(chǎn)過程,從而驅(qū)動(dòng)各種執(zhí)行機(jī)構(gòu)來實(shí)現(xiàn)控制。PLC從現(xiàn)場(chǎng)收集的信息及輸出給外部設(shè)備的控制信號(hào)都需經(jīng)過一定距離,為了確保這些信息的正確無誤,PLC的I/O接口模塊都具有較好的抗干擾能力。根據(jù)實(shí)際需要,一般情況下,PLC都有許多I/O接口模塊,包括開關(guān)量輸入模塊、開關(guān)量輸出模塊、模擬量輸入模塊、模擬量輸出模塊以及其它一些特殊模塊,使用時(shí)應(yīng)根據(jù)它們的特點(diǎn)進(jìn)行選擇。

?1.DCS是一種“分散式控制系統(tǒng)”,而PLC(可編程控制器)只是一種控制“裝置”,兩者是“系統(tǒng)”與“裝置”的區(qū)別。系統(tǒng)可以實(shí)現(xiàn)任何裝置的功能與協(xié)調(diào),PLC裝置只實(shí)現(xiàn)本單元所具備的功能。
? ? 2.在網(wǎng)絡(luò)方面,DCS網(wǎng)絡(luò)是整個(gè)系統(tǒng)的中樞神經(jīng),它是安全可靠雙冗余的高速通訊網(wǎng)絡(luò),系統(tǒng)的拓展性與開放性更好。而PLC因?yàn)榛旧隙紴閭€(gè)體工作,其在與別的PLC或上位機(jī)進(jìn)行通訊時(shí),所采用的網(wǎng)絡(luò)形式基本都是單網(wǎng)結(jié)構(gòu),網(wǎng)絡(luò)協(xié)議也經(jīng)常與國(guó)際標(biāo)準(zhǔn)不符。在網(wǎng)絡(luò)安全上,PLC沒有很好的保護(hù)措施。我們采用電源,CPU,網(wǎng)絡(luò)雙冗余。
? ? 3.DCS整體考慮方案,操作員站都具備工程師站功能,站與站之間在運(yùn)行方案程序下裝后是一種緊密聯(lián)合的關(guān)系,任何站、任何功能、任何被控裝置間都是相互連鎖控制,協(xié)調(diào)控制;而單用PLC互相連接構(gòu)成的系統(tǒng),其站與站(PLC與PLC)之間的聯(lián)系則是一種松散連接方式,是做不出協(xié)調(diào)控制的功能。
? ? 4.DCS在整個(gè)設(shè)計(jì)上就留有大量的可擴(kuò)展性接口,外接系統(tǒng)或擴(kuò)展系統(tǒng)都十分方便,PLC所搭接的整個(gè)系統(tǒng)完成后,想隨意的增加或減少操作員站都是很難實(shí)現(xiàn)的。

15天包退換 一年質(zhì)保 大量現(xiàn)貨? 國(guó)內(nèi)實(shí)力庫(kù)存商家


選擇深圳長(zhǎng)欣,選擇放心,售后無憂大量現(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,ACSO,力士樂等各大品牌的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)起來也就簡(jiǎn)單了。
