描述

1769-L30ER

?PLC技術(shù)之所以高速發(fā)展，除了工業(yè)自動(dòng)化的客觀需要外，主要是因?yàn)樗哂性S多獨(dú)特的優(yōu)點(diǎn)。它較好地解決了工業(yè)領(lǐng)域中普遍關(guān)心的可靠、安全、靈活、方便、經(jīng)濟(jì)等問(wèn)題。主要有以下特點(diǎn)：
? ? 1．可靠性高、抗干擾能力強(qiáng)
? ? 可靠性高、抗干擾能力強(qiáng)是PLC最重要的特點(diǎn)之一。PLC的平均無(wú)故障時(shí)間可達(dá)幾十萬(wàn)個(gè)小時(shí)，之所以有這么高的可靠性，是由于它采用了一系列的硬件和軟件的抗干擾措施：
? ? （1）硬件方面I/O通道采用光電隔離，有效地抑制了外部干擾源對(duì)PLC的影響；對(duì)供電電源及線路采用多種形式的濾波，從而消除或抑制了高頻干擾；對(duì)CPU等重要部件采用良好的導(dǎo)電、導(dǎo)磁材料進(jìn)行屏蔽，以減少空間電磁干擾；對(duì)有些模塊設(shè)置了聯(lián)鎖保護(hù)、自診斷電路等。
? ? （2）軟件方面PLC采用掃描工作方式，減少了由于外界環(huán)境干擾引起故障；在PLC系統(tǒng)程序中設(shè)有故障檢測(cè)和自診斷程序，能對(duì)系統(tǒng)硬件電路等故障實(shí)現(xiàn)檢測(cè)和判斷；當(dāng)由外界干擾引起故障時(shí)，能立即將當(dāng)前重要信息加以封存，禁止任何不穩(wěn)定的讀寫操作，一旦外界環(huán)境正常后，便可恢復(fù)到故障發(fā)生前的狀態(tài)，繼續(xù)原來(lái)的工作。
? ? 2．編程簡(jiǎn)單、使用方便
? ? 目前，大多數(shù)PLC采用的編程語(yǔ)言是梯形圖語(yǔ)言，它是一種面向生產(chǎn)、面向用戶的編程語(yǔ)言。梯形圖與電器控制線路圖相似，形象、直觀，不需要掌握計(jì)算機(jī)知識(shí)，很容易讓廣大工程技術(shù)人員掌握。當(dāng)生產(chǎn)流程需要改變時(shí)，可以現(xiàn)場(chǎng)改變程序，使用方便、靈活。同時(shí)，PLC編程器的操作和使用也很簡(jiǎn)單。這也是PLC獲得普及和推廣的主要原因之一。
? ? 許多PLC還針對(duì)具體問(wèn)題，設(shè)計(jì)了各種專用編程指令及編程方法，進(jìn)一步簡(jiǎn)化了編程。

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(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。
