描述

由信號(hào)引入的干擾會(huì)引起I/O信號(hào)工作異常和測量精度大大降低,嚴(yán)重時(shí)將引起元器件損傷。對(duì)于隔離性能差的系統(tǒng),還將導(dǎo)致信號(hào)間互相干擾,引起共地系統(tǒng)總線回流,造成邏輯數(shù)據(jù)變化、誤動(dòng)和死機(jī)。PLC控制系統(tǒng)因信號(hào)引入干擾造成I/O模件損壞數(shù)相當(dāng)嚴(yán)重,由此引起系統(tǒng)故障的情況也很多。

第三類是來自接地系統(tǒng)混亂的干擾。接地是提高電子設(shè)備電磁兼容性(EMC)的有效手段之一,正確的接地既能抑制電磁干擾的影響,又能抑制設(shè)備向外發(fā)出干擾;而錯(cuò)誤的接地反而會(huì)引入嚴(yán)重的干擾信號(hào),使PLC系統(tǒng)無法正常工作。PLC控制系統(tǒng)的地線包括系統(tǒng)地、屏蔽地、交流地和保護(hù)地等,接地系統(tǒng)混亂對(duì)PLC系統(tǒng)的干擾主要是各個(gè)接地點(diǎn)電位分布不均,不同接地點(diǎn)間存在地電位差,引起地環(huán)路電流,影響系統(tǒng)正常工作。例如電纜屏蔽層必須一點(diǎn)接地,如果電纜屏蔽層兩端A、B都接地,就存在地電位差,有電流流過屏蔽層。當(dāng)發(fā)生異常狀態(tài)如雷擊時(shí),地線電流將更大。

我們的優(yōu)勢
公司銷售的進(jìn)口備件從國外生產(chǎn)廠家直接進(jìn)貨,
實(shí)行扁平化的銷售模式,給客戶節(jié)約了時(shí)間和成本。
我們的目標(biāo)就是國內(nèi)用戶采購國外備件遇到困難和疑難時(shí)都能找到我們。
我們能夠及時(shí)地報(bào)出優(yōu)惠的價(jià)格和迅捷的交貨期;國內(nèi)用戶采購國外備件受到獨(dú)家代理壟斷價(jià)格時(shí),我們會(huì)給用戶提供一個(gè)比較的機(jī)會(huì),并且為客戶提供=的解決方案。由于我們的訂單集中,訂貨量大,因此我們能提供頗具競爭力的價(jià)格并能夠迅速交貨,我們長期以來致力于解決國內(nèi)用戶采購國外備件中的疑難問題,并為廣大用戶提供電氣及工控自動(dòng)化成套設(shè)備的購銷、現(xiàn)場調(diào)試等全面周到的服務(wù)。

選擇深圳長欣,選擇放心,售后無憂大量現(xiàn)貨,當(dāng)天順豐發(fā)貨!
主營: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)起來也就簡單了。
