描述

FOXBORO FBM18

PLC主機(jī)系統(tǒng)最容易發(fā)生故障的地方一般在電源系統(tǒng)和通訊網(wǎng)絡(luò)系統(tǒng)，電源在連續(xù)工作、散熱中，電壓和電流的波動(dòng)沖擊是不可避免的。通訊及網(wǎng)絡(luò)受外部干擾的可能性大，外部環(huán)境是造成通訊外部設(shè)備故障的最大因素之一。系統(tǒng)總線的損壞主要由于現(xiàn)在PLC多為插件結(jié)構(gòu)，長期使用插拔模塊會(huì)造成局部印刷板或底板、接插件接口等處的總線損壞，在空氣溫度變化、濕度變化的影響下，總線的塑料老化、印刷線路的老化、接觸點(diǎn)的氧化等都是系統(tǒng)總線損耗的原因。所以在系統(tǒng)設(shè)計(jì)和處理系統(tǒng)故障的時(shí)候要考慮到空氣、塵埃、紫外線等因素對(duì)設(shè)備的破壞。目前PLC的主存儲(chǔ)器大多采用可擦寫ROM，其使用壽命除了主要與制作工藝相關(guān)外，還和底板的供電、CPU模塊工藝水平有關(guān)。而PLC的中央處理器目前都采用高性能的處理芯片，故障率已經(jīng)大大下降。對(duì)于PLC主機(jī)系統(tǒng)的故障的預(yù)防及處理主要是提高集中控制室的管理水平，加裝降溫措施，定期除塵，使PLC的外部環(huán)境符合其安裝運(yùn)行要求；同時(shí)在系統(tǒng)維修時(shí)，嚴(yán)格按照操作規(guī)程進(jìn)行操作，謹(jǐn)防人為的對(duì)主機(jī)系統(tǒng)造成損害。PLC最大的薄弱環(huán)節(jié)在I／O端口。PLC的技術(shù)優(yōu)勢(shì)在于其I／O端口，在主機(jī)系統(tǒng)的技術(shù)水平相差無幾的情況下，I／O模塊是體現(xiàn)PLC性能的關(guān)鍵部件，因此它也是PLC損壞中的突出環(huán)節(jié)。要減少I／O模塊的故障就要減少外部各種干擾對(duì)其影響，首先要按照其使用的要求進(jìn)行使用，不可隨意減少其外部保護(hù)設(shè)備，其次分析主要的干擾因素，對(duì)主要干擾源要進(jìn)行隔離或處理。第一類故障點(diǎn)(也是故障最多的地點(diǎn))在繼電器、接觸器。如該生產(chǎn)線PLC控制系統(tǒng)的日常維護(hù)中，電氣備件消耗量最大的為各類繼電器或空氣開關(guān)。主要原因除產(chǎn)品本身外，就是現(xiàn)場(chǎng)環(huán)境比較惡劣，接觸器觸點(diǎn)易打火或氧化，然后發(fā)熱變形直至不能使用。在該生產(chǎn)線上所有現(xiàn)場(chǎng)的控制箱都是選用密閉性較好的盤柜，其內(nèi)部元器件較其他采用敞開式盤柜內(nèi)元器件的使用壽命明顯要長。所以減少此類故障應(yīng)盡量選用高性能繼電器，改善元器件使用環(huán)境，減少更換的頻率，以減少其對(duì)系統(tǒng)運(yùn)行的影響。

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(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)起來也就簡單了。
