P-HA-RPS-32000000

正確性
? ? PLC的程序一定要正確，并要經(jīng)過(guò)實(shí)際工作驗(yàn)證，證明其能夠正確工作。這是對(duì)PLC程序的最根本的要求，若這一點(diǎn)做不到，其它的再好也沒(méi)有用。
? ? 要使程序正確，一定要準(zhǔn)確的使用指令，正確的使用內(nèi)部器件。準(zhǔn)確的使用指令與準(zhǔn)確理解指令相聯(lián)系，為此對(duì)指令含義和使用條件一定要弄清楚。必要時(shí)，可編些小程序?qū)σ恍┎磺宄闹噶钭餍y(cè)試。
? ? 同一指令，由于PLC的出廠批次不同或是PLC的系列型號(hào)的不同，一些指令細(xì)節(jié)有可能不一樣，應(yīng)仔細(xì)查閱編程手冊(cè)。
? ? 內(nèi)部器件正確使用也是重要的。如有的PLC有掉電保護(hù)，有的PLC沒(méi)有。一定要做到該掉電保護(hù)的一定要用掉電保護(hù)的器件，反之則不能用。
? ? 總之，要準(zhǔn)確的使用指令，正確使用內(nèi)部器件，使所編的程序能正確要作，這是對(duì)PLC程序最根本的要求。
? ? 5、可靠性
? ? 程序不僅要正確，還要可靠?？煽糠从持鳳LC程序的穩(wěn)定性，這也是對(duì)PLC程序的基本要求。
? ? 有的PLC程序，在正常的工作條件下或合法操作時(shí)能正確工作，而出現(xiàn)非正常工作條件（如臨時(shí)停電，又很快再通電）或進(jìn)行非法操作（如一些按鈕不按順序按，或同時(shí)按若干按鈕）后，程序就不能正常工作了。這種程序，就不大可靠，或說(shuō)不穩(wěn)定，就是不好的程序。
? ? 好的PLC程序?qū)Ψ钦９ぷ鳁l件出現(xiàn)，能予以識(shí)別，并能使其與正常條件銜接，可使程序適應(yīng)于多種情況。好的PLC程序?qū)Ψ欠ú僮髂苡枰跃芙^，且不留下“痕跡”。只接受合法操作。
? ? 聯(lián)鎖是拒絕非法操作常用的手段，繼電電路常用這個(gè)方法，PLC也可繼承這個(gè)方法。

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。
