PLC程序的內(nèi)容

? ??PLC應(yīng)用程序應(yīng)最大限度地滿足被控對象的控制要求,在構(gòu)思程序主體的框架后,要以它為主線,逐一編寫實(shí)現(xiàn)各控制功能或各子任務(wù)的程序。經(jīng)過不斷他調(diào)整和完善。使程序能完成所要求的控制功能。另外,PLC應(yīng)用程序通常還應(yīng)包括以下幾個方面的內(nèi)容:
? ? (1)初始化程序在PLC上電后,一般都要做一些初始化的操作。其作用是為啟動作必要的準(zhǔn)備,并避免系統(tǒng)發(fā)生誤動作。初始化程序的主要內(nèi)容為:將某些數(shù)據(jù)區(qū)、計數(shù)器進(jìn)行清零;使某些數(shù)據(jù)區(qū)恢復(fù)所需數(shù)據(jù);對某些輸出量置位或復(fù)位;顯示某些初始狀態(tài)等等。
? ? (2)檢測、故障診斷、顯示程序應(yīng)用程序一般都設(shè)有檢測、故障診斷和顯示程序等內(nèi)容。這些內(nèi)容可以在程序設(shè)計基本完成時再進(jìn)行添加。它們也可以是相對獨(dú)立的程序段。
? ? (3)保護(hù)、連鎖程序各種應(yīng)用程序中,保護(hù)和連鎖是不可缺少的部分。它可以杜絕由于非法操作而引起的控制邏輯混亂,保證系統(tǒng)的運(yùn)行更安全、可靠。因此要認(rèn)真考慮保護(hù)和連鎖的問題。通常在PLC外部也要設(shè)置連鎖和保護(hù)措施。

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,福克斯波羅、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”(不管能不能看懂,先了解個大概,以便學(xué)習(xí)編程時查找);
2、由位控邏輯入手,逐漸增加定時、計數(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)會一種至于其它的學(xué)習(xí)起來也就簡單了。
