描述

2711P-T7C21D8S

輸入采樣階段:首先掃描所有輸入端子,并將各輸入狀態(tài)存入相對應(yīng)的輸入映像寄存器中,輸入映像寄存器被刷新。在輸入采樣階段,可編程邏輯控制器以掃描方式依次地讀入所有輸入狀態(tài)和數(shù)據(jù),并將它們存入I/O映象區(qū)中的相應(yīng)的單元內(nèi)。輸入采樣結(jié)束后,轉(zhuǎn)入用戶程序執(zhí)行和輸出刷新階段。在這兩個階段中,即使輸入狀態(tài)和數(shù)據(jù)發(fā)生變化,I/O映象區(qū)中的相應(yīng)單元的狀態(tài)和數(shù)據(jù)也不會改變。因此,如果輸入是脈沖信號,則該脈沖信號的寬度必須大于一個掃描周期,才能保證在任何情況下,該輸入均能被讀入。接著進入程序執(zhí)行階段。
程序執(zhí)行階段:根據(jù)PLC梯形圖程序掃描原則,一般按從左到右,從上到下的原則順序執(zhí)行程序。在用戶程序執(zhí)行階段,可編程邏輯控制器總是按由上而下的順序依次地掃描用戶程序(梯形圖)。在掃描每一條梯形圖時,又總是先掃描梯形圖左邊的由各觸點構(gòu)成的控制線路,并按先左后右、先上后下的順序?qū)τ捎|點構(gòu)成的控制線路進行邏輯運算,然后根據(jù)邏輯運算的結(jié)果,刷新該邏輯線圈在系統(tǒng)RAM存儲區(qū)中對應(yīng)位的狀態(tài);或者刷新該輸出線圈在I/O映象區(qū)中對應(yīng)位的狀態(tài);或者確定是否要執(zhí)行該梯形圖所規(guī)定的特殊功能指令。即,在用戶程序執(zhí)行過程中,只有輸入點在I/O映象區(qū)內(nèi)的狀態(tài)和數(shù)據(jù)不會發(fā)生變化,而其他輸出點和軟設(shè)備在I/O映象區(qū)或系統(tǒng)RAM存儲區(qū)內(nèi)的狀態(tài)和數(shù)據(jù)都有可能發(fā)生變化,而且排在上面的梯形圖,其程序執(zhí)行結(jié)果會對排在下面的凡是用到這些線圈或數(shù)據(jù)的梯形圖起作用;相反,排在下面的梯形圖,其被刷新的邏輯線圈的狀態(tài)或數(shù)據(jù)只能到下一個掃描周期才能對排在其上面的程序起作用。在程序執(zhí)行的過程中如果使用立即I/O指令則可以直接存取I/O點。即使用I/O指令的話,輸入過程影像寄存器的值不會被更新,程序直接從I/O模塊取值,輸出過程影像寄存器會被立即更新,這跟立即輸入有些區(qū)別。
輸出刷新階段:在所有指令執(zhí)行完畢后,元件映像器中所有輸出繼電器的狀態(tài)在輸出刷新階段轉(zhuǎn)存至輸出鎖存器中,通過一定的方式輸出,最后經(jīng)過輸出端子驅(qū)動外部負載。當掃描用戶程序結(jié)束后,可編程邏輯控制器就進入輸出刷新階段。在此期間,CPU按照I/O映象區(qū)內(nèi)對應(yīng)的狀態(tài)和數(shù)據(jù)刷新所有的輸出鎖存電路,再經(jīng)輸出電路驅(qū)動相應(yīng)的外設(shè)。這時,才是PLC的真正輸出

15天包退換 一年質(zhì)保 大量現(xiàn)貨? 國內(nèi)實力庫存商家


選擇深圳長欣,選擇放心,售后無憂大量現(xiàn)貨,當天順豐發(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,機器人系統(tǒng)配件,大型伺服系統(tǒng)備件。

先介紹幾點經(jīng)驗。
1、先通讀一遍“系統(tǒng)手冊”(不管能不能看懂,先了解個大概,以便學習編程時查找);
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、進而練習整數(shù)運算、實數(shù)運算、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證,比如變頻器+電機+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,學會一種至于其它的學習起來也就簡單了。
