描述

GE IC697BEM731
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(shí),又總是先掃描梯形圖左邊的由各觸點(diǎn)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(diǎn)構(gòu)成的控制線路進(jìn)行邏輯運(yùn)算,然后根據(jù)邏輯運(yùn)算的結(jié)果,刷新該邏輯線圈在系統(tǒng)RAM存儲(chǔ)區(qū)中對(duì)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(duì)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(diǎn)在I/O映象區(qū)內(nèi)的狀態(tài)和數(shù)據(jù)不會(huì)發(fā)生變化,而其他輸出點(diǎn)和軟設(shè)備在I/O映象區(qū)或系統(tǒng)RAM存儲(chǔ)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(huì)對(duì)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(gè)掃描周期才能對(duì)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(diǎn)。即使用I/O指令的話,輸入過程影像寄存器的值不會(huì)被更新,程序直接從I/O模塊取值,輸出過程影像寄存器會(huì)被立即更新,這跟立即輸入有些區(qū)別。

PLC中的定時(shí)器(T)相當(dāng)于繼電器控制系統(tǒng)中的通電型時(shí)間繼電器。它可以提供無限對(duì)常開常閉延時(shí)觸點(diǎn)。定時(shí)器中有一個(gè)設(shè)定值寄存器(一個(gè)字長),一個(gè)當(dāng)前值寄存器(一個(gè)字長)和一個(gè)用來存儲(chǔ)其輸出觸點(diǎn)的映象寄存器(一個(gè)二進(jìn)制位),這三個(gè)量使用同一地址編號(hào)。但使用場合不一樣,意義也不同。
FX2N系列中定時(shí)器時(shí)可分為通用定時(shí)器、積算定時(shí)器二種。它們是通過對(duì)一定周期的時(shí)鐘脈沖的進(jìn)行累計(jì)而實(shí)現(xiàn)定時(shí)的,時(shí)鐘脈沖有周期為1ms、10ms、100ms三種,當(dāng)所計(jì)數(shù)達(dá)到設(shè)定值時(shí)觸點(diǎn)動(dòng)作。設(shè)定值可用常數(shù)K或數(shù)據(jù)寄存器D的內(nèi)容來設(shè)置。

15天包退換 一年質(zhì)保 大量現(xiàn)貨? 國內(nèi)實(shí)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(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。
