描述

1C31189G01

三菱FX系列PLC的定時器分為無掉電保持能力的通用定時器和有掉電保持能力的積算定時器。按計數(shù)的時鐘脈沖可分為1ms、10ms、100ms的定時器。定時器的工作可描述為:當(dāng)定時器的定時條件滿足,線圈被驅(qū)動后,定時器開始計時,計時時間到,其觸點動作。PLC是按照循環(huán)掃描方式丁作的,一個循環(huán)掃描周期可分為內(nèi)部處理、通信服務(wù)、輸入刷新、程序執(zhí)行和輸出刷新5個階段。由于這5個階段在PLC處于RUN運行模式時是分時執(zhí)行的。因此這種掃描方式會對PIC的定時精度造成一定的影響。1定時的精度定時的精度與程序的安排有關(guān),也與定時輸入信號(定時條件)和定時器定時完成的確切時間有關(guān)。下面就極限情況來分析定時器的精度。1.1定時器的觸點在線圈之后在此我們假設(shè)定時器的輸入(對應(yīng)于圖1中)恰在PLC剛完成輸入刷新后變?yōu)镺N,我們知道,PLC在1個掃描周期內(nèi),輸入只被掃描1次,因此在這個掃描周期程序執(zhí)行階段定時器并不能工作,只有等到下個掃描周期。這樣便產(chǎn)生了1個掃描周期的誤差。我們再次假設(shè),定時器定時完成的確切時間在剛執(zhí)行完梯形圖定時器的線圈指令,即執(zhí)行完OUTTo指令后。

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(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(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。
