描述

GE IC693PWR321

PLC網(wǎng)絡(luò)是由幾級子網(wǎng)復(fù)合而成,各級子網(wǎng)的通信過程是由通信協(xié)議決定的,而通信方式是通信協(xié)議最核心的內(nèi)容。通信方式包括存取控制方式和數(shù)據(jù)傳送方式。所謂存取控制(也稱訪問控制)方式是指如何獲得共享通信介質(zhì)使用權(quán)的問題,而數(shù)據(jù)傳送方式是指一個站取得了通信介質(zhì)使用權(quán)后如何傳送數(shù)據(jù)的問題。

周期I/O通信方式常用于PLC的遠(yuǎn)程I/O鏈路中。遠(yuǎn)程I/O鏈路按主從方式工作,PLC遠(yuǎn)程I/O主單元為主站,其它遠(yuǎn)程I/O單元皆為從站。在主站中設(shè)立一個“遠(yuǎn)程I/O緩沖區(qū)”,采用信箱結(jié)構(gòu),劃分為幾個分箱與每個從站—一對應(yīng),每個分箱再分為兩格,一格管發(fā)送,一格管接收。主站中通信處理器采用周期掃描方式,按順序與各從站交換數(shù)據(jù),把與其對應(yīng)的分箱中發(fā)送分格的數(shù)據(jù)送給從站,從從站中讀取數(shù)據(jù)放入與其對應(yīng)的分箱的接收分格中。這樣周而復(fù)始,使主站中的“遠(yuǎn)程I/O緩沖區(qū)”得到周期性的刷新。
在主站中PLC的CPU單元負(fù)責(zé)用戶程序的掃描,它按照循環(huán)掃描方式進(jìn)行處理,每個周期都有一段時間集中進(jìn)行I/O處理,這時它對本地I/O單元及遠(yuǎn)程I/O緩沖區(qū)進(jìn)行讀寫操作。PLC的CPU單元對用戶程序的周期性循環(huán)掃描,與PLC通信處理器對各遠(yuǎn)程I/O單元的周期性掃描是異步進(jìn)行的。盡管PLC的CPU單元沒有直接對遠(yuǎn)程I/O單元進(jìn)行操作,但是由于遠(yuǎn)程I/O緩沖區(qū)獲得周期性刷新,PLC的CPU單元對遠(yuǎn)程I/O緩沖區(qū)的讀寫操作,就相當(dāng)于直接訪問了遠(yuǎn)程I/O單元。這種通信方式簡單、方便,但要占用PLC的I/O區(qū),因此只適用于少量數(shù)據(jù)的通信。??雖然不同品牌PLC產(chǎn)品相差無幾,但并不代表用不同的品牌的東西可以掉以輕心。相對于某些由三菱PLC應(yīng)用轉(zhuǎn)到西門子PLC應(yīng)用中的用戶來說,在接觸及使用的初期,更加應(yīng)該從使用、保養(yǎng)、儲存等最基礎(chǔ)的地方入手,才可以把應(yīng)用技巧發(fā)揮到最極致。下面是關(guān)于如何保養(yǎng)西門子PLC的相關(guān)事項(xiàng)。

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”(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(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。
