??通過（PLC網(wǎng)絡(luò)的拓?fù)浣Y(jié)構(gòu)）典型PLC網(wǎng)絡(luò)的介紹，可以看出PLC網(wǎng)絡(luò)各級子網(wǎng)通信協(xié)議配置的規(guī)律如下：

? ? 1）PLC網(wǎng)絡(luò)通常采用3級或4級子網(wǎng)構(gòu)成的復(fù)合型拓?fù)浣Y(jié)構(gòu)，各級子網(wǎng)中配置不同的通信協(xié)議，以適應(yīng)不同的通信要求。
? ? 2）在PLC網(wǎng)絡(luò)中配置的通信協(xié)議分兩類：一類是通用協(xié)議，一類是公司專用協(xié)議。
? ? 3）在PLC網(wǎng)絡(luò)的高層子網(wǎng)中配置的通用協(xié)議主要有兩種，一種是MAP規(guī)約（全MAP3．0），一種是Ethernet協(xié)議，這反映PLC網(wǎng)絡(luò)標(biāo)準(zhǔn)化與通用化的趨勢。PLC網(wǎng)的互聯(lián)，PLC網(wǎng)與其它局域網(wǎng)的互聯(lián)將通過高層進(jìn)行。
? ? 4）在PLC網(wǎng)絡(luò)的低層子網(wǎng)及中間層子網(wǎng)采用公司專用協(xié)議。其最底層由于傳遞過程數(shù)據(jù)及控制命令，這種信息很短，對實(shí)時性要求又較高，常采用周期I/O方式通信；中間層負(fù)責(zé)傳送監(jiān)控信息，信息長度居于過程數(shù)據(jù)及管理信息之間，對實(shí)時性要求也比較高，其通信協(xié)議常用令牌方式控制通信，也有采用主從方式控制通信的。
? ? 5）PC加入不同級別的子網(wǎng)，必須按所連入的子網(wǎng)配置通信模板，并按該級子網(wǎng)
? ? 配置的通信協(xié)議編制用戶程序，一般在PLC中不需編制程序。對于協(xié)議比較復(fù)雜的干網(wǎng)，可購置廠家供應(yīng)的通信軟件裝入PC中，將使用戶通信程序編制變得比較簡單方便。
? ? 6）PLC網(wǎng)絡(luò)低層子網(wǎng)對實(shí)時性要求較高，其采用的協(xié)議大多為塌縮結(jié)構(gòu)，只有物理層、鏈路層及應(yīng)用層；而高層子網(wǎng)傳送管理信息，與普通網(wǎng)絡(luò)性質(zhì)接近，又要考慮異種網(wǎng)互聯(lián)，因此高層子網(wǎng)的通信協(xié)議大多為7層。

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。
