描述

1746-NT8

系統(tǒng)采用RS-485進行網(wǎng)絡通訊,RS-485是一般工業(yè)控制所經(jīng)常采用的網(wǎng)絡通訊方式。它具有能夠?qū)崿F(xiàn)多機通訊(RS-485驅(qū)動器最多可接32個從站),通訊距離長,抗干擾能力強等特點。臺達DVP32ES00R主機具有RS-485通訊口,而臺達VFD變頻器也都有RS-485通訊口,并且提供了專用驅(qū)動指令。我們以PLC為主機,兩個變頻器為從機組成RS-485控制網(wǎng)絡。每個從站被賦與唯一的本機地址。通訊采用主機輪詢,從機應答的通訊方式,主機發(fā)出的信息可以被各從機接收,從機只能發(fā)出應答信息,從機間不能通信。從機接收到數(shù)據(jù)后,判斷地址是否和本機地址相同,若相同則對數(shù)據(jù)進行處理后應答,若不同則不予理睬。通過通訊主要是控制給棉電機和引紗電機的起停和工作頻率的修改,工作頻率初值是PLC根據(jù)設定的細紗號數(shù)和棉條號數(shù)計算得出。在機器運轉(zhuǎn)中,通過速度傳感器檢測,PLC進行計算比較,微調(diào)工作頻率,使機器運轉(zhuǎn)精度提高。其中需要注意的是在使用通訊進行控制變頻器的起停一定注意程序的邏輯順序,不然將會引起動作的混亂而不能達到預期的效果。

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。
