如何抉擇PLC和DCS系統(tǒng)
在可編程邏輯控制器(PLC)和分散式控制系統(tǒng)(DCS)之間如何抉擇,要具體情況具體分析,因為應用場合不同,對控制系統(tǒng)的要求也各不相同。
控制系統(tǒng)平臺,對自動化系統(tǒng)滿足優(yōu)化生產(chǎn)、維持可用性和獲取數(shù)據(jù)等需求的方式,會有一定的影響。在選擇控制系統(tǒng)方面缺乏遠見,也可能會影響未來的擴展、流程優(yōu)化、用戶滿意度和公司利潤。
除了一些基本準則之外(比如如何控制過程),設計團隊還必須考慮安裝、可擴展性、維護、保養(yǎng)等方面的各種因素。
目前,雖然對小設備來講,PLC系統(tǒng)可能是最劃算的,但DCS系統(tǒng)則提供了更具經(jīng)濟性的可擴展能力,更可能獲得較高的初始投資回報。
PLC是一種工業(yè)計算機,用于控制生產(chǎn)制造過程,如機器人、高速包裝、裝瓶和運動控制等。在過去20年里,PLC增添了更多的功能,為小型工廠和裝置創(chuàng)造了更多的效益。PLC通常是單機系統(tǒng)運行,但也可以與其它系統(tǒng)集成,經(jīng)由通信來實現(xiàn)彼此之間的連接。由于每個PLC都有自己的數(shù)據(jù)庫,因此集成需要控制器之間某種程度的映射。這使PLC特別適用于那些對擴展沒有太大需求的小型應用程序。DCS系統(tǒng)則將控制器分散在自動化系統(tǒng)中,并提供通用的接口、先進的控制、系統(tǒng)級數(shù)據(jù)庫以及易于共享的信息。傳統(tǒng)上,DCS主要應用于過程工藝和比較大的工廠,在整個工廠的生命周期中,大型系統(tǒng)應用程序更容易維護。

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、類型轉換;
4、量程轉換、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、跳轉等程序控制(盡量避免跳轉,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。
