dcs的發(fā)展歷程
　　上世紀60年代以后，隨著生產(chǎn)工程的大型化和復(fù)雜化，誕生了計算機集中監(jiān)視和控制的集中控制系統(tǒng)。集中控制方便了監(jiān)視、操作和管理，同樣也使危險性高度集中，系統(tǒng)一旦故障，對裝置造成的影響和危險性都是非常大的。隨著微處理機的誕生，為新型控制系統(tǒng)的開放創(chuàng)造了無比優(yōu)越的條件。1975年，隨著計算機、通訊、控制和crt 4c技術(shù)的不斷發(fā)展和完善，美國honeywell首次向全球推出了分散控制系統(tǒng)tdc-2000，從第一套dcs誕生至今，dcs系統(tǒng)已經(jīng)經(jīng)歷了3個發(fā)展階段。
　　1975至1980年為初創(chuàng)階段。由于軟硬件技術(shù)的限制，此時的dcs系統(tǒng)性能還不十分完善，硬件結(jié)構(gòu)還不十分成熟。
　　1981至1987年為第2個階段。這一時期容錯、冗余技術(shù)已經(jīng)成熟使用，系統(tǒng)可靠性很高，性能十分優(yōu)越，各種控制功能十分豐富。在該階段dcs從單純的工業(yè)過程自動化控制向生產(chǎn)管理自動化發(fā)展。這一代的dcs主要將lan（local area network）技術(shù)引入，使dcs的網(wǎng)絡(luò)功能大大加強。
　　1987至今為第3個發(fā)展階段。各廠家采用國際標(biāo)準化組織（iso）開放系統(tǒng)互連（osi）結(jié)構(gòu)基礎(chǔ)上產(chǎn)生制造自動化協(xié)議（map）標(biāo)準來解決不同機型的互連問題。 dcs系統(tǒng)在硬件上使用了更先進的cpu及冗余技術(shù)，存儲容量及通訊速度大幅度提高，軟件上采用通用操作系統(tǒng)。在該階段dcs將控制、監(jiān)督和管理調(diào)度有機結(jié)合起來，實現(xiàn)了各種生產(chǎn)經(jīng)營信息的自動化管理。

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，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+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(xué)會一種至于其它的學(xué)習(xí)起來也就簡單了。
