通常我們考慮將控制系統(tǒng)網(wǎng)絡(luò)化，主要將網(wǎng)絡(luò)化與現(xiàn)場(chǎng)總線聯(lián)系在一起。在控制領(lǐng)域較有影響的現(xiàn)場(chǎng)總線系統(tǒng)有：FF、LonWorks、Profibus、CAN、HART，以及RS485的總線網(wǎng)絡(luò)等?，F(xiàn)場(chǎng)總線基金會(huì)己經(jīng)制定的統(tǒng)一標(biāo)準(zhǔn)（（FF），其慢速總線標(biāo)準(zhǔn)Hl已得到通過成為國(guó)際標(biāo)準(zhǔn)，其高速總線標(biāo)準(zhǔn)H2還在制訂中。但是由于商業(yè)利潤(rùn)、技術(shù)壟斷等原因，現(xiàn)場(chǎng)總線產(chǎn)品仍然是百花齊放的局面，這對(duì)降低系統(tǒng)成本，擴(kuò)大應(yīng)用范圍產(chǎn)生不利影響。

以太網(wǎng)已經(jīng)得到廣泛應(yīng)用，主流產(chǎn)品的速度己經(jīng)達(dá)到100Mbps，千兆以太網(wǎng)也己經(jīng)投入使用，其網(wǎng)絡(luò)產(chǎn)品和軟件發(fā)展速度很快。以太網(wǎng)以成本低、組網(wǎng)方便、軟硬件豐富、可靠性高等特點(diǎn)得到了廣泛的認(rèn)可。

Internet飛速發(fā)展的主要原因在于以太網(wǎng)和TCP/IP協(xié)議的廣泛應(yīng)用，TCP/IP協(xié)議是極其靈活的，幾乎所有的網(wǎng)絡(luò)底層技術(shù)都可用于傳輸TCP/IP的通信。應(yīng)用TCP/IP的以太網(wǎng)已經(jīng)成為的分組交換局域網(wǎng)技術(shù)，同時(shí)也是開放性的網(wǎng)絡(luò)技術(shù)。

由此，我們考慮將Internet及其相關(guān)技術(shù)集成到現(xiàn)有控制系統(tǒng)中，利用Internet上開放的、并且己經(jīng)成熟的技術(shù)對(duì)現(xiàn)有的控制系統(tǒng)進(jìn)行升級(jí)改造，加快工業(yè)企業(yè)的信息一控制一體化進(jìn)程，不失為一種較為可行的問題解決方案

控制網(wǎng)絡(luò)的發(fā)展,其基本趨勢(shì)是逐漸趨向于開放性、透明的通訊協(xié)議。上述出現(xiàn)的問題,根本原因在于現(xiàn)場(chǎng)總線的開放性是有條件的、不徹底的。以太網(wǎng)具有傳輸速度高、低耗、易于安裝和兼容性好等方面的優(yōu)勢(shì),由于它支持幾乎所有流行的網(wǎng)絡(luò)協(xié)議,所以在商業(yè)系統(tǒng)中被廣泛采用。近些年來,隨著網(wǎng)絡(luò)技術(shù)的發(fā)展,以太網(wǎng)進(jìn)入了控制領(lǐng)域,形成了新型的以太網(wǎng)控制網(wǎng)絡(luò)技術(shù)。這主要是由于工業(yè)自動(dòng)化系統(tǒng)向分布化、智能化控制方面發(fā)展,開放的、透明的通訊協(xié)議是必然的要求?，F(xiàn)場(chǎng)總線由于種類繁多，互不兼容，尚不能滿足這一要求。而以太網(wǎng)的TCP/IP協(xié)議的開放性使得在工控領(lǐng)域通訊這一關(guān)鍵環(huán)節(jié)具有無可比擬的優(yōu)勢(shì)
