    當(dāng)前，在所有過程控制領(lǐng)域，大的發(fā)展趨勢(shì)之一就是Ethernet技術(shù)的擴(kuò)展。PLC也例外，現(xiàn)在，越來越多的PLC供應(yīng)商開始提供Ethernet接口部件。在近的幾年間，我們已經(jīng)看到，發(fā)展比現(xiàn)有普通小快靈PLC更加強(qiáng)大的PLC是種趨勢(shì)。Ethernet將會(huì)成為PLC的通信標(biāo)準(zhǔn)嗎？也許終結(jié)果是這樣的，但現(xiàn)在還為時(shí)尚早。對(duì)于在PLC上提供Ethernet接口將能夠解決所有通信問題，人們普遍存在著誤解。Ethernet僅僅定義了OSI參考模型底部的幾層協(xié)議標(biāo)準(zhǔn)，如果上層協(xié)議相互之間不能兼容，那么仍然不可能進(jìn)行相互之間的通信處理。打個(gè)比方，這如同一個(gè)不懂英語的中國(guó)人與一個(gè)不懂漢語的美國(guó)人之間是不能夠通過電話進(jìn)行對(duì)話一樣。因此，協(xié)議就是設(shè)備之間相互通信的語言。

    另一方面，前進(jìn)的步伐已經(jīng)邁出，我們只有迎著困難而上，為了將Ethernet技術(shù)應(yīng)用到工廠底層的現(xiàn)場(chǎng)過程控制設(shè)備中去，ODVA協(xié)會(huì)為此建立了一套性標(biāo)準(zhǔn)技術(shù)規(guī)范，即Ethernet/IP標(biāo)準(zhǔn)，以便能夠解決在實(shí)際工作中所遇到的困難。
