基于OPC過(guò)程控制系統(tǒng)結(jié)構(gòu)采用客戶(hù)/服務(wù)器模式，通常把符合OPC規(guī)范的設(shè)備驅(qū)動(dòng)程序稱(chēng)為OPC服務(wù)器，而將符合OPC規(guī)范的應(yīng)用軟件統(tǒng)稱(chēng)為OPC客戶(hù)。服務(wù)器充當(dāng)客戶(hù)與硬件設(shè)備之間的橋梁，客戶(hù)對(duì)硬件設(shè)備的數(shù)據(jù)讀寫(xiě)操作由服務(wù)器代理完成，客戶(hù)不需要同硬件設(shè)備直接打交道，或者說(shuō)客戶(hù)是獨(dú)立于設(shè)備的（即不管現(xiàn)場(chǎng)設(shè)備以何種形式存在，客戶(hù)都以統(tǒng)一的方式去訪問(wèn)）。在客戶(hù)端和服務(wù)器端各自定義了統(tǒng)一的標(biāo)準(zhǔn)“接口”，接口具有不變特性，OPC所提供的接口標(biāo)準(zhǔn)事實(shí)上是一種“軟件接口標(biāo)準(zhǔn)”或“軟件總線”，它明確定義了客戶(hù)同服務(wù)器之間的通信機(jī)制，是連接客戶(hù)同服務(wù)器的橋梁和紐帶。這樣，我們可以自由選擇最符合我們實(shí)際要求的軟、硬件產(chǎn)品，然后將它們像“搭積木”一樣組合在一起進(jìn)行無(wú)縫地工作，這一切都來(lái)源于OPC所提供的強(qiáng)大互操作性的特點(diǎn)，對(duì)此我們可以作一個(gè)形象的比喻：盡管家用電器的種類(lèi)繁多，但它們的電源插頭與插座卻是統(tǒng)一的�？梢赃@樣說(shuō)，統(tǒng)一的標(biāo)準(zhǔn)接口是OPC的實(shí)質(zhì)和靈魂。
類(lèi)似于工業(yè)組態(tài)軟件中的相關(guān)概念，OPC規(guī)范主要定義了數(shù)據(jù)訪問(wèn)規(guī)范、報(bào)警和事件處理規(guī)范及歷史數(shù)據(jù)訪問(wèn)規(guī)范三部分，對(duì)應(yīng)于每種規(guī)范可以實(shí)現(xiàn)相應(yīng)的OPC服務(wù)器。OPC數(shù)據(jù)訪問(wèn)服務(wù)器在結(jié)構(gòu)上由服務(wù)器（Server）、組（Group）和項(xiàng)（Item）三級(jí)對(duì)象組成。在邏輯關(guān)系上，上一級(jí)對(duì)象是下一級(jí)對(duì)象的父對(duì)象，下一級(jí)對(duì)象則是上一級(jí)對(duì)象的子對(duì)象，OPC數(shù)據(jù)訪問(wèn)服務(wù)器正是通過(guò)這種“集合”的概念來(lái)組織和管理其內(nèi)部結(jié)構(gòu)的。項(xiàng)對(duì)象作為結(jié)構(gòu)層次中最基本的單元直接對(duì)應(yīng)著物理硬件設(shè)備的某個(gè)具體數(shù)據(jù)單元，項(xiàng)對(duì)象作為物理數(shù)據(jù)的存儲(chǔ)載體，主要包含數(shù)據(jù)值（當(dāng)前設(shè)備單元中的數(shù)據(jù)）、時(shí)間標(biāo)簽（當(dāng)前采集到的數(shù)據(jù)時(shí)間定位）和品質(zhì)信息（當(dāng)前采集到的數(shù)據(jù)可靠程度）等信息。
客戶(hù)對(duì)硬件設(shè)備的數(shù)據(jù)讀寫(xiě)操作分為同步和異步兩種方式。同步方式適合于發(fā)送、接收數(shù)據(jù)量較少的場(chǎng)合；相比同步方式，異步方式占用較少的資源，效率更高，適合大數(shù)據(jù)量的場(chǎng)合，在實(shí)際中的應(yīng)用也更為廣泛。在沒(méi)有開(kāi)發(fā)出OPC標(biāo)準(zhǔn)之前，異步方式的存取是不可能的，會(huì)導(dǎo)致存取沖突的發(fā)生。
