七十年代以前，控制系統(tǒng)中采用模擬量對(duì)傳輸及控制信號(hào)進(jìn)行轉(zhuǎn)換、傳遞，其精度差、受干擾信號(hào)影響大，因而整個(gè)控制系統(tǒng)的控制效果及系統(tǒng)穩(wěn)定性都很差。七十年代末，隨著大規(guī)模集成電路的出現(xiàn)，微處理器技術(shù)得到很大發(fā)展。微處理器功能強(qiáng)、體積小、可靠性高、通過(guò)適當(dāng)?shù)慕涌陔娐酚糜诳刂葡到y(tǒng)，控制效果得到提高；但是盡管如此，還是屬于集中式控制系統(tǒng)。隨著過(guò)程控制技術(shù)、自動(dòng)化儀表技術(shù)和計(jì)算機(jī)網(wǎng)絡(luò)技術(shù)的成熟和發(fā)展，控制領(lǐng)域又發(fā)生了一次技術(shù)變革。這次變革使傳統(tǒng)的控制系統(tǒng)（如集散控制系統(tǒng)）無(wú)論在結(jié)構(gòu)上還是在性能上都發(fā)生了巨大的飛躍，這次變革的基礎(chǔ)就是現(xiàn)場(chǎng)總線技術(shù)的產(chǎn)生。

現(xiàn)場(chǎng)總線是連接現(xiàn)場(chǎng)智能設(shè)備和自動(dòng)化控制設(shè)備的雙向串行、數(shù)字式、多節(jié)點(diǎn)通信網(wǎng)絡(luò)，它也被稱為現(xiàn)場(chǎng)底層設(shè)備控制網(wǎng)絡(luò)（INFRANET）。80年代以來(lái)，各種現(xiàn)場(chǎng)總線技術(shù)開(kāi)始出現(xiàn)，人們要求對(duì)傳統(tǒng)的模擬儀表和控制系統(tǒng)變革的呼聲也越來(lái)越高，從而使現(xiàn)場(chǎng)總線成為一次世界性的技術(shù)變革浪潮。美國(guó)儀表協(xié)會(huì)(ISA)于1984年開(kāi)始制訂現(xiàn)場(chǎng)總線標(biāo)準(zhǔn)，在歐洲有德國(guó)的PROFIBUS和法國(guó)的FIP等，各種現(xiàn)場(chǎng)總線標(biāo)準(zhǔn)陸續(xù)形成。其中主要的有：基金會(huì)現(xiàn)場(chǎng)總線FF（Foundation Fieldbus）、控制局域網(wǎng)絡(luò)CAN（Controller Area Network）、局部操作網(wǎng)絡(luò)LonWorks（Local Operating Network）、過(guò)程現(xiàn)場(chǎng)總線PROFIBUS（Process Field Bus）和HART協(xié)議(Highway Addressable Remote Transducer)等。但是，總線標(biāo)準(zhǔn)的制定工作并非一帆風(fēng)順，由于行業(yè)與地域發(fā)展等歷史原因，加上各公司和企業(yè)集團(tuán)受自身利益的驅(qū)使，致使現(xiàn)場(chǎng)總線的國(guó)際化標(biāo)準(zhǔn)工作進(jìn)展緩慢。但是不論如何，制定單一的開(kāi)放國(guó)際現(xiàn)場(chǎng)總線標(biāo)準(zhǔn)是發(fā)展的必然。
