DCS已廣泛應(yīng)用于火電站主設(shè)備的控制系統(tǒng)，現(xiàn)場(chǎng)總線的應(yīng)用要借助于DCS。這樣既豐富了DCS的功能，又推動(dòng)了現(xiàn)場(chǎng)總線和FCS的發(fā)展?，F(xiàn)場(chǎng)總線和DCS的集成有兩種方式：現(xiàn)場(chǎng)總線與DCS的I／O總線集成；現(xiàn)場(chǎng)總線與DCS網(wǎng)絡(luò)的集成。前者是現(xiàn)場(chǎng)儀表或現(xiàn)場(chǎng)設(shè)備通過(guò)現(xiàn)場(chǎng)總線與現(xiàn)場(chǎng)總線接口單元通信，現(xiàn)場(chǎng)總線接口單元再通過(guò)I／0總線與DCS處理器通信。后者是現(xiàn)場(chǎng)儀表或現(xiàn)場(chǎng)設(shè)備通過(guò)現(xiàn)場(chǎng)總線與現(xiàn)場(chǎng)總線服務(wù)器通信，現(xiàn)場(chǎng)總線服務(wù)器直接掛在DCS網(wǎng)絡(luò)上。 PLC已廣泛應(yīng)用于火電站輔助設(shè)備的控制系統(tǒng)，現(xiàn)場(chǎng)總線的應(yīng)用也要借助于PLC。現(xiàn)場(chǎng)總線中，象Contr01．Net、ProfiBus等本身就是PLC的主要供貨商支持的，而且這些現(xiàn)場(chǎng)總線技術(shù)和產(chǎn)品已集成到PLC系統(tǒng)中，成為PLC系統(tǒng)中的一部分或者成為PLC系統(tǒng)的延伸部分。以ControlNet為例，ContmlNet最早由美國(guó)Rockwell Automation于1995年10月提出，它是一種高速、高確定性和可重復(fù)性的網(wǎng)絡(luò)，特別適用于對(duì)時(shí)間有苛刻要求的復(fù)雜應(yīng)用場(chǎng)合的信息傳輸。在火電站中應(yīng)用十分廣泛的PLC系統(tǒng)之一ControlLogix系統(tǒng)就是利用ContmlNet構(gòu)筑分布式I／O網(wǎng)絡(luò)系統(tǒng)的。作為PLC系統(tǒng)的延伸，ControlNet還被用作廠級(jí)控制網(wǎng)連接整個(gè)火電站的輔助系統(tǒng)，包括除灰除渣系統(tǒng)、輸煤系統(tǒng)、水處理系統(tǒng)等，通過(guò)ControlNet可以實(shí)現(xiàn)全廠輔助系統(tǒng)的集中監(jiān)控和數(shù)據(jù)共享。 現(xiàn)場(chǎng)總線在網(wǎng)絡(luò)方面的特點(diǎn)使其與信息網(wǎng)絡(luò)的集成變得十分自然。工業(yè)以太網(wǎng)便是一個(gè)典型例子。工業(yè)以太網(wǎng)雖不屬于現(xiàn)場(chǎng)總線的12種國(guó)際標(biāo)準(zhǔn)，但隨著其迅猛發(fā)展，工業(yè)以太網(wǎng)已成為事實(shí)上的工業(yè)標(biāo)準(zhǔn)。隨著以太網(wǎng)的通信速率的不斷提高和全雙工交換式以太網(wǎng)的誕生，以太網(wǎng)的非確定性問(wèn)題已經(jīng)解決。目前火電站的廠級(jí)信息網(wǎng)絡(luò)系統(tǒng)幾乎都是采用以太網(wǎng)，通過(guò)工業(yè)以太網(wǎng)可實(shí)現(xiàn)現(xiàn)場(chǎng)總線與信息網(wǎng)絡(luò)的集成。 目前在火電站中，壓力變送器等儀表一般都選用智能型、支持HART通信協(xié)議的。但這些儀表并沒(méi)有構(gòu)成HART通信網(wǎng)絡(luò)，HART通信僅用于通過(guò)手操器來(lái)對(duì)儀表進(jìn)行設(shè)定。這一方面說(shuō)明了火電站在智能儀表方面已經(jīng)為現(xiàn)場(chǎng)總線技術(shù)的應(yīng)用提供了一些條件，另一方面也說(shuō)明了現(xiàn)場(chǎng)總線在火電站的應(yīng)用確實(shí)具有一定的阻力，這種阻力主要的并不在于投資方面。
