隨著現(xiàn)場總線技術(shù)的出現(xiàn)和成熟，促使了控制系統(tǒng)由集散控制系統(tǒng)（DCS）向現(xiàn)場總線控制系統(tǒng)（FCS）的過渡。在一般的FCS系統(tǒng)中，遵循一定現(xiàn)場總線協(xié)議的現(xiàn)場儀表可以組成控制回路，使控制站的部分控制功能下移分散到各個(gè)現(xiàn)場儀表中。從而減輕了控制站負(fù)擔(dān)，使得控制站可以專職于執(zhí)行復(fù)雜的高層次的控制算法。對于簡單的控制應(yīng)用，甚至可以把控制站取消，在控制站的位置代之以起連接現(xiàn)場總線作用的網(wǎng)橋和集線器，操作站直接與現(xiàn)場儀表相連，構(gòu)成分布式控制系統(tǒng)。分布式的FCS系統(tǒng)比DCS系統(tǒng)更好地體現(xiàn)了“信息集中，控制分散”的思想。與傳統(tǒng)的DCS相比，F(xiàn)CS有其自身的特點(diǎn)。FCS系統(tǒng)具有高度的分散性，它可以由現(xiàn)場設(shè)備組成自治的控制回路。現(xiàn)場儀表或設(shè)備具有高度的智能化與功能自主性，可完成控制的基本功能，并可以隨時(shí)診斷設(shè)備的運(yùn)行情況。另外，F(xiàn)CS的結(jié)構(gòu)比DCS簡化。有的FCS系統(tǒng)省略了DCS中控制站這一層，操作站直接與現(xiàn)場儀表相連。這些使FCS的可靠性得到提高
