現(xiàn)場(chǎng)總線技術(shù)確實(shí)改變了傳統(tǒng)總線控制思維，常規(guī)的總線控制都是由一個(gè)主控CPU通過總線把子站數(shù)據(jù)拿過來進(jìn)行計(jì)算，然后根據(jù)結(jié)果再通過總線把控制要求下發(fā)給另一子站，這樣其實(shí)就是浪費(fèi)總線帶寬的資源，通過現(xiàn)場(chǎng)總線技術(shù)，可以把控制分散到各個(gè)子站，而每個(gè)子站有數(shù)據(jù)采集的終端和執(zhí)行者，這樣可以有效地減輕中央CPU的負(fù)擔(dān)，并且改變常規(guī)的控制模式。（今天的轉(zhuǎn)發(fā)暗號(hào)是：億維，專注核心控制）以前很多人都說現(xiàn)場(chǎng)總線可以節(jié)省大量布線成本，其實(shí)線纜成本是有一些但絕不是現(xiàn)場(chǎng)總線技術(shù)為之存在的理由，它是一種改變常規(guī)控制的革新式技術(shù)，它把控制的核心通過總線技術(shù)下放到各個(gè)站點(diǎn)，在總線上的各個(gè)通訊站點(diǎn)，不再是數(shù)據(jù)采集和控制執(zhí)行的終端，而是具有控制邏輯的大腦。
