 早期的PLC以數字量的順序控制為主。隨著PLC功能不斷擴充，PLC增加了模擬量控制功能、PID調節(jié)功能、通訊聯網功能及分級控制功能等，在過去DCS占統(tǒng)治地位的化工、冶金等行業(yè)也可由PLC進行控制。但PLC難以組成大型、復雜、綜合的系統(tǒng)，如果過多的PC企圖通過網絡與過多的 PLC通訊，則可能導致瓶頸現象及計時上的困難。  

    DCS是由模擬儀表控制系統(tǒng)發(fā)展而來，初期的功能以回路調節(jié)為主，之后又加入了順序控制的功能。DCS的設計思想是操作管理集中，控制分散以提高整個系統(tǒng)的可靠性及管理能力。DCS的上述優(yōu)勢使它在控制系統(tǒng)的市場仍占主流。  但DCS比PLC價位高，對一些資金有限的中小型企業(yè)有時難以承受。  

    本文探討的這種混合式控制系統(tǒng)整合了PLC與DCS的優(yōu)勢，對需要實現低成本自動化（LCA）的場合尤為適用。
