分散型控制系統DCS（Distributed Control System），是以微處理機為核心。實現了控制功能的分散與操作管理的集中。是一種分布式計算機控制系統，它是在以往的工業控制計算機和模擬控制儀表的基礎上發展起來的，是集兩者優點于一體的理想的過程控制系統。μXL（ Micro Excel）中小規模集散型控制系統匯集了過程控制自動化（PA）技術和工廠自動化（FA）技術。其結構、性能、控制、監視、操作和工程技術業務機能都比以往的DCS有重大改進。
μXL集散控制系統由以下三大部分構成：
l 以MOPS或MOPL操作站為中心及相應的打印機、彩色拷貝機等支持設備構成的人機接口。
l 以MFCU或MFCD現場控制單元、MFMU現場監視單元及其相應的輸入/輸出擴充單元、過程I/O設備、PLC等組成的過程監控系統。
l 由RL總線、中繼器、光適配器組成的通信系統。
