(1)現場控制單元的軟件系統
現場控制單元的軟件主要包括以實時數據庫為中心的數據巡檢、控制算法、控制輸出和網絡通信等軟件模塊組成。
實時數據庫起到了中心環節的作用，在這里進行數據共享，各執行代碼都與它交換數據，用來存儲現場采集的數據、控制輸出以及某些計算的中間結果和控制算法結構等方面的信息。數據巡檢模塊用以實現現場數據、故障信號的采集，并實現必要的數字濾波、單位變換、補償運算等輔助功能。dcs的控制功能通過組態生成，不同的系統，需要的控制算法模塊各不相同，通常會涉及以下一些模塊：算術運算模塊、邏輯運算模塊、pid控制模塊、變型pid模塊、手自動切換模塊、非線性處理模塊、執行器控制模塊等等。控制輸出模塊主要實現控制信號以故障處理的輸出。
(2)操作站的軟件系統
dcs中的操作站用以完成系統的開發、生成、測試和運行等任務，這就需要相應的系統軟件支持，這些軟件包括操作系統、編程語言及各種工具軟件等。一套完善的dcs，在操作站上運行的應用軟件應能實現如下功能：實時數據庫、網絡管理、歷史數據庫管理、圖形管理、歷史數據趨勢管理、數據庫詳細顯示與修改、記錄報表生成與打印、人機接口控制、控制回路調節、參數列表、串行通信和各種組態等。
