控制器是DCS的核心部件，它相當于一臺PC機。有的DCS的控制器本身就是PC機。它主要有CPU、RAM、E2PROM和ROM等芯片，還有兩個接口，一個向下接收I/O總線來的信號，另一個接口是向上把信號送到網絡上與人機界面相連。ROM用來存貯完成各種運算功能的控制算法（有的DCS稱為功能塊庫）。在庫中存功能塊，如控制算法PID、帶死區PID，積分分離PID，算術運算加、減、乘、除、平方、開方、函數運算一次濾波、正弦、余弦、X-Y函數發生器、超前-滯后；比較*的算法有史密斯預估，C語言接口、矩陣加、矩陣乘；邏輯運算有邏輯與、邏輯或、邏輯非、邏輯與非等。通常用站功能塊不僅把模擬量和開關量結合起來，還與人連系起來。功能塊越多，用戶編寫應用程序（即組態）越方便。組態按照工藝要求，把功能塊連接起來形成控制方案。把控制方案存在E2PROM中。因為E2PROM可以擦寫，組態要隨工藝改變而改變，所以把組態存在E2PROM中。不同用戶有不同組態。組態時，用戶從功能塊庫中選擇要的功能塊，填上參數，把功能塊連接起來。形成控制方案存到E2PROM中。這時控制器在組態方式，投入運行后就成為運行方式。

人機界面有4種不同形式的結點，它們是操作站、工程師工作站、歷史趨勢站和動態數據服務器。

　　 操作站安裝有操作系統、監控軟件和控制器的驅動軟件。顯示系統的標簽、動態流程圖和報警信息。

　　工程師工作站給控制器組態（CAD），也可以給操作站組態（作動態流程圖）。如果監控軟件作圖能力很強，作圖工作可以由監控軟件獨立完成。工程師站的另外一個功能是讀控制器的組態，用于控制器升級，查找故障。我們稱之為逆向工程師站。

　　歷史趨勢站用于存儲歷史數據，一般用磁盤陣列（稱為RAID技術）。
