控制器是DCS的核心部件，它相當(dāng)于一臺PC機(jī)。有的DCS的控制器本身就是PC機(jī)。它主要有CPU、RAM、E2PROM和ROM等芯片，還有兩個(gè)接口，一個(gè)向下接收I/O總線來的信號，另一個(gè)接口是向上把信號送到網(wǎng)絡(luò)上與人機(jī)界面相連。ROM用來存貯完成各種運(yùn)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(qū)PID，積分分離PID，算術(shù)運(yùn)算加、減、乘、除、平方、開方、函數(shù)運(yùn)算一次濾波、正弦、余弦、X-Y函數(shù)發(fā)生器、超前-滯后；比較*的算法有史密斯預(yù)估，C語言接口、矩陣加、矩陣乘；邏輯運(yùn)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(guān)量結(jié)合起來，還與人連系起來。功能塊越多，用戶編寫應(yīng)用程序（即組態(tài)）越方便。組態(tài)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?yàn)镋2PROM可以擦寫，組態(tài)要隨工藝改變而改變，所以把組態(tài)存在E2PROM中。不同用戶有不同組態(tài)。組態(tài)時(shí)，用戶從功能塊庫中選擇要的功能塊，填上參數(shù)，把功能塊連接起來。形成控制方案存到E2PROM中。這時(shí)控制器在組態(tài)方式，投入運(yùn)行后就成為運(yùn)行方式。
人機(jī)界面有4種不同形式的結(jié)點(diǎn)，它們是操作站、工程師工作站、歷史趨勢站和動(dòng)態(tài)數(shù)據(jù)服務(wù)器。
操作站安裝有操作系統(tǒng)、監(jiān)控軟件和控制器的驅(qū)動(dòng)軟件。顯示系統(tǒng)的標(biāo)簽、動(dòng)態(tài)流程圖和報(bào)警信息。
工程師工作站給控制器組態(tài)（CAD），也可以給操作站組態(tài)（作動(dòng)態(tài)流程圖）。如果監(jiān)控軟件作圖能力很強(qiáng)，作圖工作可以由監(jiān)控軟件獨(dú)立完成。工程師站的另外一個(gè)功能是讀控制器的組態(tài)，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(shù)據(jù)，一般用磁盤陣列（稱為RAID技術(shù)）。
