控制器是DCS的核心部件，它相当于一台PC机。有的DCS的控制器本身就是PC机。它主要有CPU、RAM、E2PROM和ROM等芯片，还有两个接口，一个向下接收I/O总线来的信号，另一个接口是向上把信号送到网络上与人机界面相连。ROM用来存贮完成各种运算功能的控制算法（有的DCS称为功能块库）。在库中存功能块，如控制算法PID、带死区PID，积分分离PID，算术运算加、减、乘、除、平方、开方、函数运算一次滤波、正弦、余弦、X-Y函数发生器、超前-滞后；比较*的算法有史密斯预估，C语言接口、矩阵加、矩阵乘；逻辑运算有逻辑与、逻辑或、逻辑非、逻辑与非等。通常用站功能块不仅把模拟量和开关量结合起来，还与人连系起来。功能块越多，用户编写应用程序（即组态）越方便。组态按照工艺要求，把功能块连接起来形成控制方案。把控制方案存在E2PROM中。因为E2PROM可以擦写，组态要随工艺改变而改变，所以把组态存在E2PROM中。不同用户有不同组态。组态时，用户从功能块库中选择要的功能块，填上参数，把功能块连接起来。形成控制方案存到E2PROM中。这时控制器在组态方式，投入运行后就成为运行方式。

人机界面有4种不同形式的结点，它们是操作站、工程师工作站、历史趋势站和动态数据服务器。

　　 操作站安装有操作系统、监控软件和控制器的驱动软件。显示系统的标签、动态流程图和报警信息。

　　工程师工作站给控制器组态（CAD），也可以给操作站组态（作动态流程图）。如果监控软件作图能力很强，作图工作可以由监控软件独立完成。工程师站的另外一个功能是读控制器的组态，用于控制器升级，查找故障。我们称之为逆向工程师站。

　　历史趋势站用于存储历史数据，一般用磁盘阵列（称为RAID技术）。
