6、 I/O是什么？ 
控制系统需要建立信号的输入和输出通道，这就是I/O。DCS中的I/O一般是模块化的，一个I/O模块上有一个或多个I/O通道，用来连接传感器和执行器（调节阀）。 
7、 什么是I/O单元？ 
通常，一个过程控制站是有几个机架组成，每个机架可以摆放一定数量的模块。CPU所在的机架被称为CPU单元，同一个过程站中只能有一个CPU单元，其他只用来摆放I/O模块的机架就是I/O单元。 
8、I/O单元和CPU单元是如何连接的？ 
I/O单元与CPU是通过现场总线连接的。 
9、 什么是现场总线？ 
现场总线是应用于过程控制现场的一种数字网络，它不仅包含有过程控制信息交换，而且还包含设备管理信息的交流。通过现场总线，各种智能设备（智能变送器、调节法、分析仪和分布式I/O单元）可以方便地进行数据交换，过程控制策略可以完全在现场设备层次上实现。目前，使用较多的现场总线主要是FUNDATION fieldbus***会现场总线（FF总线）和Profibus现场总线。应用现场总线技术可以将各种分布在控制现场的相关智能设备和I/O单元方便的连接在一起，构成控制系统，这种结构已经成为DCS发展的趋势。
