4、 DCS的控制程序是由谁执行的?
DCS的控制决策是由过程控制站完成的,所以控制程序是由过程控制站执行的。
5、 过程控制站的组成如何?
DCS的过程控制站是一个完整的计算机系统,主要由电源、CPU(****处理器)、网络接口和I/O组成
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。
