DCS

The singlehanded close communication protocol was used in DCS, standard communication protocol was used in FCS.

DCS采用独家封闭的议,FCS采用标准的议。

In many cases, the DCS was merely a digital replacement of the same functionality provided by analog controllers and a panelboard display.

很多情况下，直接数字控制仅仅是一种数字式替，它的功能同多个模拟控制器和一个面板显示器所提供的功能一样。
