DCS

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

DCS采用独家封闭通信协议,FCS采用标准通信协议。

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，直接数控制仅仅是一种数，能同多个模拟控制器和一个面板显示器所提供能一样。
