DCS的特点：

（1）控制功能强。可实现复杂的控制规律，如串级、前馈、解耦、自适应、和非线性控制等。也可实现顺序控制。

（2）系统可靠性高。

（3）采用CRT操作站有良好的人机界面。

（4）软硬件采用模块化积木式结构。

（5）系统容易开发。

（6）用组态软件，编程简单，操作方便。

（7）有良好的性价比。

通过数据公路的设计参数，基本上可以了解一个特定DCS或PLC系统的相对优点与弱点。

（1）系统能处理多少I/O信息。

（2）系统能处理多少与控制有关的控制回路的信息。

（3）能适应多少用户和装置（CRT、控制站等）。

（4）传输数据的完整性是怎样检查的。

（5）数据公路的允许长度是多少。

（6）数据公路能支持多少支路。

（7）数据公路是否能支持由其它制造厂生产的硬件（可编程序控制器、计算机、数据记录装置等）。为保证通信的完整，大部分DCS或PLC厂家都能提供冗余数据公路。

DCS features:

(1) Strong control function. It can realize complex control laws, such as cascade, feedforward, decoupling, adaptive, and nonlinear control. Sequence control is also possible.

(2) High system reliability.

(3) The CRT operation station has a good man-machine interface.

(4) The software and hardware adopt modular building block structure.

(5) The system is easy to develop.

(6) With configuration software, programming is simple, easy to operate.

(7) Good cost performance.

Through the design parameters of the data highway, you can basically understand the relative strengths and weaknesses of a particular DCS or PLC system.

(1) How much I/O information the system can process.

(2) How much control loop information related to control can be processed by the system.

(3) How many users and devices can be adapted (CRT, control station, etc.).

(4) How the integrity of the transmitted data is checked.

(5) What is the allowable length of the data highway?

(6) How many branches the data highway can support.

(7) Whether the data highway can support hardware produced by other manufacturers (programmable controllers, computers, data recording devices, etc.). In order to ensure the integrity of communication, most DCS or PLC manufacturers can provide redundant data highways.
