1.TDC2000产生了当时控制系统领域的许多重要成果,如冗余控制器、冗余控制网络(DH-Data Hiway)、人机界面等。

根据分布原则，整个TDC2000的基本功能分布特如下:控制网络采用单层冗余结构;操作站负责操作和数据存储;不同的控制器实现不同的过程控制等等。这种基本的功能分配仍被一些DCS的控制厂 商所采用。

2.作为最典型的DCS系统，TDC3000进一步体现了 分散控制的理念,具有以下主要特点:

为满足大规模生产的需要，采用两层控制网络架构，每个LCN可以连接10个UCN,每个UCN可以连接32对冗余控制器。64个Icn也可以通过NG连接。

1.TDC2000 produced many important achievements in the field of control systems at that time, such as redundant controller, redundant control network (DH-Data Hiway), man-machine interface, etc.

According to the distribution principle, the basic function distribution of the whole TDC2000 is as follows: the control network adopts single-layer redundancy structure; The operation station is responsible for operation and data storage; Different controllers realize different process control and so on. This basic function assignment is still used by some DCS control manufacturers.

2. As the most typical DCS system, TDC3000 further reflects the concept of decentralized control, with the following main features:

In order to meet the needs of large-scale production, a two-layer control network architecture is adopted. Each LCN can connect 10 UCNs, and each UCN can connect 32 pairs of redundant controllers. 64 ICNs can also be connected through NG.
