1.TDC2000 produced many important achievements in the field of control system 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 characteristics of the whole TDC2000 are 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 functional allocation is still used by some DCS control vendors.
2. As the most typical DCS system, TDC3000 further reflects the concept of decentralized control, with the following main features:
To meet the needs of large-scale production, a two-layer control network architecture is used. Each LCN can connect 10 UCNs, and each UCN can connect 32 pairs of redundant controllers. 64 CNS can also be connected through NG.
