【功能描述】
制造商:霍尼韦尔
产品编号:51196655-100
产品类型:TDC 3000电源模块
51196655-100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的基本功能分布特点如下: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,51196655-100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lcn也可以通过NG连接。
三层控制平台
1)PMX实现最基本的回路调节、逻辑联动、顺序控制和复杂回路控制。
2)AM实现高级控制
3)VAX优化控制
引入紧急停车系统SM,实现安全生产保障。

【英文介绍】
Manufacturer: Honeywell
Product Number :51196655-100
Product type :TDC 3000 power module
51196655-100 produced many important achievements in the field of control systems at the time, such as redundant controllers, redundant control networks (DH-Data Hiway), human-machine interfaces, and so on.
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 function allocation is still used by some DCS control vendors.
2. As the most typical DCS system, 51196655-100 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 LCNS can also be connected via NG.
Three-layer control platform
1)PMX implements the most basic loop regulation, logical linkage, sequence control and complex loop control.
2)AM to achieve advanced control
3)VAX optimization control
Emergency shutdown system SM is introduced to ensure safe production.
