制造商:霍尼韦尔
产品编号:51196655-100
产品类型:TDC 3000电源模块
我们所有的电源都是为内部线路频率时钟固定的。如果NIM需要事件序列(SOE)功能，则时钟主机、时钟从机和具有SOE要求的NIM必须固定,以便与外部时钟一起使用。 所有其它节点都被固定用于内部(线路频率)时钟。跳线位于J102位置，并清楚地标记为(INT)和(EXT)。

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，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。

TDC2000 produced many important achievements in the field of control systems at that time, such as redundant controllers, redundant control networks (DH Data Hiways), human-machine interfaces, etc. According to the distribution principle, the basic functional distribution characteristics of the entire TDC2000 are as follows: the control network adopts a single-layer redundant structure; The operation station is responsible for operation and data storage; Different controllers implement different process controls, and so on. This basic functional allocation is still adopted by some DCS control manufacturers.
As the most typical DCS system, TDC3000 further embodies the concept of decentralized control and has the following main characteristics: 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 through NG.
