【功能描述】
制造商:霍尼韋爾
產(chǎn)品編號(hào):51196655-100
產(chǎn)品類(lèi)型:TDC 3000電源模塊
51196655-100產(chǎn)生了當(dāng)時(shí)控制系統(tǒng)領(lǐng)域的許多重要成果，如冗余控制器、冗余控制網(wǎng)絡(luò)(DH-Data Hiway)、人機(jī)界面等。
根據(jù)分布原則，整個(gè)TDC2000的基本功能分布特點(diǎn)如下:控制網(wǎng)絡(luò)采用單層冗余結(jié)構(gòu)；操作站負(fù)責(zé)操作和數(shù)據(jù)存儲(chǔ)；不同的控制器實(shí)現(xiàn)不同的過(guò)程控制等等。這種基本的功能分配仍被一些DCS的控制廠商所采用。
2.作為最典型的DCS系統(tǒng)，51196655-100進(jìn)一步體現(xiàn)了分散控制的理念，具有以下主要特點(diǎn):
為滿(mǎn)足大規(guī)模生產(chǎn)的需要，采用兩層控制網(wǎng)絡(luò)架構(gòu)，每個(gè)LCN可以連接10個(gè)UCN，每個(gè)UCN可以連接32對(duì)冗余控制器。64個(gè)lcn也可以通過(guò)NG連接。
三層控制平臺(tái)
1)PMX實(shí)現(xiàn)最基本的回路調(diào)節(jié)、邏輯聯(lián)動(dòng)、順序控制和復(fù)雜回路控制。
2)AM實(shí)現(xiàn)高級(jí)控制
3)VAX優(yōu)化控制
引入緊急停車(chē)系統(tǒng)SM，實(shí)現(xiàn)安全生產(chǎn)保障。

【英文介紹】
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.
