Tricon 系统的主要特点 Tricon System Major Feature

Tricon System Overall Introduction Tricon系统概述

Over 6000 Tricon System Installed in Worldwide世界已应用了6000多套Tricon TMR系统

TÜV Certified for AK5/AK6 Safety Applications获得TUV AK5/AK6 级安全认证

TRICONEX Product also meet the international standards - TUV, CSA, FM, IEC, UL, CE ,1E MarkTRICONEX 产品连续获得国际标准化组织的认证---- TUV, CSA, FM, IEC, UL, CE

TRICONEX Headquarters and Manufacturing Facility is ISO 9000 certifiedTRICONEX 的每个制造机构(包括制造设备)都获得 ISO 9000 认证

Tricon – TMR Fault-Tolerant ControllerTricon - TMR 容错控制系统Definition of Tricon – TMR Fault Tolerance Controller: Tricon - TMR 容错控制系统的定义:Identifies and compensates for failed control system elements and allows on-line repair while continuing its assigned task without process interruption. 识别并补偿控制系统的错误并允许在不影响正常生产的情况下在线维修。 High Safety Integrity - High Safety Availability due to TMR architecture, diagnostics, and on-line repair 高安全性和高可用性 –它是通过三重模件冗余结构(TMR)提供容错能力的。此系统由三个完全相同的系统通道组成,自诊断以及在线维修。 High Availability - Eliminates spurious (false) trips

高可用性 - 消除因硬件故障造成的误停车。

TMR for High AvailabilityTMR – 高可利用率 Triple Modular Redundancy provides correct control in presence of any Single fault三重化组件提供正确的控制，即使存在任何单一故障也不影响整体效果。

Ability to operate with 3, 2 or 1 MP(s) before shutdown停车前的主处理机工作模式为 3-2-1。

On-line repair provides replacement of faulty module without disrupting control再线维护，提供更换故障组件的能力，且不影响控制(不停车)

Number of false shutdowns (trips) reduced降低因硬件错误而导致停车的次数。

Sequential and regulatory control capability提供连续控制、顺序控制、逻辑控制的能力。

Tricon TMR vs. All Other PLC TechnologiesTricon TMR 系统与其它PLC的比较

Diagnostics - Catch problems before it become a threat to the process !诊断系统- 在系统发生危险之前抓住隐患！(瞬态和稳态)。

On-Line Repair - A failed module can be pull out on-line (Hot Spare).再线维护- 故障硬件可以被再线更换！

No Single Point of Failure - Isolation, so that a problem will not “bleed over” or affect or “propagate” to other legs.无单点故障–采用隔离技术，每一通道内部的三重电

路都是独立的。

Comprehensive diagnostics are embedded in the system, independent of user written application programming ! 自诊断内置于Tricon 的硬件内，不需要用户编写应用程序
