TRIC0NEX D03401三重模块化冗余主处理器模块

通过三模块冗余(TMR ）架构。TMR在一个控制系统中集成了三个隔离的并联控制系统和广泛的诊断。该系统使用三选二投票,以提供高完整性、无错误、不间断的过程操作，无单点故障。

Tricon控制器使用三个相同的通道。每个通道与其他两个通道并行独立地执行控制程序。专门的硬件/软6件投票机制对现场的所有数字输入和输出进行鉴定和验证，而模拟输入则经过中间值选择过程。

因为每个通道都与其他通道隔离，所以任何通道中的单点故障都不会传递到另一个通道。如果一个通道上确实发生硬件故障，则其他通道将覆盖该故障。同时，故障模块可以在控制器在线时轻松移除和更换，而不会中断过程。

With three-module redundancy (TMR) architecture. TMR integrates three isolated parallel control systems and extensive diagnostics in a single control system. The system uses two out of three voting to provide high integrity, error-free, uninterrupted process operation with no single point of failure.

The Tricon controller uses three identical channels. Each channel executes the control program independently and in parallel with the other two channels. A dedicated hardware/software 6-piece voting mechanism identifies and validates all digital inputs and outputs in the field, while analog inputs go through a mid-value selection process.

Because each channel is isolated from the others, a single point of failure in any channel is not transmitted to another channel. If a hardware failure does occur on one channel, the other channels will override the failure. At the same time, the failed module can be easily removed and replaced while the controller is online without interrupting the process.
