TRICONEX控制系统是基于三重模件冗余(TMR)结构的的容错控制器。TMR是集成了三路隔离的、并行工作的控制系统，并在每一个独立的控制系统中执行广泛的诊断。系统采用三取二逻辑表决方式，提供高度完善、无差错、不间断的过程操作，不会因为单点的故障而导致系统失效。

MP控制器采用三个独立通道，每个通道与另外二个通道并行独立执行应用程序，对从现场来得所有数字量输入/输出信号采用通过获得专利的硬件表决器进行表决，而模拟信号则是中间值选择处理。因为每个通道与其他通道隔离，任何通道单点故障不会影响其他通道。如果一个通道发生硬件故障，而其他通道不顾及它。在此期间控制器不间断处理的情况下，可方便地在线插拔和替换故障模块。

系统的使用非常简单，因为从用户角度来看，TMR系统的操作与单通道的控制系统是一样的。用户可将传感器和执行器连接在单一的接线端子上，只需编写一套应用程序逻辑，剩下的工作就全由控制系统管理和处理了。

系统对每个独立的分电路，每个模件和每个功能电路都进行广泛的诊断，对操作错误进行监测和报告。对应用和操作中的所有诊断信息均被贮存。这些诊断数据可供程序员使用，可修改控制器的执行或直接进行过程维护。

英文资料

The TRICONEX safety control system is the most advanced fault-tolerant controller based on the Triple Modular Redundancy (TMR) structure. TMR is a control system that integrates three isolated and parallel operations, and performs extensive diagnostics in each independent control system. The system adopts a two out of three logical voting method, providing highly complete, error free, and uninterrupted process operation, without causing system failure due to single point failures.

The MP controller adopts three independent channels, each of which executes the application program independently in parallel with the other two channels. All digital input/output signals from the field are voted through patented hardware voting devices, while analog signals are processed through intermediate value selection. Because each channel is isolated from other channels, Single point of failure of any channel will not affect other channels. If a hardware failure occurs in one channel and other channels ignore it. During this period, the controller can easily plug, unplug, and replace faulty modules online without interruption.

The use of the system is very simple because from the user's perspective, the operation of the TMR system is the same as that of a single channel control system. Users can connect sensors and actuators to a single wiring terminal, simply write a set of application logic, and the rest of the work is managed and processed by the control system.

The system conducts extensive diagnosis on each independent sub circuit, module, and functional circuit, monitoring and reporting operational errors. All diagnostic information in the application and operation is stored. These diagnostic data can be used by programmers to modify the execution of the controller or directly perform process maintenance.
