詳情資料

TRICONEX控制系統是基于三重模件冗余(TMR)結構的的容錯控制器。TMR是集成了三路隔離的、并行工作的控制系統，并在每一個獨立的控制系統中執行廣泛的診斷。系統采用三取二邏輯表決方式，提供高度完善、無差錯、不間斷的過程操作，不會因為單點的故障而導致系統失效。

MP控制器采用三個獨立通道，每個通道與另外二個通道并行獨立執行應用程序，對從現場來得所有數字量輸入/輸出信號采用通過獲得的硬件表決器進行表決，而模擬信號則是中間值選擇處理。因為每個通道與其他通道隔何通道單點故障不會影響其他通道。如果一個通道發生硬件故障，而其他通道不顧及它。在此期間控制器不間斷處理的情況下，可方便地在線插拔和替換故障模塊。

系統的使用非常簡單，因為從用戶角度來看，TMR系統的操作與單通道的控制系統是一樣的。用戶可將傳感器和執行器連接在單一的接線端子上，只需編寫一套應用程序邏輯，剩下的工作就全由控制系統管理和處理了。

系統對每個獨立的分電路，每個模件和每個功能電路都進行廣泛的診斷，對操作錯誤進行監測和報告。對應用和操作中的所有診斷信息均被貯存。這些診斷數據可供程序員使用，可修改控制器的執行或直接進行過程維護。

英文資料

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.
