3301 TRICONEX Controller Card Each TMR digital input module has three separate sets of electronics, called channels, that independently process the module’s field data. Each channel places the processed data in an array and transfers that array to the MP associated with that channel upon request. MPs votes on the data before passing it to the application. The DI module includes complete, continuous diagnostics for each channel. If the diagnostic detects a fault on any channel, the fault indicator lights up and activates the system alert. The fault indicator identifies the channel fault, not the entire module fault. The D module continuously validates the system’s ability to detect transitions to the opposite state. The D| module is guaranteed to function in the event of a single failure and to continue to function in the event of multiple failures. The D module supports the hot standby module. Each DI module is mechanically locked to prevent improper installation in the configured substrate. The Model 3301 D| module is available on the following substrates: Model 2301 for curved applications. D1 External terminal substrate for solid-state input external terminal panels in Gauller applications, or Type 9573-610 DI hazardous site external terminal panels
Key features of the Tricon control system
Tricon is a highly fault-tolerant programmable and process control technology
Its characteristics are as follows:
A, provides a three-mode multi-remainder structure (TMR) with three identical subcircuits, each performing an independent degree of control. There is also a dedicated hardware/software architecture for “voting” on inputs and outputs
Able to endure harsh industrial environments.
C. It can be installed in the field and module level D can be installed and repaired online in the field without interfering with the field wiring. Up to 118 I/O modules (analog and digital) and optional communication modules are supported. Communication modules can be connected to Modbus hosts and slave devices, or to Foxboro and Honeywel Distributed control Systems (DCS), other Tricons in peer-to-peer networks, and external hosts in TCP/IP networks.
E. Can support remote I/O modules up to 12 km from the mainframe.
F. Develop and debug control programs using programming software based on Windows NT systems. G. Intelligent functions in the input and output modules reduce the workload of the main processor. Each /0 module has three microprocessors. The input module’s microprocessor filters and repairs the input and diagnoses hardware failures on the module, the output module’s microprocessor provides information for voting on the output data, checks the validity of the output state by the feedback loop voltage at the output, and can diagnose field line problems.
H. Provide comprehensive online diagnostic and repair capabilities.
When Tricon is up and running, routine maintenance can be performed without interrupting the control process.
J. Provide “hot backup” support for I/O modules, which can be used in certain emergency situations where service cannot be provided in time.

Tricon控制系統(tǒng)的主要特點
Tricon是一種高容錯的可編程和過程控制技術
其特點如下:
A,提供三模幾余結構(TMR),具有三個相同的子電路，每個子電路執(zhí)行獨立程度的控制。還有一個專用的硬件/軟件架構，用于對輸入和輸出進行“表決”
能夠忍受惡劣的工業(yè)環(huán)境.
C.它可以在現(xiàn)場安裝，并且可以在不干擾現(xiàn)場布線的情況下在現(xiàn)場在線安裝和修復模塊級D.支持多達118個I/O模塊(模擬和數(shù)字)和可選通信模塊。通信模塊可以連接到Modbus主機和從屬設備，或連接到Foxboro和Honeywel分布式控制系統(tǒng)(DCS)，對等網(wǎng)絡中的其他Tricons，以及TCP/IP網(wǎng)絡中的外部主機。
E.可以支持距離大型機最遠12公里的遠程I/O模塊。
F.使用基于Windows NT系統(tǒng)的編程軟件開發(fā)和調(diào)試控制程序。G.輸入和輸出模塊中的智能功能可減少主處理器的工作負荷。每個/0模塊有三個微處理器。輸入模塊的微處理器過濾和修復輸入，并診斷模塊上的硬件故障，輸出模塊微處理器為輸出數(shù)據(jù)的表決提供信息，通過輸出端的反饋回路電壓檢查輸出狀態(tài)的有效性，并能診斷場線問題。
H.提供全面的在線診斷和修復能力。
Tricon啟動和運行時，可以進行日常維護，而不會中斷控制過程.
J.為I/O模塊提供“熱備用”支持，可用于某些無法及時提供服務的緊急情況。
