TRICON 4352B Detailed Introduction

TRICON 4352B is a control system produced by Triconex(now part of Invensys Operations Management).It adopts a triple modular redundant(TMR)architecture to provide error-free and uninterrupted control.The system is particularly suitable for critical control applications that require high reliability and safety,such as refining,petrochemicals,upstream and midstream oil and gas,chemicals and specialty chemicals,power generation and other fields.

Technical Features

Triple Modular Redundancy(TMR)Architecture

The fault tolerance of TRICON 4352B is achieved through the TMR architecture.From the input module to the main processor to the output module,the entire design adopts a fully triple architecture.

Each I/O module contains three independent branch circuits to ensure that the system can still operate normally when a single component fails.

High-speed bus system(TriBus)

The three main processors communicate with each other using a proprietary high-speed bus system called TriBus.Each time the three main processors are scanned,they synchronize and communicate with their two neighbors through TriBus.

TriBus also verifies the input and output data to ensure the accuracy and integrity of the data.

Programmability and flexibility

TRICON 4352B supports user-written applications and provides a wealth of programming tools and interfaces to facilitate users to customize and expand according to actual needs.

Reliability and safety

The system uses a variety of redundancy and fault-tolerant technologies,including power redundancy,processor redundancy,I/O redundancy,etc.,to ensure that the system can operate stably in various harsh environments.

At the same time,the system also provides a wealth of fault detection and diagnosis functions to facilitate users to find and solve problems in a timely manner.

Compatibility

TRICON 4352B has good compatibility and can be easily integrated and compatible with existing or future systems.
