Description​​

The​​TRICONEX 3720​​is the Main Processor Module for the TRICON v9 and v10 Triple Modular Redundant(TMR)Safety Instrumented System(SIS).This module is the central brain of the controller,responsible for executing the safety logic across three parallel channels.It is designed for the most critical safety applications,such as Emergency Shutdown(ESD)and Fire&Gas(F&G)systems,where maximum availability and fault tolerance are non-negotiable.

​​Application Scenarios​​

On an offshore oil and gas platform,a high-pressure gas detection event must trigger an immediate and reliable emergency shutdown to prevent catastrophe.The​​TRICONEX 3720​​Main Processor,at the heart of the platform’s Safety Instrumented System(SIS),receives the triplicated signal from the gas detectors.Its three independent processors execute the identical safety logic simultaneously.The system performs a 2-out-of-3(2oo3)voting on the result.Even if one of the three​​3720​​processor channels were to develop a fault,the system would still produce a correct shutdown command based on the agreement of the two healthy channels,ensuring both safety and availability.This scenario underscores the module’s critical role in fault-tolerant safety control.

​​Technical Principles and Innovative Values​​

The​​TRICONEX 3720​​embodies the core principles of fault-tolerant safety system design.

​​Innovation Point 1:True Triple Modular Redundant(TMR)Architecture:​​The​​3720​​module contains three independent,parallel processor channels operating in perfect synchronization.Each channel executes the same application logic,and the results are compared via a hardware-based voter.This ensures that a single failure within the processor does not cause a system failure or a spurious shutdown.

​​Innovation Point 2:Continuous Fault Detection and Isolation:​​The module performs rigorous online diagnostics,constantly checking the health of each processor channel,its memory,and the inter-channel communication paths.If a fault is detected,it is isolated to the faulty channel,which is then taken offline while the remaining two channels continue to maintain a safe state,ensuring high system availability.

​​Innovation Point 3:Seamless Integration with TMR I/O System:​​The​​3720​​is designed to work with the complete TRICON TMR I/O system(e.g.,Analog Input​​3704A​​,Digital Input​​3503E​​).It manages the triplicated data acquisition from field sensors and the voting for output commands,providing a fully integrated,end-to-end TMR solution.

​​Innovation Point 4:Hot Swappability for Maximum Availability:​​The​​3720​​module can be safely removed and replaced while the TRICON system remains powered and operational.This capability is crucial for critical processes that cannot tolerate downtime,allowing for maintenance and upgrades without compromising the safety function.

​​Application Cases and Industry Value​​

​​Case 1:Gas Compressor Station Emergency Shutdown:​​A natural gas compressor station uses a TRICON system with a​​3720​​Main Processor as its Emergency Shutdown(ESD)system.The system monitors suction and discharge pressures,turbine speeds,and vibration levels.When a high discharge pressure threatened to damage the pipeline,the​​3720​​processor reliably executed the shutdown logic.The system’s high availability prevented a nuisance trip months earlier when a transient power glitch affected one of the three processor channels;the system remained operational on the two healthy channels,and the faulty module was replaced online,avoiding a costly shutdown of the station.

​​Case 2:Chemical Plant Burner Management System(BMS):​​A large chemical reactor is heated by multiple burners managed by a TRICON SIS.The​​3720​​processor continuously monitors flame status,fuel pressure,and airflow for each burner.Its deterministic scan time and high-integrity logic execution ensure that any dangerous condition,such as a flame failure,results in a fast and guaranteed fuel shutoff to the affected burner,preventing a furnace explosion and protecting personnel and equipment.
