Overview of TRICON Safety Instrumented System

The Tricon Safety Instrumented System (SIS) by Schneider Electric is a high-availability, fault-tolerant controller designed for critical industrial applications. Utilizing Triple-Modular Redundant (TMR) technology, it ensures safe shutdown and process monitoring, achieving SIL 3 certification to protect personnel and equipment. It is widely used for emergency shutdown and fire/gas safety.

Product features

Provides Triple Modular Redundant (TMR) architecture whereby each of three identical system channels independently executes the control program, and specialized hardware/software mechanisms “vote” all inputs and outputs.
Withstands harsh industrial environments.
Enables field installation and repair to be done at the module level while the controller remains online. Replacing an I/O module does not disturb field wiring.
Supports up to 118 I/O modules (analog and digital) and optional communication modules that interface with Modbus masters and slaves, Foxboro® and Honeywell™ Distributed Control Systems (DCS), other Triconex controllers in Peer-to-Peer networks, and external host applications on Ethernet networks.
Provides integral support for remote I/O modules located as far away as 7.5 miles (12 kilometers) from the Main Chassis, using SRXM modules.
Executes control programs developed and debugged with TriStation™ 1131 Developer's Workbench Software or TriStation MSW software.
Provides intelligence in the input and output modules to reduce the workload of the Main Processors. Each I/O module has three microprocessors. Input module microprocessors filter and debounce the inputs and diagnose hardware faults on the module. Output module microprocessors supply information for the voting of output data, check loopback data from the output terminal for final validation of the output state, and diagnose field-wiring problems.
Provides integral online diagnostics with adaptive-repair capabilities.
Allows normal maintenance while the Tricon controller is operating, without disturbing the controlled process.
Supports transition to a hot-spare I/O module for critical applications where prompt service may not be possible.

Applications

Emergency Shutdown (ESD)

Safe shutdown of processes.

Fire and Gas Protection (F&G)

Detecting and mitigating fire or gas leaks.

Burner Management (BMS)

Managing burner safety.

High Integrity Pressure Protection (HIPPS)

Preventing over-pressurization.

System Configuration

Physically, a basic Tricon controller consists of Main Processors and I/O modules, communication modules, the chassis enclosing the modules, field wiring connections, and a TriStation PC. This section briefly describes these components and provides general specifications.

Tricon modules are field-replaceable units consisting of an electronic assembly housed in a metal spine. Each module has a protective cover that ensures no components or circuits are exposed even when a module is removed from the chassis. Offset backplane connectors make it impossible to plug a module in upside down, and keys on each module prevent the insertion of modules into incorrect slots. The Tricon controller supports digital and analog input and output points, as well as pulse and thermocouple inputs and multiple communication protocols.
