MFG: TRICONEX, Made in USA

Triconex is both the name of a Schneider Electric brand that supplies products, systems and services for safety,

critical control and turbomachinery applications and the name of its hardware devices that utilize its TriStation application software.

Triconex products are based on patented Triple modular redundancy (TMR) industrial safety-shutdown technology.

Today, Triconex TMR products operate globally in more than 11,500 installations, making Triconex the largest TMR supplier in the world.

Triconex system is based on the TMR patented technology that supports up to SIL 3 and is usually used as a safety rather than control system.[1]

Fault tolerance in the Tricon is achieved by means of a Triple-Modular Redundant(TMR) architecture.

The Tricon provides error-free, uninterrupted control in the presence of either hard failures of components,

or transient faults from internal or external sources. The Tricon is designed with a fully triplicated architecture throughout,

from the input modules through the Main Processors to the output modules. Every I/O module houses the circuitry for three independent legs.

Each leg on the input modules reads the process data and passes that information to its respective Main Processor.

The three Main Processors communicate with each other using a proprietary high-speed bus system called the TriBus.

Once per scan, the three Main Processors synchronize and communicate with their two neighbors over the TriBus. The Tricon votes digital input data,

compares output data, and sends copies of analog input data to each Main Processor. The Main Processors execute the userwritten

application and send outputs generated by the application to the output modules. In addition to voting the input data, the TriBus votes the output data.

This is done on the output modules as close to the field as possible, in order to detect and compensate for any

errors that could occur between the Tricon voting and the final output driven to the field.
