The Tricon is a state-of-the art

controller that provides fault tolerance

by means of Triple-Modular Redundant

(TMR) architecture. TMR integrates

three isolated, parallel control systems

and extensive diagnostics in one control

system. The system uses two-out-ofthree

voting to provide high-integrity,

error-free, uninterrupted process operation

with no single point of failure.

The Tricon controller uses three identical

channels. Each channel independently

executes the control program in

parallel with the other two channels.

Specialized hardware/software voting

mechanisms qualify and verify all

digital inputs and outputs from the

field, while analog inputs are subject to

a mid-value selection process.

Because each channel is isolated from

the others, no single-point failure in any

channel can pass to another. If a hardware

failure does occur on one channel,

the other channels override it. Meanwhile

the faulting module can easily be

removed and replaced while the

controller is online without interrupting

the process.

Setting up control programs is simplified

with the triplicated Tricon system,

because it operates as a single control

system from the user’s point of view.

The user terminates sensors and actuators

at a single wiring terminal and 

programs the Tricon with one set of

control program logic. The Tricon

controller manages the rest!
