The Tricon controller is a state-of-the-art programmable logic and process controller that provides a high level of system fault tolerance. To ensure the highest possible
• 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. ible system integrity at all times, the Tricon controller includes these features:
• 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.
Fault Tolerance:
Fault tolerance, the most important capability of the Tricon controller, is the ability to detect transient and steady-state error conditions and to take appropriate corrective action online. With fault tolerance, there is an increase in safety and an increase in the availability of the controller and the process being controlled.
The Tricon controller provides fault tolerance through Triple Modular Redundant (TMR) architecture. The controller consists of three identical system channels, except for the Power Module,e which are dual-redundant. Each channel independently executes the control program (also referred to as the TriStation application) in parallel with the other two channels. Hardware voting mechanisms qualify and verify all digital inputs and outputs from the field; analog inputs are subject to a mid-value selection process.
