TRICONEX 2101

Description

TRICONEX 2101
To ensure the highest possible system integrity at all times, the Trident controllerincludes the following features:Trident Planning and Installation Guide• Provides Triple Modular Redundant (TMR) architecture, whereby each ofthree identical channels independently executes the application, andspecialized hardware and software mechanisms vote all inputs and outputs.• Withstands harsh industrial environments.• Integrates the I⁄O module with the termination assembly.• Enables field installation and repair to be done at the module level while thecontroller remains online without disturbing field wiring.• Supports up to 14 I⁄O modules. (If the controller includes AO or PIModules, up to 10 modules are supported.)• Provides TriStation and Modbus communication directly from the MainProcessor (MP) or from the Communication Module (CM).• Executes applications developed and debugged using TriStation.• Provides a dedicated co-processor which controls the input and outputmodules to reduce the workload of the MP. Each I⁄O module is supported bycustom application-specific integrated circuits (ASICs), which scan inputsand perform diagnostics to detect hardware faults. Output module ASICs dothe following:– Supply information for voting of output data.– Check I⁄O loop-back data from the output terminal for final validation ofthe output state.– Perform diagnostics to detect hardware and field-wiring problems.• Provides integral online diagnostics with adaptive-repair capabilities.• Allows normal maintenance while the controller is operating, withoutdisturbing the controlled process.• Supports hot-spare I⁄O modules for critical applications for which promptservice may not be possible.• Provides integral support for redundant field and logic power sources‘
