Structural Features: The ICS Triplex system comprises multiple rack types including the T8100 main controller chassis, T8240 power supply chassis, and T8300 expansion chassis. Modules plug into chassis backplanes with triplicated inter-module bus connections.
Working Principle: The ICS Triplex Trusted TMR system operates on the principle of triple modular redundancy, where three independent processors execute identical control programs simultaneously. Hardware voters compare outputs using majority agreement logic, ensuring that any single-point fault is automatically masked without interrupting process control.
Installation Requirements:
- Follow ICS Triplex system installation manuals for chassis mounting and wiring
- Ensure proper grounding and shielding throughout the installation
- Maintain environmental conditions within specified operating ranges
- Implement proper cable management and separation
Usage Notes:
- Adhere to the complete safety lifecycle including scope definition, functional requirements, system engineering, application programming, integration, installation, commissioning, verification, operation, maintenance, and modification
- Follow Management of Change (MOC) procedures for all system modifications
- Perform regular proof testing as defined by the safety requirements specification
- Maintain spare module inventory in anti-static storage
