TRICONEX D06603 central processing unit
Product Description：
A TRICONEX CPU module consists of three identical, independent processing channels that execute the same control program in parallel. Each channel has its own hardware and software, and they constantly cross-verify results using a proprietary high-speed bus system called the TriBus. This 2-out-of-3 (2oo3) voting mechanism ensures that if one channel fails or produces an incorrect result, the other two healthy channels will override it, preventing process interruptions and maintaining safety integrity.
The CPU is responsible for:
- Executing pre-programmed safety logic and control algorithms.
- Processing sensor data from input modules.
- Initiating control actions to output modules.
- Performing extensive self-diagnostics to detect faults.
- Managing communication with other modules and external systems.
Product Parameters (Typical)
Parameters can vary significantly between different Triconex CPU models (e.g., Triconex 3008, 3009, 3101, Tricon CX series), but common characteristics include:
- Architecture: Triple Modular Redundant (TMR) for fault tolerance.
- Processor: Typically a 32-bit microprocessor (e.g., Motorola MPC860 in older models), with modern versions featuring enhanced processing power.
- Clock Speed: Varies by model (e.g., 50 MHz for older models, higher for newer).
- Memory:
- DRAM: For program execution and SOE (Sequence of Events) data (e.g., 16 MB).
- Flash PROM: For storing system firmware and user applications (e.g., 6 MB, CRC-protected).
- NVRAM: For reserved variables (e.g., 8 KB, CRC-protected).
- Communication:
- TriBus for internal module communication.
- External communication ports (e.g., Ethernet, serial) for integration with DCS, SCADA, HMIs, and other systems via dedicated communication modules.
- Power Consumption: Typically low, designed for industrial 24 VDC systems (e.g., max 8 W).
- Operating Temperature: Wide range, usually from -40°C to +70°C (-40°F to +158°F).
- Humidity: 5% to 95% RH (non-condensing).
- Certifications: Typically certified to international safety standards like IEC 61508 (SIL 3) and IEC 61511.
Product Advantages
- Superior Fault Tolerance (TMR): This is the paramount advantage. The TMR architecture eliminates single points of failure, ensuring continuous, error-free operation even if a hardware component fails in one of the three channels. This maximizes system availability and prevents nuisance trips.
- High Integrity and Safety: Designed specifically for Safety Instrumented Systems (SIS), Triconex CPUs meet the highest safety integrity levels (SIL 3), crucial for protecting personnel, assets, and the environment.
- Online Repair and Maintenance: Faulty modules can be detected, diagnosed, and replaced online without interrupting the process, significantly reducing downtime.
- Comprehensive Diagnostics: Extensive self-diagnostics continuously monitor the health of the entire system, from processors to I/O, providing immediate fault detection and reporting.
- Deterministic Operation: Ensures fast and predictable execution of safety logic, providing a prompt response to process upsets.
- Simplified User Experience: From the user's perspective, the TMR system operates as a single control system, simplifying programming and operation despite the underlying triplication.
- Robustness: Built for harsh industrial environments, offering high reliability and durability.
Precautions
- ESD (Electrostatic Discharge) Protection: Always follow proper ESD handling procedures when installing or replacing modules to prevent damage.
- Compatibility: Ensure the CPU module is compatible with the specific Triconex chassis, I/O modules, power supplies, and software versions being used. Outdated MPMs may not be suitable for newer systems.
- Proper Installation: Securely install modules into the chassis slots. Offset backplane connectors and keys typically prevent incorrect insertion.
- Power Requirements: Verify that the power supply meets the specific voltage and current requirements of the CPU and the entire system.
- Firmware Updates: Firmware updates are tightly controlled due to the system's safety-critical role. Follow strict procedures and validation checks to prevent unauthorized or accidental changes that could compromise safety.
- Cybersecurity: Implement robust cybersecurity measures, especially when the system is connected to external networks. Physical key locks on main chassis often control operating modes (e.g., "PROGRAM" mode allows changes), which must be managed carefully.
- Environmental Limits: Operate the system within the specified temperature, humidity, and vibration limits to ensure long-term reliability.
Product Applications
TRICONEX Central Processing Units are indispensable in industries requiring the highest levels of safety and availability for critical control and emergency shutdown applications. They are used in:
- Oil and Gas (Upstream, Midstream, Downstream): Emergency Shutdown Systems (ESD), Fire and Gas (F&G) systems, Burner Management Systems (BMS), turbomachinery control and protection (TMC) in refineries, petrochemical plants, and offshore platforms.
- Chemical and Petrochemical: Safety shutdown, process interlocks, and critical control for hazardous processes.
- Power Generation: Boiler flame safety, turbine control and protection, critical balance-of-plant controls in fossil fuel and nuclear power plants.
- Mining and Metals: Safety interlocks for heavy machinery and hazardous processes.
- Pharmaceutical: Critical process control and safety systems for pharmaceutical manufacturing.
- Water and Wastewater: Safety monitoring and control for critical infrastructure.
