TRICONEX CPU 3008 Central unit
Product Description:
The TRICONEX Central Unit, often referred to as the main processor or controller, forms the heart of a Triconex Safety Instrumented System (SIS). It is built upon a Triple-Modular Redundant (TMR) architecture, integrating three isolated, parallel control systems within a single unit. This architecture, combined with extensive diagnostics and a voting mechanism, allows the system to identify and compensate for failed elements, ensuring high integrity, error-free, and uninterrupted process operation.
Key Functions
- Triple Modular Redundancy (TMR): Executes the control program independently across three identical channels, with two-out-of-three voting to ensure high integrity and uninterrupted operation.
- Fault Tolerance: Continuously monitors for faults and can operate with one or even two failures in its channels without process interruption.
- High-Integrity Diagnostics: Provides comprehensive system diagnostics that immediately detect and report operational faults.
- Safety Logic Execution: Processes sensor data, executes pre-programmed safety logic to identify hazardous situations, and initiates control actions to prevent accidents or equipment damage.
- Communication & Integration: Supports various communication protocols for integration with Distributed Control Systems (DCSs), SCADA, HMIs, and other plant automation systems.
Product Parameters (Typical for Tricon CX)
- I/O Capacity: Capable of handling a large number of I/O racks and modules, supporting a high volume of physical I/Os (e.g., up to 15 I/O racks, 90 I/O modules, and 2,800 physical I/Os per controller).
- Network Scalability: Up to 254 nodes can be networked in a single peer-to-peer network, managing in excess of 750,000 physical TMR I/Os.
- Scan Times: Fast scan times, typically from 20 milliseconds.
- Event Storage: Can store up to 60,000 Sequence of Events (SOEs) per controller, time-stamped at 1 millisecond at the I/O module.
- Safety Integrity Level (SIL): Certified by TÜV Rheinland to Safety Integrity Level 3 (SIL3), even under fault conditions.
- Module Replacement: Processor, communication, and I/O modules can be replaced online without halting operations.
Product Advantages
- Superior Safety and Reliability: The TMR architecture provides unmatched fault tolerance, ensuring continuous protection for safety-critical units and minimizing the risk of unscheduled outages and dangerous nuisance trips.
- High Availability and Uptime: Designed for continuous operation, leading to superior plant uptime and high productivity.
- High Performance and Capacity: Offers high-capacity handling for a vast number of I/O channels and fast scan times.
- Ease of Use and Maintenance: Engineered for superior ease of use, simplifying engineering, installation, configuration, operation, and maintenance, which reduces overall expenditures.
- Flexible Integration: Universal connectivity with all major DCSs, process automation systems, SCADA, and HMI.
- Online Maintenance: Modules can be replaced online (hot-swapped) without interrupting the controlled process.
Precautions
- Compatibility: Ensure compatibility between the central unit and all other system components, including I/O modules, communication modules, and termination devices.
- Installation Environment: Maintain proper environmental conditions, including temperature and humidity, as specified in the product documentation. Adequate ventilation for enclosures is crucial.
- ESD Protection: Handle modules with care to prevent damage from electrostatic discharge (ESD).
- Proper Wiring: Adhere strictly to wiring guidelines to prevent electrical noise, ensure signal integrity, and avoid damage.
- Configuration Accuracy: Accurate configuration of all parameters and safety logic is paramount for safe and correct operation.
- Enclosure and Physical Protection: Central units are often housed in robust enclosures (e.g., K62, K72, G60) that provide environmental protection. Ensure these enclosures are properly maintained and provide adequate ventilation.
- Documentation: Always refer to the official TRICONEX (now Schneider Electric) planning, installation, and safety considerations guides for detailed instructions and precautions.
Product Applications
TRICONEX Central Units are specifically designed for safety and critical control applications across various demanding industries due to their high integrity and fault tolerance.
- Emergency Shutdown (ESD) Systems: Crucial for immediate and safe shutdown of processes in hazardous situations (e.g., in refineries, petrochemical/chemical plants).
- Burner Management Systems (BMS): Ensuring safe startup, operation, and shutdown of industrial burners.
- Turbomachinery Control and Protection (TMC): For controlling and protecting turbines and compressors.
- Fire and Gas (F&G) Systems: Detecting fire and gas leaks and initiating appropriate safety responses.
- High-Integrity Pressure Protection Systems (HIPPS): Preventing overpressure in pipelines and vessels.
