The QPP-0002 is a high-performance processing module designed for use within Safety Manager systems. It plays a critical role in controlling and managing all system operations, ensuring safe process control and system diagnostics.
Features
Dual Processors: The QPP-0002 module features two processors running synchronously, allowing for robust data processing and redundancy. In a redundant controller configuration, the two processors synchronize via a dedicated communication link.
Memory:
2 × 2 MB Flash memory for storing the system and application programs.
2 × 256 KB SRAM (battery-backed) for I/O, markers, counters, timers, and registers.
2 × 512 KB SRAM for data exchange with the other Control Processor.
1 × 16 MB Flash memory for backup purposes.
Redundancy Support: In a redundant Controller setup, two QPP-0002 modules are installed, operating in a 2oo4D voting architecture to ensure fault tolerance and high reliability.
Diagnostics and Self-testing: The module includes extensive self-tests and diagnostic routines, ensuring that hardware faults are detected early. The QPP-0002 provides higher than 99% diagnostic coverage, making it suitable for SIL3 applications.
Watchdog Mechanism: Includes a fully testable watchdog that monitors processor performance, ensuring the system remains operational in the event of failure.
Temperature Monitoring: Monitors the internal temperature to prevent overheating and ensure stable operation.
Real-Time Clock: Ensures time-sensitive operations are accurate and consistent across the system.
Performance and Safety
The QPP-0002 module is designed to run applications up to and including SIL3 (Safety Integrity Level 3) without time limitations, making it suitable for high-risk and safety-critical applications.
Data Comparators: Continuous comparison of every read and write action by the processors ensures that the system remains in sync, and any discrepancies trigger a safety shutdown.
Backup and Flash Memory: Flash contents can be updated while the module is still installed in the controller chassis, allowing for convenient maintenance and updates.
User Interface and Control
Processor Status Key Switch: Enables safe control over the processor operation, including STOP, start, reset, and power-up/down functions.
Status LED: Provides visual indicators for processor health and system status.
User Interface Display: Allows easy monitoring and control of the system's status and performance.
