HONEYWELL QPP-0002 Quad Processor Pack

The QPP-0002 (Quad Processor Pack) is the second-generation processing module for Safety Manager systems. It plays a central role in controlling all system operations, handling input signals, executing user-defined control logic, and ensuring safe system functionality. This module is designed for use in Controller chassis and is a critical component in both non-redundant and redundant controller configurations.

Key Features:

• Dual Processors: Two processors run synchronously for enhanced system performance, ensuring continuous control and diagnostics.
• Redundant Communication Link: In redundant configurations, the two QPP-0002 modules synchronize through a dedicated link.
• Fault Detection and Diagnostics: Extensive diagnostic coverage (greater than 99%), including watchdog functionality, temperature monitoring, memory error handling, and real-time clock.
• SIL3 Certification: The QPP-0002 can run applications up to SIL3 (Safety Integrity Level 3) without time limitations in a redundant controller configuration.
• 1oo2D Voting Architecture: Redundant configuration results in a 2oo4D (two-out-of-four data) voting system for added safety.
• System and Application Program Flash Memory: Flash memory allows for backup and updates without module removal.

Module Components:

• Two Processors running synchronously during operation and re-synchronizing after software downloads.
• Flash Memory:
  • 2 × 2 Mbyte for system and application programs.
  • 1 × 16 Mbyte for program backup.
• RAM:
  • 2 × 256 kbyte SRAM (battery-backed) for IO, markers, counters, timers, and registers.
  • 2 × 512 kbyte SRAM for data exchange with the redundant control processor.
• Watchdog and Monitoring:
  • Watchdog with minimum/maximum execution time monitoring and memory error handling.
  • 24V and 5V monitoring for power supply health.
• Emergency Shut Down Input: A dedicated 24V input for emergency shutdown scenarios.
• Output Features:
  • Two outputs for non-redundant or redundant I/O.
  • Four IObus drivers.
• Diagnostics and Temperature Monitors: Ensures that the system operates within safe parameters.
