Overview
Configured for dual-processor synchronization, memory diagnostics, execution-time monitoring, and 1oo2D safety logic, the Honeywell FC-QPP-0002 (FC-QPP-0002 Quad Processor Pack) provides processor-level monitoring and redundant I/O interface functions within a Honeywell safety control architecture. It uses flash memory for system and application programs and battery-backed RAM for retained processor data.

Dual-Processor Safety Monitoring
The FC-QPP-0002 uses two synchronous processors to execute the control application and compare processor and memory data. Data comparators detect discrepancies between the processor paths and their associated memory areas.
The module also monitors processor execution time. Minimum and maximum execution-time checks provide diagnostic supervision of processor operation. When the memory system detects an error, the memory error handler manages the detected condition.
The 1oo2D architecture combines dual-channel processing with diagnostic comparison. The module also monitors both 24 V and 5 V supply conditions.
Frequently Asked Questions
Q: How does the FC-QPP-0002 monitor its two processors?
A: The module operates two synchronous processors and uses data comparators to compare processor and memory data. It also monitors minimum and maximum execution times.
Q: What memory does the FC-QPP-0002 use?
A: The module uses flash memory for system and application programs. It also uses battery-backed RAM, with the battery located in the BKM-0001.
Q: What I/O and shutdown interfaces does the module provide?
A: The module provides a 24 V emergency shutdown input and two outputs. The outputs support non-redundant or redundant I/O configurations.
Field Installation Guidelines
Install the FC-QPP-0002 according to the applicable Honeywell system hardware documentation and cabinet assembly requirements.
- Verify the module model before installation and confirm compatibility with the target chassis and system configuration.
- Check the 24 VDC and 5 VDC supply rails against the specified voltage ranges before energizing the module.
- Route power and signal wiring separately where the cabinet design permits.
- Keep emergency shutdown wiring physically separated from circuits that could introduce unwanted electrical interference.
- Use appropriate cabinet grounding and bonding practices for the installation environment.
- Maintain secure connections for processor, power, and I/O interfaces.
- Do not treat the estimated shipping dimensions as the physical module dimensions.
- Check the BKM-0001 battery arrangement when servicing the battery-backed RAM function.
- After installation, verify the processor diagnostics, supply monitoring, memory status, and I/O configuration through the applicable system commissioning procedure.
