FAQs
Q1: What is the primary function of the FC-QPP-0002?
It is the central processing unit for the Honeywell Safety Manager system. It reads field I/O signals, executes safety logic created in graphical Functional Logic Diagrams (FLDs), and transmits results to output interfaces. Continuous testing by the QPP-0002 ensures safe process control and provides extensive system and equipment diagnostics.
Q2: What is the difference between FC-QPP-0002 and FC-QPP-0001?
The FC-QPP-0002 is the second-generation (enhanced performance) Quad Processor Pack. It is backward compatible with the QPP-0001 and serves as a one-on-one drop-in replacement when the Safety Manager is running firmware R121 or higher.
Q3: What is the voting architecture of the FC-QPP-0002?
In a non-redundant Controller, one QPP-0002 module operates with 1oo2D functionality (dual processors with hardware data comparators). In a redundant Controller, two QPP-0002 modules form a 2oo4D voting architecture, providing the highest level of fault tolerance for SIL 3 applications.
Q4: Can the FC-QPP-0002 be hot-swapped?
Only when the key switch is in STOP position. The module can be safely removed or replaced only when the key switch is set to STOP. In redundant configurations, the replacement module synchronizes and copies the application logic across the redundant communication link. In non-redundant systems, the application file must be reloaded via Safety Builder software.
Q5: What firmware version is required for compatibility?
The FC-QPP-0002 requires Safety Manager firmware R121 or higher for seamless drop-in replacement of the QPP-0001. Major firmware revision mismatches can lead to communication link timeouts or FLD execution halts. Always confirm that the system software build in the Safety Builder utility matches the target processor build version.
