Description
The Yokogawa NFCP502-W05 is a high-performance central processing unit (CPU) module designed for the Yokogawa FCN-500 (Field Control Node) autonomous controller and CENTUM VP distributed control system architecture.
In industrial field deployments, this module executes continuous regulatory control logic and discrete sequence control operations. It serves as the primary processing node for data acquisition, system communication, and hardware management in process automation environments such as oil, gas, power, and chemical plants.

Integration and Compatibility Notes
The NFCP502-W05 mounts into designated CPU slots on FCN-500 base modules and requires appropriate engineering software toolsets (such as Yokogawa’s CENTUM or Field Control Node programming tools) for configuration.
- Redundancy Support: Supports dual-redundant CPU and power supply configurations (when paired with a matching secondary module and duplex base rack) to ensure high availability and bumpless switchover during critical process runs.
- Battery Maintenance: Utilizes an internal graphite fluoride lithium battery (approx. 1000 mAh) to maintain static RAM data and system clock continuity during power interruptions. Verify battery status indicators prior to plant commissioning.
- Firmware and Security: Verify that controller firmware revisions align with plant network security policies and engineering station software versions before downloading configuration files.
Frequently Asked Questions
Q: What do the suffix characters “-W05” designate in the part number? A: The “-W” prefix indicates a CPU module equipped with extended software and network functions, while the trailing digits designate standard type configuration (-0) and basic safety/environmental certifications without specialized explosion-proofing options (-5).
Q: Can this CPU module operate as a standalone controller? A: Yes. The FCN-500 functions as an autonomous field controller capable of executing localized control strategies while communicating with supervisory human-machine interface (HMI) software and upper-layer plant networks via its onboard Ethernet ports.
Q: What is the purpose of the onboard SD card slot? A: The SD card slot supports removable storage media (SDHC Class 10 cards between 4 and 32 GB) used for data logging, system backups, software updates, and project file transfers.
