The Yokogawa NFCP502-W05, also cataloged as the NFCP502 CPU Module, operates as a dedicated hardware component for deterministic process regulation and autonomous logic execution within STARDOM control system architectures.

Suffix Breakdown & Model Matrix

• NFCP502: Base model series for high-performance STARDOM autonomous controllers.
• W05: Denotes hardware revision and specific interface configuration for Ethernet and serial communication integration.

Hardware Specifications

Process Control and System Integrity

The NFCP502-W05 is engineered to execute complex control algorithms while maintaining high-speed communication across industrial Ethernet networks. The module utilizes ECC-protected memory for both main RAM and static RAM, ensuring data integrity during real-time processing tasks. To prevent communication errors in deterministic networks, the controller supports configurable full/half duplex operation on its four Ethernet ports. When deployed in redundant configurations, the module manages state synchronization and I/O image updates to support fail-safe state execution, maintaining system availability without manual intervention.

Frequently Asked Questions

Q: Does the NFCP502-W05 support hot-swapping during active operation?

A: No. The CPU module is a central component of the STARDOM controller rack. Power must be removed from the base plate before the module is extracted to prevent backplane bus voltage surges or data corruption.

Q: How does the module handle storage during power loss?

A: The module utilizes 2 MB of battery-backed SRAM with ECC to preserve critical process data and tags. For long-term data logging or firmware storage, the onboard SD card slot supports SDHC media (4 GB to 32 GB, Class 10).

Field Installation Guidelines

• Mounting: Ensure the module is fully inserted into the designated CPU slot of the STARDOM rack. Engage the locking levers firmly to guarantee secure connection to the backplane communication bus.
• Communication Wiring: Use shielded Cat5e or Cat6 cabling for the Ethernet ports. Terminate shields at the cabinet ground bar to minimize noise interference in high-EMI environments.
• Grounding: The module chassis must be connected to the cabinet ground bus via the rack frame. A clean ground reference is mandatory to maintain the stability of the 5 VDC power input and the integrity of serial communications.
• Thermal Management: Ensure 50 mm of clearance above and below the rack assembly. While the module is rated for up to 70 deg C, excessive internal cabinet temperatures may lead to performance throttling of the Intel Atom processor.
