YOKOGAWA NFCP502-W05 CPU Processors Module
Configured for real-time control execution and network communication in STARDOM FCN autonomous controllers, the Yokogawa NFCP502-W05 (NFCP502 CPU Module) provides direct physical/electrical execution. It processes control logic on an Atom E3815 1.46 GHz processor while coordinating high-speed data transfer across four onboard Gigabit Ethernet interfaces and a redundant SB backplane bus.

4-20 mA HART Loop Protocol & Channel-to-Channel Isolation
The NFCP502-W05 manages high-density data exchanges with field I/O modules over the internal SB bus while isolating control processing logic from field disturbances. The controller coordinates analog data processing from connected 4-20 mA HART I/O channels, executing signal validation and loop control routines without introducing backplane latency. Internal isolation barriers across the backplane interface prevent field-side common-mode noise and ground loops from affecting processor stability or corrupting data held in the battery-backed Static RAM.
Frequently Asked Questions
Q: How is non-volatile user data preserved in the event of a main power failure?
A: The NFCP502-W05 retains critical process parameters and system logs within 2 MB of ECC Static RAM backed by an internal 1000 mAh graphite fluoride lithium battery, alongside 1 GB of on-board secondary flash memory.
Q: What network topologies are supported by the four onboard Ethernet ports?
A: The four RJ45 Gigabit Ethernet ports (10/100/1000 Mbps) can be configured for independent network segments or redundant network paths to support deterministic system communications and remote access.
Field Installation Guidelines
- Ensure the node rack is fully power-isolated and grounded to a dedicated low-impedance earthing bar before inserting the NFCP502-W05 into its master CPU slot.
- Align the module with the guide rails and press firmly until the backplane connectors fully seat, then tighten the retaining screws to lock the unit in place.
- Use shielded Category 5e or higher Ethernet cables for all 1000BASE-T network connections, ensuring cable shields are grounded at the cabinet entry point.
