System Role (Important)

The NFCP502-W05 acts as the core controller of a Field Control Node (FCN):

• Executes control logic (PID, sequencing, interlocks)
• Collects and processes I/O data
• Communicates with upper-level DCS systems (CENTUM VP)
• Handles local autonomous control when disconnected from host

Advantages

• High reliability industrial CPU design
• Strong network capability (4 Ethernet ports)
• Suitable for distributed / remote control systems
• Stable long-term operation in harsh environments
• Flexible storage and communication expansion
• Widely used in Yokogawa STARDOM architecture worldwide

Precautions

• Must be used in compatible Yokogawa FCN/STARDOM system
• Requires correct 5V regulated power supply
• Ensure proper SD card compatibility (industrial grade recommended)
• Battery-backed SRAM requires periodic battery maintenance
• Firmware version must match system configuration
