Description
NFCP100-S00 S3 | Yokogawa STARDOM Field Control Processor
Dynamic Product Introduction
Unscheduled controller failures on remote terminal units usually trigger immediate plant-wide panic when remote telemetry stops updating. When an aging CPU locks up or suffers persistent watchdog faults, swapping the unit quickly becomes the only viable path to restore automation loops. Rather than upgrading the entire control rack architecture, deploying a direct-fit NFCP100-S00 S3 processor re-establishes local logic execution and network communications instantly.
The NFCP100-S00 S3 functions as the central intelligence node for Yokogawa STARDOM field control stations. Built for harsh remote environments, it executes user-defined control programs while managing I/O scan cycles and upstream SCADA telemetry without skipping a beat.

Global Sourcing & Live-Test SOP (Transparency Core)
To guarantee reliability when deploying surplus or replacement processor units, every item undergoes a rigorous validation process prior to shipment.
1.Inbound Anti-Counterfeit & Visual Inspection：Prerequisite。
Examine serial labels, batch tracking codes, and housing integrity against factory records. Inspect gold-plated backplane connector pins for oxidation or bending.
2.Bench Power Boot Sequence：5 min。
Mount the NFCP100-S00 S3 onto a test node rack powered by a regulated 24 V DC supply. Verify normal power-up sequences and CPU readiness status.
3.Firmware & Communication Handshake Test：20 min。
Establish a direct Ethernet link using engineering software. Verify firmware stability, test memory read/write cycles, and validate dual port network communication integrity.
4.Thermal Soak & ESD Packaging：24 Hours。
Run the processor under full operational load inside an environmental testing chamber at 45°C for 24 hours. Seal the unit in an anti-static bag with desiccant upon passing.
The Field Engineer’s Pitfall Guide
Critical Installation Warnings
Verify firmware revisions, battery backup states, and network IP parameters carefully before replacing active controllers.
❗ 1. Firmware Revision Mismatch with Existing I/O Modules
—Dropping a replacement NFCP100-S00 S3 with a newer or older firmware revision into an existing rack can cause communication timeouts if the I/O module definitions do not match the system configuration file. Always back up and verify the software project version before swapping hardware.
❗ 2. Failing to Transfer or Configure NVRAM/Battery Backups
I’ve seen plants lose critical retentive data and configuration logs during a controller swap because the internal backup battery was depleted during long-term warehouse storage. Always check the battery voltage status indicator immediately upon initial power-up.
❗ 3. Overlooking Static IP and Network Parameter Defaults
A brand-new or surplus processor ships with default network settings. Connecting it directly to a live plant ring without reassigning the proper IP address and node ID will cause network address conflicts and sever SCADA connectivity.
Intent-Driven FAQ
Will swapping the NFCP100-S00 S3 erase my application control program?
It depends on the memory card configuration. User logic and programs are typically stored on an external PCMCIA/flash memory card. If you move the original memory card to the replacement unit, your program and data remain intact.
How do I check if the CPU is running normally after installation?
Monitor the status LEDs on the front faceplate. A steady green RUN light combined with extinguished error indicators confirms that the processor has successfully booted and is executing control logic.
Can I hot-swap this processor module in an active rack?
Hot-swapping CPU modules in a non-redundant rack will drop control and communication across all connected loops. Only perform swaps during a scheduled maintenance window unless your hardware is configured in a fully redundant pair.
What engineering software is required to connect to this controller?
Yokogawa’s STARDOM engineering toolset (such as FAST/TOOLS or Resource Manager / Logic Designer) is required to download configurations, monitor variables, and diagnose system errors.
What is covered under the replacement hardware warranty?
Standard procurement warranties cover functional performance, internal component stability, and communication port integrity for 12 months from the date of delivery.
