Description
Product Overview
The Yokogawa NFCP100-S00 is a central processing module for the STARDOM Field Control Node (FCN) autonomous controller platform. It provides the processing capability required to execute industrial control applications, manage connected I/O resources, and exchange data with supervisory systems and other automation equipment. Within an FCN installation, the CPU module performs the main control tasks and coordinates communication between the controller and its associated field I/O architecture. Its modular design supports distributed control applications where processing and I/O resources are installed close to the equipment being monitored or controlled.
The NFCP100-S00 uses an MMX Pentium processor operating at 166 MHz. Its memory architecture includes 128 MB of main memory with ECC functionality and 1 MB of battery-backed retentive memory, also with ECC. For external communication, the module provides two 10/100 Mbps Ethernet interfaces and one RS-232-C serial port using a 9-pin D-sub connector. The dual-redundant SB bus provides the internal I/O interface. Yokogawa’s documentation also identifies reliability, availability, and serviceability functions such as watchdog monitoring and temperature supervision.
For maintenance teams, the Yokogawa NFCP100-S00 is relevant when maintaining an existing FCN controller installation or replacing a failed CPU module. Correct identification is essential because the NFCP100 family includes different suffix options, including general-purpose and coated versions. The -S00 designation should be checked against the installed module’s nameplate and hardware revision. Before replacement, preserve the controller application, verify the system-card contents, confirm the SB bus configuration, and record the Ethernet and serial communication settings. A replacement CPU should be validated against the existing FCN hardware and software configuration before the controller is returned to service.
Product Introduction (Non-Templated)
A controller CPU replacement can affect more than application execution. Retentive data, system-card contents, network addressing, and I/O bus configuration all influence whether an FCN node can return to its previous operating state.
The NFCP100-S00 provides the processing and communication functions for Yokogawa’s FCN platform. During maintenance, preserve the original system card and application backup, and verify the module suffix and revision before installing replacement hardware.

Frequently Asked Questions
Q1: What is thawa used for?
The is the CPU module of a Yokogawa STARDOM FCN autonomous controller. It executes control applications, manages connected I/O resources, and communicates with other automation equipment.
Q2: How many Ethernet portthe have?
It has two 10/100 Mbps Ethernet ports using RJ-45 connectors. These interfaces support communication with supervisory systems and other networked devices according to the controller configuration.
Q3: Can I hothe while the controller is running?
Do not assume that live CPU replacement is permitted. The CPU is central to controller execution, and removing it may interrupt control operations. Follow Yokogawa’s approved FCN maintenance procedure and establish a safe process state before replacement.
Q4the support firmware v3.1?
Compatibility cannot be determined from the hardware part number alone. Verify the FCN system software release, CPU hardware revision, application runtime, and engineering-tool version against Yokogawa’s compatibility documentation.
Q5: Can I an with an S2 or S3 version?
Do not assume that the suffix variants are interchangeable. Compare the complete model code, hardware revision, system software requirements, and installed FCN configuration. Confirm the approved replacement combination before installation.
Q6: What should I check before installing a replacement CPU?
Back up the application and system-card contents. Record network addresses, serial communication parameters, controller settings, and I/O configuration. Inspect the base-unit connector and SB bus, and check the backup battery condition.
Q7: What are the main s an CPU failure?
Possible indicators include abnormal CPU status LEDs, watchdog events, controller startup failures, communication loss, or unexpected controller resets. Check the power supply, base-unit connection, system card, and diagnostic records before concluding that the CPU itself has failed.
ProcurementThe is a legacy FCN CPU module. The official specification identifies its processor, memory, interfaces, and electrical requirements. Before purchasing a replacement, confirm the hardware suffix, system software compatibility, battery condition, and application backup. Do not rely solely on a seller’s generic description.
