NFCP100-S05 S3 YOKOGAWA Processor Module

The NFCP100‑S05 S3 is a CPU (processor) module produced by Yokogawa Electric Corporation, part of their “FCN‑100 / STARDOM” family of autonomous controllers

(Field Control Node).It integrates a CPU with ECC (Error‑Correcting Code) memory, which enhances reliability by detecting/correcting memory

errors — important for industrial automation and control systems.It is designed for high performance, reliability, and scalability: suitable

for real‑time control, data acquisition, and robust industrial environments.The module is built to support duplexing — meaning

CPU, power supply, and control network can be duplexed (redundant configuration) to increase fault tolerance and uptime.

It features low heat dissipation, eliminating the need for a cooling fan — beneficial for

long-term reliability and simpler installation/maintenance.

Frequently Asked Questions

What does “S3” mean in NFCP100-S05 S3?

“S3” is a suffix/version code for the CPU module series. It denotes a version/variant of the NFCP100‑S05 module. (Suffix codes are

part of how Yokogawa tracks revisions or variants.)

Is the CPU module hot‑swappable or redundant?

Yes — the design of FCN allows CPU module, power supply, and bus network to be duplexed (redundant), and modules are

hot‑swappable for maintenance without shutting down the entire system.

What kind of applications is it good for?

Industrial automation, process control, distributed control systems (DCS), environments requiring high reliability, fault

tolerance, modular I/O, redundant architecture, and long-term

stable operation.
