Product Description
The NFLR121-S00 S1 is a high-performance serial communication module engineered for the Yokogawa CENTUM VP and compatible with Yokogawa CENTUM CS 3000 architectures.
It enables seamless data exchange between the Field Control Station (FCS) and external subsystem devices such as PLCs, flow computers, power monitors, and analyzers.
The module features two independent RS-232C ports, allowing separate protocol configurations within a single-slot footprint. This dual-channel design increases subsystem connectivity without requiring additional gateway hardware.
Designed for continuous industrial operation, the NFLR121-S00 S1 supports multiple baud rates and transmission modes to match diverse field equipment requirements. It integrates directly into the I/O unit nest, providing a compact and reliable subsystem communication interface.

Application and System Integration
The NFLR121-S00 S1 is primarily used for subsystem integration within distributed control environments, including:
-
PLC interfacing
-
Flow computer data acquisition
-
Power monitoring systems
-
Analyzer communication
-
Package equipment integration
By providing direct serial connectivity inside the control cabinet, it eliminates the need for standalone protocol converters, reducing system complexity and improving reliability.
Subsystem Integration FAQ
Which protocols does the NFLR121-S00 S1 support?
The module typically supports Modbus RTU (Master/Slave) and other general-purpose serial communication protocols configured through Yokogawa subsystem communication functions.
Can the NFLR121-S00 S1 be used in a redundant configuration?
Yes. In high-availability systems, dual NFLR121-S00 S1 modules can be installed in a duplexed configuration to maintain communication continuity in the event of a hardware failure.
