YOKOGAWA F3LC21-1N Multi-link unit

The YOKOGAWA F3LC21-1N is a high-performance Multi-Link Unit (also referred to as a Multi-Link Module) belonging to the FA-M3 (Free Application Micro Controller) series. 

It is a specialized communication interface designed to facilitate complex data exchange between multiple controllers or peripheral devices.

1. Introduction

The F3LC21-1N is a core communication module for the Yokogawa FA-M3 and FA-M3V PLC systems. Unlike a standard single-port serial link, the "Multi-Link" designation implies its ability to manage multi-point communication configurations

. It allows the FA-M3 system to interface with other PLCs, HMIs (Human Machine Interfaces), and host computers over a robust industrial network architecture.

3. Product Advantages and Features

High-Speed Data Exchange: Leverages the FA-M3's "Vitesse" engine architecture for rapid data throughput, minimizing latency in multi-node networks.

Versatile Protocol Support: Supports the Yokogawa personal computer link protocol, allowing for seamless integration with SCADA and custom software.

System Scalability: Designed to allow multiple FA-M3 racks to share data, enabling the coordination of large-scale industrial processes.

Stable Industrial Design: Features high immunity to electrical noise and a compact, fanless design suitable for DIN-rail mounting within control cabinets.

4. Application Cases

The F3LC21-1N is utilized in environments requiring coordinated automation:

Distributed Control Systems (DCS): Acting as a gateway between local FA-M3 logic and a centralized plant management system.

Large Manufacturing Lines: Synchronizing data between multiple machines (e.g., an assembly line where each station has its own PLC).

Building Automation: Monitoring and controlling HVAC, lighting, and security across large facilities by linking distributed controllers.

Semiconductor Tools: Coordinating high-speed motion and wafer tracking data between different tool modules.

5. Other Models in the Same Series

Yokogawa's FA-M3 communication family includes several variations based on speed and physical interface:

F3LC11-1F: Standard Personal Computer Link Module (RS-232-C).

F3LC11-2F: RS-422-A / RS-485 Link Module for longer distances.

F3LE11-0T: Ethernet Interface Module (10BASE-T/100BASE-TX).

F3SP21 / F3SP28: CPU Modules that integrate with these link units.

F3RS22-0N: Serial Communication Module (RS-232-C/RS-422).
