Product Overview
The Yokogawa F3LC11-2F is a Personal Computer Link Module designed for the FA-M3 PLC system. It enables communication between a PLC and a personal computer or FA engineering workstation using an RS-422A / RS-485 interface.
Unlike RS-232C versions, this module is designed for long-distance, multi-drop industrial communication, making it suitable for large-scale distributed control systems.

Function and Working Principle
The F3LC11-2F acts as a communication gateway module between a PLC system and a host computer.
Working Principle
- A PC or host system sends commands via RS-422A/RS-485 network
- The module receives and interprets communication frames
- Data is exchanged with FA-M3 PLC memory areas
- Responses are transmitted back to the host system
PC↔PLCFA−M3 (RS−422/RS−485)PC \leftrightarrow PLC_{FA-M3} \; (RS-422/RS-485)
Key Functions
- Enables PC-to-PLC communication over long distances
- Supports multi-drop networking (up to 32 FA-M3 stations)
- Reads and writes all PLC device memory areas
- Allows remote RUN/STOP control of PLC
- Supports program upload and download
- Enables system monitoring and diagnostics
- Works without dedicated communication application software
System Role
The module is used as a high-level communication interface in FA-M3 systems:
PC / SCADA / Engineering Station → F3LC11-2F → FA-M3 PLC network
It supports:
- Distributed control systems
