Yokogawa FA-M3 Series Personal Computer Link Module

Product Overview

The Yokogawa F3LC11-1F is a Personal Computer Link Module for the FA-M3 series, providing RS-232C serial communication between FA-M3 PLCs and personal computers, FA computers, or displays. It enables direct data read/write, ladder program upload/download, run/stop control, and error history retrieval without requiring a dedicated transmission application program. The D-sub 9-pin connector supports half-duplex transmission up to 15 meters.

Compatibility & Applications

Compatible with all FA-M3 CPU modules and base units. Essential for programming and maintenance via PC, HMI display connection, data acquisition systems, remote diagnostics via modem, and laboratory/test bench automation requiring direct serial communication.

FAQ

• Q: Can I connect directly to a PC without a hub? A: Yes, use a standard RS-232C cross cable (null modem) for direct PC-to-PLC connection.
• Q: What is the maximum cable length? A: 15 meters maximum for reliable RS-232C communication.
• Q: Can I use this with a modem for remote access? A: Yes, connect a modem or terminal adapter using a straight-through RS-232C cable for remote dial-up access.
• Q: Is special software required? A: Yokogawa WideField3 programming software supports direct communication via F3LC11-1F.

Installation Guide

1. Power off the FA-M3 system.
2. Insert F3LC11-1F into any available I/O slot.
3. Connect RS-232C cable (cross cable for direct PC, straight for modem) to the 9-pin D-sub connector.
4. Configure communication parameters (baud rate, data bits, parity) in WideField3 to match module settings.
5. Restore power and establish communication test from PC.
6. Verify program upload/download functionality before production use.

Selection Tips

• Use F3LC11-1F for RS-232C programming and maintenance access to FA-M3 systems.
• For RS-422/485 multi-drop networks, consider F3LC11-2N or F3LC12-1F.
• For Ethernet connectivity, use F3LE12-0T or F3LE01-5T instead.
• Keep cable runs under 15 meters; use RS-422/485 or Ethernet for longer distances.
