Yokogawa F3LC11-1F Personal Computer Link Module

The Yokogawa F3LC11-1F, also cataloged as the F3LC11 Personal Computer Link Module, operates as a dedicated hardware component for industrial controls and communications within FA-M3 and STARDOM controller networks. Configured for serial interface execution, the module executes point-to-point asynchronous data exchanges to link host computer applications directly with the internal controller register space.

Industrial Control & Communications Technical Attributes

This communication module relies on a deterministic serial interface driver capable of scaling data transmission velocities up to 115.2 kbps over a 15 m physical copper link. The D-sub interface handles asynchronous character streaming, using automatic hardware parity generation and checksum validation blocks to enforce communication link velocity parameters. Because the port utilizes a non-isolated architecture directly tied to the internal backplane ground plane, all connected host hardware must share an identical potential baseline to prevent cross-talk noise interference or transient voltage breakdown across the serial logic channels.

Frequently Asked Questions

Q: Why are the RS (Request to Send) and ER (Data Terminal Ready) lines hardwired to an always-on state inside this module?

A: The module forces these control loops active to skip complex hardware handshaking timing routines, allowing instant, half-duplex start-stop synchronization over basic three-wire RS-232-C serial cables.

Q: What precautions must be taken due to the non-isolated design of the F3LC11-1F serial port?

A: Ground loop currents will travel through the communication cable if the host PC and the controller rack operate at different ground potentials; you must maintain equipotential grounding or insert an external isolation barrier.

Field Installation Guidelines

Baseplate Module Engagement: Align the card chassis with the dedicated slot guides on the controller baseplate, sliding it until the backplane interface seats completely before fastening the retention screw.
Serial Cable Torque: Secure the female D-sub 9-pin cable connector onto the module faceplate interface using the M2.6 terminal retention screws to prevent vibration-induced disconnects.
Equipotential Bonding Trace: Connect the host computer frame ground and the controller baseplate rack directly to a centralized clean earth ground bar to avoid stray common-mode potential differences.
Baud Rate Matching Configuration: Verify that the software registers inside the CPU configuration tool exactly match the external host computer system velocity settings (up to 115.2 kbps) to avoid frame errors.
