Yokogawa F3LC11-1F FA-M3 Personal Computer Link Module

Product Overview

The Yokogawa F3LC11-1F functions as a high-speed communication gateway between FA-M3 series PLCs and external personal computers or workstations. This Personal Computer Link Module enables seamless data exchange, system monitoring, and parameter adjustment via the EIA RS-232-C standard. We supply this unit as 100% Brand New and Original, ensuring your control system maintains a stable, high-fidelity serial link without the timing inconsistencies of used or refurbished hardware.

Technical Specifications

Engineering Advantages

• High-Speed Data Throughput: The F3LC11-1F supports transmission speeds up to 115.2 kbps. This capability allows for rapid data logging and real-time visualization on the host PC, minimizing the latency between field signal changes and operator screen updates.

• Simplified Command Logic: The module manages the RS-232-C control lines (RS/ER) in an "always on" state. This simplifies the handshake configuration, allowing engineers to establish a stable connection with external devices using minimal cabling complexity.

• Compact Integration: At only 2.89 cm wide, this module maximizes rack density within the FA-M3 chassis. The lightweight 0.11 kg design reduces mechanical stress on the backplane, making it ideal for mobile control skids or high-density enclosures.

• Reliable Data Integrity: Integrated parity checks and checksum calculations verify every data packet. This internal error detection ensures that electromagnetic noise does not corrupt critical control parameters during transmission between the PLC and the PC.

FAQs

• Can the F3LC11-1F operate in full-duplex mode? No. This module utilizes a half-duplex transmission mode. Ensure your host PC communication software supports half-duplex timing to prevent data collisions on the RS-232-C line.

• What is the maximum cable length for a stable connection? The EIA RS-232-C standard limits the transmission distance to 15 meters. For applications exceeding this range, you must use a signal repeater or convert the link to a different protocol such as RS-422 or Ethernet.

• Does this module provide electrical isolation? The F3LC11-1F is a non-isolated module. To protect the PLC from ground potential differences or surges in harsh environments, we recommend using an external opto-isolator on the RS-232-C line.

• Is the D-sub 9-pin connector compatible with standard PC serial cables? The module features a female D-sub 9-pin connector with M2.6 screw threads. Verify that your cable uses the corresponding M2.6 screws rather than the standard UNC 4-40 screws typically found on office PC hardware to ensure a secure mechanical lock.
