Product Description

The F3LC11-2N is a high-efficiency PC Link communication interface module designed specifically for the Yokogawa FA-M3 PLC series. This module enables fast and reliable data exchange between programmable logic controllers and supervisory systems such as industrial PCs and HMI/SCADA stations. By providing transparent access to internal PLC memory and device registers, it simplifies system integration, reduces development complexity, and shortens deployment and maintenance time.

Designed for scalable automation architectures, the F3LC11-2N supports multi-drop networking, allowing up to 32 FA-M3 PLC units to be connected via RS-422-A/RS-485 communication. The module also supports remote control operations such as RUN/STOP commands, program upload/download, and diagnostic log retrieval, making it highly suitable for centralized automation management. Its compact design allows flexible installation in modern control panels using DIN rail or panel mounting methods.

Detailed Technical Specifications

Application

• Centralized Monitoring: Aggregates operational data from multiple FA-M3 controllers into SCADA or supervisory systems.

• Remote Maintenance: Enables remote programming, debugging, and system log analysis without direct PLC connection.

• Distributed Manufacturing Control: Supports coordinated automation between multiple controllers in production cells.

• Industrial Data Integration: Facilitates real-time data acquisition for process optimization and monitoring.

Technical FAQ

Do I need custom programming to use this module?
No. The F3LC11-2N uses the standard PC Link communication protocol, allowing users to perform memory read/write operations using standard commands without custom communication programming.

Can RS-232 and RS-422 be used simultaneously?
Both interfaces are available physically, but their usage differs. The RS-232-C port is typically used for point-to-point PC communication, while the RS-422-A/485 port is required for multi-drop networking with up to 32 PLCs.
