Module Functional Overview

The F3RS41-0N is a high-performance serial interface module developed for the Yokogawa FA-M3 Range-free multi-controller series. It provides a reliable RS-232C communication channel between the PLC CPU and external devices such as barcode readers, printers, HMI terminals, weighing scales, and third-party controllers.

Optimized for low-latency data transmission, the module supports high baud rates and flexible framing configurations. It is particularly suitable for legacy system integration and localized point-to-point serial communication within industrial automation environments.

Detailed Technical Specifications

Industrial Application Context

Peripheral Integration
Direct connection of industrial scanners, weighing scales, label printers, or operator terminals to the PLC CPU.

Legacy System Bridging
Reliable interfacing with CNC machinery, analyzers, or other legacy equipment using serial communication protocols.

Diagnostic and Data Logging
Transmission of production data, alarm logs, or batch records to serial printers or monitoring devices.

Engineering FAQ

How does the F3RS41-0N differ from the F3RS21?
The F3RS21 is a dual-port RS-232C module, whereas the F3RS41-0N is a single-port high-speed variant optimized for FA-M3 systems, featuring enhanced buffer management for improved reliability at higher baud rates.

Does this module require external power?
No. The F3RS41-0N draws approximately 150 mA at 5 V DC directly from the FA-M3 backplane, eliminating the need for separate external power wiring.

Is a specific cable required for connection?
A standard 9-pin D-sub (female) RS-232C cable is typically used. Depending on handshake requirements, custom wiring of RTS/CTS lines may be necessary for third-party device compatibility.
