Description

Yokogawa F3LE01-5T Ethernet Interface Module

The Yokogawa F3LE01-5T, also cataloged as the F3LE01 Ethernet Interface Module, operates as a dedicated hardware component for industrial Ethernet communication within FA-M3 PLC networks. It handles data transfer between PLC units and upper-level control or monitoring systems over twisted-pair copper cabling.

Channel-to-Channel Isolation

The F3LE01-5T implements electrical separation between the communication channel and the internal module circuitry. This isolation prevents cross-interference and ensures signal integrity in dense industrial networks. Standard compliance maintains consistent voltage reference levels and mitigates common-mode noise propagation across connected devices.

Frequently Asked Questions

Q: Can the F3LE01-5T module support hot-swapping?
A: The module is not designed for hot-swap operations; power should be removed from the FA-M3 CPU before insertion or removal.

Q: What is the typical latency when multiple TCP/IP connections are active?
A: Latency depends on the total number of simultaneous connections and network load. The module supports up to 16 active TCP/IP or UDP/IP connections without internal data loss.

Q: Is firmware upgrade required for compatibility with newer CPU modules?
A: Firmware of the FA-M3 CPU must support the F3LE01-5T. Compatibility should be verified using Yokogawa WideField3 configuration software.

Field Installation Guidelines

• Mount the module in the FA-M3 slot with the latch fully engaged.
• Ensure RJ-45 connectors are firmly seated; use shielded twisted-pair cables to minimize EMI.
• Ground the cable shield at one end only to prevent ground loops.
• Maintain at least 10 cm spacing from high-current devices to reduce cross-talk.
• Observe the maximum 100 m segment length between the module and the network switch or hub.
