Description

Yokogawa F3LE11-1T Ethernet Interface Module

Configured for Ethernet communication and remote programming execution in FA-M3 controller network environments, the FA-M3 F3LE11-1T (F3LE11-1T Ethernet Interface Module) provides direct physical/electrical execution for IEEE 802.3 based industrial communication over 10BASE-T and 100BASE-TX infrastructures.

The module operates as an I/O slot-mounted communication interface for FA-M3 range-free multi-controller systems, enabling TCP/IP based data exchange, SMTP/POP3 messaging, and higher-level link services for sequence CPU device access and remote program management.

Industrial Control Network Backplane Communication Behavior

The FA-M3 F3LE11-1T integrates into PLC backplane architectures where deterministic scan exchange is synchronized with Ethernet frame handling. In mixed module configurations, backplane bus arbitration governs cyclic refresh of CPU device tables while Ethernet stack tasks operate asynchronously over TCP/IP sockets. Firmware flash compatibility is dependent on controller CPU generation and I/O slot mapping consistency during module initialization.

Frequently Asked Questions

Q: Does the module support simultaneous 10 Mbps and 100 Mbps operation?
A: No. The interface performs automatic negotiation but operates in a single active link state per port (either 10BASE-T or 100BASE-TX).

Q: Can SMTP/POP3 functions access internal CPU device registers directly?
A: Yes. Device values can be mapped into email payloads through supported higher-level link service functions.

Q: What is the impact of installing multiple communication modules in the same FA-M3 base?
A: The total number of similar communication modules is limited by CPU type, and backplane resource allocation may restrict concurrent link sessions and sampling trace operations.

Field Installation Guidelines

Install the module only in designated FA-M3 I/O slots with controller power removed. Ensure correct seating into backplane connectors to maintain signal integrity across the Ethernet PHY interface. Use shielded twisted-pair cable compliant with 10/100BASE-TX standards, with shield termination grounded at a single-point earth reference to minimize noise coupling.

Avoid routing Ethernet cables parallel to high-voltage or inverter output lines. Maintain minimum separation consistent with industrial EMC wiring practices. Verify link status LEDs after power-up and confirm IP stack initialization via FA-M3 programming tool before enabling remote access functions.
