F3LE12-0T Yokogawa Ethernet Interface Module

Hardware Specifications

Ethernet Communication and FA-M3 Interface

The F3LE12-0T transfers controller data through an Ethernet physical interface. The module supports both 10BASE-T and 100BASE-TX transmission and uses auto-negotiation to establish the supported link parameters.

The RJ-45 interface provides the external network connection. TCP/IP and UDP/IP support enables application-level data exchange, while ICMP and ARP provide standard IP network functions.

In addition, the module supports communication between FA-M3 controllers and higher-level devices. The supplied specifications identify remote programming, monitoring, debugging, and CPU device data access as supported functions. Therefore, the Ethernet connection can carry both controller maintenance traffic and higher-level data communication.

The module receives its operating power from the FA-M3 backplane and occupies one I/O slot. Its maximum stated current consumption is 330 mA at 5 VDC.

Frequently Asked Questions

Q: What Ethernet speeds does the F3LE12-0T support?
A: The module supports 10BASE-T and 100BASE-TX. It provides full-duplex and half-duplex auto-negotiation.

Q: Does the F3LE12-0T require an external power supply?
A: No separate external power input is specified. The module receives 5 VDC through the FA-M3 backplane and consumes up to 330 mA.

Q: Does the supplied data confirm hot-swap operation?
A: No hot-swap capability is stated in the supplied specifications. Installation and removal should therefore follow the applicable FA-M3 hardware installation procedure.

Field Installation Guidelines

Install the F3LE12-0T in the designated FA-M3 base-unit slot and secure the module according to the controller hardware installation procedure.

Connect the Ethernet cable to the RJ-45 port and use Category 5 or higher twisted-pair cable for the specified 10BASE-T or 100BASE-TX connection. Keep Ethernet wiring separated from high-voltage power conductors and high-current switching circuits to reduce electromagnetic interference.

Route communication cables with appropriate mechanical support and avoid excessive bending or tensile loading at the RJ-45 connector. Where shielded network cabling is used, apply the grounding arrangement specified by the FA-M3 installation documentation and the site electrical standard.

Before commissioning, verify the network connection, IP configuration, communication protocol settings, and controller-side communication parameters. Also confirm that the backplane power system can supply the module’s stated maximum current consumption.
