Product Details

F3LE01-5T Product Description

The Yokogawa F3LE01-5T is a high-performance Ethernet Interface Module engineered for seamless integration within the FA-M3 modular PLC platform. Designed to serve as the primary communication backbone between the FA-M3 control layer and upper-level supervisory systems, the F3LE01-5T delivers deterministic, high-speed Ethernet connectivity that supports SCADA, DCS, MES, and historian platforms across demanding industrial environments. Its architecture-first design ensures that every deployment maintains signal integrity, communication stability, and long-term maintainability — from initial commissioning through decades of continuous operation.

As industrial automation systems evolve toward integrated, multi-layer architectures, the role of the Ethernet interface module becomes increasingly critical. The F3LE01-5T addresses this need by providing a robust, standards-compliant 100BASE-TX Ethernet port that bridges the FA-M3 CPU layer with plant-wide communication networks. Whether deployed in a standalone FA-M3 rack or as part of a distributed control architecture spanning multiple cabinets and remote I/O stations, the F3LE01-5T ensures that real-time process data flows reliably from field devices to control rooms and enterprise systems.

The F3LE01-5T is not a standalone component — it is a system-level enabler that unlocks the full communication potential of the FA-M3 platform. In a typical FA-M3 control architecture, the F3LE01-5T occupies a dedicated slot in the F3SP-series base unit alongside the FA-M3 CPU module (such as the F3SP71-4N or F3SP76-7N), which handles ladder logic execution, sequence control, and real-time process management. The Ethernet interface module extends the CPU's reach beyond the local rack, enabling high-speed data exchange with remote systems without burdening the CPU's internal communication resources.

On the I/O layer, the F3LE01-5T works in concert with FA-M3 analog input modules (F3AD08-6R, F3AD04-6H), digital I/O modules (F3XD32-3N, F3YD32-3T), and temperature input modules (F3CT04-1N) to aggregate field-level process data and transmit it upstream via Ethernet. This layered approach ensures that signal acquisition, processing, and communication remain modular and independently scalable — a critical advantage in large-scale process plants where I/O counts can reach into the thousands.

For distributed architectures, the F3LE01-5T enables peer-to-peer communication between multiple FA-M3 racks deployed across a facility, supporting coordinated control strategies without requiring a centralized communication master. When paired with the F3LR01-1N remote I/O master module, the architecture can extend to remote I/O stations located hundreds of meters from the main control cabinet, maintaining deterministic scan times and reliable data integrity across the entire system.

At the power layer, the FA-M3 system relies on dedicated power supply modules such as the F3PU20-0S or F3PU10-0S to deliver stable, regulated DC power to all modules within the base unit. The F3LE01-5T draws its operating power directly from the backplane bus, eliminating the need for external power wiring and simplifying cabinet layout. Proper power budget planning — accounting for the combined current draw of CPU, I/O, and communication modules — is essential for reliable long-term operation.

For HMI integration, the F3LE01-5T provides the Ethernet backbone that connects FA-M3 controllers to Yokogawa's ProSafe-RS safety system HMI, third-party SCADA platforms (such as Wonderware InTouch or Ignition), and web-based monitoring dashboards. The module supports simultaneous connections from multiple HMI clients, enabling operators at different workstations to access real-time process data without communication conflicts. This multi-client capability is particularly valuable in large control rooms where multiple operators monitor different sections of the same process.

In redundant architecture designs, the F3LE01-5T can be deployed in dual-module configurations within FA-M3 systems that support communication redundancy, ensuring that a single Ethernet module failure does not interrupt supervisory communication. When combined with redundant CPU modules and redundant power supplies, this approach delivers the high-availability architecture required in critical process industries such as oil and gas, power generation, and chemical manufacturing.

Manufacturing & Discrete Automation: In automotive assembly lines and electronics manufacturing facilities, the F3LE01-5T enables real-time production data collection from FA-M3 controllers managing conveyor systems, robotic welding stations, and quality inspection equipment. The Ethernet interface allows MES platforms to retrieve cycle time data, reject counts, and equipment status in real time, supporting OEE analysis and continuous improvement programs.

Power Generation & Utilities: In thermal power plants and hydroelectric facilities, the F3LE01-5T connects FA-M3 controllers managing turbine auxiliary systems, cooling water circuits, and fuel handling equipment to plant-wide DCS and SCADA platforms. The module's robust EMC compliance ensures reliable communication in environments with high electromagnetic interference from large motors, transformers, and switchgear.

Petrochemical & Refining: In refinery process units and petrochemical plants, the F3LE01-5T supports integration between FA-M3 controllers managing utility systems (compressed air, cooling water, steam distribution) and the plant's primary DCS. This integration enables centralized alarm management, historian data collection, and remote diagnostics — reducing the need for on-site maintenance visits and improving overall plant availability.

Water & Wastewater Treatment: In municipal water treatment plants and industrial wastewater systems, the F3LE01-5T enables FA-M3 controllers to communicate with SCADA systems monitoring pump stations, chemical dosing systems, and filtration processes across geographically distributed sites. The module's support for Modbus TCP ensures compatibility with a wide range of third-party SCADA platforms commonly used in the water industry.

Mining & Metallurgy: In mineral processing plants and smelting facilities, the F3LE01-5T provides the communication link between FA-M3 controllers managing crushing, grinding, flotation, and smelting processes and the plant's supervisory control system. The module's industrial-grade construction ensures reliable operation in environments with high dust levels, vibration, and temperature extremes.

Q1: How many simultaneous Ethernet connections does the F3LE01-5T support, and is it compatible with third-party SCADA systems? The F3LE01-5T supports multiple simultaneous TCP/IP connections, enabling concurrent communication with SCADA servers, HMI clients, historian platforms, and peer FA-M3 controllers. The module's support for Modbus TCP and standard TCP/IP protocols ensures broad compatibility with third-party SCADA platforms including Wonderware, Ignition, iFIX, and Citect. For Yokogawa-native integration, the module supports the FA-M3 Ethernet communication protocol for optimized data exchange with Yokogawa SCADA and DCS systems.

Q2: Can the F3LE01-5T be used in a redundant communication architecture, and what are the installation requirements? The F3LE01-5T is designed for slot installation in FA-M3 base units (F3BU-series). For applications requiring communication redundancy, two F3LE01-5T modules can be installed in separate slots and configured for active/standby operation, depending on the FA-M3 CPU model and firmware version. Each module requires a dedicated slot and draws power from the backplane bus — no external power wiring is needed. Proper grounding of the control cabinet and use of shielded Ethernet cables are recommended to ensure EMC compliance and signal integrity in industrial environments.

Q3: What is the warranty coverage for the F3LE01-5T, and what inventory and lead time should be expected? All F3LE01-5T units supplied by NANKMOS are covered by a 12-Month Warranty against manufacturing defects and functional failures under normal operating conditions. Units are sourced from verified supply channels and undergo pre-shipment functional testing to confirm Ethernet communication, backplane interface integrity, and LED status indicator operation. Stock availability is maintained for rapid dispatch, with standard lead times of 3–7 business days for in-stock units.
