2MLL-EFMT | Honeywell Fast Ethernet Module for MasterLogic-200 - Petro Auto Tech

Product Overview

The 2MLL-EFMT is a Honeywell Fast Ethernet Module designed for the MasterLogic-200 Series PLCs. This module enables high-speed network communication, supporting 10/100 Mbps transmission over standard RJ-45 connectors. It is a critical component for industrial automation systems requiring reliable data exchange and remote monitoring.

Technical Specifications Analysis

The module operates on a 24 VDC supply and complies with IEEE 802.3u Ethernet standard. It uses TCP-IP and UDP-IP protocols with CSMA/CD access method. The physical layer is 100BaseTx over UTP/STP CAT5 cabling, supporting a transmission distance of up to 100 meters per segment. It can connect up to 64 nodes in a network. The module includes a software firewall for IP address management via SoftMaster-NM software. Additional features include HSL peer-to-peer high-speed link, MLDP for Experion interface, Modbus TCP slave, and P2P protocols. Current consumption is 410 mA, and weight is 105 grams.

Application Scenarios & Usage Methods

This module is ideal for manufacturing plants using Honeywell MasterLogic-200 PLCs to control assembly lines or process equipment. For example, in a packaging facility, the 2MLL-EFMT can connect multiple PLCs via HSL protocol for synchronized high-speed data exchange. Use the SoftMaster-NM software to configure IP addresses and enable DHCP for dynamic addressing in large networks. Another scenario is in water treatment systems, where the module links remote I/O stations to a central controller using Modbus TCP slave protocol. Set up the firewall to restrict unauthorized access and ensure network security.

Installation Guide & Packing List

Install the module into an available slot on the MasterLogic-200 backplane. Connect the 24 VDC power supply to the designated terminals. Use a standard RJ-45 cable with CAT5 UTP/STP wiring to link the module to a network switch or directly to another node. Ensure the transmission distance does not exceed 100 meters. The packing list typically includes one 2MLL-EFMT Fast Ethernet Module and a quick start guide. No additional cables or software are included.

Purchasing Advice

When buying the 2MLL-EFMT, verify that your existing MasterLogic-200 system supports this module. Check the network topology requirements and ensure you have the SoftMaster-NM software for configuration. Petro Auto Tech offers genuine Honeywell modules with reliable sourcing and fast delivery. Consider purchasing a spare module to minimize downtime in critical applications.

Repair & Maintenance Tips

Regularly inspect the RJ-45 connectors for dust or corrosion. Clean the module with a dry, lint-free cloth. Store the module in a static-free environment when not in use. Monitor the LED indicators (RUN, ERR, TX, RX) for network faults. Avoid exposing the module to moisture or extreme temperatures. If the module fails, replace it immediately to restore network communication.
