Honeywell 2MLL-EFMT-CC Fast Ethernet Module Overview

The Honeywell 2MLL-EFMT-CC is a high-performance Fast Ethernet module. It belongs to the MasterLogic-200 Series from Honeywell. This module provides reliable network connectivity for industrial PLC systems. You can use it for high-speed data exchange and remote monitoring. The 2MLL-EFMT-CC supports multiple industrial protocols for flexible integration.

Technical Specifications

The 2MLL-EFMT-CC follows the IEEE802.3u Ethernet standard. It operates at 10/100 Mbps transmission speeds. The physical layer uses 100baseTx (T.P) technology. This module connects via an RJ-45 electric interface. It requires UTP/STP CAT5 cables for proper operation. The maximum transmission distance reaches 100 meters per node.

This module supports a CSMA/CD access method. It uses baseband transmission for reliable signal integrity. You can connect up to 64 nodes in a single network. The supply voltage is 24 VDC with a rating of 24V. Typical current consumption stays at 410 mA. The unit weighs only 105 grams for easy mounting.

Protocol and Software Support

The 2MLL-EFMT-CC supports TCP-IP and UDP-IP protocols. It includes HSL (Peer-to-Peer High Speed Link) for fast PLC communication. Each HSL block holds 200 words with up to 128 blocks. The module also supports MLDP (MasterLogic Dedicated Protocol) for Experion integration. You can use Modbus TCP slave mode for third-party device connections.

The P2P function works as a Modbus TCP master. It also supports user-defined master protocols. Use SoftMaster-NM software for full configuration and diagnostics. The module includes a software firewall via IP address settings. You can set DNS server and Gateway IP addresses for public network access. The DHCP protocol allows dynamic IP address assignment for ADSL networks.

LED Indicators and Network Diagnostics

The 2MLL-EFMT-CC features multiple status LEDs for easy troubleshooting. These LEDs include RUN, I/F, HS, P2P, PADT, PC, ERR, TX, RX, and 10/100. Each LED provides real-time operational feedback. The module also supports powerful network diagnostic tools. You can perform auto-scan, ping test, frame monitor, and link monitor. These tools help maintain network stability and performance.

Installation Guidelines

Always power off the PLC before installing the 2MLL-EFMT-CC module. Insert the module firmly into an available slot in the MasterLogic-200 rack. Secure the module using the built-in locking mechanism. Connect a CAT5 UTP/STP cable to the RJ-45 port. Ensure the cable length does not exceed 100 meters. Use SoftMaster-NM to assign a unique IP address to the module. Configure the gateway and DNS settings for your network. After configuration, cycle power to activate the new settings.
