Honeywell 2MLL-EFMTB Fast Ethernet Module

Honeywell 2MLL-EFMTB Fast Ethernet Copper Module

Product Introduction

The 2MLL-EFMTB is a Fast Ethernet communication module for the Honeywell MasterLogic-200 programmable logic controller series. This module connects the PLC to plant networks over standard twisted-pair copper cable. Specifically, it brings Ethernet connectivity to controllers, engineering stations, and supervisory systems without fiber infrastructure.

Automation teams pick this module for general-purpose network integration on the factory floor. Furthermore, the 10/100 Mbps auto-negotiation matches both legacy and modern switch ports. Meanwhile, the copper physical layer keeps cabling costs low in short-distance installations. Consequently, the 2MLL-EFMTB handles the majority of standard PLC networking duties in a typical plant.

Technical Specifications

The module conforms to the IEEE 802.3U Ethernet standard and supports both TCP-IP and UDP-IP protocols. Network access uses the CSMA/CD method for collision detection and management. Meanwhile, transmission speed reaches 10/100 Mbps over a 100BaseTx twisted-pair physical layer.

Core network parameters include:

• Ethernet Standard: IEEE 802.3U

• Protocols: TCP-IP, UDP-IP

• Physical Layer: 100BaseTx (Twisted Pair)

• Transmission Speed: 10/100 Mbps

• Configuration Software: SoftMaster-NM

• Weight: 0.105 kg

The module supports a software firewall configurable through SoftMaster-NM. Specifically, engineers set IP addresses and access rules within this software environment. Therefore, basic network segmentation and access control come built into the platform.

Public Network and DHCP Features

Public network access relies on DNS server and gateway IP address settings. Besides, the module supports dynamic IP address assignment for ADSL links through the DHCP protocol. This flexibility suits plants that connect PLCs to corporate networks or remote monitoring services.

Dynamic addressing simplifies deployment in networks where the IT department manages IP ranges. Moreover, the gateway and DNS settings enable the controller to reach external services when required. In addition, the software firewall adds a layer of protection at the module level.

Mechanical and Environmental Parameters

The 2MLL-EFMTB weighs only 0.105 kg, making it one of the lightest modules in the MasterLogic-200 range. It mounts as a plug-in card inside the PLC rack and draws power from the backplane. Meanwhile, the compact front panel keeps cabinet space efficient.

The module operates within the ambient conditions of the MasterLogic-200 platform. Additionally, the twisted-pair interface includes standard noise immunity for industrial cable runs. For instance, shielded cable further improves performance in high-EMI areas near drives and welders.

Installation Guide

First, shut down the rack power and confirm the backplane is safe to touch. Next, insert the 2MLL-EFMTB into an available communication slot and press until it clicks into place. Then, fasten the retaining screws to hold the card firmly.

After mounting, connect a shielded twisted-pair cable to the RJ45 port and route it away from power cables. Subsequently, open SoftMaster-NM and set the IP address, subnet mask, and gateway. Finally, enable DHCP only if the network requires dynamic addressing, then run a Ping test to verify connectivity.

FAQ

Q1: What transmission speed does the 2MLL-EFMTB support?
A1: The module supports 10/100 Mbps over a 100BaseTx twisted-pair physical layer, conforming to the IEEE 802.3U standard.

Q2: Does this module work with fiber optic cable?
A2: No, the 2MLL-EFMTB uses copper twisted-pair cable only. For fiber connections, choose the separate FEnet fiber module variant.

Q3: Can the module obtain an IP address automatically?
A3: Yes, it supports the DHCP protocol for dynamic IP assignment, which suits ADSL links and IT-managed networks.

Q4: How is the software firewall configured?
A4: IP address settings and firewall rules are configured through the SoftMaster-NM software, the same tool used for general module setup.

Q5: How do you ship this product?
A5: We ship via Fedex, UPS, and DHL. Each unit travels in anti-static packaging inside a shock-absorbing box for safe delivery.
