Honeywell 2MLL-EFMT MasterLogic-200 Fast Ethernet Module
The Honeywell 2MLL-EFMT is a Fast Ethernet communication module engineered for the MasterLogic-200 PLC system. It provides high-speed Ethernet connectivity between MasterLogic controllers, supervisory SCADA networks, DCS platforms, and HMIs over standard CAT5 twisted-pair cabling.
Communication Protocols and Networking Capabilities
Operating under IEEE 802.3 and IEEE 802.3u standards, the module supports 10/100 Mbps auto-negotiating transmission speeds via standard RJ45 connectors. It implements TCP/IP and UDP/IP network stacks, enabling industrial protocol support for Modbus TCP, MasterLogic Dedicated Protocol (MLDP), and High-Speed Link (HSL). Up to 64 network nodes can be interconnected per segment across distances of up to 100 meters using baseband CSMA/CD access.
Modular Installation and Diagnostics
Designed for direct insertion into standard MasterLogic-200 PLC racks, the module features built-in LED indicators for real-time channel diagnostics and link monitoring. IP address assignment can be configured using static IP settings or DHCP, simplifying commissioning across industrial control cabinets.
