FAQ

Q: What programming software is required to configure the 2MLL-EFMTB?
A: The module is configured using Honeywell SoftMaster-NM software. IP address, subnet mask, gateway, DNS server, and firewall settings are all managed through this interface.

Q: Is this module compatible with redundant Ethernet topologies?
A: The 2MLL-EFMTB supports standard Ethernet networking. For redundant architectures, pair with appropriate network switches and cable the module into a ring or star topology as required by your plant design.

Q: Can the module obtain an IP address automatically?
A: Yes, the module supports DHCP protocol for dynamic IP assignment, making it suitable for ADSL and dynamic IP environments.

Installation Guide

• Install the module into an available slot of a MasterLogic-200 chassis.
• Connect a shielded Category 5e or higher twisted-pair cable to the RJ-45 port.
• Configure the IP address, subnet mask, and gateway using SoftMaster-NM software before commissioning.
• For public network access, set the DNS server and gateway IP addresses as required by your network administrator.
• Enable DHCP only if your network supports dynamic IP assignment.
• Verify link status via the module's LED indicators before bringing the system online.

Selection Tips

• Network Speed: Confirm your plant network infrastructure supports 10/100 Mbps Ethernet and 100Base-TX cabling before selecting this module.
• Protocol Requirements: Choose the 2MLL-EFMTB if your application requires TCP/IP or UDP/IP communication. For fiber optic applications, consider the 2MLL-EFMF (SC type fiber optic variant).
• Configuration Access: Ensure SoftMaster-NM software is installed and licensed on your engineering workstation prior to module deployment.
• Chassis Compatibility: The module is designed for MasterLogic-200 series racks. Verify available slot capacity in your existing or planned chassis configuration.
