EtherNet/IP Deterministic Network Characteristics
The 1757-EN2TR provides dual Ethernet interfaces with embedded switch functionality for ControlLogix communication architectures. The module supports EtherNet/IP deterministic networks using linear and Device Level Ring (DLR) topologies for controller, I/O, and supervisory communication paths.
The embedded switch enables network configuration flexibility by allowing ring and line arrangements without requiring an external Ethernet switch for these topologies. The module supports I/O density scaling through high-volume packet processing capability and multiple simultaneous communication connections.
Firmware flash compatibility between the communication module and ControlLogix controller platform must be verified to maintain correct EtherNet/IP operation and network integration.

A: The module supports up to 128 TCP connections and 260 CIP connections.
Q: Does the 1757-EN2TR include a programming interface?
A: Yes. The module includes one USB port intended for local programming access.
Field Installation Guidelines
Install the 1757-EN2TR in a compatible ControlLogix chassis slot according to the system hardware configuration requirements. Verify proper module seating and backplane connection before applying power.
Connect Ethernet cables to the RJ45 ports using industrial Ethernet installation practices. Maintain separation between communication cables and high-current power conductors to reduce electromagnetic interference.
For DLR installations, verify ring topology wiring, device addressing, and network configuration before system operation. Apply proper cable shielding and grounding methods according to the control cabinet design.
Before commissioning, verify EtherNet/IP network parameters, controller communication settings, firmware compatibility, and module diagnostic status through the ControlLogix engineering environment.
