1756-EN4TR is applied in ControlLogix systems that require high-capacity EtherNet/IP communication, resilient network paths and integrated motion connectivity. Application engineering must confirm the chassis series, firmware, connection loading, topology, security policy and controller-project configuration.
1756-EN4TR is compatible with documented Allen-Bradley ControlLogix chassis, controllers and EtherNet/IP network configurations that support the module revision and firmware. Confirm chassis series, backplane capacity, Studio 5000 profile, electronic keying, connection loading, network topology and CIP Security policy before installation or replacement.
Rockwell Automation continues to document 1756-EN4TR within the ControlLogix EtherNet/IP communication-module family. Before replacement, record the complete catalog number, module revision, firmware, chassis series, IP addressing, topology, redundancy settings, CIP Security policy and controller-project configuration. Use the current manufacturer documentation and approved migration procedure for the installed system.
