Description
The Allen-Bradley 1756-EN2T is a ControlLogix EtherNet/IP communication module manufactured by Rockwell Automation for high-speed industrial Ethernet communication within ControlLogix automation systems. The module provides 10/100 Mbps EtherNet/IP connectivity for controller communication, distributed I/O control, HMI integration, programming access, and industrial data exchange across plant-wide automation networks.
The module supports CIP messaging, distributed I/O communication, produced/consumed tags, and bridging between industrial networks within ControlLogix architectures. It is designed for high-performance applications requiring reliable industrial Ethernet connectivity and supports integration with CompactLogix, POINT I/O, PanelView, SCADA, and other EtherNet/IP-enabled automation devices. The 1756-EN2T installs directly into a 1756 ControlLogix chassis and operates through Studio 5000 Logix Designer environments.
