Allen-Bradley 1756-ENBTA EtherNet/IP Communication Module

A reliable workhorse for industrial network integration. This module bridges ControlLogix controllers with EtherNet/IP networks, enabling seamless data flow in manufacturing and process control environments. We’ve deployed these in everything from automotive assembly lines to food processing plants where consistent network performance matters.

Real-World Applications

We’ve installed these modules in diverse settings – from steel mills where vibration resistance matters, to cleanroom pharmaceutical facilities needing strict network segmentation. They’re particularly effective in systems requiring Device Level Ring (DLR) redundancy, where network uptime directly impacts production output.

For example, a recent textile manufacturing client used these to connect 1756-L71 controllers with their plant-wide EtherNet/IP network, achieving 0.5ms latency between HMIs and field devices. Common companion models in our inventory include the 1756-L7 controllers and 1794-IB16 input modules.

While some newer modules offer gigabit speeds, this model remains popular for retrofitting legacy systems where proven reliability outweighs theoretical performance gains. In fact, about 60% of our repeat customers specifically request this module for brownfield projects.
