ControlLogix EtherNet/IP Communication Modules
For EtherNet/IP network communication in a ControlLogix system, you have
several modules to choose from.
Table 13 lists modules and their primary
features.
Table 13 - EtherNet/IP Communication Modules and Capabilities
Module Is used to
1756-ENBT • Connect controllers to I/O modules (requires an adapter for distributed I/O).
• Communicate with other EtherNet/IP devices (messages).
• Serve as a pathway to share data between Logix5000 controllers (produce/consume).
• Bridge EtherNet/IP nodes to route messages to devices on other networks.
1756-EN2T • Perform the same functions as a 1756-ENBT module, with twice the capacity for more
demanding applications.
• Provide a temporary configuration connection via the USB port.
• Configure IP addresses quickly by using rotary switches.
1756-EN2F • Perform the same functions as a 1756-EN2T module.
• Connect fiber media by an LC fiber connector on the module.
1756-EN2TR • Perform the same functions as a 1756-EN2T module.
• Support communication on a ring topology for a Device Level Ring (DLR) single-fault
tolerant ring network.
1756-EN2TRXT • Perform the same functions as a 1756-EN2T module.
• Support communication on a ring topology for a Device Level Ring (DLR) single-fault
tolerant ring network.
• Operate in extreme environments with -25…70 °C (-13…158 °F) temperatures.
1756-EN3TR • Perform the same functions as the 1756-EN2TR module.
• Extended Integrated Motion on EtherNet/IP network.
• Support of up to 128 motion axes.
1756-EN2TSC • Perform the same functions as a 1756-ENBT module, with twice the capacity for more
demanding applications.
• Provide a temporary configuration connection via the USB port.
• Configure IP addresses quickly by using rotary switches.
1756-EN2TXT • Perform the same functions as a 1756-EN2T module.
• Operate in extreme environments with -25…70 °C (-13…158 °F) temperatures.
1756-EWEB • Provide customizable web pages for external access to controller information.
• Provide remote access via an internet browser to tags in a local ControlLogix controller.
• Communicate with other EtherNet/IP devices (messages).
• Bridge EtherNet/IP nodes to route messages to devices on other networks.
• Support Ethernet devices that are not EtherNet/IP-based with a socket interface.
This module does not provide support for I/O or produced/consumed tags.
