With our extensive experience serving global markets from North America to Europe and Asia, we understand the critical need for reliable communication hardware, and the 1756-EN2TP stands as a cornerstone solution for scalable and efficient plant-wide control.

Product Overview & Core Advantages
The Allen-Bradley 1756-EN2TP is a dual-port EtherNet/IP network interface module designed for the ControlLogix platform. It serves as the communication bridge between the controller's backplane and an EtherNet/IP network, enabling real-time control, data collection, and device interoperability. Its primary value lies in enhancing system flexibility and simplifying network architecture.

Enhanced Network Reliability & Speed: Featuring two auto-sensing 10/100 Mbps RJ45 ports, the module supports both linear and device-level ring (DLR) topologies. This dual-port design allows for redundant network connections, significantly improving network availability and fault tolerance—a critical feature for mission-critical automation applications.
Seamless Integration with ControlLogix: The module plugs directly into any 1756 ControlLogix chassis slot, instantly providing EtherNet/IP network access to all controllers and I/O modules within the same chassis. It simplifies programming and configuration through Rockwell Automation's Studio 5000 Logix Designer software.
Comprehensive Protocol Support: Beyond core EtherNet/IP implicit and explicit messaging for control and information, it supports CIP Sync, CIP Motion, and CIP Safety services over standard Ethernet, enabling synchronized motion control and safety system integration on a single network cable.
Superior Diagnostics and Management: The module offers advanced diagnostic capabilities through web-based interfaces and LED status indicators, allowing for quick troubleshooting of network health, connection status, and data transmission issues, thereby reducing downtime.
Scalable and Future-Proof Solution: As part of the integrated architecture from Rockwell Automation, the 1756-EN2TP facilitates easy system expansion. It connects not only to controllers and I/O but also to a vast ecosystem of drives, HMIs, and other smart devices, protecting your investment as your automation needs grow.

Frequently Asked Questions (FAQ)

Q: What is the main difference between the 1756-EN2T and the 1756-EN2TP?
A: The primary difference is that the 1756-EN2TP model features two physical RJ45 network ports, while the EN2T typically has one. The dual ports on the EN2TP enable device-level ring (DLR) topology support and network redundancy, offering higher availability.
Q: Can this module be used in an existing ControlLogix system with older communication modules?
A: Yes, it is designed to be backward compatible within the 1756 platform. You can replace an older Ethernet module with the 1756-EN2TP, but a firmware update and reconfiguration of the project in Logix Designer may be required for optimal performance.
Q: Does it support connecting to third-party devices over EtherNet/IP?
A: Yes, the EtherNet/IP protocol is an open standard. The 1756-EN2TP can communicate with any device that supports the CIP protocol suite, including drives, I/O blocks, and sensors from various manufacturers, provided they are properly configured.
Q: What is required for the initial setup and configuration?
A: You will need Rockwell Automation's Studio 5000 Logix Designer software (appropriate version for your controller). The module is configured through the software by setting its IP address, network parameters, and defining the produced/consumed tags for data exchange.
Q: Is it possible to achieve redundant communication paths with this module?
A: Absolutely. The dual ports allow you to connect the module into a Device-Level Ring (DLR) topology. If one network path fails, communication automatically continues through the alternative path, providing a robust level of network redundancy.
Q: What kind of Ethernet cable should be used for installation?
A: Standard Category 5e (Cat 5e) or higher (Cat 6, Cat 6a) shielded or unshielded twisted-pair (UTP/STP) cables with RJ45 connectors are suitable for the 10/100 Mbps connections. For industrial environments with high EMI, shielded cables are often recommended.
Q: Can this module handle safety and motion control data on the same network?
A: Yes, it supports CIP Safety and CIP Motion services over EtherNet/IP. This allows safety devices and coordinated motion axes to share the same network infrastructure as standard I/O control, simplifying cabling and system architecture.
Q: How does Rossonix ensure the authenticity and quality of the Allen-Bradley modules supplied?
A: As an established trading company operating since 2011 with ISO9001/9000 referenced quality standards in our supply chain, we source components directly from authorized distributors or reputable channels. We provide all necessary documentation to verify authenticity and offer reliable after-sales support.
