Frequently Asked Questions about 1756-EN2TR
Question: What is the 1756-EN2TR module?
Date Update:29/05/2025
Answer:

The 1756-EN2TR is an Ethernet/IP communication module for the ControlLogix system by Rockwell Automation. It is used to connect a ControlLogix PLC to an Ethernet network, allowing for high-speed, real-time communication between the PLC and other devices such as HMIs, remote I/O, and other networked devices.

Question: What is the weight of the 1756-EN2TR?
Date Update:29/05/2025
Answer:

The 1756-EN2TR module weighs approximately 0.5 kg (1.1 lbs). This makes it relatively lightweight and easy to install in a ControlLogix rack.

Question: What is the purpose of the dual Ethernet ports on the 1756-EN2TR?
Date Update:29/05/2025
Answer:

The dual Ethernet ports on the 1756-EN2TR module support network redundancy and cable fault tolerance. Using a feature known as Device-Level Ring (DLR), these ports can form a redundant ring network, ensuring that communication can still take place if one network path fails. This is crucial for applications where uptime and reliability are critical.

Question: What is the maximum number of devices that can be connected to the 1756-EN2TR module?
Date Update:29/05/2025
Answer:

The 1756-EN2TR module itself does not have a strict limit on the number of devices that can be connected to it, as this is primarily determined by the Ethernet network infrastructure and the network load. However, when used in Ethernet/IP networks, it can handle multiple devices depending on the available bandwidth, network configuration, and communication load. The network should be designed to handle the traffic of all connected devices.

Question: Where can I find the user manual for the 1756-EN2TR?
Date Update:29/05/2025
Answer:

The user manual and product documentation for the 1756-EN2TR module can be found on the Rockwell Automation website under the product support section. You can also access the manual from within the software environment, such as Studio 5000 or RSLogix 5000, by navigating to the help section. The manual includes detailed information on installation, configuration, and troubleshooting.
