The 1756-EN2TR/C is an Ethernet/IP communication module manufactured by Allen-Bradley, which is part of the ControlLogix family of programmable logic controllers (PLCs). This module allows communication between ControlLogix PLCs and other devices on an Ethernet/IP network.
The 1756-EN2TR/C module provides two Ethernet ports for network connectivity. It supports both single and redundant network configurations, providing increased reliability and fault tolerance. The "EN2TR" in the module's name stands for "Ethernet/Network 2-port, Tap Interface," indicating its dual-port functionality.
With the 1756-EN2TR/C module, you can establish communication between the PLC and various devices such as HMI (Human Machine Interface) panels, distributed I/O systems, motion controllers, and other network-enabled devices. It uses the Common Industrial Protocol (CIP) over Ethernet/IP for device communication.
The module is typically configured using the Allen-Bradley RSLogix 5000 software, which allows you to program and configure the ControlLogix PLC system. Through the software, you can set up the network parameters, configure the module's communication settings, and establish connections with other devices on the network.
