The Allen-Bradley 1756-EN2TR is a dual EtherNet/IP interface module for the ControlLogix family of programmable logic controllers (PLCs). It provides two independent 100BASE-TX Ethernet ports that can be used to connect to a variety of devices, including other PLCs, HMIs, databases, and sensors. The module supports both TCP/IP and CIP (ControlNet Industrial Protocol) protocols.

Features

• Two independent EtherNet/IP ports
• Supports up to 128 TCP connections and 256 CIP connections
• 10/100 Mbps Ethernet speed
• Supports both standard and secure (SSL/TLS) communication
• DIN rail mounting
