About the Allen-Bradley 1756-EN2TPXT

The Allen-Bradley 1756-EN2TPXT is a ControlLogix EtherNet/IP communication module. Rockwell's own summary: EtherNet/IP communication module, PRP dual port, 10/100M twisted pair, 128 TCP connections, extreme environment. Rockwell's technical data gives 10/100 Mbps on two RJ45 Ethernet ports (Category 5), 128 TCP and 256 Logix communication connections, and a current draw of 1 A. Rockwell Automation lists it as Active.

What is the 1756-EN2TPXT used for?

The 1756-EN2TPXT connects a ControlLogix chassis to EtherNet/IP, for I/O, messaging, and links to other controllers and HMIs. PRP sends each message over two independent networks, so the link survives the loss of one.
