It includes two separate EtherNet/IP and DLR (Device-level Ring Network) network channels to quickly recover from network connection loss if one connection fails. It provides easy access to controller mode switches, USB ports, secure digital (SD) card slots, and power switches.

It weighs 15.50 pounds. It has a nominal input voltage of 24V DC and can be used to power other On-Machine products through. It has four M12 Class 5E Ethernet ports and a USB 1.1 full speed (12Mbps) USB port. It can be installed in any slot in the ControlLogix 1756 case, or multiple controllers can be installed in the same case. For standard communication, it uses an EtherNet/IP network with 256 EtherNet/IP and 128 TCP connections.

The 1756-L73EROM controller simplifies cabling and reduces cabinet hardware, so no special tools or personnel are required to replace components.

It also features new lenses that provide better status indication, display readability, and simplified troubleshooting.
