System Configuration and Networking

Because the 1756-L62 does not include an integrated Ethernet interface, network communication with distributed I/O, supervisory networks, or operator interfaces requires one or more compatible 1756 communication modules installed in the local chassis, selected according to the target network architecture. Confirm slot availability, power supply capacity, battery status, and firmware revision before installation.
