ControlLogix ControlNet communication modules bridge ControlNet links to
route messages to devices on other networks. The modules also monitor and
control I/O modules located remotely from the ControlLogix controller.
This module provides:
• adapter functionality for remote ControlLogix I/O modules.
• messaging data for configuration and programming information,
operator interfaces, upload/download.
This module supports:
• I/O bridge functionality for applications requiring less performance
than those applications that require the high-speed 1756-CN2(R).
• transfer of scheduled data via produced/consumed tags.

• unscheduled MSG instruction communication with other
ControlNet nodes.
• local communication network access through the network access port
(NAP).
• redundant media (1756-CNBR only).
