Allen-Bradley 1771-ACN15 CNET I Adapter Module provides a ControlNet interface for 1771 I/O systems, enabling an I/O rack to communicate on a ControlNet network. It acts as the bridge between the local 1771 I/O backplane and the ControlNet network to support deterministic data exchange for industrial automation tasks. The 1771-ACN15 designation identifies this specific ControlNet adapter module in the 1771 I/O family.
