It is an interface converter module that allows the MicroLogix or SLC controller to communicate with devices using various protocols such as DF1, DH-485, and ASCII.

The 1761-NET-AIC module provides serial communication capabilities and supports both RS-232 and RS-485 communication interfaces. It can be used to connect the PLC to other devices such as human-machine interfaces (HMIs), panelView displays, and other controllers in a networked environment.

The module is typically installed in the communication port of the MicroLogix or SLC controller and facilitates data exchange between the controller and other devices. It supports a range of communication modes such as point-to-point, multi-point, and multi-drop configurations, allowing for flexible network topologies.
