Allen-Bradley 1761-NET-DNI DeviceNet Interface

Allen-Bradley 1761-NET-DNI DeviceNet Interface is a gateway module that bridges a DeviceNet fieldbus with a DF1 serial device, allowing legacy DF1-equipped controllers to communicate with DeviceNet devices on a single network. As part of the 1761 family, the DNI (DeviceNet Interface) provides a dedicated DF1-to-DeviceNet bridge that lets you connect a MicroLogix or SLC 500 controller to DeviceNet field devices such as sensors and actuators without replacing existing serial equipment. This unit, firmware FRN 2.01 CC2, is cataloged as 1761-NET-DNI and functions as a DeviceNet interface that enables data exchange between a DF1 link and a DeviceNet network. In typical installations, the DNI sits between the controller's DF1 port and the DeviceNet bus, presenting a DeviceNet node to the network while handling serial communications with the DF1 device. Engineers use the 1761-NET-DNI to extend DeviceNet connectivity to older equipment, enabling centralized monitoring and control of DeviceNet devices alongside DF1-based devices. By bridging these two protocols, the module supports mixed environments where legacy serial devices must share data with modern DeviceNet I/O, reducing the need for complete equipment replacement while preserving existing control architectures.
