Product Introduction
The Allen Bradley 1761-NET-DNI DeviceNet Interface Module is a compact communication interface designed to connect MicroLogix controllers to a DeviceNet network. Manufactured by Allen-Bradley, this module enables legacy MicroLogix systems to integrate seamlessly into distributed control architectures without requiring major hardware upgrades.
The 1761-NET-DNI functions as a communication bridge between DF1 serial protocol and DeviceNet. It allows MicroLogix 1000, 1200, and 1500 controllers to operate as DeviceNet nodes, exchanging cyclic and explicit messages with scanners, remote I/O, drives, and other intelligent field devices.
Designed for industrial environments, the module provides stable and deterministic communication performance. Its compact housing makes it suitable for installation in control panels where space is limited, while maintaining reliable operation under demanding temperature conditions.

FAQ
-
How does the module translate DF1 serial data into DeviceNet messages?
The module maps controller data files into DeviceNet I/O assemblies or explicit messaging structures, enabling structured and configurable communication between the PLC and network scanner. -
Can the module be used in multi-drop serial configurations?
Yes, it supports DF1 full duplex communication, allowing flexible serial integration depending on controller configuration. -
What baud rates are available and how are they configured?
The module supports 125, 250, and 500 kbps. Configuration is typically performed through network parameter settings to match the DeviceNet segment. -
Does the module provide electrical isolation?
Yes, electrical isolation protects both the serial interface and DeviceNet network from voltage fluctuations and ground potential differences. -
What types of DeviceNet messaging are supported?
Both cyclic I/O messaging and explicit messaging are supported for process data exchange and diagnostics. -
How is node addressing handled?
Node addresses are configured according to DeviceNet standards, typically via hardware switches or software configuration tools. -
Is the module compatible with third-party DeviceNet devices?
Yes, as long as the devices conform to DeviceNet specifications and proper EDS files are installed. -
What diagnostic information is available?
Status LEDs indicate module power, network status, and communication activity to assist in troubleshooting. -
Can firmware updates be applied in the field?
Firmware updates may be performed depending on hardware revision and supported tools. -
How does the module manage communication errors?
It continuously monitors network traffic and serial communication, detecting faults and reporting error conditions to assist system diagnostics.
