Product Overview

The Allen-Bradley 1769-SDN serves as the primary gateway for integrating DeviceNet networks into CompactLogix and MicroLogix 1500 control systems. This Series B module acts as a network master, orchestrating high-speed data exchange between the controller and up to 64 slave devices, including variable frequency drives (VFDs), discrete sensors, and HMI panels. We offer this unit in 100% Brand New original condition, providing a reliable communication backbone for legacy and modern DeviceNet architectures.

Engineering Advantages

The 1769-SDN addresses complex networking challenges by centralizing device management and optimizing bandwidth across the industrial floor.

Massive Node Scalability: A single 1769-SDN manages up to 64 nodes. This allows engineers to consolidate extensive sensor arrays and motor controls into one I/O bank, reducing the need for multiple communication modules.
Auto-Device Replacement (ADR): The scanner supports ADR functionality. When a slave device fails, the 1769-SDN automatically downloads configuration data to the replacement unit, drastically reducing Mean Time to Repair (MTTR) without requiring manual software intervention.
Selectable Baud Rates: The module supports 125k, 250k, and 500k baud rates. This flexibility allows you to balance network length (up to 500m) against high-speed data requirements for precise process control.
Compact Footprint for Retrofits: Designed for the 1769 Compact I/O platform, this module fits into narrow DIN-rail spaces. It provides an ideal solution for upgrading MicroLogix 1500 or CompactLogix systems to communicate with modern DeviceNet field instruments.
Advanced Network Diagnostics: Three distinct dual-color LEDs provide instantaneous feedback on module health and network traffic. This eliminates guesswork during commissioning by pinpointing bus errors or node conflicts immediately.

FAQs

Can I use the 1769-SDN to bridge DeviceNet to Ethernet/IP?

While the 1769-SDN manages DeviceNet traffic, it relies on the CompactLogix controller to route data to other networks. You would pair this with an Ethernet-capable controller (like the 1769-L33ER) to bridge data across different protocols.
Does this module require external power?

Yes. The DeviceNet network itself requires a 24V DC power supply to power the transceiver circuits and any bus-powered devices. The module also draws power from the controller backplane for internal operations.
What is the difference between Series A and Series B?

Series B modules typically feature updated hardware components and improved firmware stability. The 1769-SDN Ser B provides better noise immunity and enhanced compatibility with the latest Studio 5000 Logix Designer environments.
How do I configure the node address?

You configure the node address and scan list using RSNetWorx for DeviceNet. Once configured, the settings reside in the 1769-SDN’s non-volatile memory.
