Product Description

The 1747-SDN is a high-performance DeviceNet Scanner Module from the Allen-Bradley SLC 500 series. It serves as the primary interface between an SLC 500 processor (such as the SLC 5/03, 5/04, or 5/05) and a DeviceNet network, enabling communication with up to 63 DeviceNet-compatible devices, including motor starters, drives, photo-eyes, and I/O adapters.

The module supports advanced Change-of-State (COS) and Cyclic I/O modes to optimize network traffic by sending updates only when necessary. Its DeviceNet Pass-Through feature allows direct configuration of field devices via software like RSNetWorx for DeviceNet, eliminating the need for external programming adapters.

Application Scenarios

Distributed I/O: Connects SLC 500 controllers to remote Point I/O or ArmorPoint I/O blocks via DeviceNet.
Motor Control: Interfaces with PowerFlex drives or SMC Flex starters to monitor current, speed, and fault status.
System Bridge: Uses Pass-Through to configure DeviceNet networks without additional PC interface hardware.
High-Speed Sensing: Implements Change-of-State messaging for rapid detection in packaging or sorting lines.

Frequently Asked Questions

Can multiple 1747-SDN modules be installed in a single SLC 500 rack?
Yes, multiple scanners can be installed as long as the total backplane current does not exceed the SLC power supply capacity.

Does the module require a separate power supply for the DeviceNet network?
Yes, the DeviceNet network must have a dedicated 24V DC power source (typically Class 2) to energize both the scanner and connected field devices.
