Allen-Bradley 1747-SDNGM DeviceNet Scanner Module

Allen-Bradley 1747-SDNGM DeviceNet Scanner Module is a DeviceNet master module designed for Rockwell’s SLC 500 racks, acting as the bridge between a backplane-mounted SLC processor and a DeviceNet network. It functions as the network scanner/master, enabling the SLC controller to poll and communicate with DeviceNet slaves. The module is powered from 5 VDC and typically draws up to 500 mA from the backplane. It can manage up to 63 DeviceNet devices on the network, providing centralized I/O data collection and control through the scanner. Configuration is performed with RSNetWorx for DeviceNet, and device parameters are configurable via explicit messaging (M0 and M1) as documented in the 1747-SDN installation and user manuals, with the numeric display indicating the 1747-SDN/SDNGM node address on the DeviceNet network. This product family is recognized by ODVA as the 1747-SDN Scanner Module for DeviceNet, confirming its role within the SLC 500 ecosystem and its compatibility with standard DeviceNet practices.
