Allen-Bradley 1747-SDN DeviceNet Scanner Module is a backplane-mounted interface for the SLC 500 family that enables an SLC 500 controller to communicate with DeviceNet devices on the network. It carries firmware release number FRN 9.001 and is part of the Series B 1747-SDN lineage, designed to scan a DeviceNet network and present I/O data to the PLC. Rockwell Automation lists the 1747-SDN as discontinued as of March 31, 2024, and it is no longer available for sale through official channels. In typical use, the module acts as the DeviceNet scanner on an SLC 500 rack, bridging DeviceNet devices—such as sensors, actuators, and I/O devices—to the controller for real-time data exchange.
