The Allen-Bradley 1747-SDN DeviceNet Scanner Module is the DeviceNet master interface for SLC 500 systems, mounting in a 1747 backplane within an SLC 500 rack to connect the PLC to a DeviceNet network and coordinate data exchange with slave devices. Designed for SLC 5/02 or later processors, it can poll up to 63 DeviceNet I/O devices, enabling reliable communication with remote sensors, actuators, and I/O blocks across the network. Setup and configuration are performed with RSNetWorx for DeviceNet, where you assign node addresses and map input/output data to ensure proper scanning and data exchange between the 1747-SDN and connected devices in typical manufacturing installations.
