Allen-Bradley 1747-SDN DeviceNet Scanner Module

The Allen-Bradley 1747-SDN DeviceNet Scanner Module is a DeviceNet master interface for SLC 500 controllers, enabling the processor backplane to poll up to 63 DeviceNet‑compatible I/O devices on a single DeviceNet network. It plugs into an SLC 500 chassis and is configured with RSNetWorx for DeviceNet, with firmware revision 4.015 associated with this FRN. As the scanner, it manages DeviceNet communications between the SLC 500 CPU and connected slaves, handling data exchange for I/O and control data to field devices. Typical applications include factory automation setups where sensors, actuators, remote I/O modules, and other DeviceNet devices are integrated under a single SLC 500 program.
