Allen-Bradley 1747-SDN SLC 500 DeviceNet Scanner Module

The Allen-Bradley 1747-SDN DeviceNet Scanner Module for the SLC 500 family is a single-slot DeviceNet master that bridges an SLC 500 processor with a DeviceNet network. As the DeviceNet scanner, it polls slave devices on the network and communicates I/O data to the SLC backplane, enabling the controller to read inputs and drive outputs from DeviceNet devices such as sensors, actuators, and I/O modules. Data exchange to the SLC memory is achieved via the M0 and M1 files, aligning DeviceNet data with the PLC program. The module is intended for SLC 5/03 or later processors and supports firmware revisions in the 6.x range, including FRN 6.002, with documentation noting 6.001 or later as a compatibility baseline. Configuration and diagnostics are performed with Rockwell tooling such as RSNetWorx and RSLogix Classic. In typical factory-automation setups, the 1747-SDN serves as the DeviceNet backbone for the chassis, linking DeviceNet devices to the SLC 500 controller for centralized, reliable control.
