Allen-Bradley 1747-SDN SLC 500 DeviceNet Scanner

The Allen-Bradley 1747-SDN DeviceNet Scanner for SLC 500 is the DeviceNet master that bridges an SLC 500 processor with a DeviceNet network, enabling data exchange with multiple DeviceNet slave devices. The module, catalog number 1747-SDN (Series C), installs in any slot of an SLC 500 I/O chassis except the left-most slot that is reserved for the processor. It provides a dedicated DeviceNet port with a 10-pin linear connector for network wiring accessible behind the chassis door. Configuration and commissioning are performed with RSLogix 500 and RSNetWorx for DeviceNet, linking the scanner to the network and mapping I/O data to the controller’s data table. Typical applications include integrating sensors, encoders, and actuators on a DeviceNet network with an SLC 500 control system, where the scanner acts as the network master and polls devices while updating the CPU with I/O data. The module carries standard status indicators to reflect power, network, and module conditions, helping troubleshoot device communication and network health within a legacy or mixed-technology control system.
