Allen-Bradley 1747-SCNR ControlNet Scanner Module

The Allen-Bradley 1747-SCNR ControlNet Scanner Module provides the essential bridge between a ControlNet network and an Allen-Bradley SLC 500 backplane, enabling ControlNet devices to communicate with an SLC 500 processor. Designed to install in an SLC 500 modular I/O rack, the SCNR functions as the ControlNet scanner within the backplane, handling data exchange between ControlNet nodes and the SLC controller. As part of the 1747 family, this module supports integration of ControlNet into legacy automation environments that use SLC 500 hardware, extending network compatibility without replacing the entire controller. Typical applications include retrofitting or expanding existing SLC 500 systems to connect to ControlNet devices such as remote I/O blocks, sensors, and actuators across the ControlNet network. For proper installation and operation, consult the 1747-SCNR Scanner Reference and the SLC ControlNet installation documentation from Rockwell Automation to confirm compatibility with your specific SLC 500 chassis and addressing scheme.
