Allen Bradley 1747-SCNR/A SLC 500 ControlNet Scanner

Product Introduction

The Allen-Bradley 1747-SCNR/A ControlNet Scanner is a dedicated communication module designed for SLC™ 500 programmable controller systems, providing high-speed, deterministic data exchange over ControlNet networks. Acting as the network scanner, this module manages scheduled and unscheduled messaging between the SLC 500 controller and distributed ControlNet devices.

The 1747-SCNR/A enables real-time control and synchronized data transfer, making it suitable for applications where timing accuracy, repeatability, and coordinated control are critical. By integrating ControlNet communication directly into the SLC 500 architecture, it allows controllers to interface efficiently with remote I/O, drives, and other intelligent devices.

This scanner module is widely used in industrial systems that require deterministic network performance while maintaining compatibility with established Allen-Bradley control platforms.
