Rockwell 1788-CN2FFR Series B Redundant FF Linking Device

Allen-Bradley 1788-CN2FFR Series B ControlNet to FOUNDATION Fieldbus Linking Device

Product Overview

The 1788-CN2FFR (Series B) is a high-performance, redundant linking device manufactured by Rockwell Automation. It serves as a critical bridge between ControlNet networks and FOUNDATION Fieldbus (FF) H1 segments. Engineered for the process industry, the 1788-CN2FFR allows Logix-based controllers to seamlessly interface with intelligent field instrumentation, supporting asset management and advanced diagnostics. This device is specifically designed for high-availability architectures, featuring dual ControlNet ports to ensure continuous data flow even in the event of a media failure. It essentially translates complex Fieldbus device data into a format accessible by ControlNet scanners, facilitating a unified control strategy.
