Designed for high-availability applications, the CNBR provides dual pathways for ControlNet traffic, allowing failover without interrupting I\/O data. Installed in a 1756 backplane, it manages ControlNet messaging and I\/O data exchange between the PLC and ControlNet devices, enabling seamless integration of ControlNet peripherals with a ControlLogix controller. The module supports 40-48 ControlNet connections, accommodating typical ControlNet topologies and device counts; it is part of Rockwell's ControlNet Bridge family and complements the standard 1756-CNB when redundancy is required. The CNBR works with standard ControlLogix racks and is configured through Rockwell software tools to map I\/O and communications on the ControlNet network, including enabling redundant network paths and recovery during a link failure. Common applications include industrial automation setups requiring deterministic I\/O data exchange with ControlNet devices, such as remote I\/O across a plant floor, or bridging legacy ControlNet devices into a modern ControlLogix control environment. This module is designed for industrial environments and supports integration with existing ControlNet topologies while providing the reliability benefits of redundancy, helping minimize downtime in critical processes.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":51659693228334,"sku":null,"price":30.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_4e396eaf-7e50-4eac-b20b-c435db7e9e3f.jpg?v=1769529734","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1756-cnbr-controlnet-bridge","provider":"PLG Automation ","version":"1.0","type":"link"}
