It offers dual media redundancy via two BNC connectors and supports 40–48 ControlNet connections, designed to maintain network availability in failover scenarios. As a bridge module, it plugs into a ControlLogix chassis and connects a ControlNet network to the controller, functioning as a communications intermediary for data transfer across the network. The CNBR variant represents the redundant option in the ControlNet bridge family, complementing the nonredundant 1756-CNB and is used in applications where uninterrupted ControlNet communication is critical.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":51658948935982,"sku":null,"price":428.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_8782c539-3ee5-42d1-ae19-1ea913aeadfe.jpg?v=1769525834","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1756-cnbr-control-net-communications-bridge","provider":"PLG Automation ","version":"1.0","type":"link"}
