{"product_id":"allen-bradley-1756-cnb-controlnet-communications-module","title":"Allen-Bradley 1756-CNB ControlNet Communications Module","description":"\u003cdiv\u003e\u003cp\u003eThe Allen-Bradley 1756-CNB ControlNet Communications Module is a ControlNet bridge module for Rockwell Automation's ControlLogix platform, delivering a dedicated ControlNet interface that connects a ControlNet network to a 1756 backplane in ControlLogix systems and enables scalable network expansion across multiple racks and remote I\/O. Powered directly from the ControlLogix backplane, it enables deterministic data exchange between ControlNet devices and the Logix processor by bridging ControlNet traffic to remote I\/O racks, routing status and I\/O data, and supporting efficient integration with the broader automation architecture. Firmware revision F 11.003 is associated with this hardware listing, indicating the specific feature set and compatibility for this generation of the module within contemporary ControlLogix configurations. Typical applications include integrating remote ControlNet I\/O into a ControlLogix process control system, bridging legacy ControlNet devices with modern Logix controllers, and enabling distributed, time‑deterministic communications across ControlNet networks in manufacturing, packaging, and process automation environments.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51657302311214,"sku":null,"price":22.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_08dced48-20df-44b5-9c26-c2c912e38fd7.jpg?v=1769467696","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1756-cnb-controlnet-communications-module","provider":"PLG Automation ","version":"1.0","type":"link"}
