The module supports 40–48 ControlNet connections, enabling a sizable ControlNet topology to be serviced from a single ControlLogix chassis. It bridges unscheduled data, including messaging and programming information, between the ControlLogix backplane and the ControlNet network, helping to segregate control traffic and extend distributed I\/O to ControlNet devices. Designed for industrial automation environments that require integrating ControlNet networks with ControlLogix controllers, the 1756-CNB plugs into a 1756 ControlLogix backplane and communicates with ControlNet-equipped devices across the network to coordinate I\/O, device messaging, and networked control. As part of the 1756 ControlLogix module family, this bridge provides a centralized gateway for ControlNet connectivity, enabling scalable deployment in facilities that rely on ControlNet for distributed I\/O while maintaining a single, controller-centric management plane.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51657302376750,"sku":null,"price":73.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_1e366706-ef51-40f9-9503-ff9cd1f06b7f.jpg?v=1769467697","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1756-cnb-controlnet-communications-bridge-plc-module","provider":"PLG Automation ","version":"1.0","type":"link"}
