Installed in a 1756 ControlLogix chassis, the module uses a ControlNet BNC connector for the physical link to the ControlNet bus, enabling data exchange between a Rockwell Automation controller and ControlNet I\/O devices. As a dedicated interface, it handles the protocol translation and network access for remote I\/O and devices on the ControlNet network, allowing you to extend your ControlLogix system beyond its local backplane. Configuration and diagnostics are performed via standard Rockwell software such as RSNetWorx for ControlNet. Common applications include integrating ControlNet-based I\/O and devices (sensors, actuators, remote terminal units) with a ControlLogix controller in manufacturing, batch, or process environments, where centralized control must coordinate multiple ControlNet devices across a plant floor. The 1756-CNB is the baseline ControlNet bridge option in the ControlLogix family, with the CNB designation indicating its role as the ControlNet interface in the backplane-to-ControlNet network bridge.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51657302343982,"sku":null,"price":87.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_61afdca5-3a3b-4f5b-bd8b-dada2a28a018.jpg?v=1769467696","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1756-cnb-controlnet-interface-module","provider":"PLG Automation ","version":"1.0","type":"link"}
