It supports 40–48 control network connections, providing a dense bridge for data and control messages between remote ControlNet I\/O racks and a ControlLogix controller, including handling of unscheduled data for efficient I\/O communication. The module offers continuous electrical isolation of 30 V between the ControlNet network and the backplane to help protect the controller and field devices, and it supports bridging between ControlNet A and ControlNet B segments as part of a multi-node ControlNet topology. This module is designed to integrate ControlNet I\/O into a ControlLogix system where deterministic network access is required, and it fits in standard ControlLogix chassis as part of the ControlNet bridge family. Typical applications include expanding ControlNet I\/O in automated manufacturing lines, packaging, and material handling environments where ControlNet devices must communicate with a ControlLogix-based control system.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51658950672686,"sku":null,"price":115.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_967533bc-f174-4bce-9cca-e0be29dfe5f9.jpg?v=1769525838","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1756-cnb-controlnet-communications-bridge-module","provider":"PLG Automation ","version":"1.0","type":"link"}
