{"product_id":"allen-bradley-1756-cn2-controlnet-communications-bridge","title":"Allen-Bradley 1756-CN2 ControlNet Communications Bridge","description":"\u003cdiv\u003e\u003cp\u003eThe Allen-Bradley 1756-CN2 ControlNet Communications Bridge is a ControlLogix-compatible bridge module that connects a ControlNet network to a ControlLogix controller, enabling deterministic data exchange with remote ControlNet I\/O racks and devices. It serves as the bridge in a ControlNet topology, allowing ControlNet communications to be routed to or from a ControlLogix chassis for distributed I\/O and cross-network messaging. The 1756-CN2 supports up to 128 CIP connections over ControlNet, making it suitable for networks with substantial I\/O traffic or multiple remote nodes. This module is part of Rockwell’s 1756 CNB\/CN2 family of ControlNet bridges and is commonly used when migrating from older CNB\/D hardware or expanding ControlNet capacity within a ControlLogix system. Its role within a modular Allen-Bradley control system is to provide a dedicated interface that consolidates ControlNet traffic for the ControlLogix processor, enabling scalable, centralized control without requiring a complete controller replacement. Typical applications include linking remote ControlNet I\/O racks to a ControlLogix controller, integrating ControlNet devices into a larger Rockwell Automation architecture, and supporting migration paths from CNB-based networks to CN2 for greater connectivity.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":51658951557422,"sku":null,"price":362.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_d7d5ab04-42fa-4ee7-a971-c0069497efa2.jpg?v=1769525856","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1756-cn2-controlnet-communications-bridge","provider":"PLG Automation ","version":"1.0","type":"link"}
