{"product_id":"allen-bradley-1756-cnb-controlnet-bridge-module","title":"Allen-Bradley 1756-CNB ControlNet Bridge Module","description":"\u003cdiv\u003e\u003cp\u003eThe Allen-Bradley 1756-CNB ControlNet Bridge Module is a single-slot ControlLogix interface that links a 1756 backplane to a ControlNet network, enabling real-time data exchange between a ControlLogix controller and remote I\/O devices on ControlNet. The module provides a dedicated ControlNet communications path with support for 40–48 ControlNet connections, and it operates over ControlNet’s standard network speed, making it suitable for moderate to large ControlNet deployments. As a bridge, it sits in the local chassis and relays I\/O data to and from the ControlNet network, allowing remote racks to be connected to a ControlLogix system. It is part of the ControlNet Bridge family and is commonly used to integrate field devices such as I\/O modules, sensors, actuators, and drives on ControlNet with a ControlLogix controller, enabling centralized program control and synchronized network timing across the control system. For systems requiring redundancy, the 1756-CNBR is the redundant-bridge counterpart; ensure the correct option matches your backplane architecture and network topology. When configuring ControlNet with this module, use standard Rockwell Automation practices and compatible RSNetWorx for ControlNet tooling to map I\/O and define network parameters.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51657392128302,"sku":null,"price":479.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_cc0b82ba-948c-4a4b-ab3e-c7dd3f4da4e2.jpg?v=1769468496","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1756-cnb-controlnet-bridge-module","provider":"PLG Automation ","version":"1.0","type":"link"}
