Allen Bradley 1756-CN2R/B ControlLogix Communication Module

The Allen-Bradley 1756-CN2R/B is a ControlLogix ControlNet Redundant Bridge that provides a number of advantages, including redundancy, performance, reliability, and ease of use. It is a versatile communication module that can be used in a variety of applications.It is used to create and maintain a redundant ControlNet network between two ControlLogix controllers. This ensures that the network remains operational if one of the controllers fails.The 1756-CN2R/B is typically used to provide redundant connectivity between a ControlLogix controller and a ControlNet network. It can also be used to provide redundant connectivity between two ControlNet networks.To use the 1756-CN2R/B, simply connect it to two separate ControlNet networks using ControlNet cables. Then, configure the 1756-CN2R/B to use the desired ControlNet baud rate and ControlNet cable type.Once the 1756-CN2R/B is configured, it will begin automatically monitoring the two ControlNet networks. If one of the ControlNet networks fails, the 1756-CN2R/B will automatically switch to the other ControlNet network to maintain communication.
