AB 1756-CNBR/E
The A-B 1756-CNBR/E module is A ControlNet network redundancy bridge module designed by Rockwell Automation (Allen-Bradley) for its ControlLogix series PLC. It is mainly used to establish redundant connections in the ControlNet network to improve network reliability and fault tolerance.
Main function
Redundant connection: Create two independent network segments in the ControlNet network and connect them through this module for redundant backup.
Failover: When a network segment fails, the module automatically switches to another network segment to ensure the continuous running of the network.
Improved reliability: The redundant design significantly improves the reliability of the ControlNet network and reduces system downtime.
Enhancing network performance: Improves the overall network performance by means of load balancing.
