Industrial producers can improve their network resiliency by using primary and backup adapters for the 1756-EN4TR ControlLogix EtherNet/IP communications module. This redundant-adapter functionality is provided through a firmware update to the communication module. Because of the update, when used with ControlLogix controllers and redundant switches, the communication module no longer is a single point of failure. The firmware enhancement can be used with a single ControlLogix controller or redundant controllers. It also can be used with star or device-level ring (DLR) architectures. It also allows an existing 1756 I/O chassis to be modified for redundant adapters. Slots 0 and 1 are used for the redundant adapters.
