Function

ControlNet network bridging: Provides an interface between the ControlLogix rack and the ControlNet network, supports non-redundant network configuration, and works in conjunction with the Logix5550 controller to control I/O data (planned and unplanned data).

Data bridging: Bridge the ControlLogix backplane data to the ControlNet network to support cross-network data exchange.

High-performance communication: Supports a communication rate of 5 Mbps, suitable for real-time data transmission, and compatible with other ControlNet modules of the Allen-Bradley platform (such as Flex I/O, POINT I/O, SLC, PLC5).

Distributed I/O support: It can be used in distributed I/O architectures, connecting multiple ControlLogix I/O racks to achieve large-scale system integration.

Multi-protocol bridging: Supports data bridging across different protocol networks (such as EtherNet/IP) to enhance system flexibility.

Diagnosis and Monitoring: Status monitoring and fault diagnosis are provided through RSLogix 5000 or Studio 5000 Logix Designer, with module LED display communication and module status.

Modular design: Single-slot module, which can be installed in any slot of the ControlLogix rack, compatible with both standard and redundant power supply configurations.
