The Allen-Bradley 1756-CNBR, or ControlNet Bridge Redundancy, is an interface module used to communicate within a ControlNet network. It is the same as the 1756-CNB, but the biggest difference is that the 1756-CNBR has an additional ControlNet port, which will support redundant media. This module has 2 ControlNet BNC ports while the 1756-CNB only has one, although both have 1 ControlNet RJ45 port. Like the non-redundant module, the 1756-CNBR also controls scheduled data in conjunction with the Logix5550 controller and bridges unscheduled data between the ControlLogix backplane and the ControlNet network.
The Allen-Bradley 1756-CNBR is a ControlNet Bridge module. This module is part of the ControlLogix product family used to interface to a ControlLogix controller or implement distributed I/O architecture over the high-speed ControlNet network. This module has two (2) ControlNet ports, allowing connection to standard (simplex) and redundant ControlNet networks.
The 1756-CNBR supports a transmission rate of 5 Mbps, which is the standard transmission rate of the ControlNet protocol. It uses quad-shielded RG-6 coaxial cable as the trunk cable and a connection established to the trunk cable using ControlNet jacks. This module supports 40-48 logical communication connections and a maximum of 64 connections. The maximum number of nodes supported by the 1756-CNBR is 99 nodes.
The 1756-CNBR can be installed along the ControlLogix processor as a local communication module or in any distributed I/O rack as a headend communication module. It is compatible with a variety of ControlLogix racks such as the 1756-A4, 1756-A7, 1756-A10, 1756-A13, and 1756-A17. It can be installed in any available slot and requires only a single slot in the chassis. It can also be used with standard and redundant power supplies.
