The Allen-Bradley 1756-CNBR, or ControlNet Bridge Redundancy, is an interface module used for communicating 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 port while the 1756-CNB only has one, although both of them have 1 ControlNet RJ45 port.
Like the non-redundant module, the 1756-CNBR also controls scheduled data in conjunction to the Logix5550 Controller and bridges unscheduled data between the ControlLogix backplane and the ControlNet Network.
To prevent communication loss when a tap or trunkline is disconnected, a redundant ControlNet media can be used. For that connection, the only module you can use is the 1756-CNBR.
The technical specifications of this module are also similar to the non-redundant module. It can also handle up to 64 bidirectional scheduled and unscheduled connections with other ControlNet devices. Aside from that, up to 20 buffers for unconnected messages can be supported by the module. Also, this is the module needed if your application has 40 to 48 Logix communication connections per communication module and the communication rate is 5 megabytes per second. It also has 99 nodes available.
The current draw for the 1756-CNBR is 970 milliamperes at 5.1 Volts DC and 1.7 milliamperes at 24 Volts DC.
Before making your connection, make sure to check the tap drop cable for the label indicating the attached segment. This is to make sure that the tap connections will not be accidentally reversed. If not, these reversals will require troubleshooting and the status will be displayed incorrectly.
