The 1756-CNB is an communication adapter that functions as a ControlNet Bridge. It is provided with an integrated ControlNet interface such as One (1) BNC connector for non-redundant media operation and One (1) NAP (RJ-45 8-pin with shield).
Up to 64 bidirectional connections with other ControlNet devices can be supported by the 1756-CNB module. It can be a mix of both scheduled and unscheduled connections. However, the number of supported connections also depends on the network configuration. If an application needs more connections, the users can add another 1756-CNB module, but they must make sure to do it in the same chassis and on the same network as the first module. It can also support up to 20 buffers for unconnected messages. It also has 2 ports - 1 ControlNet BNC port and 1 ControlNet RJ45 port. The users need to set the module’s node address switches first when installing the 1756-CNB module. They can select a unique node address from 01 to 99. The users can then use the module as a standalone control module by using 1 set of modules or as a redundant control setup by using identical pairs of modules (partners). Note that when using redundant control, the node address switches should have the same node address. The 1756-CNB current draw at 5.1 Volts DC is 970 milliamps and 1.7 milliamps if the current draw is at 24 Volts DC. Its power dissipation is rated at 5.14 Watts.
