Products Description
Use your fingers or a small screwdriver to set the network address switches for the module. For modules in a standalone chassis, you must specify a unique ControlNet network address; for modules in a redundant chassis, you must specify the same address for the secondary module that you specified for the corresponding primary module Determine Module Slot Location
The figure Chassis Slot Numbering shows chassis slot numbering in a 4-slot chassis. Slot 0 is the first slot and is always the leftmost slot in the rack (the first slot to the right of the power supply). You can use any size ControlLogix chassis and install the module in any slot. You can also install multiple ControlNet modules in the same chassis. You can install as many modules as your power supply can accommodate (such as the number for which the power supply is rated). Chassis Slot Numbering Install the Module You can install or remove a module while chassis power is applied. Follow these steps to install the module.
1. Align the circuit board with top and bottom guides in the chassis.
2. Slide the module into the chassis.
Make sure that the module backplane connector properly connects to the chassis backplane as shown. You can select an address of 01 to 99 for modules in a standalone chassis or 01… 98 for modules in redundant chassis. 00 is an invalid ControlNet network address. IMPORTANT If you plan to install a redundant system, you must place the primary and redundant modules in the same corresponding slot in their respective chassis. For example, if you place a 1756-CNBR module in slot 3 (from the left) in the primary chassis, you must also place a 1756-CNBR module in slot 3 in the redundant chassis
The Allen-Bradley 1756-CNB or ControlNet Bridge module is an interface module used for interfacing a ControlLogix rack to ControlNet network. Compared to the Allen-Bradley 1756-CNBR module, the 1756-CNB is used in standard, non-redundant configuration. This module is perfect if the user applications have 40 to 48 Logix communication connections per communication module. It has a communication rate of 5 megabytes per second and it has 99 nodes available. The 1756-CNB module handles 2 things, namely the control of I/O data when it is used with a Logix5550 controller for scheduled data and for unscheduled data, bridging data between the ControlLogix backplane and the ControlNet Network. Make sure that the path information is correct in order to properly route the messages it receives.
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.
