Product Dimensions：

Use the 1756-CN2 ControlLogix ControlNet series B module if 

redundant media is not necessary. Applications requiring redundant 

media must use the 1756-CN2R module.

You can use the 1756-CN2R series B modules for standalone or 

redundant control. For standalone control, only one set of modules is 

required. For redundant control, two ControlLogix chassis are 

populated with identical pairs of modules called partners. The chassis 

that performs active control is called the primary chassis and the 

modules in the chassis are called primary modules. The other chassis 

is called the secondary chassis and the modules in the chassis are 

called secondary modules.

These installation instructions discuss both standalone and redundant 

control; read them carefully to distinguish the procedures and 

requirements for each type of control.

The 1756-CN2 and 1756-CN2R series B modules are supported in 

both the local chassis (primary and secondary) and the remote 

chassis (I/O chassis) of a ControlLogix redundancy system, 

revision 16.5x

For more redundancy information, refer to the ControlLogix 

Redundancy System User Manual, publication 1756-UM523F.

If you use redundant control, you must select the same ControlNet 

network address for each set of partner modules (primary and 

secondary). You must also place the partner modules in the same 

corresponding slots in their respective redundant-control chassis 

pair.
