Important:
For an enhanced redundancy system, you must use a 1756-CNB,
1756-CNBR, 1756-CN2 series B, or 1756-CN2R series B communication module. The 1756-CN2 or 1756-
CN2R series A module does not support enhanced redundancy. For more information, refer to the
ControlLogix Enhanced Redundancy System User Manual, publication 1756-UM535
