IP Address Swapping
These EtherNet/IP modules (and their future revisions) support IP address
swapping in ControlLogix redundancy systems:
• 1756-ENBT, firmware revision 3.1 and greater
• 1756-EWEB, firmware revision 2.2 and greater
During a switchover in ControlLogix redundancy systems, these modules swap
their IP addresses with their partner modules in the other redundant chassis.
For more information about IP address swapping, see the ControlLogix
Redundancy User Manual, publication
