Update the Configuration in the Logix Designer Application for Redundancy

To update the I/O Configuration tree in the Logix Designer application for redundancy, follow these steps.
IMPORTANT: Do not place I/O modules in a redundant chassis.
  1. If you have I/O modules in the chassis with the controller, add an
    EtherNet/IP™
     communication module.
    1756-EN3TR communication modules are not supported in a redundant chassis.
  2. Because I/O modules must be in a separate chassis, add another
    EtherNet/IP™
     adapter under the adapter you added.
    You can now move the I/O modules to the new chassis in the I/O Configuration tree.
  3. Copy the I/O modules and paste them into the chassis of the newly added communication module.
  4. Delete the I/O modules from the controller chassis configuration.
  5. Move any remote communication from the controller front port to an
    EtherNet/IP™
     module in the local chassis. This step is required because once redundancy is enabled, the front ports on the controller can only be used for Front Port Crossload mode.
  6. Continue by completing the following procedures:
