Update Redundancy System Firmware

WARNING:
While you complete the process to update redundancy system firmware, there is a loss of redundancy. The controller runs the machinery without a backup until the update is complete.
You can update redundancy firmware to another revision while your process continues to run. Before you update your redundancy system to a new revision, consider the following:
  • During the update procedures, you cannot use the Logix Designer application to change the mode of the controller. Instead, use the mode switch on the front of the controller.
  • Remember the following when completing the tasks described in the rest of this section:
    • Do not change the project other than with changes that are identified in these tasks.
    • Verify that no one else is also changing the project.
    • Do not use a
      FactoryTalk®
       Batch server to change equipment phase-states when upgrading your redundancy system.
To update your running redundancy system, complete this process.
  1. Prepare the redundant chassis for the firmware update.
  2. Update the redundancy module firmware in the secondary chassis.
  3. Update the redundancy module firmware in the primary chassis.
  4. Update other module firmware in the secondary chassis.
  5. Lock the system for update and initiate a locked switchover.
  6. Update other module firmware in the new secondary chassis.
  7. Synchronize the redundant chassis.
