Prepare for an Online Firmware Update
Before you update firmware, complete these tasks:
- Download and install the compatible versions of theStudio 5000 Logix Designer®application, communication software, andControlFLASH Plus®software.ControlFLASH Plus®software updates the module firmware. For information on how to useControlFLASH Plus®software, see the ControlFLASH Plus Quick Start Guide, publication CFP-QS001.
- Understand the migration paths for your system.SystemResourceControlLogix®5590 redundancy
- Understand the redundant chassis requirements.
- Download and install the redundancy firmware bundle.
Verify the RMCT Version
The Redundancy Module Configuration Tool (RMCT) launches at the version that is compatible with the redundancy module firmware that is installed. You must update your RMCT version and the redundancy module firmware revision so it is compatible with the new RMCT version. If you do not perform this update, the About dialog box will not reflect the new RMCT version.
To verify the installed version of the RMCT, complete these steps.
- Right-click the title bar and choose About.The version that appears on the About dialog box is the earliest RMCT version that you need based on your bundle.
Prepare the Controller Project for the Update
Use the following procedure to upgrade to a major controller firmware revision, upgrade to a controller with more memory, or upgrade a communication module.
To prepare the controller project and controllers for the update, complete these steps.
- Start the Logix Designer application and select your redundancy project.
- Go online with the primary controller.
- To make sure that your offline project has the latest updates, or in case you do not have an offline file, upload the project from the primary controller.
- If safety-locked, safety-unlock the controller.
- Cancel or assemble any pending test edits.
- Remove all sequential function chart (SFC) forces from the project.
- Verify that no changes are required for the following:
- I/O forces
- I/O configuration
IMPORTANT:After this step, changes to I/O cannot be made until after the redundancy system revision update is complete and both chassis are synchronized. - Save the project.
- Go offline.
- If the project is a Logix SIS project and the project has a safety signature, delete the safety signature.IMPORTANT:To move to another firmware revision, the project must be unlocked with no safety signature. If needed, keep a copy of the original signed project for your records.

- Open the controller properties and select Change Controller on the General tab.
- Specify the controller catalog number and controller revision that you are upgrading to.
- If you install a new controller while updating the secondary chassis firmware, specify the new controller catalog number and select OK.
- For each communication module in the chassis, access the module properties and select the target firmware revision.
- Save the project.
- Proceed to Update Redundancy System Firmware.
