Preface
Summary of Changes This table contains the changes that were made to this revision.
Overview This publication provides instructions for replacing modules or updating
firmware in a powered-up and running redundancy system.
The following requirements must be met:
• The redundancy system is being updated to redundancy revision
24.052_kit1 or later.
• If doing online updates, you must go in the following revision order:
V20.05x > V24.052 > V30.051 (or later version in V30) > V31.052
(or later version in V31)
• Online updates are only permitted for updates from revision 20.054 or
later.
• Online updates are only permitted with a ControlLogix® 5570
controller (in both the previous release and the new release, in both the
primary and secondary chassis).
• A replacement ControlLogix 5570 controller must have memory equal
to or greater than the memory in the partner ControlLogix 5570
controller.
You can access release notes for each redundancy firmware revision from the
Rockwell Automation Product Compatibility and Download Center
(PCDC). Go to http://www.rockwellautomation.com/global/support/
pcdc.page, and search for your redundancy firmware revision.
In a redundant system, modules can be replaced, and firmware can be updated
using either of the following methods:
•Method 1: Modules are replaced and firmware is updated while the
redundancy system is powered up and the controllers are left in RUN
mode. In this case, this publication applies.
•Method 2: If you power down the redundancy system or take
controllers out of RUN mode to replace modules, then this method is
similar to a new installation and this publication does not apply. Instead,
see the ControlLogix Redundancy User Manual, publication
1756-UM535, and install the modules, firmware, and application
software versions for the appropriate revision for your installation.
Compatible module firmware revisions and software versions are listed
in the Release Notes for the appropriate redundancy firmware revision.
For instructions to update to revisions previous to 24.052_kit1, see the
appropriate Release Notes in the PCDC at:
http://www.rockwellautomation.com/global/support/pcdc.page.

Update Considerations
Before You Begin When updating products in a ControlLogix® redundancy system, you must:
• Download and install the appropriate redundancy firmware bundle, and
the compatible versions of the Studio 5000 Logix Designer® application,
RSLinx® Classic, ControlFLASH™ or ControlFLASH Plus™ software,
and the Redundancy Module Configuration Tool (RMCT)
• Update the firmware on the redundancy modules, controllers, and
communication modules in the redundancy chassis pair.
• Update the revision of controller and communication module firmware
in the redundancy application project.

IMPORTANT If you are migrating from an existing revision 30.051 redundancy
application, use Studio 5000 Logix Designer version 30.01.00 or newer.
Version 30.00.00 has a known anomaly (Lgx00191976) that prevents you
from uploading redundancy projects to a new file, which can interfere with
the update process.

8Rockwell Automation Publication 1756-RM010C-EN-P - August 2018
Chapter 1 Update Considerations
LINT Members Must Align on 8-byte Boundaries
Beginning with version 27 of the Studio 5000 Logix Designer application,
LINT members must be aligned on 8-byte boundaries, and User-defined Data
Types (UDT) that contain LINT members must be sized as a multiple of 8
bytes.
This change impacts your Logix Designer application project if any of the
following situations are true:
• You migrate a standard project, version 26 or earlier, to a redundancy
project that is version 30.051 or later, and you have LINT tags inside a
UDT.
• You migrate a redundancy project, version 24.052 or earlier, to a project
that is version 30.051 or later, and you have LINT tags inside a UDT.
• You use a tag with LINT members as a producer, and at least one
consumer (controller) has firmware earlier than version 27.
• You use a tag with LINT members as a consumer, and the producer
(controller) has firmware earlier than version 27.
For more information, see these resources:
•Align LINT Members on 8-byte Boundaries on page 51
• Logix Designer online help topic: ‘LINT data types within this tag now
align on 8-byte boundaries. Check produce/consume connection’.
IMPORTANT If you have User-defined Data Types (UDT) that contain LINT members, you
may not be able perform the online Redundancy System Update. See the
ControlLogix Redundancy User Manual, publication 1756-UM535, on how to
install and update the modules, firmware, and application software versions
while offline.
IMPORTANT If you attempt to perform a Redundancy System Update from version 24.05x
to version 30.051 or later, and you have LINT tags inside a UDT, the Lock for
Update attempt can fail.

Rockwell Automation Publication 1756-RM010C-EN-P - August 2018 9
Update Considerations Chapter 1
I/O Modules in Redundancy Systems
In a redundancy system, you can use only I/O modules in a remote chassis. You
cannot use I/O modules in the redundant chassis pair.
This table describes the I/O modules that redundancy systems support.
Verify Your RMCT Version
Complete these steps to check or verify the version of the RMCT you have
installed.
1. Launch RSLinx Classic software.
2. Click the RSWho icon.

IMPORTANT If you have RMCT version 7 or earlier, it does not support the 1756-RM2
modules. more information on the RMCT, see Knowledgebase article 29511.
IMPORTANT You must uninstall any existing version of the Redundancy Module
Configuration Tool (RMCT) before you install the RMCT, version 8.4.1.0 or
later. If you do not uninstall the previous version, you can have difficulty if
you try to uninstall version 8.4.1.0 or later at another time.
TIP If Module Configuration is not available in the list of options, RMCT version 8
has not been installed.

3. Right-click your redundancy module and choose Module
Configuration.
The Module Configuration dialog box opens.
4. Right-click the title bar and choose About.
The About dialog box opens and indicates the RMCT version.
TIP The RMCT launches at the version that is compatible with the 1756-RM2
or 1756-RM2XT 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 cannot reflect the new
RMCT version.

Update Considerations Chapter 1
Download and Install
ControlFLASH Software
If you are upgrading to redundancy firmware revision 30.051 or 31.052,
ControlFLASH software is not included in redundancy firmware revision kits.
You must download it separately.
To update to redundancy firmware revision 30.051 or 31.052, you must use
ControlFLASH version 15.01.00 or later, or ControlFlash Plus version
1.01.00 or later.
For information on how to download and install ControlFLASH or
ControlFLASH Plus software, see:
• ControlFLASH Firmware Upgrade Kit User Manual, publication
1756-UM105
• ControlFLASH Plus Quick Start Guide, publication CFP-QS001
Download the Redundancy
Firmware Bundle and RMCT
To download the appropriate redundancy firmware bundle, follow these steps:
1. Go to http://www.rockwellautomation.com/global/support/firmware/
overview.page.
2. Search for “Enhanced Redundancy”.
IMPORTANT If you are only upgrading to redundancy firmware revision 24.052, the
compatible version of ControlFLASH software is included in redundancy
firmware revision 24.052_kit1. However, ControlFLASH 14.01.00 is
compatible with redundancy firmware revision 24.052.

Update Considerations Chapter 1
The RMCT is included in the downloads for most redundancy bundles. For
redundancy bundles that use firmware revision 20.009 or later for 1756-RM2
modules, the RMCT is included in the redundancy bundle and is not available
for separate download.
For redundancy bundles that use firmware revision earlier than 20.009, you can
download the RMCT separately as a product add-on:
1. Go to http://www.rockwellautomation.com/global/support/firmware/
overview.page.
