Upgrade by Using Redundancy
System Update
You can upgrade an enhanced redundancy system revision to another while your
process continues to run. This is known as Redundancy System Update (RSU).
Complete these steps to upgrade your redundancy system from one enhanced
redundancy system revision to another enhanced redundancy revision while
your process continues to run.
1. Step 1: Before You Begin
2. Step 2: Upgrade the Workstation Software
3. Step 3: Download and Install the Redundancy Firmware Bundle
4. Step 4: Upgrade the Redundancy Module Configuration Tool
5. Step 5: Add the EDS Files
6. Step 6: Prepare the Redundant Chassis for the Firmware Upgrade
7. Step 7: Upgrade the Primary Chassis Redundancy Module Firmware
8. Step 8: Upgrade the Secondary Redundancy Module Firmware and All
Other Modules’ Firmware in the Secondary Chassis
9. Step 9: Prepare the RSLogix 5000 Project for the Upgrade
10. Step 10: Lock the System and Initiate a Switchover to Upgrade
11. Step 11: Upgrade the New Secondary Chassis Firmware
12. Step 12: Synchronize the Redundant Chassis
IMPORTANT RSU is available only when upgrading from an enhanced redundancy system revision
to another. You cannot use this process to upgrade from a standard redundancy
system to an enhanced redundancy system.
IMPORTANT Any Ethernet communication modules that have the rotary switch set must first be
updated using the
