8. Complete steps 2 … 7 for each module in the secondary chassis, including a
new controller, if applicable.
Once you have upgraded the firmware for each module in the secondary chassis,
prepare the RSLogix 5000 project for the upgrade.
Step 9: Prepare the RSLogix 5000 Project for the Upgrade
Complete these steps to prepare the RSLogix 5000 program and controllers for
the upgrade.
1. Launch RSLogix 5000 software and go online with the primary controller.
2. Verify that the watchdog time is set to a value that corresponds with the
requirements of the enhanced redundancy system revision and your
application.
See Minimum Value for the Watchdog Time on page 177 for information
about calculating the minimum watchdog time.
3. Cancel or assemble any pending test edits.
4. Remove all Sequential Function Chart (SFC) forces from the project.
5. Verify that no changes need to be made to the following:
– I/O forces
– I/O configuration
After this step, changes to I/O cannot be made until after the enhanced
redundancy system revision upgrade is complete and both chassis are
synchronized.
6. If you are upgrading an enhanced redundancy system, revision 16.81 or
earlier, disable CST Mastership.
7. Configure the controllers and communication modules in the redundant
chassis pair as necessary.
8. Save the project.
9. Go offline.
10. Click Controller Properties.
IMPORTANT Ethernet communication modules that have rotary switches set must have been
previously updated using
