7. Click Finish.
A confirmation dialog box opens.
8. Click Yes.
The progress dialog box indicates the progress of the firmware upgrade.
The 1756-L7x controllers indicate progress in updates and blocks, where
the 1756-L6x controllers indicate progress only in blocks.
If you are using a 1756-L7x controller and experience a Script File Error after selecting the firmware revision number (see the
example below), there is likely an anomaly with your firmware files.
To recover, take these actions:
• Go to
http://www.rockwellautomation.com/support/ and download the firmware revision you are trying to upgrade. Replace the
firmware revision you have previously installed with that posted on the Technical Support website.
• If replacing your firmware revision does not resolve the anomaly, contact Rockwell Automation Technical Support.

Allow the firmware update to fully complete before cycling power or otherwise
interrupting the upgrade.
If the ControlFLASH upgrade of the controller is interrupted, the 1756-L6x and
1756-L7x controllers revert to boot firmware, that is firmware revision 1.xxx.
