Back Up and Restore a Password-Protected Controller

In this workflow, user application will be backed up from a Micro800 controller that is locked to a
memory plug-in device.
1. In the Project Organizer, select the Discover icon.
The Browse Connections dialog appears.
2. Select the target controller.
3. When requested, enter the controller password.
4. Back up controller contents to the memory module.
The project in the memory module is now password locked.
5. Remove the memory module from controller1 and insert into controller2.
6. Restore contents from the memory module to controller2.
This operation succeeds only if:
• The controller has no password – the project can be restored to the controller by
setting the "Load on power up" option for the memory module to Load Always.
• The controller's password matches the project's password.
IMPORTANT Even though the password matches, the restore operation will fail if either
one of the controller or project in the memory module is protected using the
old password algorithm, and the other is protected using the new password
algorithm. You can flash update the controller using the Reset option to clear
the password before restoring the project to the controller.
To set, change, and clear controller password, see the quickstart instructions
Password on page 125.
If the controller is secured with a password and the password has been lost, then it is impossible to
access the controller using the Connected Components Workbench software.
To recover, the controller must be set to Program Mode using the keyswitch for Micro850 and
Micro870 controllers, or the 2080-REMLCD module for Micro820 controllers. Then, ControlFLASH™
software can be used to update the controller firmware, which also clears the controller memory.
In Connected Components Workbench software version 10 or later, the Reset option must be
selected for the controller memory to be cleared during the firmware update. If the Upgrade or
Downgrade option is selected, the password is retained.
ATTENTION: The project in the controller will be lost but a new project can
be downloaded.
