Chapter 11 Controller Security
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.
Configure Controller
Password
To set, change, and clear controller password, see the quickstart instructions Configure
Controller Password on page 276 .
Recover from a Lost
Password
If the controller is secured with a password and the password has been lost, then it becomes
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 Micro830,
Micro850, and Micro870 controllers, the 2080-LCD for Micro810 controllers, or the 2080-
REMLCD for Micro820 controllers. Then, ControlFLASH™ 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.
Using the Memory Module
Plug-in
You can use the memory module (2080-MEMBAK-RTC and 2080-MEMBAK-RTC2) to download a
program into different controllers.
Back up the project
To perform a project backup from a controller to the memory module, follow these steps:
1. Create a new program and choose the desired controller.
The Micro850 controller is used for this example.
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.
IMPORTANT In Connected Components Workbench software version 20.01.00 or
later, if the same password is removed and restored back on the new
Micro850 (2080-L50E) and Micro870 (2080-L70E) controllers, the
backup copy of the program in the 2080-MEMBAK-RTC2 plug-in module
must be updated before it can be used to restore the program.
Otherwise the restore fails as the internal encryption code changes
once the password is removed.
IMPORTANT After creating or changing the controller password, you need to power
down the controller in order for the password to be saved.
ATTENTION: The project in the controller will be lost but a new project can
be downloaded.
IMPORTANT 2080-MEMBAK-RTC is not supported on Micro850 (2080-L50E) and
Micro870 controllers.
