Chapter 9 Controller Security
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 to download a program into different
controllers. Make sure that the module is compatible with the Micro800
controllers. The 2080-MEMBAK-RTC2 module is compatible with Micro 830,
Micro850, and Micro870 controllers. The 2080-MEMBAK-RTC module is
compatible with Micro830 and Micro850 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.
ATTENTION: The project in the controller will be lost but a new project
can be downloaded.
