Chapter 7 Controller Security
Recover from a Lost
Password
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
Micro830 and Micro850 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.
ATTENTION: The project in the controller will be lost but a new project
can be downloaded.
