Controller Security
Micro800 security generally has two components:
• Exclusive Access that prevents simultaneous configuration of the
controller by two users
• Controller Password Protection that secures the Intellectual Property
contained within the controller and prevents unauthorized access
Exclusive Access Exclusive access is enforced on the Micro800 controller regardless of whether
the controller is password-protected or not. This means that only one
Connected Components Workbench software session is authorized at one
time and only an authorized client has exclusive access to the controller
application. This ensures that only one software session has exclusive access to
the Micro800 application-specific configuration.
Exclusive access is enforced on Micro800 firmware revision 1 and 2. When a
Connected Components Workbench software user connects to a Micro800
controller, the controller is given exclusive access to that controller.
Password Protection By setting a password on the controller, a user effectively restricts access to the
programming software connections to the controller to software sessions that
can supply the correct password. Essentially, Connected Components
Workbench software operation such as upload and download are prevented if
the controller is secured with a password and the correct password is not
provided.
Micro800 controllers with firmware revision 2 and later are shipped with no
password but a password can be set through the Connected Components
Workbench software (version 2 or later).
In Connected Components Workbench software version 10 or later, a stronger
password algorithm is introduced to provide better security. To take full
advantage of this enhancement, the Micro800 controller must have firmware
revision 10 or later, and the project must also be software version 10 or later.
The controller password is also backed up to the memory backup module (that
is, 2080-MEMBAK-RTC2 for Micro830, Micro850 and Micro870; 2080-
MEMBAK-RTC for Micro830 and Micro850; 2080-LCD for Micro810; and
microSD card for Micro820 controllers).
