8. PROTECTION: PASSWORD AND DIGITAL SIGNATURE MANAGEMENT
The c.pCO controller implements protection methods aimed at
preventing unauthorised personnel from performing certain sensitive
operations like updating the software, accessing the system menu,
cloning proprietary software, etc.
It is possible to protect the c.pCO controller by setting a password or
a digital signature. Signing the controller by digital signature is an
irreversible process, while the password can be modified or cancelled.
The password is applied by default in the c.suite development tool, while
the digital signature is an additional function enabled with a dedicated
license.
