Parameters without write protection

protection", Section "Parameters with WRITE_NO_LOCK".
The "Restore factory settings" function can also be used when write protection is activated.

Know-how protection

The "Know-how protection" function prevents, for example, confidential company know-how
for configuration and parameter assignment from being read by unauthorized persons.
The know-how protection requires a password. The password must comprise at least 1 and
a maximum of 30 characters.
Note
Password security
You are responsible for the security of your password. Whenever possible, use a password
with sufficient length (min. eight characters); use upper- and lower-case letters and special
characters.
The know-how protection is a pure online function. Therefore, establish a direct connection
to the Control Unit before setting the password.
