Know-how protection

The know-how protection function (KHP) prevents e.g. strictly confidential company know-
how for configuration and parameter assignment from being read.
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. We recommend that you use a
password with adequate length, which includes upper and lowercase letters and special
characters.
If you set the password via a network connection, then it is possible that unauthorized
persons can "listen in" without being noticed. Therefore, we recommend that you establish a
direct connection to the Control Unit to set the password.
