Deactivate password protection/change password
The password protection is simply activated by deleting the set password. If you want to change the
set password, first delete the set password as well. Then set the new password.

How to delete the set password:
1. Enter the set password in C00505/3 .
2. Execute "Delete password" device command C00002/33 = "1: On / start"
• After a successful deletion, password status OFF is displayed in C00505/3 .
2.4.2 Individual password protection for single communication channels
This function extension is available from version 15.00.00!
The 8400 TopLine can be parameterised via the following "communication channels":
• Internally via system blocks ( LS_ParReadWrite1-6 and LS_WriteParamList )
• externally via
• Diagnostics interface X6 ("DIAG")
• CANopen interface X1 ("CAN on board")
• Fieldbus interface (MCI)
As in some applications, only certain communication channels have to be protected, the parameters
described in the following serve to configure individual access restrictions for each communication
channel.
In the Lenze setting, all access restrictions are active for all communication channels when the
password is set. This corresponds to the previous behaviour with a set password, i.e. only one
write/read access to the parameters of the user menu is possible.

Note!
The configuration can only be changed if no password has been set!
• This means that even if the password has been deactivated temporarily by the "check
password" device command, the configuration cannot be changed.
• As long as a password is set, the "Load Lenze setting" device command does not
change the configuration either.
The password protection is activated by setting a password.
