24.14 Displaying/canceling the access protection
You can password protect your program organizational units (POUs) in the PLC 828
programming tool. This prevents other users from accessing this part of the program. This
means that it is invisible to other users and is encrypted when it is downloaded.
A lock symbol is used to show a password-protected POU in the block overview and in the
ladder diagram.
