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.

The ladder diagram display (LAD) is opened.

Select the relevant program organizational unit (POU) in the overview

and press the "Program block" softkey.

Press the "Protection" softkey.

The "Protection" window appears.

Enter your password and press the "Accept" softkey.
