Opening a program block in the window

You can display all the logic and graphical information of a program block.

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.
