Result: The know-how-protected block will open.
Once you have opened the block, you can edit the program code and the block interface of
the block for as long as the block or TIA Portal is open. The password must be entered again

the block.

add it to a library. The copies will also be know-how-protected.

block may not be open in the program editor.

protection" dialog.
