5. Enter the new password in the "New password" field. Enter the same password in the
"Confirm password" field.
6. Click "OK" to confirm your entry.
7. Close the "Know-how protection" dialog by clicking "OK".
Result: The blocks selected will be know-how-protected. Know-how protected blocks are
marked with a lock in the project tree. The password entered applies to all blocks selected.
Opening know-how protected blocks
1. Double-click the block to open the "Access protection" dialog.
2. Enter the password for the know-how protected block.
3. Click "OK" to confirm your entry.
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 next time the block is opened. If you close the "Access protection" dialog with "Cancel",
the block will open but the block code will not be displayed and you will not be able to edit
the block.
The know-how protection of the block is not removed if, for example, you copy the block or
add it to a library. The copies will also be know-how-protected.
