Opening know-how protected blocks
To open a know-how protected block, follow these steps:
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 is 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 STEP 7 is open. You must enter the password again the
next time you open the block. If you close the "Access protection" dialog with "Cancel", you
will be able to open the block but you cannot display the block code or edit the block.
If you copy the block or add it to a library, for example, this does not cancel the know-how
protection of the block. The copies will also be know-how-protected.

protection" dialog.
