7.4 Know-how protection
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 opens.
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", the
block will open but the block code will not be displayed. It is not possible to 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.
Changing block know-how protection
Proceed as follows to change block know-how protection:
1. Select the block for which you want to change know-how protection. The protected block
must not be open in the program editor.
2. In the "Edit" menu, select the "Know-how protection" command to open the "Change
protection" dialog.
3. To change the password for know-how protection, enter the current password under "Old
password".

"Confirm password".
5. Click "OK" to confirm your entry.
Result: The password for know-how protection of the selected block has been changed.
Removing block know-how protection
