4. If STEP 7 is to automatically insert the serial number during loading (dynamic binding),
then activate the option "Serial number is inserted when downloading to a device or a
memory card". To link the use of a block/program additionally to the input of a password,
assign a password using the "Define password" button.
If you want to manually bind the serial number of the CPU or the SIMATIC memory card
to a block (static binding), select the option "Enter serial number".
5. You can now set up the know-how protection for the block in the "Know-how protection"
area.
Note
If you download a copy-protected block to a device that does not match the specified
serial number, the entire download operation is not possible. This means that you also
cannot download blocks without copy protection.

1. Remove any existing Know-how protection (Page 64).
2. Open the properties of the respective block.
3. Select the "Protection" option under "General".
4. In the "Copy protection" area, select the "No binding" entry from the drop-down list.
