4. Activate the option "Serial number is inserted when downloading to a device or a memory
card" if STEP 7 is to automatically insert the serial number during the uploading process
(dynamic binding). Assign a password using the "Define password" button to link the use of
a block additionally to the input of a password.
If you want to manually bind the serial number of the CPU or the SIMATIC memory card to a
block (static binding), activate the "Enter serial number" option.
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.
Removing copy protection
To remove copy protection, follow these steps:
1. Remove the Know-how protection (Page 230), if it is set.
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.
