Copy protection
Application
The copy protection allows you to protect your program against unauthorized duplication.
With copy protection you associate the blocks with a specific SIMATIC memory card or CPU.
Through the association with the serial number of a SIMATIC memory card or CPU, the use
of this program or block is only possible in combination with a specific SIMATIC memory
card or CPU.
Copy and know-how protection
Recommendation: To prevent an unauthorized reset of the copy protection, provide a copy-
protected block with additional know-how protection. First set up the copy protection for the
block and after this the know-how protection.
Setting up copy protection
To set up copy protection, follow these steps:
1.
Open the properties of the respective block.
2.
Select the "Protection" option under "General".
3.
In the "Copy protection" area, select either the "Bind to serial number of the CPU" entry or
the "Bind to serial number of the memory card" entry from the drop-down list.

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 will be rejected. This means that blocks
without copy protection will also not be downloaded.
