10.7 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.
The link to the serial number means that you can only use the block in conjunction with the
corresponding 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. You can find additional information on setting
up know-how protection in the section Know-how protection (Page 230).
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".
