Copy protection
Application
The copy protection allows you to protect your program against unauthorized duplication.
Copy protection allows you to link the program or the blocks to 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".
