9.5 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 linking of the serial number of a SIMATIC memory card or of a CPU the use of
this program or of this block is only possible in conjunction with a specific SIMATIC memory
card or CPU.
Copy and know-how protection
Recommendation: to prevent unauthorized reset of copy protection, additionally apply
know-how protection to a copy-protected block. To do this, first set up copy protection and
then apply know-how protection for the block. You can find further information on setting up
know-how protection in section Know-how protection (Page 160)
Setting up copy protection
To set up copy protection, follow these steps:
1. Open the properties of the block in question.
2. Select the "Protection" option under "General".
