Security Function (Copyprotect) - Siemens LOGO! Series Manual

8.1

Security function (CopyProtect)

The security function provides copy protection for circuit programs on memory cards,
combined memory/battery cards or SD cards.
Unprotected cards
You can edit circuit programs without restrictions and exchange data between the card and
the device.
Protected cards
A circuit program is protected when it is transferred from a protected program card to
LOGO!.
To execute this circuit program in LOGO!, the protected card must remain inserted during
RUN; that is, the circuit program stored on the card cannot be copied to other LOGO!
devices.
In addition, a protected circuit program is write-protected.
A circuit program with password protection is no longer protected after the correct password
has been entered; that is, you can then edit the program and remove the card.
Note
When you create the circuit program for a card, you need to assign a password (Page 91) to
be able to edit it at a later time.
