8.1 Security function (CopyProtect)

8.1Security 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.
