Security Function (Copyprotect) - Siemens LOGO! Manual

6.1

Security function (CopyProtect)

The secuirty function provides copy protection for circuit programs on memory cards or
combined memory/battery cards.
Unprotected memory cards
You can edit circuit programs without restrictions and exchange data between the memory
card or combined memory/battery card and the device.
Protected memory cards
A circuit program is protected when it is transferred from a protected program memory card
or combined memory/battery 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 memory card or
combined memory/battery card.
Note
When you create the circuit program for a memory card or combined memory/battery card,
you need to assign a password (Page 76) to be able to edit it at a later time.
