Security Function (Copyprotect); Unprotected Program Module (Card); Protected Program Module (Card) - Siemens Logo! Manual

6.1 Security function (CopyProtect)

We principally distinguish between program modules (card)
with and without circuit program/copy protection.

Unprotected program module (card)

You can edit circuit programs without restrictions, and ex-
change data between the program module (Card) and the
device.

Protected program module (card)

A circuit program is protected when it is transferred from a
protected program module (card) to the LOGO!.
To execute this circuit program in LOGO!, the protected
program module (card) must remain inserted during RUN,
i.e. the circuit program stored on the program module
(card) can not be copied to other LOGO! devices.
Over and above that, a protected circuit program is write–
protected.
A circuit program with password protection is no longer
protected after the correct password has been entered, i.e.
you can then edit the program and remove the module.
Note
You need to assign a password when you create the circuit
program for a protected module (card) to be able to edit it
at a later time (see Chapter 3.7.5).
