Integrity protection of the SIMATIC Memory Card, CPU FW Version V3.1 or higher
For CPUs as of FW version V3.1, the integrity protection of the SIMATIC Memory Card
depends on the password for the protection of confidential configuration data that you
assigned when configuring the CPU. This results in the following changes in the handling of
SIMATIC Memory Cards:
• Drag-and-drop a CPU to a card reader/USB memory:
For CPUs as of FW version V3.1, you must enter the password of the CPU with which you
want to use the SIMATIC Memory Card. If you enter an incorrect password, the CPU will
not start startup when switched on and will report the contents of the SIMATIC memory
card as faulty.
• Insert a CPU from a card reader/USB memory:
In order to be able to check the integrity of the contained configuration in STEP 7, you
must enter the password of the CPU from which the configuration was loaded. In this
case, STEP 7 checks the data on the SIMATIC Memory Card and reports possible damage.
Entering the password is optional. If you do not want to use the integrity check, you do
not need to enter the password (restore project).
Access protection example
You can choose from four different access levels in the TIA Portal to restrict user access to
functions and memory areas.
Figure 5-9
If you only want to allow users access over HMI, for example, select the access level "HMI
access" in the TIA Portal. Only HMI access and access to diagnostics data is then possible
without entering a password.
Users can read and write tags over an HMI device with this access level.

Description
Improved management of users, roles, and CPU function rights (User Management & Access
Control, UMAC). You can use the local user management to manage all project users with
their rights (for example, access rights) in the editor for users and roles of the project in the
TIA Portal.
Protection against unauthorized configuration changes using authorization levels
Protection against unauthorized access by locking the bottom cover with a seal or a lock
