Security information 2
2.1 Security information
Siemens provides products and solutions with industrial security functions that support the
secure operation of plants, systems, machines and networks.
In order to protect plants, systems, machines and networks against cyber threats, it is
necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial
security concept. Siemens’ products and solutions constitute one element of such a concept.
Customers are responsible for preventing unauthorized access to their plants, systems,
machines and networks. Such systems, machines and components should only be connected
to an enterprise network or the internet if and to the extent such a connection is necessary
and only when appropriate security measures (e.g. firewalls and/or network segmentation)
are in place.
For additional information on industrial security measures that may be implemented, please
visit (https://www.siemens.com/industrialsecurity).
Siemens' products and solutions undergo continuous development to make them more
secure. Siemens strongly recommends that product updates are applied as soon as they are
available and that the latest product versions are used. Use of product versions that are no
longer supported, and failure to apply the latest updates may increase customers' exposure to
cyber threats.

Technology Module TM NPU
Equipment Manual, 07/2023, A5E46384784-AC

2.2 Module-specific security information
Observe the following security instructions. In this way, you protect the TMNPU against
unauthorized access.
In addition, you prevent:
•Loss of data
or
•Manipulation
or
•Limited availability of the module
Use of the Ethernet interface
The TMNPU Ethernet interface and the services contained therein are exclusively designed
for communication in an access-protected area of your system.
Connecting the TMNPU Ethernet to a cloud or a device outside of this access-protected area
is a security risk. Establish the communication with external cloud services or devices via a
secure interface, e.g. IndustrialEdge.
Note that all FTP, GigE Vision (Page 21) and web server communication is unencrypted.
The following table shows the services, their port numbers and the respective default states:
Service Port no. Default state
FTP client Dynamic Disabled
GigE Vision 49152 Disabled
Web server 80 Disabled
When designing the network to which the TMNPU is connected, take the following criteria
into account:
•Avoidance of excessive network load
–A network overload is diagnosed in the value status (status byte, bit 0).
You can find more information in section: Status and error information in the process
image input (PII) (Page 28).
–The module might stop functioning. In this case, restart the module.
•Prevention of unauthorized access
Locking the housing
To protect the data on the SIMATIC Memory Card from unauthorized access, lock the housing
using a lock on the front cover (Page 55).
Ports disabled by default: USB and Ethernet
To prevent a third-party device from damaging your system, the USB and Ethernet interfaces
are disabled by default.
To activate the interfaces and related services, use these options:
•Parameter settings in HW Config (Page 26)
8Technology Module TM NPU
Equipment Manual, 07/2023, A5E46384784-AC
Security information
2.2 Module-specific security information

Locking the Ethernet port
Lock the unused Ethernet port mechanically with an RJ 45port lock.
Diagnostic message when the SIMATIC Memory Card is removed
Removing the SIMATIC Memory Card during operation triggers a diagnostic event, which is
indicated in the value status (error byte, bit 1) in the PII.
You can find more information in section: Status and error information in the process image
input (PII) (Page 28)
Preventing loss of data on the SIMATIC Memory Card
Routinely create backup copies of the contents of the SIMATIC Memory Card, e.g. neural
networks, apps/scripts and configuration files.
In this way, you protect your know-how from tampering or stolen SIMATIC Memory Cards.
Disabling debug mode via web server during operation
If the module has been enabled for commissioning, then ensure that debug mode via web
server has been disabled during module operation. This prevents unauthorized access and
thus the reading of potentially confidential diagnostic information (MicroPython debug
information).
You disable the web server through configuration in HW Config. Default state of the web
server: disabled.
To prevent it from being enabled (again) without permission, also delete the configuration
filedebug.conf (Page 59) from the SIMATIC Memory Card after commissioning.
2.3 Important information regarding decommissioning of the
module
When you decommission the TMNPU, remove the SIMATIC Memory Card. In this way, you
prevent improper access to your data.
