Safety instructions 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.
To stay informed about product updates, subscribe to the Siemens Industrial Security RSS
Feed visit (https://www.siemens.com/cert).

3.1 New functions
This section contains an overview of the most important new firmware functions of the CPU
compared to the predecessor CPU (V2.9).
New functions of the CPU in firmware version V3.0
New functions Applications Customer benefits
Communication of the CPU
SNMP network manage
ment protocol
A simple configuration option is available for
using SNMP services. For new configurations,
this is disabled by default in line with "Security-
by-Default".
Can be enabled/disabled in the CPU properties.
Community strings are configurable.
OPC UA server – Reading
the diagnostic status of
the own address space
By using the OPC UA instruction for reading
("OPC_UA_ReadList"), the own namespace of
the OPC UA Server can be accessed.
This allows you to read out the following
statuses and react to them in the user program:
• Status of the own OPC UA server
• Status of the connections of OPCUA clients
• Status of the session
• Status of subscriptions
In this way, connection problems can be quickly
detected, for example, and the plant availability
can be increased.
OPC UA server – Time
stamping of the source
time of nodes
By using the OPC UA instruction for writing
("OPC_UA_WriteList"), it is possible to change
the "SourceTimestamp" as well as the status
code of an OPC UA variable (node).

The following configuration limits have been
increased:
• Possible number of nodes in the server
interface
• Maximum possible number of subscriptions

that are determined cyclically by the application
for additional distance, velocity and accelera
tion and are additive to the basic motion.
By specifying superimposed motion setpoints, you
can optimize the motion profile of a basic motion.

These CPUs are described in the fail-safe CPUs.
Performance segments of fail-safe CPUs
The fail-safe CPUs are intended for users who want to implement demanding standard and
fail-safe applications both centrally and decentrally.
These fail-safe CPUs allow the processing of standard and safety programs on a single CPU.
This allows fail-safe data to be evaluated in the standard user program. The integration also
provides the system advantages and the extensive functionality of SIMATIC for fail-safe
applications.
The fail-safe CPUs are certified for use in safety mode up to:
•Safety class (Safety Integrity Level) SIL 3 according to IEC61508:2010
•Performance Level (PL) e and Category 4 according to ISO 13849-1:2015 or EN ISO

In addition to the CPUs, further components such as SINAMICS drives dispose of integrated
safety functions. Additional information about integrated safety functions in drives can be
found in the manuals for the respective products.
Security Integrated
In conjunction with STEP7, each CPU offers password-based know-how protection against
unauthorized reading out or modification of the program blocks.
Copy protection provides reliable protection against unauthorized reproduction of program
blocks. With copy protection, individual blocks on the SIMATIC memory card can be tied to its
serial number so that the block can only be run if the configured memory card is inserted into
the CPU.
In addition, various access rights can be assigned in the controller to different user groups
using four different authorization levels.
Improved manipulation protection allows changed or unauthorized transfers of engineering
data to be detected by the controller.
The use of an Ethernet CP (CP 1543-1) provides you with additional access protection
through a firewall or possibilities to establish secure VPN connections.
Design and handling
All CPUs of the SIMATIC S7-1500 product series feature a display with plain text information.
The display provides the user with information on the order numbers, firmware version, and
serial number of all connected modules. In addition, the IP address of the CPU and other
network settings can be adapted locally without a programming device. Error messages are
shown on the display directly in plain text. When performing servicing, you can minimize
plant downtimes by quickly accessing the diagnostics alarms. Detailed information about this
and a multitude of other display functions is available in the SIMATICS7-1500 Display Simu
lator (https://support.industry.siemens.com/cs/ww/en/view/109761758).
Uniform front connectors for all modules and integrated potential jumpers for flexible
formation of potential groups simplify storage. Additional components such as circuit
breakers, relays, etc., can be installed quickly and easily, since a DIN rail is implemented in the
rail of the SIMATIC S7-1500. The CPUs of the SIMATIC S7-1500 product series can be
expanded centrally and in a modular fashion with signal modules. Space-saving expansion
enables flexible adaptation to each application.
The system cabling for digital signal modules enables fast and clear connection to sensors
and actuators from the field (fully modular connection consisting of front connector modules,

connection cables and I/O modules), as well as easy wiring inside the control cabinet (flexible
connection consisting of front connectors with assembled single conductors).
System diagnostics and alarms
Integrated system diagnostics is activated by default for the CPUs. The different types of
diagnostics are configured instead of programmed. System diagnostics information and
alarms from the drives are displayed consistently and in plain text:
•On the CPU display
•In STEP7
•On the HMI
•On the Web server
This information is available in RUN mode, but also in STOP mode of the CPU. The diagnostic
information is updated automatically when you configure new hardware components.
The CPU is available as a central interrupt server in up to three project languages. The HMI
takes over the display in the project languages defined for the CPU. If you require alarm texts
in additional languages, you can load them into your HMI via the configured connection. The
CPU, STEP7 and their HMI ensure data consistency without additional engineering steps. The
maintenance work is easier.
