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 only form one element of such a concept.
Customer is responsible to prevent unauthorized access to its plants, systems, machines
and networks. Systems, machines and components should only be connected to the
enterprise network or the internet if and to the extent necessary and with appropriate security
measures (e.g. use of firewalls and network segmentation) in place.
Additionally, Siemens’ guidance on appropriate security measures should be taken into
account. For more information about industrial security, please visit
(http://www.siemens.com/industrialsecurity).
Siemens’ products and solutions undergo continuous development to make them more
secure. Siemens strongly recommends to apply product updates as soon as available and to
always use the latest product versions. Use of product versions that are no longer supported,
and failure to apply latest updates may increase customer’s exposure to cyber threats.
To stay informed about product updates, subscribe to the Siemens Industrial Security RSS
Feed under (http://www.siemens.com/industrialsecurity).

2.1 Applications of the S7-1500 CPUs
Technology modules also implement functions such as high-speed counting, position
detection, measuring functions and pulse generators (PTO, PWM and frequency output). For
compact CPU 1511C-1 PN and CPU 1512C-1 PN CPUs, these functions are already
integrated and can be implemented without additional technology modules.
SIWAREX is a versatile and flexible weighing module which you can use as a static scale for
operation.
In conjunction with STEP 7 (TIA Portal), each CPU offers password-based know-how
protection against unauthorized reading out or modification of the program blocks.
The copy protection provides reliable protection against unauthorized reproduction of
program blocks. With copy protection, individual blocks on the SIMATIC memory card are
linked to its serial number so that the block can only be executed if the configured memory
card is inserted in the CPU.
In addition, four different authorization levels in the CPUs can be used to assign different
access rights to various user groups.
Improved manipulation protection allows the CPUs to detect changed or unauthorized
transfers of the engineering data.
The use of an Ethernet CP (CP 1543-1) provides the user with additional access protection
by means of a firewall and/or the option of secured VPN connections.
The fail-safe CPUs are intended for users who want to implement demanding standard and
fail-safe applications both centrally and distributed.
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 13849-1:2006 or according to
EN ISO 13849-1:2008
Additional password protection for F-configuration and F-program is set up for IT security.

System diagnostics and messages
2.1 Applications of the S7-1500 CPUs
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 immediately shown on the display in plain text. In the case of servicing, plant
downtimes are minimized by quick access to diagnostics alarms. Detailed information about
this and a multitude of other display functions is available in the SIMATIC S7-1500 Display
Simulator (http://www.automation.siemens.com/salesmaterial-as/interactive-manuals/getting-
started_simatic-s7-1500/disp_tool/start_en.html).
Uniform front connectors for all modules and integrated potential jumpers for flexible
formation of potential groups simplifies 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 S7-1500. The CPUs of the SIMATIC S7-1500 product series can be expanded
centrally and modularly 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 the easy wiring inside the control cabinet
(flexible connection consisting of front connectors with assembled single conductors).
Integrated system diagnostics is enabled by default for the CPUs. The different types of
diagnostics are configured instead of programmed. System diagnostics information is shown
uniformly and in plain text on the display of the CPU, in STEP 7 (TIA Portal), on the HMI and
on the Web server, even for alarms related to drives. This information is available in RUN
mode, but also in STOP mode of the CPU. The diagnostics 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 specified for the CPU. If you require message
texts in additional languages, you can load these via the configured connection to your HMI.
The CPU, STEP 7 and your HMI guarantee data consistency without additional engineering
steps. The maintenance work is easier.

MRP (Media Redundancy
Protocol)
MRPD (Media Redundancy with Planned Duplication)
A reserved bandwidth within the send clock is available
for IRT data. The reserved bandwidth ensures that the
IRT data can be transmitted in time-synchronized intervals, unaffected by other high network loading (e.g.
TCP/IP communication or additional real time communication). Update times with maximum determinism can
be realized through IRT. Isochronous applications are

signals in a fixed system clock. Isochronous mode thus
contributes to high control quality and hence to greater
manufacturing precision. Isochronous mode reduces
possible fluctuations of the process reaction times to a
minimum. Time-assured processing makes higher
It is possible to establish redundant networks via the
Media Redundancy Protocol. Redundant transmission
links (ring topology) ensure that an alternative communication path is made available if a transmission link
fails. The PROFINET devices that are part of this redundant network form an MRP domain.
RT operation is possible with the use of MRP.
The advantage of the MRP extension MRPD is that, in
the event of a failure of a device or a line in the ring, all
other devices continue to be supplied with IO data
without interruption and with short update times.
MRPD is based on IRT and MRP. To realize media
redundancy with short update times, the PROFINET
devices participating in the ring send their data in both
directions. The devices receive this data at both ring

Without the "Shared device" function, each I/O module
of an IO device is assigned to the same IO controller. If
sensors that are physically close to each other must
provide data to different IO controllers, several IO devices are required. The "Shared device" function allows
the modules or submodules of an IO device to be divided up among different IO controllers, thus allowing
