ation to which particular attention
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 (http://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.

Other technology functions
Technology modules also implement functions such as high-speed counting, position
detection and 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, 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, you can assign various access rights to different user groups in the controller
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 the user with additional access protection
through a firewall or possibilities to establish secure VPN connections.
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
thereby 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.
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.

CPU 1517T-3 PN/DP (6ES7517-3TP00-0AB0)
18 Manual, 12/2017, A5E36285525-AB
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 bridges 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 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 is shown
uniformly and in plain text on the display of the CPU, in STEP 7, 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 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 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.

Firmware functions
Functions
The CPU 1517T-3 PN/DP supports the following functions:
Integrated system
diagnostics
The system automatically generates the messages for
the system diagnostics and outputs these messages
via a programming device/PC, HMI device, the Web
server or the integrated display. System diagnostics
information is also available when the CPU is in STOP
Diagnostics function manual
(http://support.automation.siemens.c
om/WW/view/en/59191792)
The Web server lets you access the CPU data by
means of a network. Evaluations, diagnostics, and
modifications are thus possible over long distances.
Monitoring and evaluation is possible without STEP 7;
all you need is a Web browser. Make sure that you take
appropriate measures (e.g. limiting network access,
using firewalls) to protect the CPU from being compromised.

Integrated trace
functionality
Trace functionality supports you in troubleshooting
and/or optimizing the user program.
You record device tags and evaluate the recordings
with the trace and logic analyzer function. Tags are, for
example, drive parameters or system and user tags of
a CPU.
The device saves the recordings. You can read out and
permanently save the recordings with the configuration
system (ES), if required. The trace and logic analyzer
function is therefore suitable for monitoring highly
dynamic processes.
The trace record can also be displayed through the

om/WW/view/en/64897128)
With OPC UA, you can exchange data via an open and
manufacturer-neutral communication protocol. The
CPU can act as an OPC UA DA server. The CPU acting as the OPC UA server can communicate with
OPC UA clients.
The OPC UA Companion Specification allows methods
to be specified uniformly and independently of the
manufacturer. Using these specified methods, you can
easily integrate devices from various manufacturers
into your plants and production processes.
Communication function manual
(https://support.industry.siemens.co
m/cs/ww/en/view/59192925)
You can use configuration control to operate different
real hardware configurations with a configured maximum configuration of the hardware. This means that, in
series machine manufacturing in particular, you have
the option of operating/configuring different configura-
tion variants of a machine with a single project.

22 Manual, 12/2017, A5E36285525-AB
RT (real time) RT prioritizes PROFINET IO telegrams over standard
telegrams. This ensures the required determinism in
the automation technology. In this process the data is
transferred via prioritized Ethernet telegrams.
PROFINET function manual
(http://support.automation.siemens.c
om/WW/view/en/49948856)
IRT
(isochronous real time)
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 possible with IRT.
Isochronous mode The Isochronous mode system property acquires
measured values and process data and processes the
signal 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
MRP (Media Redundancy
Protocol)
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.
MRPD
(Media Redundancy with
Planned Duplication)
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
ports so that there is no reconfiguration time.
Shared device The "Shared device" function allows you to divide the
modules or submodules of an IO device up among
different IO controllers. Numerous IO controllers are
often used in larger or widely distributed systems.
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
flexible automation concepts. You can, for example,
combine I/O modules that are physically close to each

PROFIenergy PROFIenergy is a PROFINET-based data interface for
switching off consumers centrally and with full coordination during pause times regardless of the manufacturer or device type. Through this, the process should
only be provided with the energy that is absolutely
required. The majority of the energy is saved by the
process; the PROFINET device itself only contributes a
few watts of savings potential.
Motion Control S7-1500 CPUs support the controlled positioning and
traveling of axes via S7-1500 Motion Control functions
by means of the following technology objects:
Speed-controlled axes, positioning axes, synchronized
axes, external encoders, cams, cam tracks and
measuring inputs.
• Speed-controlled axis for controlling a drive with
speed specification
• Positioning axis for position-controlled positioning of
a drive
• Synchronous axis to interconnect with a master
value. The axis is synchronized to the master axis
position.
• External encoder for detecting the actual position of
an encoder and its use as a master value for
synchronous operation
• Cams, cam track for position-dependent generation
of switching signals
• Measuring input for fast, accurate and event-
dependent sensing of actual positions
You program the technology objects with Motion
Control instructions according to PLCopen.

Copy protection Copy protection links user blocks to the serial number
of the SIMATIC memory card or to the serial number of
the CPU. User programs cannot run without the corre-
sponding SIMATIC memory card or CPU.
Access protection Extended access protection provides high-quality
protection against unauthorized configuration changes.
You can use authorization levels to assign separate
rights to different user groups.
Integrity protection The CPUs dispose of integrity protection by default.
Integrity protection identifies possible manipulations of
engineering data on the SIMATIC memory card or
during data transfer between TIA Portal and CPU.
Integrity protection also checks the communication
from a SIMATIC HMI system to the CPU for possible
manipulations of engineering data.
If integrity protection identifies the manipulation of
engineering data, the user receives a corresponding
Password provider As an alternative to manual password input you can
connect a password provider to STEP 7. A password
provider offers the following advantages:
• Convenient handling of passwords. STEP 7 reads
the password automatically for the blocks. This
saves you time.
• Optimum block protection because the users do not
know the password itself.

Supply of I/O devices
CPU
1517T-3 PN/DP does not provide a 24 V
DC power supply on the PROFIBUS interface.
I/O devices (for example, PC adapter USB) are therefore only operational on the interface in
conj
unction with a plug-in power supply set for external power supply.
The innovative successor product, PC adapter USB
A2, receives the required power supply
via the USB port. The USB
A2 PC adapter therefore does not require a 24 V DC supply
a plug-in power supply set for external power supply.
