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).

3.3 Firmware functions
Functions
The CPU supports the following functions:
Function Description Additional information
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 mode.
Diagnostics function manual
(https://support.automation.siemens.
com/WW/view/en/59192926)
Integrated web server 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, only a web
browser is required. Note that you must take appropriate
measures to protect the CPU from compromise (such as
restricting network access, using firewalls).

lers system manual
(https://support.industry.siemens.
com/cs/ww/en/view/90885010)
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 web
server.
With the project trace, you record the variables of mul
tiple devices within a project, for example, a controller
and a drive.
With the long-term trace, you record up to 64 different
tags for each cycle in a .csv file over a long period (e.g.
hours, days).

Function Description Additional information
OPC UA With OPCUA, you can exchange data via an open and
manufacturer-neutral communication protocol.
The CPU can act as OPC UA server. The CPU acting as the
OPCUA server can communicate with OPCUA clients.
In turn, as an OPC UA client, the CPU can access an OPC
UA server, allow the OPC UA server to run methods and
read out information from the OPC UA server.
Through OPC UA Companion Specification, methods can
be specified in a uniform and vendor-neutral way. Using
these specified methods, you can easily integrate devices
from various manufacturers into your plants and produc
tion processes.
Communication function manual
(https://support.industry.siemens.
com/cs/ww/en/view/59192925)
Configuration control You can use configuration control to operate different
real hardware configurations with a configured maxim
um configuration of the hardware. This means especially
in series machine manufacturing you have the option of
operating/configuring different configuration variants of
a machine with a single project.
ET200SP System Manual

com/cs/ww/en/view/58649293)
PROFINETIO
RT (real time) RT prioritizes PROFINET IO telegrams over standard tele
grams. This ensures the required determinism in the
automation technology. In this process the data is trans
ferred via prioritized Ethernet telegrams.
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 real
ized through IRT. Isochronous applications are possible
with IRT.
Isochronous mode The Isochronous mode system property acquires meas
ured values and process data and processes the signals in
a fixed system clock. Isochronous mode thus contributes
to high control quality and hence to greater manufactur
ing precision. Isochronous mode reduces possible fluctu
ations of the process reaction times to a minimum. Time-
assured processing makes higher machine cycles pos
sible.
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 commu
nication path is made available if a transmission link fails.
The PROFINET devices that are part of this redundant net
work 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 redund
ancy with short update times, the PROFINET devices par
ticipating in the ring send their data in both directions.

Product overview
3.3 Firmware functions

Function Description Additional information
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 differ
ent 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 mod
ules 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 other in one IO
device.
PROFIenergy PROFIenergy is a PROFINET-based data interface for
switching off consumers centrally and with full coordina
tion during pause times regardless of the manufacturer
or device type. The goal is that the process is only
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.

synchronized axes, external encoders, cams, cam tracks
and measuring probes.
• Speed-controlled axis for controlling a drive with

Integrated safety
Know-how protection The know-how protection protects user blocks against
unauthorized access and modifications.
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 correspond
ing SIMATIC memory card or CPU.
Access protection Extended access protection provides high-quality protec
tion against unauthorized configuration changes. You
can use authorization levels to assign separate rights to
different user groups.
Integrity protection The CPUs feature an integrity protection function by
default. This helps to detect any manipulation of the
engineering data on the SIMATIC Memory Card or during
data transfer between the TIA Portal and the CPU, and to
check communication from a SIMATIC HMI system to the
CPU for possible manipulation of engineering data. The
user receives a corresponding message about manipula
tion of engineering data detected by the integrity protec
tion.
Password provider As an alternative to manual password input you can con
nect 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.
