Answers for industry.
PROFINET –
The Open Ethernet Standard
PROFINET is the Ethernet standard for automation,
enabling high-speed, secure data exchange between
field devices from different manufacturers. Therefore, PROFINET makes it possible to create inno­va­
tive machine and system designs. The standard is
supported by PROFIBUS & PROFINET International (PI),
the world‘s largest fieldbus organization. A global
network of 28 PROFINET competence centers is
available to support you with all PROFINET related
questions.
PROFINET for field devices
PROFINET provides manufacturers of field devices
with new ways of making their products more attractive to end users through innovative functions.
Integrated diagnostics and alarm functions ensure
fast commissioning times and optimized machine
maintenance. Besides diagnostics without engineering tools, direct access via TCP/IP also makes it
­possible to transfer large amounts of data such as
quality assurance or traceability information parallel
to IO communication. Besides these value-added
services, PROFINET‘s centerpiece of IO data transfer
also does not miss out.
2
Absolute deterministic behavior is ensured through
prioritization of the Ethernet message frames. The
use of Isochronous Real Time (IRT) with cycle times
up to 31.25 µs also makes high-performance applications such as Motion Control possible.
The PROFINET IO device model follows the same
principle as the PROFIBUS DP device model. This
makes it quick and simple for the field d
­ evice
­developer to complete the logical step from
­PROFIBUS to PROFINET. Also the principle of the
­device description has been retained as a GSD file
and simplified through an XML-based variant.
Engineering or diagnostics data is generally transferred via TCP/IP. An Ethernet-capable device can be
integrated into a PROFINET network at any time via a
free port. A field device can be accessed on the web
server both locally and via remote diagnostics via a
secure router using a standard Internet browser. The
same mechanism is thereby effective from remote
maintenance to the field device: i.e. standard
Ethernet.

Application of standards
PROFINET relies on established standards from the
IT world in many areas. For example, the protocols
LLDP and SNMP are used for the topological neighbor relationships. Non-time-critical data such as
diagnostics records are transmitted via UDP/IP. In
this way, web servers or other established services
from the world of IT can be implemented without
restriction on PROFINET devices. This openness of
PROFINET introduces new possibilities for both field
device manufacturers and end users.

PROFINET Implementation
in Field Devices
PROFINET is 100% standard Ethernet and at the
same time offers appropriate mechanisms for very
high real-time requirements.
■■PROFINET with real time (RT) can be used for
process data transfer with a cycle time of up to
1 ms. Implementation can be realized on a
standard Ethernet controller.
■■Siemens offers special ASICs which support
PROFINET with isochronous real time (IRT) for the
synchronous transfer of process data with a cycle
rate of <1 ms and a jitter accuracy of 1 μs.
The ERTEC ASIC is the perfect choice for a field device which is to support cycle times of <1 ms. If cycle
times of 1 ms and more are sufficient, PROFINET
integration can also be realized on the basis of standard Ethernet controllers. This facilitates easy and
cost-efficient implementation thanks to the usability
of existing hardware.
PROFINET is based on switched Ethernet technology. This means that the communication between
two field devices is always point-to-point connections, even if the field devices are connected in line.
Thanks to standard Ethernet technology, PROFINET
therefore guarantees the building of any desired
topologies. In this way, in addition to line and ring
topology, a star and tree topology is also possible,
along with all mixed forms. The bandwidth in
individual topology branches is divided, since data
through direct point-to-point communication does
not need to pass through each individual network
participant.
The application options to be offered to customers
are decisive for field device manufacturers. Devices
with a 1-port solution can only be integrated in
star and tree topologies. In contrast, devices with a
2-port switch solution can also be used in line and
ring structures.

Performance Upgrade
for PROFINET
With IRT, the PROFINET performance
upgrade facilitates attainable cycle times
of 31.25 µs. This is supported by the fast
forwarding, dynamic frame packing and
fragmentation mechanisms.

short video animation:
Integration of additional features
PROFINET enables additional functionalities to be
integrated based on a standard Ethernet controller.
Thanks to PROFINET development kits from Siemens,
some of these features are already integrated in the
PROFINET stack:
Media Redundancy Protocol (MRP)
Higher system availability can be achieved with a
redundant installation through ring topology. Short
reconfiguration times of 200 ms prevent any system
standstill. Any required maintenance and repair
work can be carried out with no time pressure.
Shared Device
Several controllers can use the same PROFINET device with this functionality. This results in easy and
economical system configuration, for example for
applications in which the standard CPU runs separately from the fail-safe CPU.
PROFIenergy
With this manufacturer and device-independent profile defined by PROFIBUS & PROFINET International
(PI), any unnecessary devices can be purposefully
switched off during rest periods. This is coordinated
centrally through a higher-level controller. Field
devices have an integrated switch-off function.
Field device manufacturers can, in addition, integrate further manufacturer-independent profiles
specified by PI:
PROFIsafe
PROFIsafe is the world‘s leading universal technology (IEC 61508 compliant) for functional safety
in manufacturing and process automation. The
PROFIsafe profile is tried and tested in many applications and has since become an international
standard according to IEC 61784-3-3.
PROFIdrive
PROFIdrive is an interface between the control and
the drive (IEC 61800-7) and it defines the device and
access procedure to internal drive data for electrical
drives – from the simple frequency converter to the
high-performance servo regulator.
PROFINET offers the field device manufacturer many
additional options including the integration of a web
server for access to diagnostics data with a standard
Internet browser.

ERTEC products
ERTEC ASICs
The ASICs of the ERTEC range represent Ethernet
controllers on the basis of ARM 9 processors with integrated IRT switch. They elegantly meet all capability requirements in terms of real time, line topology
and IT integration.
Cyclic data transfer for PROFINET on the basis of
real time and isochronous real time is completely
carried out via the integrated switch. As a result,
sufficient processor resources are available for the
processing of simple field device applications in the
ARM processor.
Various development packages are available for the
development of field devices with ERTEC ASICs. Easy
getting started is supported by simple application
examples.
ERTEC 200P – High-Speed with PROFINET
The ERTEC 200P sets new standards with regard
to the communication performance of PROFINET.
Dimensioned for cycle times of up to 31.25 µs,
the performance upgrade for PROFINET was for the

PROFINET test laboratory
Field devices are networked together in machines
and systems via fieldbuses such as PROFINET.
Using certified field devices thereby guarantees
the interoperability of components from different
manufacturers and thus contributes to higher
system availability and to time and cost savings
for the operator.
The certification tests include:
■■Hardware tests
■■Load tests
■■State machine tests
■■Reaction to faults
■■Alarm tests
■■Check of the GSD file
For this reason, device certification for PROFINET
via an accredited test laboratory is mandatory. The
PI-accredited test laboratories of ComDeC, PIC and
ANF Data have now successfully completed over 800
certification tests. This ensures that devices in the
field always meet the requirements of the industrial
environment. ComDeC, PIC and ANF Data are also
the global leaders for the PROFINET certification
tests already carried out.
All tests are carried out in practice-oriented and
established automation systems, with the latest edition of the SIMATIC S7 programmable logic controllers from Siemens. External technical experts may be
physically present for the certification tests at any
time, thereby rectifying certain faults quickly and
easily. Third-party know-how is always protected:
the test laboratories are under an obligation to keep
all customer information confidential.
Certification sequence
Certification is extremely simple for PROFINET field
device manufacturers: the finished PROFINET device
is checked by one of the accredited test laboratories.
