This applies to all sectors. That‘s why fast response times and
optimized processes form the basis for long-term competitiveness.
With Industrial Wireless LAN, the
SIMATIC Mobile Panel gives plant operators more freedom of movement. So it is always there where it is needed – without compromising safety.
PROFINET ensures maximum flexibility in plant structures and production processes, and it enables you to implement innovative machine and plant concepts. Mobile devices, for example, can be integrated into relatively inaccessible locations.
More flexibility with PROFINET.
Industrial Wireless LAN (IWLAN)
IWLAN reduces maintenance costs, increases reliability, and convinces with high communication
performance. Only PROFINET allows the combination of safety and IWLAN.
Safety-related communication via PROFIsafe reliably protects personnel, the environment, and plants.
PROFINET also enables the use of star, tree and ring topologies in addition to the linear topology.
Thanks to its openness, PROFINET creates the basis for a uniform machine/plant automation network to which programmable controllers as well as standard
Ethernet devices can be connected.
PROFINET is 100 percent Ethernet and supports
TCP/IP. Among other things, this enables the use of
Web technologies, such as access to the integrated
Web server of the field devices.
With PROFINET, network infrastructures can be
expanded as desired, even during operation.
The focus is on flexible topologies
PROFINET also enables the use of star, tree, and ring topologies in addition to the linear topology characterized by the established fieldbuses. This is made possible by switching technology via active network components, such as Industrial Ethernet switches and media converters, or by the integration of switch functionality into the field devices. This results in increased flexibility in machine and plant planning, as well as savings in cabling.
fiber-optic cables are used depending on the application. Devices from different manufacturers are easily connected via standardized and rugged plug connectors (up to IP65/IP67).
Thanks to the integration of switch functionality into the devices, linear topologies can be formed that are configured based on existing machine or plant structures. This results in savings in cabling overhead and cuts down on components such as external switches.
The PROFINET network can be installed without specialist knowledge and meets all requirements relevant to the industrial environment. The PROFINET
Guideline “Cabling and Interconnection Technology” supports manufacturers and users when installing networks. Symmetrical copper cables or RFI-resistant
different network topologies and thus enables a high degree of flexibility in machine and plant planning – even in combination with profiles such as PROFIsafe.
“With PROFINET, everything runs over one cable.
That‘s what I call real efficiency.”
More efficiency for your economic advantage.
Continually rising raw material prices and constantly new environmental regulations make it necessary for companies around the world to use their resources more cost-effectively and more efficiently. This applies above all to production. PROFINET ensures more efficiency here.
SIMATIC ET 200S supports the
PROFIenergy profile. This allows energy to be saved during breaks and increases plant efficiency.
Simple engineering guarantees fast commissioning, and reliable devices enable high plant availability. In addition, comprehensive diagnostics and maintenance concepts help to reduce plant downtimes and maintenance costs to a minimum.
More efficiency with PROFINET.
One cable for all purposes
PROFINET offers a host of functions on one cable:
Machine data and standard IT data run together.
This creates integration and saves costs by reducing the overhead for cabling and training.
Device and network diagnostics
Extensive diagnostic data can be read out from the devices to locate faults quickly. HTML standard
Web sites are used for servicing PROFINET devices – locally and remotely.
Increased energy efficiency
PROFIenergy switches off individual loads or entire production units during breaks – in a coordinated and centrally controlled way.
Fault-free establishment of industrial networks in a short time and without specialist knowledge:
PROFINET makes this possible with the FastConnect system.
Fast device replacement
When replacing a PROFINET device, the IO Controller detects the new device and automatically assigns its name.
High degree of ruggedness
The use of switches even in field devices prevents faults in one section of the network from influencing the entire plant network. PROFINET enables the use of fiber-optic cables especially for areas that are critically sensitive to EMI.
The focus is on device and network diagnostics
By retaining the field-proven PROFIBUS device model, the same diagnostic information is available with PROFINET. In addition, device diagnostics also includes readout of module-specific and channelspecific data from the devices. This enables simple and fast location of faults. As well as the availability of device information, the top priority in network management is reliability of network operation.
The Simple Network Management Protocol (SNMP) has become established in existing networks as the de-facto standard for the maintenance and monitoring of network components and their functions.
PROFINET uses this standard and provides users with the option of servicing networks using familiar tools such as the SINEMA Server network management software. In order to facilitate the maintenance of
PROFINET devices, both locally and also remotely via a secure VPN connection, application-specific Web sites in the familiar HTML standard can be created on the integral Web server of the field devices.
Data for energy efficiency
PROFINET enables parallel fieldbus communication and standard IT communication (TCP/IP).
This real-time communication for the transmission of user/process data and diagnostic data is performed on a single cable.
Profile commu nication
(such as PROFIsafe,
PROFIdrive, or PROFIenergy) can be integrated without additional cabling costs.
“High speed alone isn‘t everything.
PROFINET is not only fast, it can also simply do more.”
High performance for boosting your productivity.
Performance and precision determine market success. Precise motion control, dynamic drives, high-speed controllers, and the deterministic synchronization of devices are therefore key factors in achieving superior production.
SINAMICS drive technology and
PROFINET ensure the necessary speed in your machine and maximum precision in motion control applications.
PROFINET‘s performance power offers you more than enough reserves to meet today‘s requirements and those of the future, and thus makes it possible to continually increase your productivity.
More performance with PROFINET.
Fast motion control applications need high-speed data exchange. PROFINET’s short cycle times increase the productivity of machines and plants.
Communication via PROFINET is deterministic. A
jitter of <1 µs results in maximum precision cycles and thus guarantees high product quality.
Large quantity structures
With PROFINET, up to 256 devices can be managed by one SIMATIC controller. The number of nodes per network is practically unlimited.
High transmission rate
By using Ethernet, PROFINET achieves a significantly higher transmission rate than previous fieldbuses.
This enables problem-free transmission of even large volumes of data without affecting I/O data transfer.
Higher plant availability can be achieved by means of a redundant installation. This can be implemented both with the help of external switches and directly via integral PROFINET interfaces.
In modular plants, IO Controllers must detect new machines or plant sections quickly. With Fast
Start-up, PROFINET can detect devices in up to
<500 ms and connect them with the IO controller.
The focus is on speed and precision
Fast motion control applications need precise and deterministic data exchange. This is implemented thanks to isochronous drive controls using Isochronous Real Time (IRT). The different cycles of a system (input, network, CPU processing and output) are also synchronized in the case of parallel TCP/IP
PROFINET’s short cycle times make it possible to increase the productivity of machines and plants, and to ensure product quality through high precision of the cycle.
The standardized PROFIdrive profile enables vendorindependent communication between motion controllers and drives.
Warehousing and logistics
Acyclic data, diagnostic information
Standard IO, simple drive applications
High-speed IO, motion control
Real Time up to 250µs
Isochronous Real Time
10µs up to 31.25µs
PROFINET offers outstanding performance.
You can already im plement all your applications today with
PROFINET. With cycle times up to 31.25 µs, the PROFINET standard also offers you sufficient reserves for your future requirements.
experience also enabled me to set up the PROFINET solution without problems. In doing so, I dis covered the many benefits of
PROFIBUS or PROFINET?
PROFIBUS has been established for years as the fieldbus for machines and plants. Based on serial bus technology, it revolutionized the automation world in the 80s, and created for the first time the foundation for the distributed concepts common today. In the
90s, Ethernet spread into IT and industry. Today, manufacturing is inconceivable without both systems. But would it not be more efficient to combine the advantages of both systems?
The answer to this question is PROFINET. It merges the industrial experience of PROFIBUS with the openness and flexible options of Ethernet.
Bus cycle time
Network standard Ethernet
High transmission rate
Fieldbus standard PROFIBUS
High-speed IO communication
Significant performance gains can be achieved with PROFINET.
The advantages of
PROFIBUS, the leading fieldbus, combined with the diverse options of
Ethernet, form the basis of PROFINET. Highlights such as Safety over Wireless become as feasible as high-dynamic, isochronous motion control applications.
Good reasons for a change.
Can I continue to use my existing
PROFIBUS will continue to play an important role in the future. That’s why care was taken in the
development of PROFINET to enable simple and smooth integration of PROFIBUS. The engineering of
PROFINET is very similar to that of PROFIBUS. You can, for example, convert a SIMATIC ET 200S station to PROFINET simply by replacing an interface module: just change the configuration, reinstall, done.
of PROFINET to use. Test it out and configure a familiar and frequently used PROFIBUS application with PROFINET. You’ll be convinced by the simple handling and the results.
How will I benefit from the transition?
The many benefits that PROFINET offers in implementing automation tasks mean the transition is always worthwhile: Flexible topologies, one cable for all applications, wireless with safety, and significantly increased system performance thanks to scalable mechanisms speak for themselves.
Do I have to convert the entire plant at once, or can I make the transition in stages?
You can connect existing plant sections to PROFINET simply via the IE/PB Link PN IO or also wirelessly via the IWLAN/PB Link PN IO. The huge diversity of field devices on PROFIBUS can thus be integrated without problems into new PROFINET systems, and you can structure the transition individually and by stages.
Is the transition complicated?
You know the basic techniques: simple integration of distributed I/O such as PROFIBUS DP, assignment of addresses and names as with a PC. This facilitates the change and you can quickly put the advantages
When is the right time for me?
For many users, now is the best time for changing to PROFINET. The technology is mature and has been tried and tested in many customer applications. The wide range of available devices with PROFINET connection is being extended continuously, so devices are available for just about all application areas and sectors. You can thus use all of the functions with which PROFINET implements automation solutions more flexibly, more efficiently, and with higher performance.
PROFINET – this is my way.

Ethernet standards can also be utilized for your
application – no matter which sector you are in.
A comprehensive product portfolio
Siemens offers an extensive portfolio of PROFINETenabled products that is growing almost daily: many new Siemens automation products have PROFINET
PROFINET is a decision for the freedom to implement innovative machine and plant concepts that are perfectly tailored to your requirements. PROFINET stands for your individual success.
Flexibility: Lufthansa, Germany
Siemens provided a flexible solution based on PROFINET communication with around 50 stations for the modernization of a paint shop for Lufthansa in Hamburg, Germany. The innovative feature of this system is that safety-related information such as emergency stop is distributed in real time via a dynamic wireless network. This is made possible by the fail-safe PROFIsafe
V2 protocol. If employees on a platform press the emergency stop button, the signal is sent via the controller of the platform over IWLAN to the head-end station, and back to the relevant crane bridge, which is then switched off with the platform.
This requires an enormously high-speed controller. Thanks to the high availability of the controller, Lufthansa benefits from significantly reduced standstill times.
Efficiency: Iaco Agricola, Brazil
Iaco Agricola built a sugar factory and bio-ethanol plant in
Chapadao do Sul. The focus was on safe operation with as few downtimes as possible. The company decided on an efficient
Siemens automation solution with PROFINET communication.
A SIMATIC S7- 400 controller controls the processes. In the control room, the SIMATIC WinCC visualization system enables access to the system. The system can be accessed from any location in the plant via the WinCC WebNavigator. In this way,
PROFINET enables transparent, integrated and reliable communication, as well as fast, efficient system diagnostics. The downtime of the automation system is now only 0.28 percent.
Even under the extremely adverse conditions in the bio-ethanol industry, the system is extremely robust.
Performance: Herma, Germany
The coating plant of the label manufacturer Herma in
Filderstadt- Bonlanden, Germany, is the largest of its kind in the world. Due to its high production speed of 1100 m/min, it needed a communication solution that could keep pace with this level of performance. The challenge here for the drives technology was to find a solution for on-the-fly changing of material rolls at full machine speed. Use of the SIMOTION/
SINAMICS range enabled extremely accurate position control and precise timing when changing rolls. PROFINET with IRT
(Isochronous Real Time) ensured stable movement of the web thanks to distributed synchronous operation. Distributed implementation of safety functions such as emergency stop was also possible thanks to PROFIsafe.
