Advantage with PROFINET

Productivity to the power of four – for all professionals

PROFINET gives you new ways to boost your productivity with four key advantages – openness, flexibility, efficiency, and performance.

Two powerful standards, one common network

With PROFINET you’re best prepared for the digital transformation and the world of Industrie 4.0. Regardless of whether you intend to integrate new communication standards like OPC UA, combine IT and production networks, or take the next major step with Time-Sensitive Networking (TSN) – the turbo power for PROFINET and OPC UA.

Intelligent networking for the digital factory

OPC UA, the open, Ethernet-based communication standard, is the perfect enhancement to PROFINET. The way both standards work together smoothes the path to seamless communication in the world of automation and IT, and perfectly combines the advantages of both in a single industrial Ethernet network.


PROFINET scores at the field level with deterministics, a large bandwidth for increasing numbers of signals, and strict real-time capability for faster and faster applications. The strengths of OPC UA, on the other hand, lie mainly in machine-to-machine (M2M) communication and communication from machine to the MOM and ERP levels, or to the Cloud (i.e. MindSphere). Both PROFINET and OPC UA can use TSN, also an Ethernet-based technology, as a kind of “turbo power.” 


TSN enables reserved bandwidths, Quality of Service (QoS) mechanisms, low transmission latency, and parallel transmission of multiple protocols – including real-time-capable ones, in addition to dynamic plant changes using Plug&Work. There’s no need to go without the proven PROFINET services for configuration, parameterization, and diagnostics, or profiles from PROFIsafe, PROFIdrive, PROFIenergy, etc., since these are all still there, unchanged, in PROFINET over TSN.

PROFINET portfolio

Products and systems with PROFINET and OPC UA interface

Siemens consistently relies on PROFINET, the open Industrial Ethernet standard, for both the manufacturing and process industry. That’s why devices and systems communicate via PROFINET throughout Siemens’ uniquely complete automation and drive portfolio. Discover the wide range of products – right through to software solutions and tools.
PROFINET profiles

Even more freedom with the PROFINET profiles

With the PROFINET profiles, you can implement your customized automation solutions quickly and easily. PROFINET profiles specify additional manufacturer-independent characteristics and behaviors for devices and systems. Device-specific details as well as all details of communication are hidden. This ensures that the software engineering of equipment used in the machine or plant remains absolutely independent.

PROFIdrive: Implement drive concepts quickly and easily

PROFIdrive defines the device behavior and access procedures to internal device data for electric drives on PROFINET – from simple frequency converters to high-performance servo controllers. The drive interfaces are kept as simple as possible and free of technological functions.


Your advantages:

  • Uniform application interface for motion control and drive-based safety
  • Replaceability of devices
  • Diagnostics via bus


Reduce your engineering and commissioning time – with PROFIdrive!

PROFIenergy: Communication with energy saving potential

PROFIenergy supports the easy automatic disconnection and connection of technologically correlated plant parts. Coordination is realized centrally via a higher-level control. The result: considerably reduced energy costs.


Your advantages:

  • Controlled energy consumption
  • Coordinated disconnection and connection of complete plant parts
  • Elimination of the need for permanently wired external systems


Reduce your energy costs with PROFIenergy!

PROFINET truck tour

Live demonstrations of PROFINET with OPC UA and TSN

Once again in 2020, the PROFINET truck will be on the road, touring throughout Europe. Experience the benefits of PROFINET together with OPC UA and TSN up close – and discover how Industrial Ethernet standards can take your company even further forward in the age of digitalization.

Experience digitalization at first hand

How is PROFINET integrated into manufacturing and process automation systems using the TIA Portal and SIMATIC PCS 7? What would potential practical implementations of OPC UA, SIMATIC S7-1500R CPU or SIMATIC S7-1500 T-CPU and SINAMICS S210, connectivity, feeder bus systems, and flexible network infrastructure with SCALANCE, including the SINEC NMS network management system, look like? What kind of digitalization scenarios can you find in subject areas like simulation, virtualization, digital twins, and Cloud connections? In the truck vivid live demonstrations, practical examples, animations, and use cases of digitalization will clearly illustrate and explain the crucial benefits of PROFINET, OPC UA, and TSN for you. You’ll also have the chance to ask the experts any questions you may have directly. Interested? Talk to your regional PROFINET contact: Locate contact
