Openness, flexibility, efficiency, performance

Productivity to the power of four –
and simple transition

PROFINET give you new ways to boost your productivity with four decisive advantages – openness, flexibility, efficiency, and performance. Also learn how simply you can transition from your existing PROFIBUS solution to PROFINET.

PROFINET: the Ethernet standard for professionals

Siemens uses the Ethernet standard for automation with PROFINET. PROFINET enables quick and secure data exchange on all platforms and creates the possibility of realizing innovative concepts for the production and processing industries. Due to its openness and flexibility, PROFINET offers users a

a high amount of freedom when designing machine and system structure.


PROFINET’s efficiency ensures that the user’s available resources are optimally used and that system availability is increased significantly. Innovative products from Siemens and the performance of PROFINET sustainably increase productivity in the company.


Consistent openness today and tomorrow

PROFINET embodies the idea of enabling manufacturer-independent automation solutions with an open standard. PROFINET is 100 percent Industrial Ethernet – the standard that has been established in industrial communications since the 1990s.

Consistent, end-to-end communication via a unified standard

Thanks to its openness, PROFINET creates the basis for a uniform machine/plant automation network to which automation devices and standard Ethernet devices can be connected.

Connectivity and interoperability with componentsfrom various manufacturers

No matter which components you want to use for your automation solution, PROFINET enables configurations that are independent of the type of controller and other nodes.

Simple integration of existing systems

PROFINET also protects your existing PROFIBUS investments. For instance, you can easily convert a SIMATIC ET 200SP controller to PROFINET by replacing an interface module and adapting the configuration. Or seamlessly integrate entire PROFIBUS networks simultaneously into PROFINET via the IE/PB LINK PN IO.

Use of standard web services with PROFINET

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 and greatly simplifies commissioning and diagnostics. Taking into account security mechanisms, this approach allows the introduction of new remote maintenance concepts or even the rapid exchange of production. This is the correct path to digitalisation.

PROFINET – innovative thanks to continuous further development

PROFINET characteristics such as deterministic responses, hard real-time capability in the microsecond range, and integrated diagnostic capability are the ideal foundations for Industry 4.0 communication. At the same time, PROFINET harmonizes perfectly with cutting-edge standards such as OPC UA. And thanks to PROFINET’s full IEEE conformity, you benefit from all further developments of Industrial Ethernet in terms of bandwidths, speed, security, and performance. PROFINET is a defined standard (IEC 61158/61784).
