Profinet leads the field in industrial Ethernet protocols
A recent analysis by market research institute Omdia confirms that Profinet is the leading technology in the field of industrial Ethernet protocols. In addition to its broad market penetration, Profinet's consistent focus on security is particularly impressive - a decisive factor in times of increasing networking and digital threats.
With the publication of the Profinet specification V2.4 MU6, PI (Profibus & Profinet International) is setting an example for security-by-design. The new version contains comprehensive definitions for Security Class 2 and 3, which are specifically tailored to the requirements of modern industrial plants. These security mechanisms ensure robust networks that are protected against both external attacks and inadequate access controls. The accompanying technologies - such as GSDML - and the certification processes are also being continuously developed.
According to the association, Profinet shows its strength not only in the breadth of applications - for process automation, factory automation, high-end motion control with IRT, with the integration of IO-Link or with Ethernet-APL and Ethernet-SPE - but also in the depth of the safety concepts for safety and security. The close coordination with the other PI technologies and the commitment of over 1000 experts in the working groups ensure that safety aspects are recognized and addressed at an early stage.
In addition to Omdia, Profinet's market leadership is also confirmed by other independent studies, such as the annual analysis of the industrial networking market by HMS Networks or the market study 'Industrial Communication / Industry 4.0 2025' by Michaela Rothhöft.
