Frequently asked questions

How can I use PROFINET in the manufacturing industry?

PROFINET enables high product quality and reliability from single machines to entire production plants through fast, deterministic real-time communication and integrated safety and diagnostic functions.

In machine building, it supports cycles as fast as 31.25 µs, large quantity structures with up to 512 stations per network and fast start-up under 500 milliseconds. Innovative machine concepts are possible with only a single cable for all I/O and Ethernet communications without compromising machine safety.

In plant engineering, PROFINET reduces complexity, enables centralized engineering for the entire process and provides maximum flexibility for building, renovating or reusing plant sections.

How can PROFINET be used in the process industry?

PROFINET delivers end-to-end and secure communication across process plants, enabling fast, reliable exchange of critical process data through redundant ring structures, comprehensive device and network diagnostics, and functional safety with PROFIsafe.

It supports industries from oil production to wastewater treatment, rolling mills and solar panel manufacturing, offering greater flexibility, simpler operation and additional redundancy options. Extended features — such as online updates, proxy technologies, and redundancy functions — help maintain high plant availability and cost-effective processes.
