PROFINET is known as the “all-encompassing Industrial Ethernet” since it can be used in every aspect of automation: discrete, process, motion, peer-to-peer integration, vertical integration, safety, and more.
PROFINET (for Process Field Network) is an industry technical standard for data communication over Industrial Ethernet. It’s designed for collecting data from, and controlling, equipment in industrial systems, with a particular strength in delivering data under tight time constraints (on the order of 1ms or less). PROFINET was developed by Siemens and the PROFIBUS User Organization, and the standard is maintained and supported by PROFIBUS & PROFINET International, an umbrella organization headquartered in Karlsruhe, Germany. PROFINET is standardized in IEC 61158 and IEC 61784. PROFINET products are certified by the PNO user organization, guaranteeing worldwide compatibility.
