Profinet is the leading open industrial Ethernet protocol standard in Europe for all areas of industrial automation technology. This type of communication system enables data to be exchanged in real-time between controller devices and field devices using industrial Ethernet. Profinet is the successor to PROFIBUS®, a Fieldbus protocol standard which is standardised by the PROFIBUS & PROFINET International (PI) user organisation. LAPP is playing an active role in further developing Profinet.
