Profinet

The Profinet protocol may require root permissions in some constellations. If you experience problems with running this protocol, please make sure to install your service on an agent with root permissions as described in agent orchestration.

Overview

Profinet (usually styled as PROFINET, as a portmanteau for Process Field Net) is an industry technical standard for data communication over Industrial Ethernet, designed for collecting data from, and controlling equipment in industrial systems, with a particular strength in delivering data under tight time constraints.

This protocol is optional and subject to license. It should be installed on demand.
