PROFINET
Within the framework of Totally Integrated Automation (TIA), PROFINET represents a
consequent enhancement of:
• PROFIBUS DP, the established fieldbus and
• Industrial Ethernet, the communication bus for the cell level
Experience gained from both systems was and is being integrated into PROFINET.
PROFINET is an Ethernet-based automation standard of PROFIBUS International
(previously PROFIBUS Users Organization e.V.), and defines a multi-vendor communication,
automation, and engineering model.
