PROFINET

PROFINET

Function

PROFINET is the open Industrial Ethernet standard of PROFIBUS International for automation systems. PROFINET is based on Industrial Ethernet and uses TCP/IP and IT standards.

Versions of PROFINET:

• PROFINET CBA (component based automation) for networking distributed plants, component engineering
• PROFINET IO (input output) for controlling actuators, sensors and drives using one or several central controllers

PROFINET is supported by PROFIBUS International and has been included in standards IEC 61158 and IEC 61784 since 2003.

PROFINET includes:

• Multi-level real-time concept
• Simple field devices, which operate IOs directly on Ethernet
• Design of modular systems with a high degree of reusability
• Simple integration of existing PROFIBUS or Interbus systems

Benefits

• Openness offers flexibility for future innovations
• Greater freedom to implement tailored machine and plant concepts
• Unequaled efficiency allows optimum utilization of resources
• Unique performance ensures high precision and product quality
• Sustained increase in productivity
