Introduction to PROFINET

What is PROFINET IO?

Within the framework of Totally Integrated Automation (TIA), PROFINET IO is the logical

further development of:

● PROFIBUS DP, the established fieldbus and

● Industrial Ethernet

PROFINET IO is based on 20 years of experience with the successful PROFIBUS DP and

combines the normal user operations with the simultaneous use of innovative concepts of

Ethernet technology. This ensures the integration of PROFIBUS DP into the PROFINET

world.

PROFINET IO as the Ethernet-based automation standard of PROFIBUS/PROFINET

International defines a cross-vendor communication, automation, and engineering model.

Objectives of PROFINET

The objectives of PROFINET:

● Industrial networking, based on Industrial Ethernet (open Ethernet standard)

● Compatibility of Industrial Ethernet and standard Ethernet components

● High robustness due to Industrial Ethernet devices. Industrial Ethernet devices are suited

to the industrial environment (temperature, noise immunity, etc.).

● Use of IT standards such as TCP/IP, http.

● Real-time capability

● Seamless integration of other fieldbus systems
