1. Introduction to PROFINET Bus     

PROFINET, launched by PROFIBUSInternational (PI), is a new generation automation bus standard based on industrial Ethernet technology. As a strategic technological innovation, PROFINET provides a complete network solution for the field of automation communication, including real-time Ethernet, motion control, distributed automation, fault safety, network security and other hot topics in the field of automation, and as a cross-vendor industrial bus technology, It is fully compatible with industrial Ethernet and existing fieldbus (such as PROFIBUS) technologies, protecting existing investments.

PROFINET bus has the following technical characteristics:

① Good compatibility, suitable for solving the compatibility and interoperability problems of devices from different manufacturers in the system;

② High data transmission efficiency, long transmission distance, with an adaptive transmission rate of 10 ~ 100M/bps;

③ Strong anti-interference ability, adapt to the harsh industrial production environment;

④ Fast network fault location and diagnosis.
