PROFINET, introduced by PROFIBUS international organization, is a new generation of automation bus standard based on Industrial Ethernet technology.

Profinet ethernet provides a complete network solution for the field of automation communication, including hot topics in the field of automation such as real-time Ethernet, motion control, distributed automation, fault security and network security. Moreover, as a cross vendor technology, it can be fully compatible with industrial Ethernet and existing field bus (such as PROFIBUS) technology to protect the existing investment.

In order to achieve the above communication function, the following three communication protocol levels are defined.

·TCP / IP is designed for PROFINET CBA and factory commissioning, and its response time is about 100ms.
·RT (real time) protocol is for the application of PROFINET CBA and PROFINET IO, and its response time is less than 10ms.
·IRT (isochronous real-time) communication protocol is designed for PROFINET IO communication of drive system, and its response time is less than 1ms.

The packet of PROFINET protocol can be recorded and displayed by the analysis tool of profinet ethernet. There are also some software that can interpret PROFINET data frames.
