The field bus systems have been applied to the industrial automation. PROFINET is an optimized industrial network standard. It provides the service definition and protocols for real-time communication based on Ethernet. The basic characteristics and protocol analysis are presented in this paper. This paper depicts a topology model using Wire shark and Siemens PLC to capture PROFINET IO communication...
