C H A P T E R 9 Configuring PROFINET This chapter describes how to configure the PROFINET feature on the Cisco IE 3000 switch. • Understanding PROFINET, 1 • Configuring PROFINET, 4 • Displaying the PROFINET Configuration, 5 • Troubleshooting PROFINET, 5 Understanding PROFINET PROFINET is the PROFIBUS International (PI) open Industrial Ethernet Standard that uses TCP/IP and IT standards for automation control. PROFINET is particularly useful for industrial automation systems and process control networks, in which motion control and precision control of instrumentation and test equipment are important. It emphasizes data exchange and defines communication paths to meet speed requirements. PROFINET communication is scalable on three levels: • Normal non-real-time communication uses TCP/IP and enables bus cycle times of approximately 100 ms. • Real-time communication enables cycle times of approximately 10 ms. • Isochronous real-time communication enables cycle times of approximately 1 ms. Note The switch does not support isochronous real-time communication channels. PROFINET IO is a modular communication framework for distributed automation applications. PROFINET IO uses cyclic data transfer to exchange data, alarms, and diagnostic information with programmable controllers, input/output (I/O) devices, and other automation controllers (for example, motion controllers).
