2 PROFINET

PROFINET is an Industrial Protocol managed by the PROFIBUS and PROFINET International group (PI). It is an application-level protocol based on Ethernet, that is a successor of the PROFIBUS protocol. PROFINET is realized on AM26x microcontrollers using the PRU ICSS switch. PROFINET supports different classes based on the cycle time requirement. Class A provides a cycle time down to 100ms. PROFINET-RT, referred to as Class B, supports a cycle time down to 1 ms. PROFINET-IRT, supported by Class C is known for isochronous real-time, supports cycle time down to 250us. TI AM26x series of microcontrollers supports all PROFINET classes. The Pre-certified PROFINET RT/IRT software solution and hardware from TI , enable faster time to production.
