§4.4 – PROFINET Features vs. PROFIBUS

PROFINET offers much higher performance than PROFIBUS and other fieldbuses in terms of:

  • Unlimited scalability
  • Unlimited address space
  • Larger message size (1440 bytes vs. 244)
  • Machine 2 Machine (M2M) communication
  • Vertical integration capabilities
  • The possibility to coordinates more drive axes (32 axes vs. >150) – with IRT updates in 1 ms range, with less than 1 us jitter
  • It’s faster too, which means more application potential and fewer interfaces
