Comparison of the System and Standard Functions of PROFINET IO and PROFIBUS DP
For CPUs with an integrated PROFINET interface, the table below provides you with an
overview of:
• System and standard functions for SIMATIC that you may need to replace when
converting from PROFIBUS DP to PROFINET IO.
• New system and standard functions
