Blocks in PROFINET IO

Content of this Section
This section explains the following:
• Which blocks are intended for PROFINET
• Which blocks are intended for PROFIBUS DP
• Which blocks are intended for both PROFINET IO and PROFIBUS DP
Compatibility of the New Blocks
For PROFINET IO, it was necessary to create some new blocks, among other things,
because larger configurations are now possible with PROFINET. You can also use the new
blocks with PROFIBUS.
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
• New system and standard functions

Blocks
SFC 12 (deactivation and
activation of DP slaves/IO
devices)
SFC 13 (read diagnostic data of
a DP slave)
SFC 58/59 (write/read data
record in I/O)
