• CPUs as of Firmware 2.3.0 (for example CPU 315-2 PN/DP)
• STEP 7, as of Version 5.3 + Service Pack 1
Reference
You will find information on the topic of PROFINET in the following sources:
• in the
System Description PROFINET
• in the
From PROFIBUS DP to PROFINET IO programming manual. This manual also
lists the new PROFINET blocks and system status lists.

Chapter Content
This chapter 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 these
new blocks with PROFIBUS.
