Extent of PROFINET IO and Component-Based Automation
Component-Based Automation organizes the system structure based on the various
functions. These functions are configured and programmed.
PROFINET IO provides you with a view of the system that is very similar to the view
obtained in PROFIBUS. You continue to configure and program the individual automation
devices.
Further Information
For further information on PROFINET IO and PROFINET CBA, refer to the
PROFINET
System Description. Differences between PROFIBUS DP and PROFINET IO and their
common features are described in the
From PROFIBUS DP to PROFINET IO Programming
Manual.
For detailed information on PROFINET CBA, refer to the SIMATIC IMAP and Component-
Based Automation documentation.
