Figure 3-1 Extent of PROFINET IO and Component-Based Automation
Component Based Automation divides the entire system into 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.
Reference
Further Information
• on PROFINET IO and PROFINET CBA is available in the
PROFINET system
specification.
For differences and similarities between PROFIBUS DP and PROFINET IO, refer to the
From PROFIBUS DP to PROFINET IO programming manual.
• For further information about PROFINET CBA, refer to the documentation on
SIMATIC iMAP and Component Based Automation.
