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.
