Figure 3-1 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.
