PROFINET Distributed I/O

The focus of PROFINET IO is to have cyclic data exchange between a controller and multiple often simple

PROFIBUS fieldbus has been integrated into the PROFINET IO from user's point of view.
The PROFINET IO distinguishes the following different device roles. Please note a single device can have
