10.4PROFINET IO
PROFINET IO uses cyclic data transfer to exchange data with programmable controllers over
Ethernet. In fact, it can be thought of as PROFIBUS on Ethernet.
The data exchanged is organised as slots containing modules (that contain I/O points). The
programmable controller and the device it is communicating with must understand the
structure and meaning of the data being exchanged. This is accomplished using GSDML files
(see 10.5 GSDML files).
