8 Communication
This section describes the PROFINET IO messaging used in communication with the drive.
For detailed information on PROFINET IO communication, refer to PROFINET specification Application Layer
protocol for decentralized periphery and distributed automation v2.0 available at www.profibus.com.

Introduction to PROFINET IO

PROFINET IO is a fieldbus protocol that enables communication between programmable controllers and
distributed field devices in Ethernet network. The protocol classifies devices into IO controllers, IO supervisors
and IO devices, which have a specific collection of services.
PROFINET IO uses three different communication channels to exchange data. The standard UDP/IP and TCP/IP
channel is used for parameterization and configuration of devices and for acyclic operations. The Real Time (RT)
channel is used for cyclic data transfer and alarms. The third channel, Isochronous Real Time (IRT) channel, is
used e.g. in motion control applications (not implemented in SI-EP3).
PROFINET IO devices are structured in slots and sub-slots, which can contain modules and sub-modules
correspondingly. Devices can have almost any number of slots and sub-slots and they can be virtual or real.
Device specific data is represented in slot 0, module and sub-module specific data in subsequent slots and sub-
slots.
