6.1 Introduction to PROFINET IO

6.1.1 Overview

PROFINET IO is a fieldbus protocol that enables communication between programma-

ble controllers and distributed field devices in Ethernet networks.

PROFINET IO uses traditional Ethernet hardware and software to define a network that

structures the task of exchanging data, alarms and diagnostics with Programmable Con

trollers and other automation controllers.

PROFINET IO can be thought of, as PROFIBUS on Ethernet. The protocol classifies de-

vices 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 configu-

ration 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 some motion

control applications (not implemented in JVL MAC00-EP4/-EP41nor the MIS/MIL/

MILxxxxxxEPxxxx motor).

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. One of the benefits of

PROFINET IO is the diagnostics and alarm mechanism. Every module and sub-module

provides alarm data to the IO controller using the cyclic channel. Diagnostic data can be

read non-cyclically from the device by using record data. Properties and services of a

PROFINET IO device are described in a GSD file that is written in GSDML (General Sta

tion Description Markup Language).
