1.1 What is PROFINET?

General
PROFINET is an open standard for Industrial Ethernet. PROFINET satisfies
requirements for automation technology. PROFINET solutions can be implemented
for factory and process automation, for safety applications, and for the entire range
of drive technology right up to clock-synchronized motion control.
Standardization
The use of open standards, simple operation, and the integration of existing system
segments have driven the definition of PROFINET from the beginning. PROFINET
is standardized in IEC 61158 and IEC 61784. The continual further development
of PROFINET offers users a long term perspective for the implementation of their
automation tasks.
Communication profiles
PROFINET has a modular design and different PROFINET communication profiles
are all combinations of modular elements from the groups transmission technology,
communication protocol, and application profiles.
Here are some examples of PROFINET communication profiles:
Application manual - PROFINET Controller/Device
3HAC050969-001 Revision: G
• PROFINET-IO - Distributed I/O (Remote I/O). Here, the familiar I/O view of
PROFIBUS is retained, in which the user data from the field devices are
periodically transmitted into the process model of the control system.
• PROFINET-CBA - Based on the object-oriented modelling of technological
modules. Based on the object model, machines and installations are
structured in PROFINET in the form of technological modules.
• PROFIsafe - Defines how safety-oriented devices (emergency shutoff
switches, light grids, overfill protection systems, etc.) can communicate
safety control information over a network securely enough that they can be
used in safety-oriented automation tasks up to EN954's KAT4, AK6, or SIL3
(Safety Integrity Level).
• PROFIdrive - The PROFIdrive profile covers application scenarios from simple
frequency converters to highly dynamic servo drivers.
• PROFIenergy - A profile of the PROFINET communications protocol that
allows the power consumption of automation equipment in manufacturing
(such as robot assembly cells, laser cutters and sub-systems such as paint
lines) to be managed over a PROFINET network. It offers an open and
standardized means of controlling energy usage during planned and
unplanned breaks in production. See also Application manual - PROFIenergy
Device.
