PROFINET – Open Industrial
Ethernet standard for automation
As a leading and innovative global supplier
of industrial automation systems, Omron delivers
equipment for installations throughout the world.
Recognising that needs differ between users,
applications and countries, Omron pursues
an open-standards policy that has proved to be the
key to success. This extends to networking and
connectivity, where we are constantly increasing
our scope. Omron played a pioneering role,
e.g. in developing DeviceNet and CompoNet and
in addition to offering a wide range of products
for CIP-based networks we actively
support PROFIBUS-DP, by far the world’s
most popular system.
Networks, the next generation
Building on our experience with PROFIBUS, Omron
is now a front runner in the support and development
of PROFINET-IO, an open ‘Industrial Ethernet’ solution
set to become Europe’s next-generation field network.
PROFINET-IO meets all requirements of industrial
automation and provides the higher speeds necessary
as intelligent devices become more complex.
PROFINET is more adaptable than conventional bus
systems, enabling users to optimize it for their own
required functionality. Today, Omron is a leader in
bringing PROFINET-compatible modules to the market.
PROFINET cyclic data and standard
UDP or TCP/IP data can share
one cable.

Built-in switches cut cost
Conventionally, Ethernet networks use a star topology, which
requires extra hardware (switches) to interconnect devices.
Omron’s SmartSlice PROFINET-IO Unit gives the option
of linking devices in the conventional line topology used with
most field buses. No additional hardware is needed.
Making use of field devices with an integrated switching
function is a very efficient and cost-saving method that
minimizes the bill of materials and saves on installation costs.
It also facilitates easy system extension in the accustomed
manner when the time arises.
No need to install an industrial
ethernet switch in every control
cabinet.
up to 100 metres between stations
Making Industrial Ethernet easy
PROFINET-IO offers many advantages for both system
integrators and equipment/machinery manufacturers.
Combining the ease of use of PROFIBUS-DP with
a standard Ethernet physical layer, PROFINET-IO offers
the increased speed, easier management of ever-
increasing amounts of device data, and openness for
integrating standard Ethernet data communication.
PROFINET-IO has standardized functions for
parameterization, diagnostics and alarms which are
far more extensive than in conventional bus systems.
To manage this high functionality, OMRON provides
FDT-based software tools, which make PROFINET-IO
as easy to use as a conventional fieldbus system.

High availability by ring redundancy
Naturally, PROFINET is inherently reliable in its own right,
but increased reliability of the network connection can
be achieved by closing the line structure to form a ring.
The advantage of a ring structure is that any single cable
failure or malfunction in one device will not lead to
a disruption in communication between other connected
devices. This highly secure method requires one device in
the ring to be a redundancy manager supporting the MRP
(Media Redundancy Protocol) as prescribed in the PROFINET
specification, to assure operation of all devices supporting
ring redundancy.
MRP included
Omron’s SmartSlice remote I/O stations support the MRP
protocol as redundancy clients. They report the status of their
communication connections to the MRP manager. In case
of a connection failure, the MRP manager will activate the
alternative communication path, so that all stations remain
accessible. By including the SmartSlice stations as active
members of the ring, the number of dedicated switches
needed to build a redundancy ring is greatly reduced.

advantages today

MRP clients report interruptions
to the MRP manager, which
activates the stand-by connection
in milliseconds.
Case study: Marine applications
Control system design for ships is going through a rapid
change towards fully integrated automation systems.
Monitoring and control of e.g. power generation, HVAC, pumps
and winches are made fully transparent, and remotely
accessible. Controller- and network redundancy, and toolless
unit replacement are key features of Omron’s PROFINET
solution to ensure maximum system availability.

PROFINET – easy to set up,
with open software tools
Omron products support PROFINET-IO for cyclic master-slave
communication with ‘soft’ real-time characteristics, as
required in general-purpose industrial automation. The most
universal PROFINET variant, PROFINET-IO is similar to fieldbus
communication and offers added flexibility while remaining
easy to use.
One tool for all networks
Ease of use is the key to PROFINET’s success. And if you
currently use Omron’s highly popular CX-One software, you
already own the configuration tools. The network-independent
FDT technology Omron already uses for its PROFIBUS
configuration tool also supports PROFINET.
With PROFIBUS-DP interface units for all main product series
Omron has already integrated PROFIBUS in its ‘Smart
Platform’ solutions. Moreover, Omron’s FDT-based
configuration software, which is open to third-party devices,
offers full access to any parameter in any device,
at any time.
FDT is Open Technology
An FDT program (Field Device Tool) is a network-independent
framework that accepts product-specific plugins from any
vendor provided it is FDT compliant. Called DTMs (Device Type
Managers), these plugins provide a user interface for setting
up and maintaining a device, and handle the communication
over the network. This technology eliminates the need to learn
how to use a new tool when changing bus systems and allows
access to the device-specific features of each vendor’s device
via its own dedicated interface.
Any device that is not provided with a DTM can be configured
using conventional text-based GSDML (XML) files.

FDT Group
The FDT Group is an open, independent collaboration
of international companies dedicated to establishing FDT
technology as an international standard within the
automation industry. FDT technology standardizes the
software interface between field devices and engineering
systems. The key feature is its independence from the
communication protocol and the software environment
of either the device or the host system. FDT allows any
device to be accessed from any host through any protocol.

PROFINET-IO controller CJ1W-PNT21
This module is designed for use with any CPU unit belonging
to Omron’s highly successful CJ series of programmable logic
controllers. It uses a separate communication processor to
guarantee reliable, high-level performance independent of the
PLC program or its CPU speed. As it is transparent to Omron’s
own FINS communication protocol, the PROFINET IO controller
also provides a communication channel so that legacy devices
or existing software tools can be used to exchange data with
the PLC CPU through the PROFINET controller.
PROFINET-IO device GRT1-PNT
This communication interface for Omron’s SmartSlice remote
I/O system allows up to  SmartSlice units to be mounted per
station. SmartSlice has built-in intelligence that helps users
to reduce engineering time by autonomously monitoring
machine status and performance to help schedule preventive
maintenance. The PROFINET-IO device has two external
network connections to allow direct linking of multiple devices
in a line structure. Built-in support for MRP (Medium
Redundancy Protocol) allows these units to be installed as
an integral part of a redundant ring topology. An optional
dedicated memory end plate allows on-site unit replacement
without the need to reconfigure settings. For more

PROFIBUS & PROFINET International (PI)
PI is the international industrial communications
community responsible for PROFINET and PROFIBUS,
two of the most important technologies used
in factory- and process automation today. Sales of
PROFIBUS nodes has passed the  million mark and
currently more than  PI member companies
around the world develop and supply products,
services and solutions for industrial automation
applications. The PI commitment to openness and
standardization guarantees a wide choice of
interchangeable products and stimulates innovation,
ensuring best-in-class performance. And with
