PROFINET Network
Components
PROFINET Networks consist of several discrete items
of apparatus:-
 IO Controllers (IOC’s) – The devices actually
controlling the communications – these are
usually PLC’s.
 IO Devices (IOD’s) – These are the plant-based
devices that the IOC is communicating with.
They may be remote IO, Invertor drives,
encoders etc.
 Switches – These are used to connect the IOC’s
with the IOD’s.
 Monitoring Tools – Essential for the qualification
and support of your network
 Gateways – These are used to connect to other
network types, e.g. PROFIBUS, AS-I, CAN or IOT
(OPC-UA/MQTT)

Gateways and Couplers
 PROFINET Gateways and Couplers are physical devices that
facilitate communication between two separate industrial
networks, at least one of which will be PROFINET.
 PROFINET Gateways generally act as a IO device on the
PROFINET side and as a controlling device (Master) on the sub
network.
 PROFINET Couplers generally interface two separate networks,
each having their own IO Controller or Master.
 On the PROFINET side, the gateway will appear as an IO Device
and will have a GSDML file, to allow it to be incorporated into
the hardware configuration of an IO Controller (PLC).
 Gateways are available for a wide range of network
combinations including PROFIBUS (DP), PROFIBUS (PA), AS-i,
CanBUS, IO Link and many more.

PN-PN Coupler Configuration
 The GSDML file of the coupler needs to be
added to the hardware configuration of the
IO Controller in each network.
 The device must be given a device name and
IP address.
 The modules on each side appear as inputs
and outputs of varying sizes.
 Output channels on one side must match
input channels on another.

PROFINET – PROFIBUS DP
Coupler
 A PROFINET to PROFIBUS DP Coupler facilitates bi-directional
communication between a PROFINET Network and a PROFIBUS DP
network.
 It will be supplied with a GSDML file and a GSD file for
incorporation into the respective Hardware Configuration of the
IO Controller and PROFIBUS Master respectively.
 The PROFIBUS DP side of the gateway will need a slave address.

(PROFINET Side)
 The GSDML file of the gateway needs to be
added to the hardware configuration of the
IO Controller on the PROFINET side.
 Output channels on the PROFINET side must
match input channels on the PROFIBUS DP
side.

PN-PB DP Configuration
(PROFIBUS Side)
 The GSD file of the gateway needs to be
added to the hardware configuration of the
DP Master on the PROFIBUS side.
 Output channels on the PROFIBUS DP side
must match input channels on the PROFINET
side.

PROFINET – PROFIBUS PA
Gateways
 A PROFINET to PROFIBUS PA Gateways facilitates bi-directional
communication between a PROFINET Network and a PROFIBUS PA
network.
 Here, the Gateway is acting as a PA Master on the PA side.
 The configuration of these devices is a little more time-
consuming as it requires the creation on an application-specific
GSDML file.

PN-PB PA Configuration
An application-specific GSDML file needs to be created for
inclusion in the Hardware Configuration of the PROFINET IO
Controller. This maps PA GSD files with PN slots.

PROFINET – AS-i Gateways
 PROFINET to AS-i Gateways facilitate bi-directional
communications between a PROFINET network and an AS-I
Network.
 They are available as a stand-alone PN-AS-i Master or as a
module that plugs into a PLC rack.
 Stand-alone devices must be supplied with a GSDML file for
inclusion in the Hardware Configuration of the IO Controller
on the PROFINET side.

14. PROFINET Gateways – V1.1 © Control Specialists Ltd – November 2021 CSL GW.14
PN-AS-I Configuration
 AS-I Gateways are easier to configure
than those associated with higher-
level networks like PROFINET and
PROFIBUS.
 This is because AS-i devices do not
have any form of device description
file.
 Stand—alone PROFINET-AS-i gateways
work on the principle of mapping a
module slot number on the PN side
with an AS-i address (1-31).
 PLC AS-I modules simply need to know
the number of individual AS-i devices
they will communicate with and the
address of each device.

PROFINET – IO-LINK Gateways
 PROFINET to IO-Link Gateways facilitate bi-directional
communications between a PROFINET network and an IO-Link
Network.
 They are available as a stand-alone device or as a module that
plugs into a PLC rack.
 Stand-alone devices must be supplied with a GSDML file for
inclusion in the Hardware Configuration of the IO Controller
on the PROFINET side.

IIoT Gateways
 IIoT Gateways (Industrial Internet
of Things) are devices that
facilitate the transfer of non-real
time data between an operational
network (OT) ,like PROFINET, and
an IT network.
 The main uses of IIoT is either for
machine-machine or machine-
cloud data communication.
 Two of the most common
protocols currently used by IIoT
applications are OPC-UA (Unified
Architecture) and MQTT (Message
Queuing Telemetry Transport)
 Many PLCs and PROFINET
diagnostic tools support OPC-UA
and MQTT.

Demonstration
 A new Gateway has come onto the
market that allows a PROFINET IO
Controller to control PROFIBUS DP
Slaves.
 It is called a GW PN/DP 1E/1DB9
from Phoenix Contact.
 It is a din-rail-mounted device
requiring 24v dc supply and has two
interfaces, one for PROFINET and
one for PROFIBUS DP.
 This is not the same as the PN/DP
coupler mentioned earlier in that
this devices acts as a PROFOBUS
Class 1 Master.
