PN/PN coupler
Installation and Operating Manual, 06/2010, A5E00717043-04 9
Description 1
1.1 Application and function
Application
The PN/PN coupler is used to link two Ethernet subnets with one another and to exchange
data. That way use data about input or output address areas or datasets can be used. The
maximum size of the transferable input and output data is 1024 bytes. The division into input
and output data is preferable, so that e.g. 800 byte input data and 200 byte output data can
be configured.
As a device, the PN/PN coupler has two PROFINET interfaces, each of which is linked to
one subnet.
In the configuration, two IO Devices are produced from this one PN/PN coupler which means
that there is one IO Device for each station with its own subnet. The other part of PN/PN
coupler in each case is known as the bus node. Once configuring is complete, the two parts
are joined.

Principle of operation
● Data exchange with I/O modules
Through the configured inputs of a slot, the local CPU reads the values that the CPU of
the other subnet writes over the configured outputs of the coupling partner.
Through the configured outputs of a slot, the local CPU writes values that the CPU of the
other subnet receives over the configured inputs of the coupling partner.
● Data record transfer
The module types Publisher und Storage address the DS task through module addresses
during the dataset transfer.

Configuring
You either configure the PN/PN coupler using STEP 7 or a configuring tool which uses a
GSD file to integrate the PN/PN coupler.
You configure the I/O areas using virtual modules that are inserted from the hardware
catalog in HW Config onto slots of the PN/PN coupler, as real modules.
You select the I/O modules for the PN/PN coupler required for your application with STEP 7
in HW-Config in the hardware catalog. The output data of one side of the PN/PN coupler is
transferred as the input data of the other side and vice versa.
In dataset modules, dataset transfers take place between both PROFINET IO subnets. On
the X1 and X2 page, pairs of mutually fitting dataset module types must be configured on
equal slots, thus RD WRITE STO and RD READ STO or RD WRITE PUB and
RD READ PUB.
The input and output data are used to control the dataset transfer.

Assembling 2
2.1 Assembly rules
Mounting position
You can mount the PN/PN coupler in any position. Please note that the maximum ambient
temperature for horizontal mounting positions is 60 °C while that for all other positions is
40 °C.
You will find more information on operating conditions in Appendix Technical data (Page 79).
Open component
The PN/PN coupler is an open component. In other words, you may only set it up in
enclosures, cabinets or electrical service rooms. These should only be accessible by means
of a key or a special tool. Only trained or authorized personnel may have access to the
enclosures, cabinets or electrical service rooms.
Technical setup
Mount the PN/PN coupler on a DIN rail (7.5 mm and 15 mm). Ensure a space of 40 mm both
above and below the module for unimpeded assembly.
2.2 Assembling the PN/PN coupler
Components required
● PN/PN coupler
● Mounting rail:
– DIN rail (7.5 mm) or
– DIN rail (15 mm)
The order numbers for the components can be found in Appendix Order numbers and
accessories (Page 89).

Assembling
2.3 Disassembling the PN/PN coupler
PN/PN coupler
16 Installation and Operating Manual, 06/2010, A5E00717043-04
Assembling PN/PN coupler on DIN rail
1. Assemble the DIN rail such that there is enough space to assemble and heat the
modules (at least 40 mm above and below the modules). If you want to swap the
SIMATIC Micro Memory Card once the PN/PN coupler is assembled, you will have to
leave additional space for this.
2. Fit the PN/PN coupler in the DIN rail and swing it down.
3. Wire the PN/PN coupler as described in Chapter Connecting (Page 19).
Note
If the assembly base is a grounded metal plate or a grounded equipment mounting plate,
then you must ensure a low-ohm connection between the DIN rail and base. E.g. with
painted or anodized metals, use a suitable contacting agent or contact washers.
2.3 Disassembling the PN/PN coupler
Disassembling the PN/PN coupler
1. Switch off the PN/PN coupler's power supply.
2. Loosen the connections and bus connectors on the PN/PN coupler.
3. Use a screwdriver to push down the slide valve on the underneath of the PN/PN coupler.
4. With the slide valve still pressed down, swing the PN/PN coupler out of the mounting rail.

Installation and Operating Manual, 06/2010, A5E00717043-04 17
2.4 Assembling-color plates
Introduction
The color-coding plates allow you to individually color code the PROFINET IO interfaces in
accordance with company and national regulations. The color-coding plates are available in
white, red, yellow, yellow-green, brown, blue and turquoise. You can provide every
PROFINET IO interface on the PN/PN coupler with a color-coding plate.
The color-coding plates are positioned on the bottom right of each PROFINET IO interface.
Required tool
Screwdriver 3.5 mm blade width
Assembling color-coding plates
1. Use the screwdriver to push the spigot of the color-coding plate into the opening provided
for this in the PN/PN coupler.
2. Secure the color-coding plate as described below.
3. Bend the star-shaped support up by approx. 30° to 40°.
4. Detach the color-coding plate by moving the support this way and that.
Disassembling color-coding plates
Use a screwdriver to lever the color-coding plates from their supports.

Connecting 3
3.1 Electrical isolation and grounding
3.1.1 Introduction
Redundant 24 V DC power supply
You can connect the PN/PN coupler to two independent 24 V DC power supplies. Only one
24 V DC power supply is ever active at any one time. If one power supply fails, the other
automatically becomes active. During parameterization, you identify which power supplies
(PS1, PS2 or both) are connected and are to be diagnosed. You need only connect up one
24 V DC power supply to operate the PN/PN coupler.
Properties of the PN/PN coupler
● Both PROFINET IO subnets are electrically isolated from one another.
● Both PROFINET IO subnets are electrically isolated from the 24 V DC power supply.
● Both 24 V DC power supplies are electrically isolated from one another.
● The PROFINET IO subnet to X1 and the logic of the PN/PN coupler are electrically
linked.
Ungrounded incoming supply
Non-grounded operation of the PN/PN coupler is possible with a 24 V DC power supply.

3.1.2 General operating rules and regulations
Introduction
If they are part of plants or systems the modules described require adherence to specific
rules and regulations depending on the application.
The most important rules, which you must observe for safe integration into a plant or system,
are listed below.
Specific application
Please observe the safety and accident prevention regulations applying to specific
applications (e.g. machine protection guidelines).
EMERGENCY STOP equipment
EMERGENCY STOP devices according to IEC 6204 (coincides with VDE 113) must remain
effective during all operating modes of the plant or system.
System startup after certain events
The table below identifies situations you must pay attention to when the system starts up
after the occurrence of certain events.
When ... ...
starting up after a voltage dip or
power failure,
starting up after bus communication
has been interrupted,
no dangerous operating states may occur. If necessary
actuate an EMERGENCY-STOP!
starting up after unlocking the
emergency stop device,
starting up without the IO Controller
activating the IO Devices,
the start up must always be controlled and defined.
