Description
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.

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.

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.

Perform a strain relief in the PROFINET connection cable in case of environment conditions
with oscillations of shocks.
To do this you require a cable tie with a standard width of 2.5 mm or 3.6 mm. Use it to attach
the PROFINET connecting cable from right where it exits the PROFINET connector to the
cable bracket provided on the Interface module (on the front side directly below the
PROFINET IO interface).

Required tool
In order to connect the power supply, you will need a screwdriver with a 3 mm blade width.
Power supply unit
You may only use PELV-type power supply units with a guaranteed electrically isolated
extra-low voltage (≤ 60 VDC).
Redundant power supply
You can supply the PN/PN coupler from two voltage sources (redundant power supply):
● If one voltage source fails, the PN/PN coupler automatically changes over to the other
voltage source.
● If both connections (PS1 / PS2) are energized, the PN/PN coupler will automatically use
the PS1 voltage source.
● If you only connect the PN/PN coupler to one power supply, you should preferably use
PS1.
Note
You can use the diagnostics to assess whether the PN/PN coupler is connected to both
24 V DC power supplies.

The maximum cross-section of the connection is 2.5 mm2. There is no strain relief. The
connecting plug allows you to loop on the power supply with no interrupts even when
removed.
Procedure
1. Strip the wires to a length of 10 mm.
2. Insert line into round opening on connecting plug until stop is reached. (In its delivery
condition, the connecting plug is plugged into the power supply connection.)
If you have a redundant PN/PN coupler power supply, connect a second power supply to
the second connecting plug.
If you only use one voltage source, you should preferably use PS1.
3. Plug the wired connecting plug(s) on to the power supply connection on the PN/PN

Configuring the PN/PN coupler with STEP 7
Introduction
Configure the PN/PN coupler with STEP 7 for standard operations.
● If you are configuring both subnets in a project or multiproject, then support STEP 7 in the
correct configuration.
● If you have split the two subnets into two STEP 7 projects, you will have to configure the
PN/PN coupler separately in each of the two projects.
NOTICE
Allocation of the virtual models
Pay attention to the allowed allocation of the modules when coupling the two subnets:
An module of the same length must be configured at the same slot in another subnet for
each input module in a subnet.

4.2 Configuring the PN/PN coupler with STEP 7
Configuring the PN/PN coupler
1. Start STEP 7 with your project and open the HW configuration.
2. From the hardware catalog, directory PROFINET IO\Gateway\PN/PN
Coupler\PN/PN Coupler V3.0, drag the PN/PN coupler X1 to the PROFINET network.
3. Double-click on the PN/PN coupler symbol.
4. Give the PN/PN coupler a device name and confirm by clicking on "OK".
This device name must be unique on the Ethernet subnet. The device name must satisfy
the DNS conventions. You will find more information about issuing device names in the
online help for STEP 7.
5. To configure the left end of the bus (X1), click the PN/PN coupler symbol.
The PN/PN coupler's 16 slots appear in the station window in the bottom section of HW
configuration.
6. Start by assigning a module from the "PN/PN Coupler V3.0 / PN/PN Coupler X1" folder in
the hardware catalog in HW Config to the slots, starting with slot 1.
7. In the "Addresses" tab of the module, select the start addresses of the inputs and outputs.
8. Confirm your entries by clicking on "OK".
Note
Configure the bus ends separately
In order to operate the PN/PN coupler, the left bus end (X1) and right bus end (X2) must
always be separately configured and these may also be located in different projects.
Make sure that you have loaded the configuration to the correct end of the bus, X1 and
X2, in each case. Configuration with an incorrect assignment will be rejected by the bus
end of the PN/PN coupler in question.
Note
Assign device name
Assign the device name to the PN/PN coupler online.
Result
Configuration for one end of the PN/PN coupler is complete
Repeat the configuration of the PN/PN coupler and PN/PN coupler slots for the other end
and ensure that you add the modules consistently to the other bus end.

4.2 Configuring the PN/PN coupler with STEP 7
Coupling both subnets
Once you have assigned one end of the PN/PN coupler with modules, STEP 7 provides a
help function which can be used to automatically assign the other end with suitable modules.
However, this requires that the two bus ends X1 and X2 be in the same project or in a
multiproject.
Example
In this example, we are assuming that the left end (X1) has already been assigned with
modules. To apply the "Coupling" function to the right-hand end (X2), proceed as follows:
1. Double-click the PN/PN coupler X2 symbol. The "Properties - PN/PN coupler" window
opens.
2. Switch to the "Coupling" tab and select:
– In a multiproject select the project for "Project" and the Ethernet subnet of the coupler
partner X1 for "Subnet"
– In a (standard) project, the Ethernet subnet of the coupler partner X1 for "Subnet"
3. Under "Device name", select bus node X1.
4. The "Configuration for:" field is assigned automatically depending on which bus end is
configured in the bus node.
5. Confirm your entries by clicking on "OK"
All modules in end X2 of the PN/PN coupler are now added to end X1, and the I/O type and
module lengths are specified. You can change the address areas of the modules without the
configuration becoming inconsistent. Bus end X2 is now also entered as a bus node in the
"Coupling" register of bus node X1.
If you have specified the two ends of a PN/PN coupler as bus nodes using the "Coupling"
function and you have a configuration between the two ends which is not consistent, an
incorrect configuration will be flagged up when you run the "Save and compile" function in
STEP 7.
Tip
We would recommend the following procedure if you make changes to a bus node:
1. Undertaking changes (e.g. adding I/O module)
2. Switch to bus node and in the "Coupling" register, click on "OK"
3. Run the "Save and compile" function for both stations
The configuration is thus always consistent.

Configuration of the PN/PN coupler with another configuring tool
Introduction
You configure the PN/PN coupler using a GSD file. Using this file, the PN/PN coupler is
incorporated in your configuring tool as an IO Device. The GSD files can be downloaded on
the Internet (http://support.automation.siemens.com/WW/view/en/23742537).
GSD file
The following GSD file is available for the PN/PN coupler:
GSDML-V2.25-Siemens-PNPNIOC-"Date in Format yyyymmdd".xml
You will find more information about this procedure in the online help for STEP 7.
Configuring the PN/PN coupler
You configure the PN/PN coupler with your configuring tool as you would for any other IO
Device with PROFINET IO.
To do this, load the entire GSD file for the PN/PN coupler into your configuring tool. You will
have to configure the PN/PN coupler separately in each of the two subnets. To do this,
select the device labeled as X1 or X2 (this does not apply to migration coupler).
When assigning device names for the PN/PN coupler, note the following: This device name
must be unique on the Ethernet subnet. The device name must satisfy the DNS conventions.
When configuring using a GSD file, you have a choice of input, output, or input/output
modules and modules for data record transfer, each of which have a fixed length. Assistance
to ensure the correct coupling configuration for the two subnets (as with STEP 7) is not
available when configuring a GSD file.

The parameters for the two ends of the PN/PN coupler can be set separately.
PS1 and PS2 are not assigned to one end and can be monitored separated on both ends.
Interrupts (e.g. when monitoring a power supply) are generated separately for each end.
The data validity display DIA may only be activated if inputs in the affected end of the PN/PN
coupler are configured (modules for data record transfer are not included in this).
Voltage check PS1 / PS2
Once voltage check PS1 / PS2 has been released, the PN/PN coupler diagnoses the power
supply failure at connection PS1 or PS2.
Only activate the voltage check if the corresponding power supply is actually connected.
Data validity display DIA
The data validity display DIA is used to establish whether the IO Controller connected via the
PN/PN coupler from the "other" subnet is still supplying valid data.
The data's validity is always shown in bit 0 of the lowest value input byte of the PN/PN
coupler:
Bit 0 = 1: received data are valid, all user data flags are "Good".
Bit 0 = 0. received data are invalid, at least one user data flag is "Bad".
Possible causes:
● an interface of the PN/PN coupler is damaged.
● The PN/PN coupler in the other subnet is not being powered.
● The PN/PN coupler in the other subnet is in STOP.
The lowest value input byte comes from the lowest slot number of the first input module.
CAUTION
Incorrect program intepretation
If "DIA" is activated, you must not use the first bit of the first configured input byte for input
data or the associated first bit of the first configured output byte in the other subnet for
output data!

Diagnostics data validity
With the data validity diagnosis you can establish whether the IO controller of the coupling
partner is in STOP status. The diagnosis is cancelled if the PN/PN coupler is transfering data
whose user data flag is on "Bad". The HW Config online diagnosis shows "data invalid" for
the respective slot.

Data record transfer from one IO Controller to another IO Controller
Introduction
The data record transfer via the PN/PN coupler, order no. 6ES7158-3AD01-0XA0 and
higher, enables acyclic data transfer (dataset transfer) up to 4096 bytes per slot from one IO
Controller (sender) to another IO Controller (receiver).
This acyclic dataset transfer enables you to exceed the cyclic I/O data transfer of 1024 byte
input and output (in sum).
Principle of operation
The modul types Storage und Publisher are available for the transfer of datasets. The
following figure shows the sequence of the transfer of a data record from one IO Controller to
another:

IO Controller 1 (sender) issues a send request to the PN/PN coupler and transfers the data
record to the PN/PN coupler.
The PN/PN coupler transfers the data record from its sender end to its receiver end.
The PN/PN coupler sends an acknowledgement to IO Controller 1 that the data record was
received.
The PN/PN coupler indicates to its receiver end that a data record is available to be read (via
status information of the PN/PN coupler and, optionally, via an update interrupt in IO Controller
2 (receiver)).
Only module type Storage: IO Controller 2 (receiver) reads the status information and the data
record and acknowledges the receipt.

Functions
5.1 Data record transfer from one IO Controller to another IO Controller
Boundary conditions for data record transfer
● Data record transfer does not correspond to data record routing.
● The I/O data (status information) are not coupled as a mirror image.
● The datasets are transferred in one direction, from the sender to the receiver.
● Both ends of the PN/PN coupler must exchange data with the connected IO Controllers. If
one end is not exchanging data and data for reading are already available, these data are
deleted when the end enters into data exchange. The dataset transfer starts when both
ends are exchanging data with the IO Controllers from a defined status.
Dataset transfer with the module type Storage
● The PN/PN coupler can buffer a maximum of 8 data records per slot, i.e., available for
reading. The buffer functions according to the first in - first out (FIFO) principle.
● If the receiver successfully read a dataset, he must then initiate the deletion of this
dataset from the buffer of the PN/PN coupler by explicit acknowledgment, so that the next
dataset can be read.
● If the sender attempts to write a dataset to the PN/PN coupler even though its buffer is
full, the PN/PN coupler rejects the dataset.
Dataset transfer with the module type Publisher
● The PN/PN coupler does not buffer datasets.
● The sender can only write datasets with the same "record index". This "record index" is
employed as parameter of the module on the sender side.
● If the sender delivers the next dataset, the previous dataset is overwritten.
● The PN/PN coupler shows the existence of a new dataset on the receiver side a
revolution counter.
● The receiver can read a dataset as often as he wants.
● If the receiver end does not know the length of the dataset, you must request the
maximum possible length of 4096 bytes in the read request to ensure that the entire data
record is read.

● Modul type Storage: "RD WRITE STO" on the sender side and "RD READ STO" on the
receiver side.
● Modul type Publisher: "RD WRITE PUB" on the sender side and "RD READ PUB" on the
receiver side.
The representation of the modules in the HW Config catalog is shown below:

Functions
5.1 Data record transfer from one IO Controller to another IO Controller
Update interrupt (OB 56)
Optionally, you can enable an update interrupt during parameterization of the "RD READ
STO" or "RD READ PUB" module that indicates to the receiver that a new data record is
available for reading in the buffer of the PN/PN coupler. The update interrupt is disabled by
default. A new update interrupt can only be issued when the preceding interrupt has been
acknowledged in the user program.
Note
On the module type Publisher the sender can overwrite the previous dataset if he wants to.
This does not guarantee that the receiver receives an update alarm for every dataset.
The update alarm has the alarm type 6. The update alarm uses the optional structure
element AlarmItem, which consists of:
● UserStructureIdentifier: 0x0050 (Unsigned16, ,manufacturer-specific),
● Data (to identify the dataset provided):
– RecordIndex (Unsigned16)
– RecordDataLength (Unsigned32) - for module type Storage
– Reserved (Unsigned32) - for module type Publisher
Example program for data record transfer
Below is a program example for dataset transfer from a sender (CPU 317-2 PN/DP) to a
receiver (CPU 317-2 PN/DP). The data are provided on the sender end for transfer in DB 12
and stored on the receiver end in DB 13.

5.2
Isochronous real-time communication
Isochronous real-time communication
Synchronized transmission method for the cyclic exchange of IRT data between PROFINET
devices. A reserved bandwidth is available within the send cycle for IRT IO data.
The reserved bandwidth ensures that IRT data can be transferred at reserved synchronized
intervals, without being influenced by other higher network loads (e.g., TCP/P
communication, or additional real-time communication).
PROFINET with IRT can be operated in the two options below:
● IRT option "high flexibility":
Maximum flexibility in planning and extending the system.
Topological configuration is not required.
● IRT option "high performance":
Topological configuration is required.
Note
IO controller as a sync master at IRT communication with the option "high performance"
We recommend also operating the IO controller as a Sync-Master if you configure the IRT
communication with the option "high performance". Otherwise, IRT and RT configured IO
devices may fail if the sync master fails.
Note
Configuring with maqximum Quantity Framework
When configuring a PN/PN coupler with maximum quantity framework of the I/O data the
maximum bandwidth for cyclic IO data is exceeded in the IRT communication with the
option "high performance" and an updating time of 250 µs.

Prioritized startup
Prioritized startup
Prioritized startup denotes PROFINET functionality for accelerating the startup of IO Devices
in a PROFINET IO system with RT and IRT communication.
The function reduces the time that the correspondingly configured IO Devices require in
order to return to the cyclic user data exchange in the following cases:
● After the power supply has returned
● After a station has come back online
● After IO Devices have been activated
Prioritized startup with PN/PN coupler
If you want to use the "Prioritized startup" function for the PN/PN coupler, you must set the
function on both ends of the coupler, X1 and X2.
Note
Firmware update
In prioritized startup it is not possible to perform a firmware update via Micro Memory Card.
Note
Startup times
The startup time depends on the number and type of modules.
Note
Prioritized startup and media redundancy
The inclusion of a IO device with prioritized startup in a ring topology with media redundancy
is not possible.
Cabling with fixed port setting
If you set a fixed connection setting of the port in STEP 7 (i.e.. no automatic settings), you
will also have to disable "Autonegotiation/Autocrossover."

Device replacement without removable medium/programming device
IO Devices having this function can be replaced simply:
● A removable medium (such as Micro Memory Card) with stored device name is not
required.
● The device name does not have to be assigned using the programming device.
Instead of being assigned a device name from the removable medium or programming
device, the IO Device is now assigned a device name by the IO Controller. The IO Controller
uses the configured topology for this purpose and the neighborhood relationships derived
from the IO Devices. The configured setpoint topology must agree with the actual topology.
Reset the IO devices, which were already in operation, back to the factory settings before
using them again.

5.5
SNMP
The PN/PN coupler supports the Ethernet service SNMP. LLDP-MIB and MIB-2 (RFC1213)
are supported. R/W objects can be changed using SNMP tools and are saved in the PN/PN
coupler. Each of the two bus ends (X1, X2) of the PN/PN coupler has its own memory area
for the SNMP data.
Following replacement with a brand new module, the R/W objects in the PN/PN coupler are
set to factory settings.

Shared Device
Shared Device
The feature "shared device" permits to split up the sub-modules of an IO device between
different IO controllers.
The IO controller and the Shared Device have to be located on the same Ethernet subnet
line so that the Shared Device function can be used.
The IO controllers are located in the same or in different STEP 7 project. If they are located
in the same STEP 7 project, a consistency test is automatically located.
PN/PN coupler as shared device
When configuring the PN/PN coupler as Shared Device the following conditions apply:
● Each slot can be allocated to only one IO controller (no shared input).
● The allocation of the slot of an IO device to the other IO device (coupling partner) must
happen 1 to 1 (e.g. slot 3 left coupling side > slot 3 on the right coupling side)
● The allocation of the slots of an IO device to an IO controller is preferable. No contiguous
slot area is required.
● One or two IO controllers can be configured on both bus ends.

Response times of the PN/PN coupler
Overview
This section covers the average time it takes to transfer data from the IO Controller (subnet
1) via the PN/PN coupler to the IO Controller (subnet 2).
Response times
The time between an IO Controller writing data in the outputs' process image and the time
when this data can be read in the process image of the second IO Controller depends on the
following parameters:
● CPU cycle time of the two IO Controllers
● Bus cycle time of the associated IO Controller
● Copy time within the PN/PN coupler (TCOPY)
● Total data length in bytes (input/output)
The copy time within the PN/PN coupler is not dependent on the data transfer rate used. It
consists of the copy routine for the inputs and for the outputs. The following maximum values
apply:
● Outputs: TCOPY = 44 µs + n x 0.2 µs
● Inputs: TCOPY = 68 µs + n x 0.4 µs (n = number of bytes)
The two times should be added together. Even with the maximum size of the data which can
be transferred (1024 byte input data / output data), the copy time is < 1 ms.
Influencing factors for the response times
The following applies to time-critical applications:
● Exchange as little data as possible via the PN/PN coupler.
● Do not start request of diagnostic data with the IO controller.
● Do not activate the data validity display DIA.
● Do not activate the data validity diagnosis.

6.2 SIMATIC Micro Memory Card
6.2
SIMATIC Micro Memory Card
Insertion of the SIMATIC Micro Memory Card
A SIMATIC Micro Memory Card is used as the memory medium for the PN/PN coupler.
Note
You can either save technology data (device names) or data for a firmware update on one
SIMATIC Micro Memory Card.
Note
Adopting the device name
If the PN/PN coupler already has a device name, then an empty SIMATIC Micro Memory
Card adopts the device name.
Service life of a SIMATIC Micro Memory Card
The life of an SIMATIC Micro Memory Card essentially depends on the following factors:
● Number of deletion or programming operations
● External factors, such as ambient temperature
At an ambient temperature up to 60 ° C a SIMATIC Micro Memory Card has a useful life of
10 years at maximum 100,000 write/delete sequences.
CAUTION
Possible data loss
If the maximum number of write/delete operations is exceeded, data loss is possible.
Applicable SIMATIC Micro Memory Cards
The following memory modules are available for use:
● A SIMATIC Micro Memory Card 64k is sufficient for storing the name of the device.
● The SIMATIC Micro Memory Cards with at least 2 MB of storage capacity are required
when conducting a firmware update.
The order numbers for the memory modules can be found in Appendix Order numbers and
accessories (Page 89).

Identification data
Definition
Identification data are information saved in a module which assist the user when:
● checking the plant configuration
● locating hardware changes on a plant
● remedying faults in a plant
Identification data enable modules to be uniquely identified online.
In STEP 7, the identification data are displayed in the registers "Module status - PN/PN
coupler" and "Properties– PN/PN coupler" (see online help for STEP 7).
Reading identification data
Each of the two bus ends (X1, X2) of the PN/PN coupler has its own memory area for the
identification data. You can enter or read out the identification data for each of the two bus
ends separately (does not pertain to I&M0).
You can access specific identification data using Read data record. You will find the
appropriate piece of identification data under the associated data record index.
The data records are structured using the following principle:

Description
● For I/O modules, the following applies:
If the IO Controller fails or the bus cable is removed, the PN/PN coupler supplies input
values to the other bus end featuring substitute value "0" and sets the user data flag to
"Bad".
● If the two bus ends of the PN/PN coupler do not have matching configuration, in the
dialog "Module status" of the last configured bus end, STEP 7 also supplies information in
hexadecimal code from which lowest slot number has the first deviation.
● For the modules "RD WRITE STO", "RD WRITE PUB", "RD READ STO" and
"RD READ PUB" the following applies:
If the IO Controller fails or the bus cable is removed, status information will continue to be
provided for the dataset transfer.
The user data flag remains at "Good".

7.2.2
Interrupts
The I/O device generates interrupts as a reaction to specific error events. Interrupts are
evaluated based on the I/O controller used.
The PN/PN coupler supports the following interrupts:
● Diagnostic interrupts
If there is communication between the IO Controller and PN/PN coupler, manufacturerspecific diagnostics of the PN/PN coupler are also active as interrupts which result in an
OB 82 being called up in a SIMATIC CPU.
● ReturnOfSubmodule interrupts
User data flags provide information about the validity of the IO data of a slot. If a user
data flag changes from "Bad" to "Good", a ReturnOfSubmodule interrupt is produced
which results in a OB 83 being called up within a SIMATIC-CPU.
The bus end of the PN/PN coupler which has already been configured produces a
ReturnOfSubmodule interrupt during configuration of the other bus end for each of the
matching slot in the configuration.
● Update alarm (OB 56) for modules "RD READ STO" and "RD READ PUB":
During parametrization of modules "RD READ STO" and "RD READ PUB" you can
optionally liberate an update alarm: This alarm indicates to the receiver that a new
dataset is available for reading in the buffer of the PN/PN coupler.
The update interrupt is disabled by default. A new update interrupt can only be issued
when the preceding interrupt has been acknowledged in the user program.
Note
Module "RD READ PUB"
During reception of new dataset in quick succession, it is not guarantee that the receiver
receives an update alarm for every dataset.
● Maintenance alarms
The PN/PN coupler supports the diagnostics and maintenance concept in PROFINET in
accordance with IEC 61158-6-10. The goal is early detection and correction of potential
faults.
For the PN/PN coupler, maintenance alarms signal to the the user when network
components must be checked or replaced.

Data validity display
Information covering all stations on the validity of the input data supplied by the other bus
end of the PN/PN coupler can be retrieved directly in the user program using the DIA
parameter (data validity display).
See also
Parameters (Page 34)
7.2.6
Evaluation of the useful data flag
Each IO module is assigned a value in the input or output data message; this value provides
a statement on the quality of this user datum. For example, outputs of a specific module can
be switched off by means of this without affecting other modules.
If inputs or outputs whose useful data flag is "Bad" are accessed, the corresponding CPU
calls up fault OB 85 or 122 (depending on whether the datum in question is in the process
image or the extended process image of the CPU).

● Diagnoses can be informed only to the IO controler that has a slot 0.
● The configuration-related diagnoses comprise all slots:
– The diagnosis "other network site not configured or malfunctioning" is genered if there
is a partner target slot for no individual target slot.
– The diagnosis "deviant configuration of subnets X1 and X2" is generated is there is a
difference relative to the module ID of the partner slot.
● The diagnosis "data validity DIA configured, but no input data configured" only comprises
the slots that have a slot 0 belonging to the IO controller.
● The diagnosis "data validity" comprises all use data flags, regardless of with which IO
controller the data are exchanged.

STOP of the IO controller and recovery of the IO device
IO controller stop
When in STOP mode, the IO controller supplies output data with a "Bad" useful data flag.
The PN/PN coupler indicates the STOP status of the IO controller of the other bus ends with
the optional diagnosis "data validity".
Diagnostics events triggered by a STOP of the IO controller
Diagnostics frames received from the IO device while the IO controller is in STOP mode will
not result in any the corresponding OBs being start once the IO controller starts up. You
have to produce yourself an image in OB 100 of the status of the IO device.
Diagnostics after recovery of the IO device
During recovery of an IO device, you must use SFB 52 to read data record E00CH. This
contains all the diagnostics data for the slots assigned to an IO controller in an IO device.

Glossary
Autonegotiation
Configuration protocol in Fast Ethernet. Before the actual data transfer, the devices on the
network agree on a transfer mode that each participating device can work with (100 Mbps or
10 Mbps, full-duplex or half-duplex).
Bus
A common transfer route connecting all nodes and having two defined ends.
Bus connector
A physical connection between the bus node and the bus line.
Data record routing
Forwarding of data records beyond subnet boundaries from a sender to receivers via a
router.
Device name
Before an IO Device can be addressed by an IO Controller, it must have a device name. This
procedure was selected for PROFINET because names are easier to handle than complex
IP addresses.
Assignment of a device name for a specific IO Device can be compared with the setting of
the PROFIBUS address for a DP slave.
An IO Device does not have a device name upon delivery. Only once a device name has
been assigned using the PG/PC, can an IO Device be addressed by an IO Controller, e.g.
for the transmission of configuring data (including the IP address) during start-up or for the
exchange of useful data in cyclic mode.
Device replacement without removable medium/programming device
IO Devices having this function can be replaced simply:
● A removable medium (such as Micro Memory Card) with the stored device name is not
required.
● The device name does not have to be assigned using the programming device.
The replaced IO Device receives the device name from the IO Controller, not from the
removable medium or from the programming device. For this purpose, the IO Controller uses
the configured topology and the neighborhood relationships determined by the IO Devices.
The configured setpoint topology must agree with the actual topology.

Glossary
Diagnostics
Diagnostics is the detection, localization, classification, display and further evaluation of
errors, faults, and messages.
Diagnostics provides monitoring functions that run automatically while the system is in
operation. This increases the availability of systems by reducing setup times and downtimes.
Earth
The conductive earth whose electric potential can be set to zero at any point.
Electromagnetic compatibility (EMC)
Electromagnetic compatibility is understood as the ability of a piece of electrical equipment to
function perfectly in a specified environment without impacting on its surroundings in an
impermissible way.
Equipment, electrical
All components, power circuits or parts of power circuits that are normally to be found in one
single enclosure.
Equipotential bonding
Electrical connection (equipotential bonding conductor) that brings the conductive parts of
electrical equipment and other conductive parts to the same or approximately the same
potential in order to prevent troublesome or dangerous voltages arising between these parts.
External lightning protection
External plant components at which galvanic coupling of lightning surges is excluded.
Corresponds with lightning protection zone 0A and 0B.
Fast Ethernet
Fast Ethernet describes the standard for transmitting data at 100 Mbps. This transfer
technology uses the 100 Base-T standard for this.
Firmware update
Updating of firmware of interface module
After (compatible) function extensions or after improvements to performance, the interface
module can be updated to the latest firmware version.
Ground
The ground refers to all the interconnected inactive parts of a piece of equipment that, even
in the event of a fault, cannot pick up voltage that is dangerous to touch.

Installation and Operating Manual, 06/2010, A5E00717043-04
Glossary
Grounding
Grounding means connecting an electrically conductive part to a grounding system by
means of the ground electrode.
GSD file
The properties of a PROFINET device are described in a GSD file (General Station
Descriptor), which contains all the information required for configuration.
As with PROFIBUS, you can link a PROFINET device in STEP 7 by means of a GSD file.
In PROFINET IO, the GSD file is always in XML format. The structure of the GSD file
corresponds to ISO 15734, the worldwide standard for device descriptions.
HW configuration
Part of STEP 7 for configuring hardware.
Industrial Ethernet
Industrial Ethernet (previously SINEC H1) is a technology that allows data to be transferred
without interference in an industrial environment.
Due to the openness of PROFINET, you can use standard Ethernet components. We
recommend, however, that you install PROFINET as Industrial Ethernet.
Isochronous real-time communication
Synchronized transmission method for the cyclic exchange of IRT data between PROFINET
devices.
A reserved bandwidth is available within the send cycle for IRT IO data. The reserved
bandwidth guarantees that IRT data can also be transferred at reserved, synchronized
intervals while other, higher network loads are active (for example, TCP/IP communication,
or additional real-time communication).
LAN
Local Area Network; interconnects multiple computers within a company. The geographical
topology of a LAN is limited to the local premises and is only available to the operating
company or institution.
LLDP
LLDP (Link Layer Discovery Protocol) is a protocol that is used to detect the closest
neighbors. It enables a device to send information about itself and to save information
received from neighboring devices in the LLDP MIB. This information can be looked up via
the SNMP. This information allows a network management system to determine the network
topology.

Glossary
MAC address
Each PROFINET device is assigned a worldwide unique device identifier in the factory. This
6-byte long device identifier is the MAC address.
The MAC address consists of:
● 3-byte manufacturer ID and
● 3-byte device ID (sequential number).
The MAC address is placed legibly on the front of the device
e.g.: 08-00-06-6B-80-C0
Parameterization
The term parameterization denotes the transfer of parameters from the IO Controller to the
IO Device.
PELV
Protective Extra Low Voltage = extra low voltage with safe isolation
Power supply unit
A power supply unit supplies power to the field devices and the distributed process I/Os
connected to them.
Prioritized startup
Prioritized startup denotes PROFINET functionality for accelerating the startup of IO Devices
in a PROFINET IO system with RT and IRT communication. The function reduces the time
that the correspondingly configured IO Devices require in order to return to the cyclic user
data exchange in the following cases:
● After the supply voltage has returned
● After a station has returned
● After IO Devices have been activated
Process image
The process image is part of the IO Controller's system memory. The signal states of the
input modules are transferred to the process-image inputs at the beginning of the cyclic
program. At the end of the cyclic program, the process image of the outputs is transferred to
the IO Controller as signal status.

PROFINET
Within the context of Totally Integrated Automation (TIA), PROFINET is the systematic
continuation of the following systems:
● PROFIBUS DP, the established fieldbus
● Industrial Ethernet, the communication bus for the cell level
Experiences from both systems have been and are being integrated in PROFINET.
PROFINET is an Ethernet-based automation standard of PROFIBUS International
(previously PROFIBUS User Organization e.V.), and defines a multi-vendor communication,
automation, and engineering model. PROFINET has been part of IEC 61158 since 2003.
See PROFIBUS International
PROFINET components
A PROFINET component includes all data of the hardware configuration, the parameters of
the modules, and the associated user program. The PROFINET component comprises the
following elements:
● Technological function
The (optional) technological (software) function includes the interface to other PROFINET
components as interconnectable inputs and outputs.
● Device
The device represents the physical automation device or field device, including the IO,
sensors and actuators, mechanical system, and device firmware.
PROFINET device
A PROFINET device always has at least one Industrial Ethernet port. Additionally, a
PROFINET device can have a PROFIBUS connection: as master with proxy functions In
exceptions, a PROFINET device can also have a several PROFIBUS connections (for
example CP 5614).
PROFINET IO Controller
Device by means of which connected IO Devices are addressed. In other words: The IO
Controller exchanges input and output signals with the assigned field devices. The IO
Controller is often the controller in which the automation program is executed.

PROFINET IO
Within the context of PROFINET, PROFINET IO is a communication concept for
implementing modular, distributed applications.
PROFINET IO allows you to create automation solutions familiar from PROFIBUS.
Implementation of PROFINET IO is carried out on the one hand via the PROFINET standard
for automation devices and on the other by using the engineering tool STEP 7.
This means that you have the same application layer in STEP 7 – regardless of whether you
configure PROFINET devices or PROFIBUS devices The programming of your user program
is identical for PROFINET IO and PROFIBUS DP when you use the blocks and system
status lists expanded for PROFINET IO.
PROFINET IO Device
Distributed field device which is assigned to one of the IO Controllers
(e.g. remote IO, valve terminals, frequency converter, switches).
Reference potential
Potential that is used to view and/or measure voltages for each circuit involved.
SELV
Safety extra low voltage (SELV) is voltage ≤ 30 V AC/60 V DC that is generated via a safety
transformer or accumulator.
SNMP
SNMP (Simple Network Management Protocol) is the standardized protocol, for diagnosing
and also configuring the Ethernet network infrastructure.
In the office setting and in automation engineering, devices from many different
manufacturers support SNMP on the Ethernet.
SNMP-based applications can be operated on the same network in parallel to applications
with PROFINET.
The scope of the supported functions differs depending on the device type. For example, a
switch has more functions than a CP 1616.

Switch
PROFIBUS is a linear network. The communication nodes are connected with one another
by means of a passive line - the bus.
By contrast, the Industrial Ethernet consists of point-to-point connections: each
communication node is directly connected to exactly one communication node.
If a communication node is connected with several communication nodes, this
communication node is connected to the port of an active network component - the switch.
Additional communication nodes (including switches) can now be connected to the other
ports of the switch. The connection between a communication node and the switch remains
a point-to-point connection.
A switch also has the task of regenerating and distributing received signals. The switch
"learns" the Ethernet address(es) of a connected PROFINET device or other switches and
only forwards signals, which are destined for the connected PROFINET device or the
connected switch.
A switch has a specific number of ports. You connect at most one PROFINET device or
additional switch to each port.
TN-S system
In a TN-S system, the neutral conductor (N) and protective conductor (PE) are wire with
separate insulation. The neutral conductor is connected to the grounded protective
conductor at a central point, and only there. The protective conductor can be grounded any
number of times.
Transmission rate
The transmission rate specifies the number of bits transmitted per second.
ungrounded
Having no conductive connection to earth
User data flag
Each IO module is assigned a value in the input or output data message; this value provides
a statement on the quality of this user datum. For example, outputs of a specific module can
be switched off by means of this without affecting other modules.
