Properties and Services
Properties and Services
Application
The IWLAN/PB Link PN IO is a gateway that connects the Industrial Wireless LAN
(control level) and PROFIBUS (cell/field level) networks to each other.
SCALANCE W78x
The IWLAN/PB Link PN IO supports access to all PROFIBUS DP slaves on the
subordinate PROFIBUS; DP slaves complying with PROFIBUS DP-V0 are
supported and, as of firmware version V1.1.0, also DP slaves complying with the
DP-V1 standard and Siemens DP slaves.
The Industrial Wireless LAN (IWLAN) with RCoax and WLAN antenna for wireless
or non-contact data transmission is ideal for a variety of mobile applications,
including monorail conveyors and high-bay storage and retrieval systems.
The IWLAN/PB Link PN IO can be operated in the following modes:
S
Gateway as PROFINET IO proxy
S
Gateway in standard operation

Properties and Services
Gateway as PROFINET IO proxy
The IWLAN/PB Link PN IO is a key component of PROFINET IO. It is
responsible for the connection between the PROFINET IO controllers on
Industrial Ethernet and the PROFINET IO devices (DP slaves on PROFIBUS).
From the point of view of the PROFINET IO controller on Industrial Ethernet,
the process of accessing PROFINET IO devices that are connected to
Industrial Ethernet via the Industrial Wireless LAN and IWLAN/PB Link PN IO
and accessing PROFIBUS DP slaves that are connected to PROFIBUS DP is
identical.
The IWLAN/PB Link PN IO acts as a proxy for the DP slaves connected to
PROFIBUS DP.

Properties and Services
Gateway in standard operation
The following services are available in standard operation:
S
PG/OP communication
PG/OP communication is used to download programs and configuration data,
run test and diagnostic functions, as well as operate and monitor the plant (HMI
systems).
S
Assigning parameters to field devices (data record routing)
You can use the IWLAN/PB Link PN IO as a router for data records that are
addressed to field devices (DP slaves). In this way, devices that are not directly
connected to PROFIBUS and, therefore, cannot access the field devices (DP
slaves) directly, can transmit data records to the field devices via the
IWLAN/PB Link PN IO.
The SIMATIC PDM (Process Device Manager) is an example of a tool that
creates data records for assigning parameters to field devices.
S
Gateway to a DP master system with constant bus cycle time
The IWLAN/PB Link PN IO acts as a gateway between the Industrial Wireless
LAN and the field devices on a DP master system. The IWLAN/PB Link PN IO
is used here as an active node along with a DP master on a PROFIBUS that
has been set to constant bus cycle time.
S
Cross-subnet S7 connections for HMI operation
The IWLAN/PB Link PN IO forwards communication via S7 connections. This
service is used for HMI applications (PC stations), for example.

Properties and Services
Gateway in mobile applications
The IWLAN/PB Link PN IO enables wireless communication with programmable
controllers in mobile applications, such as automated guided vehicle systems,
high-bay storage and retrieval systems, and monorail conveyors. Solutions
involving power rail boosters for PROFIBUS via slip contacts can, therefore, be
replaced with a non-contact, non-wearing data transmission technology.
It can be connected via a WLAN antenna or an antenna for use with an RCoax
cable (leak-mode conductor).
Industrial Ethernet
Gateway in PROFINET IO applications with iPCF (industrial Point Coordination
Function)
The IWLAN/PB Link PN IO supports iPCF mode.
The use of iPCF is recommended particularly when a high throughput is required
with large numbers of nodes or when very short handover times are necessary.
The iPCF mechanism was further optimized for operation with PROFINET IO data
traffic by handling PROFINET IO data traffic with high priority.

Properties and Services
Notice
For PROFINET IO communication, we recommend enabling the iPCF mode.
Stable PNIO communication is only possible when it is guaranteed that a WLAN
client is in a cell with more than 60% signal strength at all times. This can be
checked by activating and deactivating the various segments.
This does not mean that the client needs to change when there is a signal strength
less than 60%. It is only necessary to make sure that a segment with adequate
signal strength would be available.

Configuring the PRESET PLUG
Overview
The PRESET PLUG is a simple device for assigning a defined default setting to an
IWLAN/PB Link PN IO and SCALANCE W devices.
The PRESET PLUG is first configured in a SCALANCE W788 with the required
WLAN parameters and then inserted in the C-PLUG slot on the target system for
commissioning purposes.
When several WLAN clients with the same parameters are used, the advantage of
this procedure is that you do not have to assign parameters to each individual
client manually.
If a PRESET PLUG is not used in your application, proceed as described in
Section 3.4.
Notice
The PRESET PLUG 6GK5798-8AB00 is only used for commissioning purposes.
The device cannot be operated with the WLAN when the PRESET PLUG is inserted.
Configuring the PRESET PLUG
To configure a PRESET PLUG, you require a device of the type SCALANCE W7xx
with a firmware version V3.0 or higher.
You can use this procedure to configure a PRESET PLUG from scratch or to
change an existing configuration.
Follow the steps below:
Step
Procedure
1.
Insert a new PRESET PLUG or one that has already been configured into the
C -PLUG slot on the SCALANCE W7xx, which must be switched off.
2.
Switch the device on.
3.
Open the Web interface for the SCALANCE W7xx.
The Web interface displays the current settings for the PRESET PLUG
(provided a configuration already exists).

Via PROFIBUS (for standard operation only)
Industrial Ethernet and WLAN interface (recommended)
Commissioning the device for the WLAN is described in detail in this chapter (3).
When configuring on the PG, a distinction must be made between the following
modes:
S
PROFINET IO use case
In this use case, the IWLAN/PB Link PN IO obtains its project engineering data
from the controller. This means:
- Controller and Link must be connected over the WLAN;
- The Link must already have been assigned a device name with STEP 7 so
that the project engineering data can be downloaded.
Read the detailed description of project engineering in Section 4.1.
S
Standalone Mode
In this use case, the IWLAN/PB Link PN IO is configured and downloaded as
an S7-300 station. This can take place as soon as you have assigned an
Ethernet address to the device with STEP 7. Read the detailed description of
project engineering in Section 4.2.
PROFIBUS (for standard operation only)
The IWLAN/PB Link PN IO can be reached over the PROFIBUS interface. You
must, however, first assign a PROFIBUS address in the project engineering.

Installation and Commissioning
Power Supply
Warning
The IWLAN/PB Link PN IO is designed for operation with safety extra-low voltage
(SELV). This means that only safety extra-low voltages (SELV) complying with
IEC950/EN60950/ VDE0805 may be connected to the power supply terminals.
The power supply unit to supply the IWLAN/PB Link PN IO must comply with NEC
Class 2 (voltage range 20.4 - 28.8 V, current requirement 300 mA).
The device must only be supplied by a power supply unit that complies with the
requirements of class 2 for power supply units of the ”National Electrical Code,
Table 11 (b)”. If the power supply is installed redundantly (two separate power
supplies), the total power of both power supplies together must meet these
requirements.
Exceptions:
S Supply by a SELV power source (complying with IEC 60950) or PELV power
source (complying with VDE 0100-410) without restricted power is also
permitted as long as suitable fire prevention measures are taken by means of:
- installation in cabinet or suitable enclosure
- installation in suitably equipped, closed room
The power supply is connected over a 4-pin plug-in terminal block. The power
supply can be connected redundantly. The two inputs are isolated. There is no load
sharing. When the supply is redundant, the power source with the higher output
voltage supplies the IWLAN/PB Link PN IO alone. The power supply is connected
to the housing over a high resistance to allow ungrounded installation.

C-PLUG (Configuration Plug)
C-PLUG removable memory medium as an alternative to flash memory
The IWLAN/PB Link PN IO has an internal flash memory for storing the project
engineering data. As an option, the device can be operated with a C-PLUG
(configuration plug) removable memory medium.
The IWLAN/PB Link PN IO can be operated with or without a C-PLUG. The
existing flash memory is then only used when no C-PLUG is inserted.
If a C-PLUG is inserted, the project engineering data is always stored on it. This
simplifies replacement of modules. By simply exchanging the C-PLUG, all the data
can be transferred to the replacement module.
Response to an unknown or invalid C - PLUG
If a C-PLUG is inserted that does not have the correct format or valid data for the
IWLAN/PB Link PN IO, the IWLAN/PB Link PN IO will not start up. Device status:
System fault LED lit.
To ensure that you can access the IWLAN/PB Link PN IO via the WLAN interface
in this status, the WLAN parameters stored in the internal flash memory are used.
If you know this parameter, please format the C-PLUG with NCM diagnostics or
replace the C-PLUG with a C-PLUG with valid data.
If, however, you do not know this parameter and cannot establish a connection in
the WLAN, use the RESET button to run a ”reset to factory settings” with the
C-PLUG inserted (see Section 5.2); you then operate with the default WLAN
parameters.
Notice
The C-PLUG may only be inserted or removed when the power is turned off!

Use as a PROFINET IO Device and as a Gateway
For this application, configure the IWLAN/PB Link PN IO as a PROFINET IO
device with STEP 7/HW Config and assign a DP master system to the
IWLAN/PB Link PN IO.
Load the configuration data to the PROFINET IO controller, which then
automatically loads it to the IWLAN/PB Link PN IO.
Notice
You must always restore the factory settings when you switch the configured IWLAN/PB Link PN IO operating mode. The device can only be operated as a PROFINET IO device or as a gateway.
4.1.1
Configuring the Properties with STEP 7
To assign address information and further parameters to the
IWLAN/PB Link PN IO, you have to generate a loadable database (configuration)
in STEP 7.
Follow the steps below
Step
Configuring the IWLAN/PB Link PN IO as a PROFINET IO device with
STEP 7/HW Config
1.
Use an existing STEP 7 project in which you have already created a PROFINET IO
controller (e.g. an S7-400 station with a CP 443-1 Advanced).
2.
Open HW Config by double-clicking the station you created .
3.
Take the device type gateway IWLAN/PB Link PN IO from the hardware catalog under
PROFINET IO and add this as an IO device on the PN IO system of the IO controller.
An IP address for the PROFINET IO system interface is determined automatically here.
STEP 7 also assigns a device number to the IWLAN/PB Link PN IO. It chooses the highest
free device number in the current PROFINET IO system.
Step
4.
Connecting the PROFIBUS subnet in the STEP 7 project
Once you have transferred the IWLAN/PB Link PN IO from the hardware catalog, you are
prompted to network the IWLAN/PB Link PN IO to the PROFIBUS interface.
If you have not yet created the required subnets, you can do this now by selecting the
relevant entry. This creates a DP master system.
Results:
In HWConfig, the IWLAN/PB Link PN IO is created as a PROFINET IO device with a DP master system.

Update Time for the PROFINET IO System
You can display and set the parameters described below in the properties dialog
box for the PROFINET IO system in HW Config.
Setting the update time
Update times can only be set in certain intervals. STEP 7 determines the relevant
values on the basis of the properties of the IO devices involved.
If you change the basic hardware configuration, for example, add new IO devices,
the update time can change. The next time you open the dialog, a message
informs you that the update time has changed.
The default value for the update time is calculated automatically depending on the
maximum number of links on an IWLAN segment (or AP).
Notice
Note that the update time you choose for the SCALANCE W788-RR must be identical to the setting described here for the IWLAN/PB Link PN IO in the STEP 7
configuration.
Set the update time over the CLI in the following menu: “ifeature " ipcf " PN IO
Update Time
Selection of channels to be scanned
The minimum selectable update time is decided by the number of WLAN clients on
an access point in the configuration in STEP 7.
To keep the proportion of cycle time required for scanning channels to a minimum
when roaming, we recommend that you use the “Background scan channels”
setting. This restricts the number of channels on which the IWLAN/PB Link PN IO
scans for a channel.
To use this, select the following settings in the “Interfaces " wlan1 " Advanced”
menu:
S
Background scan channel select -> activates the background scan
S
Background scan channels -> selection of channels to be scanned
This optimizes the roaming characteristics in terms of time.

Configuration with STEP 7
Optimizing the update time
You can optimize the update time by specifying the maximum number of links in
your system on the ”IWLAN Parameters” tab.
Notice
If the update time you choose is too short or if the IWLAN segment has more links
than you specified on the ”IWLAN Parameters” tab, this may cause the connection
to be interrupted. For this reason, you are advised to retain the default settings.
When optimizing the update time, you must take into account the following points
to ensure stable communication:
S
Case a: your system is operated in a single wireless segment; in other words,
the clients (IWLAN/PB links, SCALANCE W74x) do not need to support
roaming to another wireless segment.
In this case, update times of >=8 ms are supported.
Optimum wireless conditions without roaming: update times of 4 ms are only
possible under optimum wireless conditions and when the cell has just one
client.
S
Case b: your system is operated with two wireless segments on two different
channels.
In this case, update times of >=16 ms are also supported.
S
Case c: your system is operated with more than one wireless segment and
more than two channels. The clients also switch between the segments (roam).
In this case, the PN IO update time should be higher than 16 ms.
Notice
You are strongly advised to check the local radio conditions before commissioning.

4.1.3
Assigning Device Names and Downloading the Configuration
The IWLAN/PB Link PN IO is supplied with a fixed MAC address. Without further
configuration, the device can only be accessed over the WLAN port using this
MAC address.
An IP address is automatically assigned during configuration. Later when the
PROFINET IO controller is started up, this IP address is transferred to the
IWLAN/PB Link PN IO (IO device).
To ensure that the IO controller can identify the IO device during this procedure,
you first have to assign a device name to the IWLAN/PB Link PN IO as you do to
every other IO device. You only have to assign the name once.
Follow the steps below
Step
1.
Procedure
Assign a device name to the IWLAN/PB Link PN IO (you only have to do this once).
You can do this in the SIMATIC Manager or in HW Config with the menu command
PLC " Ethernet " Assign device name...
(More detailed information on this procedure is available in the STEP 7 online help.)
2.
Load the configuration for the associated PROFINET IO controller.
The IO controller receives the configuration data from the IWLAN/PB Link PN IO. When the
IO controller is started up, the IWLAN/PB Link PN IO and all the other PROFINET IO
devices are configured automatically.
Note
The configuration data loaded by the PROFINET IO controller is not stored
retentively by the IWLAN/PB Link PN IO. When you switch the device off and then
on again, all the configuration data except for the device name is deleted. During
startup, the configuration data is reloaded by the PROFINET IO controller.

Features of Data Record Routing
Assigning parameters to field devices (data record routing)
You can use the IWLAN/PB Link PN IO as a router for data records that are
addressed to field devices (DP slaves). In this way, devices that are not directly
connected to PROFIBUS and, therefore, cannot access the field devices (DP
slaves) directly, can transmit data records to the field devices via the
IWLAN/PB Link PN IO.
The SIMATIC PDM (Process Device Manager) is an example of a tool that creates
data records for assigning parameters to field devices.
The function is activated by default.

Compatibility with Predecessor Products
Compatibility with Predecessor Products
Use as a replacement:
Changing to hardware version AS 03
As of hardware version AS 03, the IWLAN/PB Link PN IO uses a new IWLAN
wireless module with modified wireless properties compared with the IWLAN
wireless modules of hardware versions AS 01 and AS 02.
When converting to devices as of hardware version AS 03, the previous
configuration on C-PLUG, Preset Plug and in the configuration file “config.cfg” can
be used in most cases.
When adopting a configuration, created with a hardware version lower than AS 03,
remember the following:
S
The displayed parameter for the transmit power is adapted automatically
without resulting in changes to the transmit power.
Example:
At the setting “Half, 1/2 (-3dBm)”, a device with hardware version AS 03 has a
maximum transmit power of 17 dBm.
A device with a hardware version less than AS 03 also has a maximum transmit
power of 17 dBm if the “Transmit Power” parameter is set to “Full (-0dB)”.
The parameters for other transmit power settings are also adapted
automatically.
S
The antenna type is automatically set to the value “User Defined”.
The value set for the antenna gain parameter is adopted.
Example:
The value “ANT795-6MR, 5m cable” is automatically converted to
“User defined” with the appropriate antenna gain.
Note
The adaptation/transfer of the parameters is handled by the new device
automatically when it is restarted after adopting the old configuration.
There are, however, configurations in which the adaptation of the parameters
cannot be handled by the firmware. In these cases, you will need to adapt the
configuration manually.

Compatibility with Predecessor Products
S
When selecting channels in frequency bands with different limit values for
transmit power, it is possible that the list of selectable channels is restricted due
to the different wireless properties.
This may mean that devices can no longer be reached via the wireless
interface!
When replacing devices with the previous versions with devices with
hardware version AS 03, we therefore strongly recommend that these are
checked in a test environment to make sure that they adopt the channel
selection unchanged.
The channel selection is, for example dependent on the set transmit power and
can be influenced by modifications to the relevant parameters.
Once a device with hardware version AS 03 has been assigned parameters
with a configuration file from an older device, all the parameters relating to
national approvals are checked.
Note
During a transitional period, it is possible that some national approvals are not yet
available for the devices with hardware version AS 03 because the certification
process takes longer in some countries.
You should therefore make sure that the devices are approved for your application
by checking the following Internet page:

Further notes regarding operation
Changing interface parameters during download
If you change the interface parameters that are already set (e.g. the transmission
speed), this can cause the download process to be aborted.
In this case, adjust the PG/PC interface and network configuration in line with the
new interface parameters and carry out the download again.
9.2
Time forwarding
If the time forwarding function in the IWLAN/PB Link PN IO is deactivated, the
device uses the internal time, even if the Ethernet has a time master.
9.3
SNMP agent
SNMP (Simple Network Management Protocol)
The IWLAN/PB Link PN IO supports data querying via SNMP in version 1.
SNMP is a simple protocol language for managing networks. For data
transmission, SNMP is based on the connectionless protocol UDP.
Information about the properties of SNMP-capable devices is available in ”MIB”
files (MIB = Managed Information Base). For more detailed information about using
MIB files, see the documentation provided with the SNMP clients used (example of
an SNMP client: SNMP OPC server of SIMATIC NET).

Supported MIBs
The IWLAN/PB Link PN IO supports all MIB objects in the standard MIB (in
accordance with MIB II (RFC 1213)).
Exceptions / restrictions:
S
Write access is enabled for the following MIB objects only:
sysContact, sysLocation, and sysName
In all other cases, only read access is enabled (for security reasons).
Access rights via community name
The IWLAN/PB Link PN IO uses the following community names to assign rights:
S
Read access: ”public”
S
Read/write access: ”private”
(Note use of lower case!)
Evaluating traps
To evaluate the IWLAN/PB Link PN IO traps, you need the appropriate private MIB
file for this device. The private MIB files contain the device and
manufacturer -specific MIB objects.
The private MIB file for the IWLAN/PB Link PN IO is in the SCALANCE W7xx type
devices. You can download them from there and import them to your trap receiver.
To do so, enter the following URL in your Web browser:

How to Load New Firmware
How to Load New Firmware
Requirements
S
When downloading over PROFIBUS
- There must be a PROFIBUS CP module in the PG/PC.
S
When downloading over Industrial Ethernet
- To download firmware, you require an Industrial Ethernet CP module in the
PG/PC (for example, CP 1613) or a normal Ethernet module with the
“Softnet” software package.
- The S7-ONLINE interface must be set to the “ISO - Industrial Ethernet”
protocol. It is not possible to download using TCP/IP (and therefore not to
other networks).
How to Download New Firmware
You download new firmware to a SIMATIC NET CP using the firmware loader
shipped with STEP 7 / NCM S7 for Industrial Ethernet and PROFIBUS.
S
Start the firmware loader and follow the instructions step-by-step.
What to do if a Download is Interrupted
Disturbances or collisions on the network can lead to packets being lost. In such
cases, this can lead to an interruption of the firmware download. The firmware
loader then signals a timeout or negative response from the module being loaded.
If you were unable to download the new firmware successfully, (download over
IWLAN or PROFIBUS), you should run the download again directly over
PROFIBUS.
If the device is not ready to accept the download, follow the steps below:
1. Turn off the power supply to the IWLAN/PB-Link
2. Press the Reset button and keep it depressed. Turn the power supply on again
and wait until the SF-LED flashes.
3. Release the Reset button again; the device is now ready for the firmware
update over PROFIBUS using the firmware loader.
