2.2.1 Network Management
The WirelessHART Gateway contains a network manager. The network manager takes
care of the wireless communication between the WirelessHART field devices. The network
manager takes care of the creation and maintenance of the wireless mesh network to
ensure proper communication between the WirelessHART field devices.
Figure 2.2Network management
1 Step 1: Advertising
2 Step 2: Joining
3 Step 3: Scheduling
4 WirelessHART Gateway
5 WirelessHART field device
First, the network manager sends advertising messages to announce the network’s
existence. When a WirelessHART field device receives such an advertising message, it
tries to join the network. If the WirelessHART field device can identify itself with the same
network ID and join key as stored in the WirelessHART Gateway, the field device is allowed
to join the network. Otherwise, the field device will be rejected.
The network manager can also instruct already joined devices to advertise on its behalf.
221981 2011-07
12
WHA-GW-*
Product Specifications
In the next step, the network manager sends scheduling information to the field device. The
field device is told how to participate in the network and receives various information from
the WirelessHART Gateway:
• Number and identity of neighboring WirelessHART field devices,
• When to send messages and which channels to use,
• When to repeat messages for other WirelessHART field devices,
• The optimal communication path for messages as well as alternative communication
paths in case of failure.
During this process, the field device may also apply to send messages in certain intervals
and ask the network manager for the appropriate resources. The network manager then
takes care that these resources are available. For example, the network manager informs
other WirelessHART field devices when to repeat messages.
2.2.2 Security Management
The security manager is part of the WirelessHART Gateway. To make communication safe,
all messages are encrypted with industry-standard AES-128 block ciphers with symmetric
keys. Therefore, messages are unreadable for external listeners.
The security manager distributes the encryption keys and changes them in certain
(random) intervals, as an option.
2.2.3 Virtual Remote I/O system
The WirelessHART Gateway make wireless communication accessible to HOST systems
capable of HART technology through the following principles.
Instrument List
WirelessHART devices and wired devices connected to a WirelessHART adapter are made
available to HOST systems via a virtual HART I/O system. This I/O system contains one or
multiple I/O cards. Each I/O card has up to 2 channels. To each channel, up to 6 wired field
devices may be connected in multi-drop mode. (see Figure 2.3 on page 14).
The P+F WirelessHART Gateway assigns a virtual I/O card to each WirelessHART device
and stores card and channel values in the Instrument List. The I/O cards are assigned to
the WirelessHART devices in chronological order (0 ... 249). New WirelessHART devices in
the network are assigned to the next available I/O card.
WirelessHART devices are always assigned to Channel 0 of an I/O card. All wired devices
connected to a WirelessHART adapter are always assigned to channel 1 of the same I/O
card as the adapter (multi-drop mode).

4 WirelessHART adapter (joined second): I/O card 1, channel 0
5 Wired devices 1...3 connected to WirelessHART adapter: I/O card 1, channel 1
If a WirelessHART device loses communication to the Gateway, it keeps its position in the
Gateway's Instrument List and stays assigned to the respective I/O card. When
communication is established again, the device has the same channel/card values that it
had before.
The same principle applies to the field devices connected to the WirelessHART adapter:
After communication to the Gateway was lost, the field devices regain their previous
position in the Instrument List as soon as communication is established again.
Note!
The Instrument List is stored in a non-volatile memory. Card/channel number assignment
will remain the same after a Gateway power-up or software restart.

Product Specifications
Long Tag Emulation
The WirelessHART communication protocol uses the long tag to address devices.
However, long tags are only supported by HART 6 devices and newer devices
(HART 6 = version 6 of the HART communication protocol; current version: HART 7). Older
devices, for example HART 5 devices, have to be addressed by the "Message" field. If a
HART 5 device is connected to the WirelessHART network using a WirelessHART adapter,
the WirelessHART Gateway emulates the long tag with the "Message" field.
2.2.4 Gateway Cache Management
The WirelessHART Gateway caches parameters and dynamic values of the wireless and
wired subdevices and makes them available to the HOST. Some commands are cached by
the Gateway automatically (upon read). Other commands, for example dynamic values, are
only cached if the respective field device publishes them (upon publishing). For more
information on publishing of device values prease refer to the Burst lists section (see
chapter 5.4.3).
The responses to the command requests listed in the following table are cached in the
Gateway. Commands in the same row have an identical response frame and share the
same cache memory. The write commands (17, 18, 22, 51) will never get an immediate
answer, but their response will be cached (caching upon write-confirmation).

3.1 Mounting Considerations
3.1.1 Positioning the Gateway
Install the Gateway first, before installing other WirelessHART devices. This way you can
check for proper operation of new devices as they are installed. Nevertheless, consider the
location of future WirelessHART devices that will be routed through the Gateway to ensure
good connectivity.
Guidelines for Planning a WirelessHART Network
• A line-of-sight between communication partners always is desirable. If a line-of-sight is
not possible, the obstacles should not be massive and the partners should be more to
the edge of an obstacle to allow the wave to "bend" around it (diffraction effect).
• Consider moving objects that could affect the device's antenna range.
• Install wireless devices at least 1 m above the ground or the floor.
• Make sure that the device's antenna is aligned vertically for best results.
• Make sure that a minimum of 2 other WirelessHART devices are well within the antenna
range of the device (see chapter 9). For more information on the antenna
characteristics please refer to the following section.
• Do not position WirelessHART devices directly below or above each other. They would
be outside each other's antenna range.
• Install WirelessHART devices at least 1 m away from each other.
• Antennas must be at least 6 cm away from any wall or any metallic material running
parallel to it.
• Position the device as far away as possible from metal surfaces or walls containing
metal. There should be as little metal close to the device as possible.
• Do not position other 2.4 GHz devices like cordless phone bases or WLAN routers near
WirelessHART devices. Keep in mind other wireless networks using the same
frequency spectrum (WLAN, Bluetooth, etc.). Wireless technologies used in an
industrial environment must be able to coexist without disrupting each other. If multiple
networks operate in one facility, a frequency management should be applied as part of
administration.
If it is not possible to mount the device outdoors, connect a remote antenna to the antenna
terminal and mount the remote antenna outdoors. The antenna cable should not be longer
than 15 m.
3.1.2 Antenna Characteristics
The antenna is an omni-directional dipole antenna. If you point the antenna upwards, the
signal radiates horizontally with an angle of approx. 45 degrees above and below the
horizontal (donut shaped). Allmost no signal will be radiated directly above and below the
antenna. Consider this when planning a WirelessHART network. The height differences
between wireless devices in a network should not be too big.
This is only valid for an antenna placed outdoors with no metal surfaces near. The radiation
pattern changes significantly when metal surfaces are close to the antenna.

3.2 Mounting the Gateway
Danger!
Electrostatic discharge hazard
The device contains non-conductive plastic parts. Care must be taken when operating the
installed device because of possible electrostatic charges. Electrostatic charged surfaces
may cause an ignition spark.
Electrostatic charges must be avoided. For example, do not rub the device and never clean
plastic surfaces with a dry cloth. Always use a damp cloth instead.
Danger!
Check cable glands
The IP degree of protection can not be ensured if the cables and cable glands are not fitted
correctly.
To ensure the IP degree of protection
• all screws of the housing / housing cover must have been tightened with the appropriate
torque,
• only cables of the appropriate size must be used in the cable glands,
• all cable glands must be tightened with the appropriate torque,
• all seals must be undamaged and fitted correctly,
• all empty cable glands must be sealed with appropriate plugs.
The mounting location should be well accessible for mounting and electrical installation.

Danger!
Explosion hazard in Zone 2 when operating powered Gateway
If the Gateway is installed in Zone 2 and connected to power, there is an explosion hazard
when operating DIP switches, buttons or connecting/disconnecting cables.
The operation of DIP switches/buttons and the connection/disconnection of any cables in
Zone 2 is only permitted in the absence of a hazardous atmosphere or if the device is
disconnected from power!
The Gateway is equipped with a fully galvanic isolated 10 Base-T/100 Base-TX Ethernet
interface. You may connect the Gateway to an existing Ethernet hub, switch, router or
directly to a PC.
Open the housing cover to access the terminal blocks.
Note!
Keep in mind that an access point of the Ethernet network has to be available. The
maximum length of the cable running from the Gateway to the access point is 100 m,
depending on cable type and communication speed.

Note!
Tension relief and bending radii
Ensure sufficient relief of tension on the cables during installation and note the minimum
bending radii of the cables.
Pin assignment of the Ethernet plug
You do not need an Ethernet plug to connect the Ethernet cable to the Gateway. However,
you need an Ethernet plug at the other end of the cable to connect the cable to an Ethernet
hub, switch, router or PC.
There are different standards for Ethernet plugs: T568A and T568B (see following
figure/table). The only difference between these standards is that certain wires are
connected to different pins of the plug. It is not important which standard the plug uses.
But, depending on the plug standard, there are two different ways of connecting the other
end of the Ethernet cable to the Gateway.

Crossover or straight through wiring
There are different types of Ethernet cables, depending on the application. In a straight
through cable, both cable ends have T568A plugs or both ends have T568B plugs. In a
crossover cable, one end has a T568A plug and the other end a T568B plug.
• Use straight through wiring if you connect the Gateway to a switch, hub or router (see
Figure 3.8 on page 25).
• Use crossover wiring if you connect the Gateway directly to another ethernet device
(e.g. a PC) without a switch, hub or router (see Figure 3.8 on page 25).
Note!
Latest network interface cards and hub/switch/router versions can be able to automatically
adjust to the cable version used, also if this is not the applicable one according to the
guidelines given in this manual.

Danger!
Explosion hazard in Zone 2 when operating powered Gateway
If the Gateway is installed in Zone 2 and connected to power, there is an explosion hazard
when operating DIP switches, buttons or connecting/disconnecting cables.
The operation of DIP switches/buttons and the connection/disconnection of any cables in
Zone 2 is only permitted in the absence of a hazardous atmosphere or if the device is
disconnected from power!
The Gateway is equipped with a fully galvanic isolated RS-485 interface. The interface is
daisy-chain capable through its duplicated RS-485 terminal block.
A terminating resistor is integrated and may be switched on/off by using the corresponding
DIP switch inside the Gateway housing (see chapter 6.1) . It is also possible to switch on/off
the terminating resistor via software (see chapter 5.5.1).
If the RS-485 cable ends at the WirelessHART Gateway and is not routed to other devices
(no daisy-chain connection), activate the terminating resistor to ensure reliable RS-485
communication.
Note!
Keep in mind the location of the Modbus PLC or DCS. The maximum length of the cable
running from the Gateway to the PLC/DCS is 1200 m (at reduced communication speed).
Use shielded twisted pair (STP) cables only.

Possible loss of connection when changing Network ID
If you change the Network ID parameter of an already operating WirelessHART network,
be aware that the Gateway will store the new network ID. However, the new network ID will
only be applied the next time the network is reformed (please note that reforming the
network can take a long time). When the new network ID becomes active after reforming
the network, the connection to the other WirelessHART devices could get lost if they still
have the old network ID.
After changing the network ID in the Gateway, the new network ID has to be written to each
wireless device in the network using either the wired or the wireless connection. Here, too,
the new network ID will be stored in the device and is applied only the next time the
network is reformed.

5.4.2 Instrument List
Here you will find information on the devices within the WirelessHART network. The
Instrument List represents the Gateway's virtual I/O system (see chapter 2.2.3) and
displays the cached parameters and values of all sub devices.
Note!
The Instrument List is stored in a non-volatile memory. Card/channel number assignment
will remain the same after a Gateway power-up or software restart.
Note!
Please keep in mind that the dynamic values of each sub device (analogue value, PV, SV,
TV, QV) are only cached by the Gateway if the respective sub device publishes those
values (see chapter 2.2.4).
After a network restart, the Instrument List needs time to rebuild. During this time, some

5.4.3 Burst Lists
Description
: OK, device connected and identified.
: No communication possible.
: Communication possible, device not identified.
Burst mode is a special communication mode in which a HART slave device sends
responses to a particular HART command without being polled by the master. Normally, a
HART slave device only responds when being polled by the master.
When burst mode is used, a HART slave device can publish data (for example process
values) independently in regular time intervals. Alternatively, data can be published if the
value has changed by a significant amount, has reached a certain threshold level or has
not been updated within a default reporting time.
The gateway maintains a burst message list comprising, for each sub device, the specific
commands currently being published within the WirelessHART network. The burst list is
volatile and therefore reset after power-up or network restart.
Note!
It is important to consider the following publishing guidelines for each device in the wireless
network. Only if publishing of at least one command is activated in each wireless device,
the gateway is able to cache up-to-date device status information, even if no other HOST
activity is ongoing. Up-to-date data is important for efficient device status monitoring.
You will find the publishing parameters of most WirelessHART devices in the "Burst Mode"
menu of the device DTM.
Device publishing guidelines
• It is recommended that command 48 (Read Additional Device Status) is always
published to ensure caching of the related status information. A publishing interval of
approx. 1 minute is generally the best choice. When configuring WirelessHART
adapters, command 48 allows proper identification and management of a sub-device list
change without direct Host intervention.
• Publishing of at least one command should always be enabled at the wireless device
level to allow configuration change detection and automatic device cache invalidation
without direct Host intervention.
221981 2011-07
54
WHA-GW-*
Configuration
• Publishing of at least one command will also ensure that the cached status information
is updated for cached configuration commands.

The Instrument List backup table is a backup copy of the Instrument List (see chapter
5.4.2). Just like the Instrument List, the Instrument List backup contains every device in the
WirelessHART network. The Instrument List backup offers you the following possibilities:
• Export the Instrument List backup to a file on your hard drive,
• Import an Instrument List backup from a file,
• Load Instrument List from device or store Instrument List backup to device.
Especially the export/import function can be very useful. For example, if a Gateway has to
be replaced with a new one, the new Gateway normally rebuilds the WirelessHART
network from scratch. The devices in the network get different Modbus addresses and
different positions in the virtual HART I/O structure than they had before.
By loading an Instrument List backup of the old Gateway into the new one, the wireless
network is rebuilt in exactly the same way as before.

6.4 Network Enhancement
Once the WirelessHART network is running, there are some simple measures that will help
enhancing network performance and reliability. Those measures are described in the
following.
Note!
After having installed and set up a wireless network, give the network a couple of hours to
stabilize itself before taking the following steps.
Verify Connections
Check that each device has joined the network and is communicating properly (see
chapter 6.2.2).
If you cannot establish a connection to a device, the device is probably too far away or an
obstacle blocks the radio waves. In this case, add an additional device to bridge the gap.
Eliminate Bottlenecks
If the messages of several devices all have to pass through one single device to get to the
Gateway, the network has a bottleneck. If the device at the bottleneck fails, whole parts of
the network get cut off from communication because there are no alternative paths to route
messages.
To eliminate bottlenecks in a wireless network, add at least one device near the bottleneck
to provide redundant communication paths (see Figure 6.14 on page 82). There should
always be at least two communication paths from one device to another.

81
WHA-GW-*
Operation
Figure 6.14Eliminating a bottleneck
1 Bottleneck

3 Possible position of an additional WirelessHART device eliminating the bottleneck
Expand the Network
In an industrial environment, there are several potential obstacles for radio waves, for
example buildings, walls, pipes, or even moving obstacles like trucks. Those obstacles can
reflect, bend, diffuse or block radio waves. The effects of reflection, bending and diffusion
create new waves which interact with the original ones and with each other. They can
amplify or nullify each other.
Due to the interference of reflections, moving the antenna a few centimetres can help. If
there are obstacles blocking transmission between wireless devices, add additional
devices to provide alternative communication paths. The more devices exist in a
WirelessHART network, the more reliable it gets.
Optimize Coexistence with other Wireless Networks
WirelessHART networks use the frequency spectrum between 2400 ... 2483.5 MHz
according to IEEE 802.15.4. Various other wireless technologies also use this frequency
spectrum, for example WLAN (IEEE 802.11) and Bluetooth (IEEE 802.15.1). Measures
must be taken to ensure that the various wireless technologies do not affect each other.
82
221981 2011-07
WHA-GW-*
Operation
If there are problems with other wireless technologies disrupting the WirelessHART
network, you should configure the Gateway to skip certain channels known to provide
persistent interference (Blacklisting). Blacklisting is a user configurable feature and is
useful when other wireless networks are in the physical environment of the WirelessHART
network (see chapter 5.4.1).
If possible, also actively manage frequencies used by other networks. If possible block the
usage of certain channels already used by the WirelessHART network (frequency
management).

• HART CMD 3 dynamic variables mapped into input registers
• 2 input registers map a single HART dynamic variable
• 32bit HART floating point format used
• Status information mapped on dedicated input registers
The Modbus implementation maps HART dynamic input variables over Modbus input
registers and also uses input registers to provide device-related status information. The
Modbus implementation is based on the following assumptions:
• The HART CMD 3 dynamic variables are used for Modbus mapping.
• For Modbus access, CMD 3 publishing must be enabled for all relevant devices.
• The Gateway caches the relevant CMD 3 information. Modbus commands will therefore
access the internal Gateway memory.
• Modbus input registers are only supported if they are associated with HART dynamic
input variables.
• A device can either be a WirelessHART device or a wired HART device connected to a
WirelessHART adapter.
• WirelessHART and wired HART devices are mapped independently within the Modbus
input registers. Wired devices are not necessarily mapped consecutive with the
associated WirelessHART adapter.

6.5.2 Modbus Mapping Description
Note!
The Modbus starting register of each device in the WirelesHART network is displayed in
the DTM (Parameter > Wired Communication > Protocols > Modbus, see chapter
5.5.4).
Figure 6.15Parameter > Wired Communication > Protocols > Modbus
Mapping rules
Each HART device is mapped into 12 consecutive Modbus input registers. The first device
is mapped starting at register 30013, the second starting at register 30025, and so on. The
input registers can be read using Modbus function code 04 (Read Input Registers).
The order of HART device mapping starting from register 30001 is the same as the order of
the HART devices returned by the gateway command 84 (HART CMD 84, Read sub-device
identity summary). For example, the HART device that you can read by using CMD 84 with
the sub-device index = 1 is mapped starting at register 30013. The device that you can
read by using CMD 84 with the sub-device index = 2 is mapped starting at register 30025,
and so on.
The information about the WHA-GW itself is mapped into registers 30001 to 30012.
To find out the starting register of a certain sub-device, use the following formula:
SIR = 30001 + 12*(SDI)
"SIR" being the starting input register of the associated HART device and "SDI" being the
CMD 84 sub-device index value.

The following table shows the exemplary mapping of the first two HART devices, i.e. the
ones associated with SDI = 1 and SDI = 2.

Dynamic variable mapping format
For each HART device, the 5 possible CMD 3 floating-point dynamic variables are
sequentially mapped (the CMD 3 units code values are not mapped). If a device does not
support a specific dynamic value, a "NaN" (Not a Number) floating-point value is returned
(namely, 0x7F, 0xA0, 0x00, 0x00).
The CMD 3 dynamic variables follow the IEEE-754 (IEC 559) single-precision floating-point
format (see following table).
Sign of the Fraction 8-bit Exponent 23-bit Fraction
The same format is also used for the Modbus 32-bit floating point values.
The Modbus protocol does not explicitly specify any 32-bit data element. However, the
usage of 2 consecutive 16-bit registers is the de-facto standard way to map a singleprecision IEEE-754 floating-point value. Note that the Modbus floating value will be
transmitted in the "big-endian" style. For example, the number 123456.00 as defined in the
IEEE-754 standard appears as follows:
Byte 0 Byte 1 Byte 2 Byte 3
86
0x00 0x20 0xF1 0x47
This number will be transmitted from the Gateway to the Modbus master in the following
sequence:
47 F1 20 00
where "00" – the less significant byte – is the first one to be transmitted.

qualitiy is poor.
The Gateway is connected to the
Ethernet with a straight through
connection although a crossover
connection is neccesary (or vice
versa).
The Ethernet parameters of the
Gateway are incorrect.
The Local Area Connection
Properties of your PC are not
configured correctly.
If you are parameterizing via the
web interface: Maybe your web
browser uses proxies.
Wrong parameters (e.g. COM
port, address range) are set in the
communication DTM.
The terminating resistor is not
activated.
Try powering the Gateway down
and up again. If the problem
persists, please return the device
to P+F for repair.
Please contact P+F customer
service for guidelines.
Access the Gateway's Ethernet
interface (see chapter 2.4).
Interchange the green wire with
the orange one, and the
white/orange wire with the
white/green one. (see Figure 3.10
on page 26). This action changes
a crossover connection into a
straight through connection and
vice versa.
Check the Gateway's Ethernet
parameters (see chapter 5.5.2).
Configure the Local Area
Connection according to the
instructions given (see chapter
4.5).
Deactivate proxies in your
browser.
Check the parameters in the
communication DTM (see chapter
4.6.2). Also check the COM port
configured on your PC(see
chapter 4.4) and the baud
rate/polling address configured via
the DIP switches in the Gateway
housing (see chapter 6.1.2).
If the RS-485 cable ends at the
Gateway (Gateway is last device),
activate the terminating resistor
via the DIP switch inside the
Gateway housing (see chapter
6.1.2) or via the DTM (see chapter
5.5.1).

Gateway's Instrument List.
Alternatively, check the wireless
communication parameters (join
status) of the device via a HART
modem connected to the device.
Check the wireless
communication parameters of the
device via a HART modem
connected to the device. The
device and the Gateway must
have the same network ID and
