2 Product Specifications
2.1 Functional Overview
The WirelessHART gateway is the interface between the WirelessHART network and the
process control system. It supports WirelessHART networks with up to 250 network
participants and provides an RS-485 interface as well as an Ethernet interface. Both interfaces
transmit the HART or MODBUS protocol. OPC connectivity can be realized via the HART OPC
server. It can be configured via the device type manager (DTM) or device description (DD) in
connection with a configuration software. Furthermore, it provides a web interface for direct
access via a web browser.
Key Features
■Graphical network analysis
■Simple and automatic configuration options
■Ethernet and RS-485 interface
■HART and MODBUS protocol via both interfaces
■Input WirelessHART wireless interface
■24 V DC supply
■Redundant power supply connections
2.1.1 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.

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.
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.
2.1.2 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.
2.1.3 Virtual Remote I/O system
The WirelessHART gateway makes wireless communication accessible to host systems
capable of HART technology through the following principles.
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 2.2 on page 11
The WirelessHART gateway assigns a virtual I/O card to each WirelessHART device and
stores card and channel values in a 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 its connection to the WirelessHART gateway, it keeps its
position in the list and stays assigned to the respective I/O card. If the connection to the
WirelessHART gateway is re-established, the WirelessHART 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 WirelessHART gateway was lost, the field devices regain their previous
position as soon as the connection is re-established.
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.
Note!
This list is stored in a non-volatile memory of the WirelessHART gateway. The card and
channel number assignment will remain the same after a restart of the WirelessHART gateway
or software.

2.1.4 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 automatically cached
by the WirelessHART gateway (upon read). Other commands, for example dynamic values, are
only cached if the respective field device publishes them (upon publishing). See chapter 5.4.2
Burst Lists
The responses to the commands listed in the following table are cached in the WirelessHART
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).
Information Cached by WirelessHART Gateway
Status Information Caching
The WirelessHART gateway caches the device status byte separately for each wireless or
wired device. The device status will be cached from any type of received message, no matter if
from a wired or wireless device, or if it is a "published" or "normal" response.
The extended device status byte is cached in a similar way, but is available only for wireless
devices.

3.1 Mounting Considerations
3.1.1 Positioning the WirelessHART Gateway
Install the WirelessHART 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
WirelessHART 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.
■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.
■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 plant, a frequency management should be applied as part of
administration.
If it is not possible to mount the WirelessHART gateway outdoors, you can also connect a
remote antenna to the WirelessHART gateway and mount the remote antenna outdoors.
3.1.2 Antenna Characteristics
The included antenna W-ANT-2400-2DB-ROD (Part. No. 215520) is an omnidirectional 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). Almost 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 valid only for an antenna, which is placed outdoors with no metal surfaces in immediate
vicinity. The radiation pattern changes significantly when metal surfaces are close to the
antenna.
The following diagrams show the antenna gain in two different planes.
