2Technology Overview
2.1 WirelessHART Network
A WirelessHART network consists of a host; a WirelessHART gateway, network manager, and
access point; and one or more WirelessHART field devices and/or adapters. The Wire-
lessHART network is described in the HART specifications published by the FieldComm
Group.
2.2 Host
A host provides control or aggregates data in a network. It often incorporates a Human Ma-
chine Interface (HMI) between the operator and the process. In the context of WirelessHART
networks, a host usually communicates to a WirelessHART gateway using a protocol such as
ModbusTCP or similar.
2.3 WirelessHART Gateway
The WirelessHART gateway provides protocol conversion between the protocol used by the
WirelessHART network and that of the host.
The WirelessHART access point and network manager are often implemented in the same de-
vice or physical piece of hardware as the WirelessHART gateway. When this is the case, it is
common to refer to the combination of all three entities as a WirelessHART gateway or
simply a gateway. Although the term gateway only refers to the protocol-converting portion
of the device, the assumption is made that most gateways contain the network management
and access point capabilities.
2.4 WirelessHART Client
The WirelessHART client provides a connection between the wireless network and the gate-
way. Wireless devices connect to the gateway using a process called “joining.” During this
process, wireless devices detect and respond to a network advertisement, request to join the
network, authenticate to the network, and are allocated bandwidth for communication of
HART message traffic. When devices have fully joined a network access point, they are
termed “operational” and are able to communicate data via a request/response method
known as client/server; or are able to “burst” data on a pre-determined interval using a pub-
lisher/subscriber method. Although both methods allow for data to be passed to the host,
the burst method is preferred because of its efficient use of the bandwidth.
Consider the following example:
Request/response:
Message 1: Host sends request message with request for data to a field device.
Message 2: Field device sends response message with response data to host.

TE C H NO LOG Y OV ERV I E W
NE T WO R K M A N AG ER
4J NO 0 00 30 8 A 13
Burst:
Message 1: Field device publishes pre-configured message data such as a primary variable or
loop current to the Host on a fixed interval.
From this example it is obvious that, the Burst method results in about half the network traf-
fic, freeing the network to take care of other tasks such as keeping track of device configura-
tion changes, communicating with joining devices, searching for lost devices, or gathering
statistics on the health and stability of the network. In most cases, an efficient network will
use a mixture of both communication methods.
The WirelessHART access point can send messages over the WirelessHART network using its
IEEE 802.15.4-compliant radio transceiver. WirelessHART uses the first 15 channels of the
IEEE 802.15.4 standard for communication and efficiently avoids interference and maximizes
the bandwidth in the 2.4 GHz spectrum by continuously frequency hopping between chan-
nels according to a frequency hop sequence. This should not be confused with message
hops, which refer to the paths that messages take between devices in a mesh network.
2.5 Network Manager
The WirelessHART network bandwidth is allocated by the network manager. The network
manager assigns Absolute Slot Numbers (ASN), or message slots, to field devices wishing to
publish burst messages over the network. Devices that have not been allocated bandwidth
on the network are not able to communicate with the gateway and are not able to publish
messages on the network. The network manager is responsible for the “joining” of field de-
vices, allocation of network bandwidth, managing network security, maintaining a list of net-
work devices, and providing communication paths through the mesh network.
The network manager is responsible for broadcasting the existence of the network to pro-
spective field devices and instructs devices already joined to the network to broadcast on its
behalf. Devices may discover the network via an advertisement from any other device already
on the network. This advertisement contains a network ID that can be used to provide a
unique distinction between otherwise overlapping networks. Only devices that have been
programmed to join the network will respond to advertisements of the network ID.
Once an advertisement is received, the device may request to join the network by responding
with the correct join key of the network. The join key is a 32-character, hexadecimal string
that prevents unauthorized devices from joining the network. The network manager rejects
device join attempts by any devices not providing the correct join key.
2.5.1 Network ID and Join Key
After the network manager validates the network ID and join key of the requesting device,
the device is allocated with a session key to use it for communicating with the network man-
ager. The session key may be a static key or it may be periodically changed or “rotated” by
the network manager as an increased security measure. Only devices which have been allo-
cated communication bandwidth and have valid session keys can communicate on the net-
work. To further increase security, each field device is given a unique session key such that
only the network manager can understand and decrypt the data from the field device.
2.5.2 Message Hops
The network forms around the access point, and all devices which can communicate directly
with the access point are described as being one “hop” from the access point. Other devices
may join the network as long as they can communicate with at least one other device that is

WI R ELES S HA RT FI E LD D E VI CE
TE C H NO LO G Y O VE R V IE W
14 4J NO 0 00 30 8 A
connected to the network. Given this logic, devices could be one or more hops from the ac-
cess point as long as they have neighbors (or their neighbors have neighbors) which can
communicate directly with the access point. Messages may be passed along from device to
device in the wireless mesh until they reach their destination, either the host or a remote
field device. In this way, the messages follow paths from the source device to the host and
vice versa.
2.6 WirelessHART Field Device
The WirelessHART field device can connect into a plant process and can send and receive
data over the mesh network. The WirelessHART field device typically consists of a sensor, a
transducer, and a transceiver.
2.6.1 Sensors
The sensor connects into the plant process and measures (or controls) some aspect of the
analog process, such as temperature, pressure, level, flow, position, etc. The sensor may also
provide a discrete connection to the process as is the case with remote I/O field devices.
2.6.2 Transducers
The transducer converts or scales the measurement, so it may be used by a host system in
the context of the process. Proportional-Integral-Derivative scaling or conversion takes place
in the transducer portion of the field device.
2.6.3 Transceivers
The WirelessHART field device transmits or “hops” HART messages wirelessly to other de-
vices or directly to the access point using an IEEE 802.15.4 compliant radio transceiver.
2.7 HART Field Devices and Wired 4… 20 mA Field Devices
Traditional HART capable “smart” 4… 20 mA devices are similar to WirelessHART field de-
vices except that they use a Frequency Shift Keyed (FSK) HART modem to communicate over
a wired loop instead of communicating via a radio transceiver.
2.8 WirelessHART Adapter
In many cases, it is desirable to use existing HART field devices as part of a WirelessHART
network. This is possible through the use of a WirelessHART adapter, which bridges the con-
nection between the wired and wireless transmission mediums. WirelessHART adapters con-
tain a WirelessHART transceiver for connection to the WirelessHART network, as well as a 4…
20 mA FSK HART modem, which is used to communicate directly with a HART device via a
wired loop.
2.8.1 Connecting to a HART Device
A WirelessHART adapter may be used with a HART field device to collect messages received
over the HART 4… 20 mA loop and retransmit these messages via its WirelessHART trans-
ceiver. In the case of HART devices that transmit their Primary Variables (PVs) digitally, multi-
ple HART devices may be connected in the same wired loop as a single WirelessHART

TE C H NO LOG Y OV ERV I E W
W IR E LE SS H AR T C OM M A ND S
4J NO 0 00 30 8 A 15
adapter, and the WirelessHART adapter may be capable of adapting or bridging the commu-
nication between the WirelessHART network and multiple wired devices.
2.9 WirelessHART Commands
The WirelessHART capable host, gateway, network manager, access point, adapters and Wire-
lessHART field devices all communicate using a set of both standard and device specific
HART commands. These commands comprise the Highway Addressable Remote Transducer
(HART), protocol and form the backbone of both HART and WirelessHART communication
standards. These commands are classified into several groups and may or may not be sup-
ported by a given network entity.
2.9.1 Universal commands
The commands must be supported by gateways, adapters, WirelessHART and wired 4… 20
mA HART devices. They are used to read the process variables and device status from the
field devices.
2.9.2 Common practice commands
These commands are strongly recommended for implementation by gateways, adapters, and
field devices as they provide additional functionality for communicating and configuring
with field devices.
2.9.3 Wireless commands
These commands are divided into several sub-categories which are required to be imple-
mented and supported by network manager and access point entities, gateways, adapters,
and WirelessHART field devices. The commands handle network formation, maintenance, and
security as well as other background functions required by the network.
2.9.4 Device-specific commands
These commands provide device-specific functionality to a field device. Additionally, device-
specific commands may also be vendor-specific such that they provide unique features or
additional capabilities to a vendor’s WirelessHART field devices.

3Basic Features of AWIN GW120 Gateway
The AWIN GW120 is a WirelessHART gateway. It can connect with up to 100 WirelessHART
field devices and convert the HART data to Modbus TCP data for easy integration into almost
any ModbusTCP based host system. The connection can be established via the onboard
Ethernet ports. HART to Modbus TCP mapping is available in both automatic and manual
modes. In automatic mode, the gateway automatically assigns registers to available parame-
ters. Whereas, in case of manual mode the user has to supply a custom Modbus list in the
form of an XML file.
3.1 Get Familiar with AWIN GW120
The AWIN GW120 is a DIN rail-mount wireless device with a protection rating of IP20 (see Fig-
ure 1). The gateway has RJ45 connectors for connection of Ethernet devices. The Wire-
lessHART antenna connector allows remote mounting of the antenna. The gateway comes
with built-in LEDs, see description in Table 4.
