Introduction
The HART protocol (Highway Addressable Remote Transducer) is used by many
4 ... 20 mA transmitters to enable digital communication for diagnosis and maintenance purposes. Many device parameters, but also measurement values, can be transmitted digitally to and from the device. Until now, HART has been using the wired 4 ... 20 mA loop as physical layer.
WirelessHART now allows for the wireless transmission of HART data. To be employable worldwide, WirelessHART utilizes the 2.4GHz Band (IEEE 802.15.4 wireless network) as physical layer. All WirelessHART devices form a mesh network in which every device is not just a measurement point, but also a repeater. This results in a bigger range of the whole network as well as an increased reliability through redundant communication paths.

2.3
The WirelessHART network is built up, organized and maintained by the WirelessHART gateway and is therefore self-organizing and self-healing. The gateway also takes care for connection to different HOST systems through different bus interfaces.
The WirelessHART gateway supplies the WirelessHART field devices with the necessary information for seamless network operation.
Functional Overview
The WirelessHART adapter WHA-ADP is an intelligent interface module that connects
HART and 4 ... 20 mA devices to a WirelessHART network. It transmits the measurement and diagnosis information acquired from the connected device(s) to a host application via the WirelessHART gateway WHA-GW.
Key Functions
• May be connected directly to a HART device or mounted separately. Up to 4 HART devices may be connected.
• LEDs for supply status, communication status and device status indication.
• Provides loop-power to the connected device. Alternatively, the connected device may be powered externally.
• Battery life estimation and "Low Battery" alarm
Scope of Delivery

Mounting Considerations
Positioning the Device
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. Please refer to the gateway manual for further information.
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.
• Consider moving objects that could affect the device's antenna range.
• Install wireless devices at leat 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. 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.

Mounting the device
The WirelessHart adapter can be mounted in one of three ways:
• direct connection to the field device,
• separate from the field device, but connected by a cable,
• when used as a repeater, as an autark unit.
Direct connection
The direct connection to a field device is made by means of an adapter piece which is
screwed into the cable entry at the side of the adapter (see chapter 3.2.1).
Separate mounting
The adapter can be mounted on a wall (see chapter 3.2.2), post (see chapter 3.2.3) or
other object, using the adapter wall/pipe mounting kit, which is available as an accessory.
The connection to the field device is made with standard installation cable and two cable glands. It is recommended that the blind plug be left in place until the electrical connection is made.
It is recommended that the WirelessHART adapter be installed separate from a field device when:
• there is insufficient space at the measuring point to mount the adapter on the field device,
• the signal reception at the measuring point is too weak for correct operation,
• the measuring point is subject to vibration above the permissible limits ( see
>>>>>>>>>> Technical Data ).
Supplied parts
Depending on the order, the following parts may be supplied:
• adapter piece for connection to a field device with a M20 cable entry,
• adapter piece for connection to a field device with a G 1/2 cable entry,
• adapter piece for connection to a field device with a NPT 1/2 cable entry,

Connected HART device(s)
It is recommended that the connected HART device is commissioned before the adapter. In addition to the device set-up the following HART parameters must be set:
• HART address: Sets the output mode of the device (0 = 4 ... 20 mA; 1 ... 15 = HART)
• If the device is connected to an existing 4...20 mA loop, use the address = 0!
• Otherwise use address = 1 for HART multidrop mode with a 4 mA current output.
• If more than one HART device is connected (up to 4 are allowed if externally powered), each must have a unique address between 1 and 14, e.g. 1, 2, 3, 4.
• Device Tag: Identifies the measuring point.
• Long tag or message: Identifies the device on the wireless network.
Long tags are available from HART Version 6.0 onwards. For earlier versions, the message is taken as the long tag.
To power the HART device for commissioning, e.g. through its display, a handheld device or PACTware via a HART modem, press the pushbutton in the adapter until the red LED flashes. The field device will then be supplied with power for 5 minutes (configurable in adapter DTM).
Note!
• It is not necessary to assign different HART addresses for different adapters – the address used on the network also incorporates the serial number of the adapter and is automatically unique to the adapter.
• 4 ... 20 mA devices require no pre-configuration. The scaling and any linearization are configured within the adapter DTM.

Joining the Wireless Network
For the device to join an existing WirelessHART network it needs to carry the network ID and join key of this network. Prior to joining the first time, the network ID and join key have to be configured using a wired connection .
To enter network ID and join key, the following requirements have to be met.
• A PC/Laptop is connected to the device using a HART modem.
• A PACTware project containing the HART communication DTM and the device DTM has been created.
In the joining phase the device sends a join request packet to the network manager. If the new device can be authenticated, the network manager responds with an activation packet and sets up links between the new device and other existing nodes. Furthermore, the new sensor will receive a 128 Bit encryption key.
Entering network ID and join key
1. In the PACTware project, right-click on the DTM of the device which is to join the WirelessHART network (WHA-*).

When a HART device is connected to the adapter, all parameters are read via the digital signal. It is possible, however, to connect a 4 ... 20 mA device to the adapter. In this case the 4 ... 20 mA signal can be scaled as desired in the DTM and a linearization can be made if necessary. In addition, current values can be set which correspond to the limits of the proportional range and the fault signal of the device. Should these current limits be violated, an appropriate warning or alarm signal is transmitted by the adapter.

Burst Mode Parameters
Burst mode is a special communication mode in which a HART slave device sends responses to a particular HART command on a predetermined, periodic schedule 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. Data can be sent as scheduled, or only if the value has changed by a significant amount or has not been updated within a default reporting time.
Up to 10 different burst modes can be set for the adapter or connected HART devices.

The more frequently burst messages are sent the more battery power is consumed, thus reducing battery lifetime.

Warning!
Caustic battery acid
Leaking battery acid can cause personal injury and damage to the device.
• Never use batteries that are leaking.
• Never use batteries with external damage such dents or deep scratches, even if no battery acid is leaking.
Warning!
Possible damage because of wrong battery
Using the wrong type of battery may cause damage to the device. The use of batteries other than specified in this manual also voids the IS certification.

Wireless Communication Faults
Fault
PACTware cannot find the device when communicating via
WirelessHART gateway WHA-
GW.
The device does not join the network.
Device disappears sporadically from the network
Possible cause
The device has not yet joined the network.
The device carries the wrong network ID and/or the wrong join key.
No battery or low battery
The device carries the wrong network ID and/or the wrong join key.
No neighboring WirelessHART devices are within the device's antenna range.
Device not mounted correctly
Device not trying to join
There are not enough neighboring
WirelessHART devices within the device's antenna range.
Corrective action
The joining process may take a while. Check the join status in the gateway's Instrument List.
Alternatively, check the wireless communication parameters (join status) of the device via a HART modem connected to the device. If the device does not join, check the next fault.
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 join key.
Check that a fresh battery of the correct type is inserted.
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 join key.
• Check the number of neighbors in the device DTM (wireless communication parameters).
There should be at least 2 neighbors.
• If there are no reachable neighbors, check the device's mounting position: Are there any obstacles? If yes, change the mounting position.
• If there are no reachable neighbors and you can not change the device's mounting position: Try moving an other
WirelessHART device in the network, or adding a new one.
Check that the adapter has been mounted correctly (see chapter
Check whether the device is trying to join the network (LEDs): if not, start a new connection attempt by pressing the correct button (see

Battery not connected or exhausted
Switch in the communication resistor or connect a 250 resistor across terminals 5/7 and
• Check the connection, if necessary replace the battery.
Power supply parameters are incorrect
Connected field device has a very low impendance - the adapter interprets this as a short-circuit and switches off the power
• A simple check is to shake the adapter or battery unit - if you hear liquid, the battery still has life.
• Find the correct parameters in the device manual and enter them into the DTM (see chapter
• Connect e.g. a 250
resistor in series with the device.
• Parameters can be read from a
HART device only.
