WirelessHART Device TypesWirelessHART Device Types

WirelessHART divides into 2 main device types

WirelessHART GatewayWirelessHART Device

Every HART device can become a WirelessHART device by connecting a WirelessHART adaptor to it

WirelessHART GatewayWirelessHART Gateway

Is the interface between the wired structure and the wireless networkInstallation in Zone 1

For Zone 2 application a manufacturer declaration can be issued



Serves up to 250 WirelessHART field devicesConnections/cable glands

2 for redundant supply (24Vdc)2 RS485 (daisy chaining)1 Ethernet (10Base-T and 100Base-TX)

RS485connection

DIP switches to configure- Polling address- Baud rate- RS485 termination- Security mode


RS485 InterfaceRS485 Interface

2 Terminals blocks to have “daisy chain”capabilityIn case WirelessHART GW is the RS485 participant on the bus

RS485 terminator must be switched onVia DIP switch 7 = ON

ORVia (software) configuration settings

Supported baud rates via RS4859600, 19200, 38400 or 57600 kBaudVia DIP switch 5&6 or (software) configuration settings



Terminals/Connection

Supported ProtocolsHART (115 kbit/s)Modbus RTU



RS485 polling address can be configured via DIP switches 1 to 4

Addresses 0 to 15RS485 polling addresses can also be configured via (software) configuration settings

Must be used in case higher addresses than 15 are requiredHighest possible addresses

HART protocol 63Modbus RTU 247


EthernetEthernet

Some Laptops do support “Auto cross over”functionality

In this case a cross over cable OR an straight trough cable can be used

In case “Auto cross over” is NOT supported there are two possibilities

Direct connection between WHART GW and Laptop/PCConnection via a Hub or Switch


CablingCabling

Direct connection

Connection via Hub/Switch

Straight through cable


Ethernet Wiring (cable)Ethernet Wiring (cable)

There are two types of plug availableT568A and T568B

Both can be used for straight through and cross over cable

2 T568A plugs straight through2 T568B plugs straight through1 T568A and 1 T568B cross over

For communication we require “just” 2 pairsTx = transmit dataRx = Receive data

Battery lifetime up to 5 years


Mounting of the AdaptorMounting of the Adaptor

Adaptorrotatable

Antennarotatable

Due to rotatable adaptor and antenna, the antennaCan be adjusted to the required position (Fresnel zone)

At leastThe Join keyThe Network ID

Must be configured via a HART modem (terminals 7 and 8)To be able to do this the push button must be pressed ≥ 10 s

Start configuration modeIndication via LED’s



The adaptor will always be powered by the battery

2 batteries (located in the cover), connected in seriesEach offers 3.6V and 19Ah

The instrument can be fed fromBattery (Battery life time!)

Passive two wire deviceExternally

Active four wire deviceLoop powered

Two wire device with external powerConnected to an existing 4 … 20 mA loop

HART device with external power



By connecting to terminals 1 and 2 the following functions are possible:

Loop-powering of the field device by adapterCurrent measurement via 4...20 mA interfaceDigital HART communication

PV has to be transmitted wirelessBattery life time will be reduced

Loop powered



Two-wire device with external power supplyBy connecting to terminals 2 and 5 the following functions are possible:

Current measurement via 4...20 mA interfaceDigital HART communication

The power supply is connected to terminals 3 and 4.



HART device with external powerIf the adapter is to be retrofitted to a device powered by an existing

PLC ,Remote I/O orDC power supply

with communication resistor.Following function are possible:

Digital HART communicationHART multidrop mode for 2, 3 or 4 devices



For new installations, the power connection can be made via terminals 3 and 4, as terminal 3 is connected internally to terminal 6 and terminal 4 to terminal 5Easier wiring



Functionality Push button when battery is connected



Functionality Push button when battery is disconnectedPress button first and then connect battery
