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. These commands are used to read the process variables and device status
from the field devices.
2.9.2

Common practice commands

The 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

The commands are divided into several sub-categories which are required to be implemented
and supported by network manager and access point entities, gateways, adapters, and Wire-
lessHART field devices. These commands handle network formation, maintenance, and secu-
rity 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 ad-
ditional capabilities to a vendor's WirelessHART field devices.
