HART 5/6/7
HART Basics
HART (Highway Addressable Remote Transducer) Protocol
is the global standard for sending and receiving digital
information across analog wires between smart devices and
control or monitoring system.
HART is a bi-directional communication protocol that
provides data access between intelligent field instruments
and host systems.
The majority of smart field devices installed worldwide
today are HART-enabled.

HART 5/6/7
HART Basics
The HART Protocol makes use of the Bell 202 Frequency
Shift Keying (FSK) standard to superimpose digital
communication signals at a low level on top of the 4-20mA.

HART 5/6/7
Differences between HART5/6/7
Revision 5
Makes up 99% of the installed base
Revision 6
Improves digital system integration
Revision 7
Optimizes wireless communications and
creates a single standard for wired and
wireless communications

HART 5/6/7
Features Introduced with HART 6
Long Tag
• Increases software tag length from 8 to 32 characters.
• This is by far the most requested feature from users – tag names are growing
• Allows matching the software tag of the device in the system exactly to the
device ID on engineering drawings – saving start up time and resources.

HART 5/6/7
Features Introduced with HART 6
Locate Device
• Flashes a unique message on the display of a device “0-0-0-0”.
• Allows the personnel in the field and control room to verify they’re
looking at the same device.
Slide 7
Endress+Hauser / Jim Coveart
HART 5/6/7
Features Introduced with HART 6
Digital Loop Check
• HART Revision 5 included analog loop check, which allows a user to set the
analog output to a specific value and confirm the loop is working as expected.
• This feature allows the user to set the HART digital values to confirm the HART
output values are outputting correctly, and that the device is configured.

HART 5/6/7
Features Introduced with HART 6
Multi-Variable Statuses
• Provides output quality information for all variables.
• This allows users to confirm the quality of their measurements beyond the
primary variable.

Wireless
• WirelessHART is the first global standard for wireless communications.
• HART Revision 7 provides a standard for wireless communications
Slide 12
Endress+Hauser / Jim Coveart
HART 5/6/7
Features Introduced with HART 7
Expanded Manufacturer ID
• Allows new manufacturers to register devices.
• HART manufacturers have increased beyond initial estimations.
Note - The expanded manufacturer ID has caused some trouble with
device identification in legacy systems.
Slide 13
Endress+Hauser / Jim Coveart
HART 5/6/7
Features Introduced with HART 7
Enhanced Multi-Variable Communication (8)
• Increases device output capability from 4 to 8 variables.
• Allows users to access more information about their measurement devices.
Slide 14
Endress+Hauser / Jim Coveart
HART 5/6/7
Features Introduced with HART 7
Time Stamp
• Time Stamp device data.
• Devices must have an internal clock.
• This allows a user to monitor the time between measurements for wireless
devices.
Slide 15
Endress+Hauser / Jim Coveart
HART 5/6/7
Features Introduced with HART 7
Trends
• A device can store up to 12 measurement points.
• Tracking trends in the device is beneficial for wireless devices used in
monitoring applications.
• For wired devices, this feature requires a user to manually record each data
point.
Slide 16
Endress+Hauser / Jim Coveart
HART 5/6/7
Features Introduced with HART 7
Synchronized Sampling
• A wireless feature that enables multiple devices to measure at a specific,
synchronized time.
• This is not available with wired HART devices.
Slide 17
Endress+Hauser / Jim Coveart
HART 5/6/7
Features Introduced with HART 7
A Note on Broadcast Messaging (Burst Mode)
• All HART Revisions (5, 6 and 7) include Broadcast Messaging capabilities, more
commonly referred to as Burst Mode. A device proactively sends out messages
about once per second instead of waiting for the host to request it.
• A wired HART Revision 5 or 6 device can be configured to burst all process
variables.
Changes to Broadcast Messaging with HART Revision 7
• A wired HART Revision 7 device improves on the burst capability by adding
variable status to the burst message – showing the quality of that measurement.
Slide 18
Endress+Hauser / Jim Coveart
HART 5/6/7
Features Introduced with HART 7
Report by Exception
• Message 1 includes process variables and status
• New messages 2 and 3 can be configured to communicate at a scheduled rate or
when a trigger condition is met – i.e. Report by Exception.
• Iif the primary variable (PV) exceeded a defined value (trigger), the device would
burst message 2 or 3 instead of message 1 to communicate that an exception
had occurred.
Slide 19
Endress+Hauser / Jim Coveart
HART 5/6/7
Features Introduced with HART 7
Event Notification
• Allows the user to select which device status information will be reported.
• A device can interrupt Message 1 with a notification that a specific event (as
defined by the user) has occurred.
• Examples of selectable events are device diagnostics, process alerts, overpressure limit.

HART 5/6/7
Do I Need HART 6 or HART 7 ?
• The vast majority of wired devices installed in user plants and available on
the market today are built to the HART 5 standard
• All HART versions are backward compatible and interoperable with each
other
• This backward / forward compatibility preserves investments of both users
and manufacturers as it enables a HART 5 control system to communicate
with a new HART 7 device the same as it communicates with a HART 5
device
• It also means that control system built to the latest HART 7 standard can
communicate with all versions of HART devices – HART 5, HART 6 or
HART 7
