Introduction
What would you say if you could
carry the information for more than
100 HART®compatible field devices in
the palm of your hand? You can with
the HART Communicator. The
HART Communicator, with one
Fisher-Rosemount data pack 100,
empowers you to increase productivity,
reduce trips to the field, and gather
the kind of data you need to reduce
process downtime.
How about using the HART
Communicator? Is it easy to use?
How long does it take to learn? Can
you customize the screen to your
specific needs? Yes, it’s easy, fast to
learn, and you can customize the Hot
Key for your most frequent tasks. In
fact, when you connect the HART

Communicator to a HART device,
the tag and model number of the
connected device is automatically
displayed on the top line of the
LCD screen!
The standard HART Communicator,
with 12 MB of memory, contains the
device descriptions for all HART
devices, regardless of manufacturer.
It also holds up to 10 configurations.
But 10 configurations is often not
enough to meet your day to day
requirements. The Fisher-Rosemount
data pack 100 was designed to meet
this need. The Fisher-Rosemount data
pack 100 plugs easily into the memory
module to add enough memory for up
to an additional 100 configurations.
The data pack 100 may be removed
and kept as a permanent historical
record of instrument activity.
Whether you are taking information
from the field, back to the shop, or
from the shop to the device, you
have the information you need.
The HART Communicator is also a
data input device for your plant
database. With Asset Management
Solutions (AMS) software, you can
move information from your HART
Communicator directly to your PC.
The combination of the HART
Communicator and a PC equipped
with AMS software gives you an
instrument database that enables you
to more efficiently and effectively
manage the instrument assets that are
the foundation of your process.
The only device you’ll ever need to get information
from your HART instruments. The Model 275 HART
Communicator has device descriptions built-in for all of the devices in
the market today that are HART
capable. Period. No matter who
makes the device, the HART
Communicator can “talk
smart”! That means you
can reduce your investment in communicators
because the HART
Communicator takes care of all
of your needs. Every maintenance person
needs a HART Communicator. It’s an
investment in productivity.
Streamline regulatory documentation preparation
through access to historic configuration and as
found/as left data. It often takes longer to document
what is found in the field than it takes to make a
change in the device.
Combine the convenience of
the portable handheld
with the power of
AMS. Use your
HART
Communicator to
upload and
download information to and from all
of your HART
devices. Use your
Asset Management
Solutions software to
simply upload device information from your HART Communicator to your PC.
You no longer have to dig in file cabinet after file
cabinet for device information. All of the information
you need to satisfy regulatory requirements is at
your fingertips, from anywhere in the plant!
Any PC in the plant equipped with AMS can call up
information about any smart device in the plant.
That’s field power. That’s efficiency.
And most of all, that’s ease of use.

you to simulate an online connection to a specific
HART compatible device. The simulation mode is a
training tool that enables you to become familiar with
a device before configuring it in a critical environment.
Access the simulation mode through the Utility Menu.
Save
Save allows you to quickly store the current configuration data under the current Tag, Descriptor, or Name
by pressing the F2 key when appears as a
SAVE
dynamic label. Save As lets the user store configuration data under a user-specified Name Location
(Memory Module or Fisher- R o s e m o u nt data pack 100)
and Data Type (Standard, Partial or Full). Data may be
stored in the Memory Module or in the removable data
pack as a portable, nonvolatile file.
Data Type
The HART Communicator allows you to specify which
variables to save under the current configuration.
The three choices are:
● Standard—The set of all editable variables defining
a new device configuration.
● Partial—The set of all marked device variables.
● Full—The set of all variables.
Note: It is necessary to save a full configuration
The Memory Module is programmed with the operating
system software and the application software for a desired
set of HART compatible devices. This allows you to easily
expand the capability of your HART Communicator as
new field devices and product enhancements become
available. The Memory Module also stores device configuration data for up to 10 HART compatible devices.
Polling
The HART protocol allows for the connection of multiple HART devices on a single twisted pair of wires, or
over leased telephone lines. This concept is known as
“multidropping”. A single HART Communicator can
interface with multiple devices on one transmission
line. Communication between a host and a
multidropped device takes place digitally, with the
analog output fixed. In a multidrop installation, each
device is identified by a unique address (1-15). Use the
Auto Poll option to direct the HART Communicator to
search for a connected device at an address other than
zero. When Auto Polling is on, the communicator finds
every device in the loop and lists them by tag.
Hazardous Locations Certifications
The HART Communicator meets the Intrinsic Safety
requirements of the listed regulatory agencies.
Selecting one of the Hazardous Locations
Certification options provides for the required
labeling and information on the HART Communicator

HART Communications
The HART Communicator interfaces with any HART device from any wiring termination point in a 4-20 mA
loop, provided a minimum resistance of 250 ohms is present between the communicator and power supply.
The HART Communicator uses the Bell 202 frequency shift keying (FSK) technique. This technique superimposes high-frequency digital communication signals on the standard 4-20 mA transmitter circuit loop.
Because the net energy added to the loop is zero, communication does not disturb the 4-20 mA signal.
