Description
The HIM HART Interface Module unlocks the full
potential of new and in-place smart HART
multivariable transmitters and valves.
Converts HART to 4-20mA Signals
The HIM allows up to three additional analog
process variable measurements from a smart device
with no additional process penetrations or wiring.
Installed transparently across the 4-20mA
instrument loop, the HIM reads the HART digital
process data that “rides” on the loop wires. It
converts the digital information to up to three isolated
analog (4-20mA) process signals that are readily
accepted by in-place control systems, such as a
DCS or PLC.
Take Full Advantage of “Legacy” Instruments
The HIM lets you leave trusted (and paid for) smart
HART transmitters and valves in place, yet still take
advantage of all the information they have to offer.
Works With Every Smart HART Device
The HIM programs in minutes to interface with every
HART-compatible monitoring and control device:
• Multivariable Mass Flow Transmitters
• Dual-Sensor Temperature Transmitters
• Pressure Transmitters
• Coriolis, Magnetic, Ultrasonic and Vortex
Flow Meters
• pH Transmitters
• Radar and Hydrostatic Level Transmitters
• Valve Positioners and Damper Operators
The HIM HART loop monitor features a compact metal
housing that mounts on a standard DIN-rail or on a surface.
Features
• “Break Out” up to three analog signals. The HIM
provides additional analog signals proportional to a
multivariable transmitter’s primary, second, third or
fourth variables, or to user-selectable valve
parameters such as stem position.
• High/Low process and loop diagnostic alarms.
Two relays individually configure to respond to high
or low process conditions, or trip when transmitter
diagnostics or loop fault conditions are sensed.
• Sets up as a Primary or Secondary Master, or in
“Listen” Mode. User Configurable to act as a
HART Master, or in passive “Listen” Mode (see
page 4 for details).
• Normal or Burst HART Modes. The HIM can be
set to monitor smart HART instruments operating in
either Normal (Poll/Response) Mode or in Burst
Mode (see page 4 for details).

Smart HART® Loop
Interface and Monitor
Monitor Smart Multivariable
Transmitters
Unfortunately, unless you have a HART-based
control system, there is no way to continously
monitor the non-primary variables used to make the
calculation. Monitoring non-primary variables may
be desirable if one or more of the variables is
especially important to the quality or safety of the
process.
The HIM extracts useful information from multivariable transmitters that was previously unavailable
(see Table 1 for details).
For example, smart HART multivariable mass
flow transmitters sense three process variables
(pressure, temperature, and differential pressure or
raw flow). Using these, they perform an internal
calculation to derive mass flow. The mass flow
information is transmitted as a 4-20mA signal to the
control system.
Convert HART to 4-20mA Signals
The HIM reads the HART digital data that is
continuously being transmitted on the smart
transmitter’s analog loop wires (Figure 1), and
converts it to 4-20mA signals that can be readily
Figure 1. The HIM converts HART digital data to 4-20mA values proportional to a multivariable transmitter’s primary, second, third or fourth
variables. Its alarm trip outputs warn of unwanted high/low process conditions or of instrument diagnostic problems.

NOTES:
1. A HART loop can have only one Primary Master and one
Secondary Master. The HIM can be configured to act as
either a Primary Master, a Secondary Master, or in passive
“Listen” Mode. If a HART communicating control system is
acting as the Primary Master, the HIM is configured as the
Secondary Master. A HART Communicator cannot be used in
this configuration. As is shown in this illustration, if the control
system is non-HART communicating, the HIM is configured as
the Primary Master and the HART Communicator becomes
the Secondary Master. In “Listen” Mode, the HIM can be
used on the same loop with both a Primary and Secondary
Master (see page 4).
2. The HIM may be connected at any termination point in the
signal loop. The signal loop must have between 250 and
1100 ohms load for communication.

accepted by a DCS or PLC. This allows you to
continuously track a multivariable transmitter’s
second, third, and fourth variables. Each HIM analog
channel may be individually programs to monitor the
variables of your choice.
Monitor HART Instrument Diagnostics—Using the
Field Device Status Byte data that is available in
HART’s digital information, the HIM can be set to
initiate an alarm if any of the following fault conditions are detected:
Process and Diagnostic Alarm Trips
The HIM can be ordered with one or two alarm trip
(relay) outputs. These can be used just like a
traditional alarm trip to warn of high and/or low
process conditions based on user-set trip points.
They can also be set as diagnostic alarms to warn of
problems with a smart HART transmitter or valve
postioner.
Process High/Low Alarms—The difference
between the HIM and a traditional alarm trip is that
the HIM responds to HART’s digital information,
rather than to a loop’s analog signal. This allows the
HIM to be set to monitor any available dynamic
HART variable. For example, for a multivariable
mass flow transmitter, a relay can be set to trip when
the transmitter’s Third Variable (temperature)
exceeds a user-set trip point (Figure 1).
Each trip can be individually assigned. Both
alarms can be assigned to monitor one process
variable, or each can be set to respond to different
process variables.

Smart HART Valve Monitoring
The HIM HART Loop Interface and Monitor can also
be used to monitor smart HART valve positioners
and damper operators. Its 4-20mA analog outputs
can be used to keep track of important parameters
such as valve stem position, actuator pressure or
temperature. Alarm (relay) outputs can also be set
to alert of a smart valve condition such as valve
position (open/closed), low actuator pressure, and
positioner temperature (high/low).

Smart HART® Loop
Interface and Monitor
Programs as a Primary or Secondary
Master or in “Listen” Mode
Figure 2. When in “Listen” Mode, the HIM can be used on the
same loop with both a HART Primary Master and Secondary
Master.
SECONDARY MASTER
(HART Communicator)
The HIM can be configured as a HART loop’s
Primary or Secondary Master (in a HART master/
slave system), or in passive “Listen” Mode. A HART
loop can have only one Primary Master and one
Secondary Master
Primary Master—The HIM is set as a Primary Master when a
HART master is not present on the loop, such as when the control
system is non-HART communicating. This allows a Secondary
Master, such as a HART hand-held communicator, to be used on
the loop along with the HIM.
Secondary Master—When a HART-based control system,
such as an Asset Management System, is acting as the Primary
Master, the HIM can be set to act as the Secondary Master.
However, since a HART loop can have only one Primary Master
and one Secondary Master, a HART hand-held communicator can
not be used in this configuration.
“Listen” Mode—If the loop has a Primary and Secondary
Master, the HIM can be set in “Listen” Mode. In this mode, the HIM
can be added to a loop with a Primary and Secondary HART
Master because it connects passively without assuming the role of
a Master (Figure 2). In the “Listen” Mode, the HIM continuously
samples HART data from a smart instrument without affecting
normal loop operation. When using “Listen” Mode, the smart HART
instrument must be set in Burst Mode or a HART master must be
continuously polling the smart HART device (slave).
Sets to Read Normal or Burst Mode
When configured as either the loop’s Primary or
Secondary Master, the HIM can be set to monitor:

in "Listen" Mode
Figure 3. Up to 128 custom linearization points can be selected
and saved in the SPA’s memory to compensate for non-linear input
signals.
Normal Mode—The HIM polls the HART instrument 2 times
per second requesting the current process status and the HART
instrument’s diagnostic status. The HART instrument responds with
the requested data.
Burst Mode—In this mode, the smart HART instrument is
programmed to continuously transmit its process variable and
health status. The HIM samples the continuous HART data 3 times
per second.
Typically, HART instruments are used in the analog
mode, with a 4-20mA signal being sent by the HART
instrument to or from a control system (as shown in
Figure 1). In this mode, the HIM is set to monitor
address “0”. In a digital HART multidrop network, up
to 15 HART instruments digitally communicate on the
same wires. The HIM can be set to monitor any
instrument (address 1-15) within the network. The
HART address that the HIM monitors can be changed
at any time, allowing any of the instruments in the
network to be periodically monitored.

curve is beneficial when non-linear input signals must
be converted to linear output representations.
