HIM
Smart HART Loop
Interface and Monitor
The HIM
The Moore Industries HIM HART Interface Module
unlocks the full potential of new and in-place HART
multivariable transmitters, valves, meters and other
smart instruments.
Converts HART to 4-20mA Signals
The HIM allows up to three additional analog process
variable measurements from a multivariable transmitter or valve with no additional process penetrations.
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 for up to three isolated analog (4-20mA) process
signals that are readily accepted by in-place control
systems, such as a DCS or PLC.
Provides Process and Diagnostic Alarms
Relay alarm trips (optional) can be individually user-set
either to trip when unwanted high/low process conditions occur, or provide a diagnostic health warning to
alert of loop or instrument fault conditions.
Takes Advantage of Legacy Instruments
The device lets you leave existing 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 instrument can be programmed in minutes to interface with every HART-compatible monitoring and control device.

Configuring the HIM
One of the benefits of the HIM is that there are no
internal or external controls to adjust or settings to
change. All operating parameters are set using the PC
Configuration software.
Once these software settings are made, they are
downloaded to the monitor in the form of a Configuration
File and stored in the unit’s non-volatile memory. You
can choose to save a backup copy of the file on your
PC hard drive or external media. The HIM communicates with the PC through a proprietary communications cable to the PC’s serial (COM) port.
Begin by installing the PC Configuration Software.
Installing the PC Configuration Software
Refer to Table 2 for the equipment needed.
1.Insert the
PC Configuration Software
of the PC. Access the CD and open the
PC Configuration Software
2.Double-click the installation program located in
the folder. Follow the prompts to correctly

Once the Configuration Program is installed on the PC,
the unit can be connected either into the loop or to test
equipment to simulate input and monitor output. With
the PC program, the user can then view and/or change
its operating parameters. To begin the process, connect
the HIM either into the loop (see

to install the instrument into the loop before it is
configured. The secondary method allows you to bench
check the HIM by attaching it to test equipment that
will simulate the input and monitor the output.
Electrical Connections
After mounting, you are ready to connect the HIM to
the loop. Each unit comes equipped with a transmitter
excitation terminal which allows it to supply power to
the monitored HART instrument, if necessary. Figures

connections. To install the HIM into the loop for

the HIM into the loop as shown in Figure 3 (without
using the HIM to power a transmitter) or Figure 4 (using
the TX terminal to power a transmitter). If you need a

The HART protocol allows for two communications
masters on the loop, a Primary and a Secondary.
Setting the HIM to function as the Primary HART
Master in the application means that any other HART
device in the loop must be configured either as a HART
Secondary Master (1 per loop) or as a HART Slave (up
to 16 per loop). Conversely, setting the HIM to function
as the Secondary HART Master allows other HART
devices to function either as a Primary Master or as
slaves. Configuring more than one device on a single
loop as a Primary or Secondary HART Master will
cause a communications failure.
Listen (Specified Slave)
When multiple HART instruments are present, the
Listen (Passive)
returned from one instrument will overwrite the data
previously stored in the HIM. If multiple HART slave
instruments are communicating on the loop, the HIM

will overwrite its internal HART data sets with the latest
device read from the bus, no matter where the data
originates. To allow selective monitoring on a multiinstrument loop, and to allow multiple HIMs to be used
on a digital loop, the
used.
If the HIM is in “Listen” mode it is not a HART communication master and therefore is not in control of
communication. Other HART masters are controlling
the polling of slaves and the HIM can only “Listen”.
The HIM must be able to detect when it has not heard
from its assigned slave device so that it can declare a
“No HART” input and force outputs to the values
specified by the user. The HIM must therefore be told
to wait an appropriate amount of time for the slave
device to send its message before the HIM declares
“No HART”. This timing coordination is accomplished
with

assume that there are five HART transmitters on the

The HIM then sees its slave device speak and waits
seven seconds for it to speak again. As long as the
HIM sees a new message from its slave device its
outputs are updated based upon the measured variables. If the slave device does not speak within the
seven second period, the HIM declares a “No HART”

The HIM’s versatile scaling feature has many possible
applications, as is shown in the illustration below.
Suppose you are using a digital pressure (DP)
transmitter to measure the level of a tank in either
centimeters/inches or PSI. Since the tank is only 300
centimeters (10 feet) high, the full range of the primary
variable (PV) output from the DP transmitter is 0-4.3
PSI. You want to display the full level range (in
centimeters/inches of water) on the HIM. You also
need to control the level from 50% to 100%, since the
tank must be at least 50% full at all times. Finally,
your existing loop indicator and level controller needs
4-20mA to represent 150 to 300 centimeters (60 to 120
inches) of water. How do you do this?

RETURN PROCEDURES
To return equipment to Moore Industries for repair, follow these four steps:
1. Call Moore Industries and request a Returned Material Authorization (RMA) number.
Warranty Repair –
If you are unsure if your unit is still under warranty, we can use the unit’s serial number
to verify the warranty status for you over the phone. Be sure to include the RMA
number on all documentation.
Non-Warranty Repair –
If your unit is out of warranty, be prepared to give us a Purchase Order number when
you call. In most cases, we will be able to quote you the repair costs at that time.
The repair price you are quoted will be a “Not To Exceed” price, which means that the
actual repair costs may be less than the quote. Be sure to include the RMA number on
all documentation.
2.Provide us with the following documentation:
a)A note listing the symptoms that indicate the unit needs repair
b)Complete shipping information for return of the equipment after repair
c)The name and phone number of the person to contact if questions arise at the factory
3.Use sufficient packing material and carefully pack the equipment in a sturdy shipping
container.
4.Ship the equipment to the Moore Industries location nearest you.
The returned equipment will be inspected and tested at the factory. A Moore Industries
representative will contact the person designated on your documentation if more information is
needed. The repaired equipment, or its replacement, will be returned to you in accordance with
the shipping instructions furnished in your documentation.
