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 transmit-
ter 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 informa-
tion 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 condi-
tions 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 trans-
mitters 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 inter-
face with every HART-compatible monitoring and con-
trol device.

Table 2. Assembling the Necessary Equipment
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 communi-
cates with the PC through a proprietary communica-
tions 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
Moore Industries Interface Solution
PC Configuration Software
CD into the CD drive
of the PC. Access the CD and open the
HIM
PC Configuration Software
folder.
2. Double-click the installation program located in
the folder. Follow the prompts to correctly
install the program.
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
Installing the HIM into
the Loop
) or into a configuration setup (see
Bench
Checking the HIM
).

HIM
Smart HARTLoop
Interface and Monitor
Installing the HIM
There are two methods for connecting the HIM for
configuration. The recommended method requires you
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.
Installing the HIM into the Loop
Installation consists of physically mounting the unit,
grounding the instrument, and completing the electrical
connections. To install the HIM into the loop for
configuration, use the equipment in Table 2 to hookup
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
complete terminal description, refer to Table 1.
Mounting
The HIM is designed to snap easily onto 32mm, G-type
(EN50035) or 35mm Top Hat (EN50022) DIN rails.
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
2 and 3 show the connection diagrams for an HIM with
or without using the transmitter excitation current.
CE Conformity
Installation of any Moore Industries products that carry
the CE certification (Commission Electrotechnique)
must
adhere to the guidelines in
Installing the HIM
in
order to meet the requirements set forth in applicable

factory for the most current information on products
that have been CE certified.
Recommended Ground Wiring Practices
Moore Industries recommends the following ground
wiring practices:
• Any Moore Industries product in a metal
case or housing should be grounded.
• The protective earth conductor must be
connected to a system safety earth ground
before making any other connections.
• All input signals to, and output signals
from, Moore Industries’ products should be
wired using a shielded, twisted pair
technique. Shields are to be connected to an
earth or safety ground at the unit itself.
• The maximum length of unshielded input
and output signal wiring should be 2 inches.
Power Sourcing Parameters for General
Locations, Intrinsically Safe, and
Non-Incendive/Type N applications
In accordance with IEC 1010.1 Annex H
(all models), the input terminals must be
connected to and/or supplied from a certified
energy limiting Class 2 or a Separate Extra Low
Voltage (S.E.L.V.) power supply separated from
all mains by double/reinforced insulation.

HART Parameters
To program the HART parameters, change the settings
in the
Communications Settings
box, then press
Quick
Set
. See the descriptions below of the various
sections of the screen.
HART Address
The
HART Address
is the address of the HART device
that the HIM will be monitoring.
Number of Retries
The
Number of Retries
can be set between 1 and 9,
and will determine how many times the HIM will
attempt to poll the HART transmitter (without success),
before it indicates a HART Fault condition.
Normal/Burst/Listen (Passive) Modes
The HIM can operate in one of four modes:
Normal
,
Burst
, or
Listen (Passive)
and
Listen (Specified Slave)
.
In each of these modes, the HIM attempts to find a
HART transmitter.
In
Normal
mode, the HIM polls the HART loop for a
transmitter, then polls the HART instrument twice per
second, requesting the current process status and the
HART instrument’s diagnostic status. The HART
instrument responds with the requested data.
In
Burst
mode, the monitored HART instrument is
programmed to continuously transmit its process
variable and health status. The HIM samples the
continuous HART data three times per second.
Listen (Passive)
mode allows the HIM to operate on a
loop that already has primary and secondary HART
masters. In
Listen
(Passive)
mode, the monitor
connects passively, continuously sampling HART data
from a smart instrument without affecting normal loop
operation. When using this mode, either the monitored
smart HART instrument must be set in
Burst Mode
or a
HART master must be continuously polling the smart
HART slave device.
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)
mode cannot be used because data
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 multi-
instrument loop, and to allow multiple HIMs to be used
on a digital loop, the
Listen (Specified Slave)
feature is
used.
If the HIM is in “Listen” mode it is not a HART commu-
nication 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
Timeout Period
.
Timeout Period
is a value between 1 and 30sec and
must be greater than the period between polls by the
HART master of the Specified Slave. For example,
assume that there are five HART transmitters on the
same multi-drop loop as the HIM. The HART master is
configured to poll each device every second. It then
takes the HART master five seconds to repeat the poll
to the one device being monitored by the HIM. the HIM
Timeout Period
must be set at a value greater than five

HIM
12 The Interface Solution Experts

Interface and Monitor
seconds. In this example, we will use seven seconds.
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 vari-
ables. If the slave device does not speak within the
seven second period, the HIM declares a “No HART”
situation and sends its outputs to the failed communi-
cations values.
To use this feature, proceed with the following steps:
1. Select the
Listen (Specified Slave)
button.
2. Enter your desired value into the
Timeout Period(s)
text box.
Factory default is 5 seconds. The maximum Timeout
Period is 30 seconds.
3. Set the exact slave address of the instrument you
wish to monitor. Click the
Set Slave Address
button.
This brings up the
HART Slave Device Long Format
Address Settings
screen (Figure 8). Enter the required
information into the appropriate text boxes.
The
Manufacturer’s ID
and
Device Type ID
for the
instrument that the HIM will listen to are available from
the HART Foundation website at www.hartcomm.org
and/or the instrument manufacturer.
Values obtained from the HART website are in HEX
code. The HIM does not use HEX code; you must
convert this value to Decimal code.
Figure 8. HART Slave Device Long Format Address Settings
Screen
To convert HEX to Decimal code, perform the
following steps:
Access the Calculator feature in Microsoft
Windows® by opening the
Start
menu. Next,
select
Programs
then
Accessories
and finally
Calculator
.
Ensure that the Calculator is in
Scientific
mode.
To do this, select the
View
dropdown menu
and choose
Scientific
.
Click the
Hex
radio button and enter the HEX
code value.
Next, click the
Dec
button and the value will be
converted into the Decimal value.
Enter the converted value into the proper param
eter.
The
Device ID Number
is the serial number of
the exact device to which the HIM will listen.

Alarms Parameters
The Alarms tab controls the programmable alarm
trip(s) option. This screen will be grayed out if the
attached HIM is not equipped with at least one alarm
trip. To program the Alarm parameters, change the
settings in the
Alarm1
and/or
Alarm2
box, then press
Quick Set
. The sections of the screen are described
below.
Trip/Fault Alarms
A
Trip Alarm
monitors a selected variable and trips
either when the variable exceeds a set value (Trip
High) or when the variable falls below a selected value
(Trip Low). The
Source
specifies which variable will be
monitored, while the
Trip Point
sets the point at which
the alarm will trip. After the alarm trips, the
Dead
Band
determines how far past the trip point the
variable will have to go before the alarm condition
returns to normal.
There are two types of Fault Alarms. A
HIM Fault
Alarm
monitors the health of the HART monitor. It will
trip whenever the internal error status word is set. For
example, if the HIM’s configuration file becomes
corrupt, this alarm will trip and the monitor will display
BAD_CONFIG. A
Field Device Fault Alarm
monitors
the health of the HART transmitter. This fault alarm
will trip for any of these eight malfunctions:
Figure 10. Alarms Tab
Device Malfunction (Bit 7)
Relay trips whenever it detects that a hardware error or
failure has occurred in the connected HART device.
Configuration Changed (Bit 6)
Relay trips whenever it detects that the connected
HART device has had its configuration changed.
Cold Start (Bit 5)
Relay trips whenever the power to the HART device is
interrupted. It will also trip during a HART Master
Reset or Self Test Command.
Additional Status (Bit 4)
Relay trips whenever the connected HART device
reports a condition requiring HART Command #48,
which is Read Additional Information. This indicates
that the instrument needs attention from a device with
full HART command capability.
Output Current Fixed (Bit 3)
Relay trips whenever the HIM detects that the
connected HART device’s output is no longer
responding to changes in its input, and is being held at
a predefined level.
PV Analog Output Saturated (Bit 2)
Relay trips whenever it detects that both its analog and
digital representations of the Primary Variable are
outside rated operating limits, and no longer reflect the
true sensor input.
Non-PV Out of Limits (Bit 1)
Relay trips whenever one of the HART ancillary
variables (second, third or fourth), is operating outside
the limits that can be effectively measured.
PV Out of Limits (Bit 0)
Relay trips whenever the HART Primary Variable is
operating outside the limits that can be effectively
measured.
Delay & Fail Safe
By entering a value in the
Delay
box, you can specify
how long (in seconds) the alarm condition needs to
exist before the alarm trips.
Failsafe
alarms (box
checked) de-energize when in alarm condition;
Non-Failsafe
alarms energize when tripped.

HART Additional Status Alarm Bits
HART Additional Status also called “More Status” and
“Command 48” is where device manufacturers install
the custom diagnostics for the specific device. For
your particular application, you may choose all of these
diagnostics to cause the HIM relay to trip or just one
diagnostic bit to trip the HIM relay (or any combination
in between). The manufacturer of the HART device will
be the source for the specific diagnostic information.
Selecting the
Field Device Fault Alarm
function in the
Alarms
screen allows you to enable the HIM to set
alarm states, when in fault mode, based on the bit
settings of the additional status information returned by
certain HART instruments. This provides flexibility to
the requirement of alarming on additional status infor-
mation.
Choosing this feature, you are given the ability to
specify the bit(s) on which to alarm. To access this
feature, check the
Additional Status
box. The
Edit
button will appear in the
HART Additional Status Bits
section of the screen. Clicking the
Edit
box brings up
the
Additional HART Status Alarm Bits Settings
window
(Figure 11). Check the box(es) that correspond to the
bits you wish to use; click
OK
.
Download the information to your instrument once you
are finished.

Analog Outputs Parameters
The HIM comes with either two (–2AO) or three (–3AO)
analog outputs. The
Analog Outputs
tab allows you to
specify which HART variable is to be monitored as the
source of the analog output, the input range and output
range, and how the output will react when the variable
input is out of range. To program the Analog Outputs
parameters, change the settings in the
Output1/2/3
boxes, then press
Quick Set
. See the descriptions
below of the various sections of the screen.
Source
Source
defines the variable that the analog output will
monitor. Notice that selecting one of the scaled
outputs will require you to make changes to the
Scaling
tab, and selecting the Custom Curve option will
require you to make changes to the
Custom Curve
tab.
Input/Output Range
The
Input
or
Output Range
defines the range of the
source input and the range of the analog output.
These two sets of fields can be used to scale the
HIM’s output.
Figure 12. Analog Outputs Tab
For example, you have a vortex flow meter with an
imbedded RTD that measures the process
temperature, and that temperature is assigned to the
HART Secondary Variable. The full range of the RTD
sensor is from –400°F to +1760°F, but your flow
stream will always be between 0° and 400°F. To scale
the analog output, for Output 1, set the
Source
as SV.
Set the
Input Range
to 0° and 400°F, and the
Output
Range
to 4mA to 20mA. Click
Quick Set
to download
the new configuration file to the HIM.
Output Current Box
The
Output Current
Box on the
Analog Outputs
Tab
displays up-to-the-second information on the value, in
mA, of the analog output.
Fail Mode
The
Fail Mode
setting determines how the HIM will
respond when its monitored input fails. If
Fail Mode
is
set to
High
and the measured input goes out of range,
or any detected error occurs in the HART transmitter,
the analog output will output a 23.6mA signal. If Fail
Mode is set to
Low
and the measured input goes out of
range, or any detected error occurs in the HART
transmitter, the analog output will output a signal that
is 90% of the lower range value below 4mA; it will
output 0mA if the lower range is set to 0mA.
If
Fail Mode
is set to
Hold Last
, the HIM will continue
to output the last value it recorded before the input
failed. If
Fail Mode
is set to
Hold Last Then High
or
Hold Last Then Low
, the HIM will continue to output the
last value recorded for a set amount of time (according
to Hold Last Duration box), then either fail high or fail
low, respectively.
Quick Set Button
The
Quick Set
button causes the software to configure
the instrument’s analog output settings to match those
currently entered in the PC Software.
Trim Button
The
Trim
button brings up the Trim Menu, allowing you
to set the device’s output to match the reading of the
loop. Refer to the

Configuring Analog Output Trimming
The
Analog Output Trimming
section of the software
allows you to match the HART monitors analog output
to the output measured by a calibration device. This
will require a calibrated multimeter, such as a HP Model
3478A or equivalent, accurate to ±0.009%.
Note:
Trimming the analog output of the monitor
nullifies any scaling that may have been
performed in the
Scaling
tab.

Scaling Parameters
The
Scaling
tab allows you to configure the values for
scaled variables. To scale the selected variable, enter
the values into the appropriate boxes, then click on the
Transfer
menu and click
Download
to transfer the new
scaled values to the HIM. (If any scaled variable was
selected in the
Display, Alarm or Analog Outputs
tabs,
then the corresponding scaled variable section will
become active for editing).
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?
Scaling Illustration
1. Since you want to display the full level range in
inches of water (in H2O) on the HIM, and the HIM is
reading PSI as the primary variable, first go to the
Display
tab and select
Scaled PV
as your display
source.
2. Go to the
Scaling
tab and set up the
PV Zero
and
PV Full
values, and the
Scaled PV Zero
and
Full
values.
PV Zero
would be 0 (PSI) and
PV Full
would
be 4.3 (PSI).
Scaled PV
would correlate to zero being
0 in H2O and full being 120 in H2O. The HIM should
now (after downloading) display the full range in
in H
2
O
.
3. To manipulate the HIM’s analog output, go to the
Analog Outputs
tab. Select
Scaled PV
as the Output 1
source. Since you need to control the level from 50%
to 100%, the
Input Range
should be 60 to 120 in H2O
and the
Output Range
should be 4mA to 20mA.
