Smart HARTLoop
Interface and Monitor
Introduction
This is the user’s manual for the Moore Industries HIM
Smart HART® Loop Interface and Monitor. It contains
all of the information needed to configure, install, oper-
ate and maintain this instrument.
About this Manual
Pay particular attention wherever you see a “Note”,
“Caution” or “WARNING ”.
Note– Information that is helpful for a procedure, con-
dition or operation of the unit.
Caution– Hazardous procedure or condition that
could damage or destroy the unit.
WARNING– Hazardous procedure or condition that
could injure the operator.
The HIM
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
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.
The HIM allows you to leave existing smart HART
transmitters and valves in place, yet still take
advantage of all the information they have to offer.
Model and Serial Numbers
Moore Industries uses the model and serial numbers
of our instruments to track information on each unit
that we sell and service. If a problem occurs with your
HIM, check for a tag affixed to the unit listing these
numbers. Supply the Customer Support
representative with this information when calling.
Inputs
The HIM accepts a HART digital protocol input directly
from a smart HARTmultivariable temperature, pres-
sure, level, flow transmitter or from a valve positioner.
Outputs
The HIM can be ordered with the following outputs.
2AO / 3AO
With this output, the HIM comes equipped with either
two (2AO) or three (3AO) programmable analog output
channels.

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 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 into the loop (see Installing the HIM
into the Loop) or into a configuration setup (see Bench
Checking the HIM).

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
To install the HIM into the loop for configuration, use
the equipment shown in Table 2. Refer to Figure 5 (to
install without using the TX power supply) or Figure 6
(to install using the TX power supply).
Bench Checking the HIM
If you would like to configure the HIM before attaching
it to the loop, you need to hook it up with the
equipment listed in Table 1. Refer to Figures 3 and 4
for instructions on how to bench check the HIM either
with or without taking advantage of the Transmitter
Excitation (+TX) terminal. If you need further
descriptions of the terminals, see Table 2.

The HIM PC Configuration Software can be used to
program all of the HIM’s parameters. Once the default
configuration has been saved, it is safe to program
other parameters. The PC Software is made up of
these sections:
1. HIM Status and Information Section–The left
side of the screen includes seven boxes that display
the different settings of the attached HIM.
Program Status–Displays the activity of the
connected HIM. It will show you if the unit is Idle,
Uploading, Downloading, Monitoring or Searching.
HIM Device Info–Displays the individual charac
teristics of the attached HIM, such as its Identifi-
cation, Hardware and Software Revisions, and the
last date that the device was configured.
HIM Tag–A phrase used to identify a HIM.
Figure 8. HIM PC Configuration Software Screen
HIM Device Status–Displays how the HIM is
functioning, giving a brief summary of any errors or
displaying OK if it is operating normally.
HIM Displayed Data–this display mirrors what the
attached HIM is displaying.
Progress–This bar stays in motion any time the HIM
is monitoring, uploading or downloading.
Communication Status–monitors the PC Software’s
ability to communicate with the HIM.
2. HART/Display/ Alarms/Analog Outputs/Custom
Curve/ Scaling/MODBUS Tabs–These tabs change
the right side of the screen to allow you to set the
appropriate part of the HIM’s configuration. Refer to
the associated pages in this document for additional
information on these tabs.
3. Menu Bar/Tool Bar– Dropdown menus and
corresponding icons allow you to perform various
functions throughout the PC Configuration Program.

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 com-
munication 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 3 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.

HIM
16 The Interface Solution Experts
Smart HARTLoop
Interface and Monitor
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 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
variables. 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 9. 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.
4. Once complete, press OK.
Download the information to your instrument once you
are finished.
Auto Clear Status Bit
Most HART instruments indicate when a device’s
configuration has been changed. This indication
(status bit) can be reset by sending HART command
38–reset configuration changed. Checking the
Auto Clear Status Bit box causes the HIM to issue
this command whenever the HART instrument it is
monitoring has its configuration changed. However,
the HIM can also be set to alarm on this bit (see
Programming the Alarm Parameters). If the HIM is
both set to alarm and to auto clear, then it will do both–
going into alarm mode and resetting that indication.
Quick Read/Set
The Quick Read button causes the PC Configuration
Software to read the communications information
from the attached HIM; the Quick Set button causes
the software to configure the HIM’s communications
settings to match those of the PC Software.

Alarms Tab
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:
Device Malfunction (Bit 7)
Figure 11. Alarms Tab
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 (Secondary, Tertiary, or Quaternary), are
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
information.
Choosing this feature, you are given the ability to spec-
ify 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 Addi-
tional HART Status Alarm Bits Settings window (Figure
11). Check the box(es) that correspond to the bits you
wish to use; click OK.
