PRODUCT
OVERVIEW
AND
PRECAUTIONS
The 375 Field Communicator supports HART and
FOUNDATION fieldbus devices, letting you configure or
troubleshoot in the field. When using the 375 Field
Communicator, follow all standards and procedures
applicable to the location. Failure to comply may result in
equipment damage and/or personal injury. Be sure to
understand and comply with the following items:
375 Field
Communicator
Components
• The 375 Field Communicator includes an FSTN type
LCD with touch-screen display, a Nickel-Metal
Hydride (NiMH) Battery Pack or Lithium Ion (Li-Ion)
Power Module, an SH3 processor, memory
components, and integral communication and
measurement circuitry.
• Three terminals for the lead set are on the top of the
375 Field Communicator. The lead set and terminals
let you connect the 375 Field Communicator to a
device. Each red terminal is a positive connection for
its protocol, while the black terminal is a common
terminal shared by both protocols. An access door
ensures only one pair of terminals is exposed at any
one time. Several markings indicate which pair of
terminals is for which protocol.
• The infrared port and card reader let the 375 Field
Communicator or its System Card interface with a PC.
• Use the keypad or touch screen to enter data into the
375 Field Communicator.
Learning the Basics

• An Expansion Module, labeled Expansion Module, is
a removable memory card that snaps into the
Expansion Port.
• Only the Expansion Module or Expansion Port Plug
should be inserted into the Expansion Port. System
Cards/Secure Digital cards or other objects must not
be put into the Expansion Port. Failure to comply will
void the IS approval and the warranty.
• The System Card used in the System Port must be
supplied by the 375 Field Communicator
manufacturer. Failure to comply will void the IS
approval and the warranty.
Working in an
Intrinsically
Safe (IS) Area
• An IS-approved 375 Field Communicator can be used
in Zone 0 (FM and CSA only), Zone 1, or Zone 2,
Division 1 and Division 2 locations (KL option only).
• An IS-approved 375 Field Communicator may be
connected to loops or segments that are attached to
equipment located in Zone 0, Zone 1, Zone 2, Zone
20, Zone 21, Zone 22, Division 1 and Division 2 (KL
option only).
• The battery can be installed or removed in an
Intrinsically Safe area; however, it cannot be charged.
• The Expansion Module can be removed or installed in
a hazardous area.
• The Expansion Module can be installed in an
Intrinsically Safe area while the 375 Field
Communicator is still running.

BATTERY AND
POWER
SUPPLY/
CHARGER
OVERVIEW
The 375 Field Communicator supports two types of
batteries: the NiMH Battery Pack and the Li-Ion Power
Module. The NiMH Battery Pack has a black, 4-pin
power supply/charger connector and the Li-Ion Power
Module has a green, 6-pin connector. See Figure 2-3 on
page 2-11 for the location of the connector. The label on
the back of the battery also identifies the type.
NOTE
The term “battery” is used to describe functionality
common to both types of supported batteries. Any
differences are noted.
Guidelines and
Precautions
Before using the battery or power supply/charger
(00375-0003-0005), understand and follow the
guidelines below:
• When transporting a Li-Ion Power Module, follow all
applicable regulations.
• Use the power supply/charger with the 375 Field
Communicator only. Use only the supported power
supply/charger to charge the battery. Failure to
comply may permanently damage your 375 Field
Communicator and will void the IS approval and the
warranty.
• Protect the battery and power supply/charger from
moisture.
• Do not cover the battery or power supply/charger,
subject it to direct sunlight, or place it on or next to
heat-sensitive materials.
• Do not open or modify the battery or power
supply/charger. There are no user-serviceable
components or safety elements inside. Opening or
modifying them will void the warranty.
Learning the Basics
Check the
Charge
Remaining
2-5
Use the Power Status option in the Settings menu or the
lights on the battery to view the remaining charge. See
“Power Status” on page 2-18 for details.
To check the remaining charge from the lights on the
battery:
1. Remove the battery if it is connected to the 375 Field
Communicator. See “Removing the Battery and the
System Card” on page 2-9 for the procedure.
2. Turn the battery over, and press the charge indicator
button located on the lower left side. The lights
illuminate based on the amount of charge remaining.
Each light represents 20 percent of the charge
remaining. The battery is fully charged when all of the
lights are illuminated.
Charge the
Battery
CAUTION
The previous 4-pin power supply/charger is incompatible
with the 6-pin Li-Ion Power Module.
Prior to first portable use, fully charge the battery. The
battery can be charged separately or while attached to
the 375 Field Communicator. The 375 is fully operable
when the battery is recharging. The power
supply/charger can remain connected after the battery is
fully charged. An overcharge condition will not occur.
The power supply/charger is compatible with both types
of batteries. However, the NiMH Adapter Cable must be
used with the power supply/charger to charge the NiMH
Battery Pack. See Figure 2-1. The connector on the
power supply/charger is green to match the appropriate
connector on the Li-Ion Power Module or the NiMH
Adapter Cable.

Maintaining
the Battery
Life and
Performance
2-7
To maintain the battery life and performance, understand
and follow the guidelines below:
Li-Ion Power Modules
• Recharge the Power Module frequently, preferably
after each use or at night. It is recommended to limit
the number of full discharge and recharge cycles.
• Frequent use at high temperatures can reduce
performance.
• Use a dry location at or near room temperature when
storing the Power Module for an extended time.
Prolonged storage at higher temperatures can reduce
performance.
• Ensure the remaining charge level is at or near
mid-capacity when storing for an extended time. The
remaining charge will slowly drain during storage.
Periodically charge the Power Module to ensure the
remaining charge does not drain to low levels.
NiMH Battery Packs
• Recharge the Battery Pack when it is nearly
discharged. NiMH Battery Packs benefit from full
discharge and recharge cycles.
• Use a dry, cool location when storing the Battery Pack
for an extended time.
• Ensure the remaining charge level is nearly full when
storing the Battery Pack. The remaining charge will
slowly drain during storage. Periodically charge the
Battery Pack to ensure the remaining charge does not
drain to low levels.

Free Memory
on a System
Card
Learning the Basics
When you add new device descriptions and system
software to your 375 Field Communicator, more space
on your System Card is used. Over time, your System
Card will become full and there will not be enough
memory to add new files.
You can use the System Card Memory Management
feature in the Easy Upgrade Programming Utility to free
space on your System Card. This feature lets you select
which device descriptions can be downloaded. Reducing
the number of DDs on a System Card can save a
significant amount of space. For example, if your site

diagnostic routine at the device and can report an
electronics failure, as well as other failures that can
affect performance.
HART Functionality
3-13
Loop test is used to set the output of the device at a
specified analog value, and may be used to test the
integrity of the loop and the operation of indicators,
recorders, or similar devices in the loop.
Calibration is used to perform such operations as
performing a sensor trim, D/A trim, and scaled D/A trim.
Basic setup
The Basic setup menu provides quick access to a
number of configurable parameters including tag, unit,
range values, and damping.
The options available in the Basic setup menu are the
most fundamental tasks that can be performed with a
device. These tasks are a subset of the options available
under the Detailed setup menu.
The Tag alphanumeric identifies a specific device.
Changing the unit option affects the engineering units
that are displayed. Changing range values changes the
analog output scaling. Changing damping affects the
response time of the transmitter and is often used to
smooth the output when there are rapid input variations.

SECTION 4
FIELDBUS FUNCTIONALITY
OVERVIEW
This section provides instruction on basic fieldbus
functionality in the 375 Field Communicator. It is based
on the operation of the FOUNDATION Fieldbus Application
version 5.0.
SAFETY
MESSAGES
Procedures and instructions in this section may require
special precautions to ensure the safety of the personnel
performing the operation. Information that raises
potential safety issues is indicated by a warning symbol
(
). Refer to the following safety messages before
performing an operation preceded by this symbol. Other
warning messages can be found in the Troubleshooting
section of this manual.
WARNING
If a segment is connected to a host system, the changes made with the 375 Field Communicator
may not be recorded in the host system’s permanent database. Verify the changes in the
database. Otherwise, this could cause unpredictable results and, depending upon your
application, process disruption leading to property damage, serious injury, or death. Ensure all
safety precautions and work procedures have been followed.
WARNING
Changing device parameters could adversely affect the control of your process. Put the control
loop in Manual/Out of Service before applying changes. Verify the output before returning the
control loop to Auto. Failure to do so could result in property damage, serious injury, or death.
Ensure all safety precautions and work procedures have been followed.

WARNING
The 375 Field Communicator draws approximately 17 mA from the fieldbus segment. Be sure
the power supply or barrier on the fieldbus segment has the capacity to provide this additional
current. If a heavily loaded fieldbus segment is drawing near the capacity of the segment’s
power supply, connecting the 375 Field Communicator may result in loss of communication.
BASIC
FEATURES
AND
FUNCTIONS
Link Active
Scheduler
(LAS)
All segments have only one Link Active Scheduler
(LAS). The LAS operates as the bus arbiter for the
segment. The 375 Field Communicator is set up to
always be the last node to become the LAS on a
segment.
The devices that are capable of becoming the LAS are
called link master devices. All other devices are referred
to as basic devices. When a segment first starts up, or
upon failure of the existing LAS, the link master devices
on the segment bid to become the LAS. The link master
that wins the bid (the one with the lowest address)
begins operating as the LAS immediately upon
completion of the bidding process. Link masters that do
not become the LAS can act as LAS backups by
monitoring the segment for failure of the LAS and then
bidding to become the LAS when a LAS failure is
detected.
Although the 375 Field Communicator is capable of
becoming the LAS, it does not maintain the
communication schedule and should not be thought of
as a backup LAS.
Only one device can communicate at a time. Permission
to communicate on the bus is controlled by a centralized
token passed between devices by the LAS. Only the
device with the token can communicate. The LAS
maintains a list of all devices that need access to the
bus. This list is called the Live Device List; see
“Displaying the Live Device List” on page 4-9.
Fieldbus Functionality
LAS Hierarchy
4-3
When a 375 Field Communicator is connected to a live
fieldbus segment, it joins the fieldbus segment but not as
the LAS. This means the 375 Field Communicator can
view and edit device parameters, but the control of the
segment is still handled by the node that is designated
the LAS for the segment. You can also read and write if
there is another LAS. Prior to connecting to a host
system, review the 375 Field Communicator Host
System Interoperability on www.fieldcommunicator.com.
Device
The 375 Field Communicator is designed to operate with
Interoperability a wide range of FOUNDATION fieldbus devices
independent of device manufacturer. Device
interoperability is achieved through the use of Device
Description Language (DDL) technology supported by
the Fieldbus Foundation.
Basic testing is performed on all device descriptions. In
addition, each device manufacturer is asked to certify
that they have thoroughly tested their devices with the
375 Field Communicator. If certification is not received, a
warning message will display when you attempt to
access an untested device.
ST_REV
ST_REV is a block parameter that increments each time
a block configuration has changed. While a list of
parameters is displayed, the 375 Field Communicator
continuously reads the ST_REV of that particular block.
If it sees the ST_REV counter has incremented, it knows
that there has been a change to the block, and it
automatically refreshes (rereads) all of the block
parameters. Thus, there would only be a very short
period of time before a change made by another host
would appear on the 375 Field Communicator display.

STARTING
THE
FIELDBUS
APPLICATION
A general warning message may appear upon starting
the Fieldbus Application when an LAS is detected on the
segment. Select YES to go to the Live Device List, NO to
return to the 375 Main Menu, or HELP to get more
information on the warning.
To start the Fieldbus Application:
1. Turn on the 375 Field Communicator. The 375 Main
Menu is displayed.
2. Double-tap FOUNDATION Fieldbus Application from
the 375 Main Menu. If a live fieldbus device is
connected to the 375 Field Communicator, the
Fieldbus Application main menu will briefly display
followed by the Live Device List. Figure 4-1 shows the
Fieldbus Application main menu.
If insufficient voltage is detected, a warning message
appears. Press OK to go to the Fieldbus Application
main menu.
Figure 4-1. Fieldbus Application main menu screen
A connection warning message may appear if no
communication is detected. This means that a LAS is not
recognized by the 375 Field Communicator. This
typically occurs when connecting to a single device.
To go back to the 375 Main Menu, press the back arrow
button. From the Fieldbus Application main menu, you
can choose Online, Utility, or Fieldbus Diagnostic
functions. The rest of this section guides you through the
Fieldbus Application menus and functions.

The online menus display data for the device to which
you are connected. The online menus display critical,
up-to-date process information, including the segment
Live Device List, Block Lists, device menus, and
parameter functionality.
NOTE
It is normal for processes to take longer the greater the
amount of scheduled communication. This is influenced
by the number of devices and the control methods in
place.
Connecting to
a Fieldbus
Segment
Connect the 375 Field Communicator with the
appropriate connectors in parallel with the device. Due to
measurement circuitry, the 375 Field Communicator
fieldbus connections are polarity sensitive. An error
message displays if the device is connected incorrectly.
For information about intrinsically safe connections, see
Appendix B.
NOTE
Dynamic variables shown while online represent the
digital data being sent from the device.
Digital communication is susceptible to electrical noise;
follow proper wiring instructions.
Fieldbus Functionality
4-6
Three terminals for the lead set are on the top of the 375
Field Communicator. The lead set and terminals let you
connect the 375 Field Communicator to a device. Each
red terminal is a positive connection for its protocol. The
black terminal is a common terminal shared by both
protocols. An access door ensures only one pair of
terminals is exposed at any one time; see Figure 4-2.
Several markings indicate which pair of terminals is for
which protocol.

Fieldbus Functionality
Modes
4-11
The resource, transducer, and all function blocks in the
device have modes of operation. These modes govern
the operation of the block. Every block supports both
automatic (AUTO) and out of service (OOS) modes.
Other modes may also be supported.
Types of Modes
For the procedures described in this manual, it is helpful
to understand the following modes:
AUTO
The functions performed by the block will
execute. If the block has any outputs, these will
continue to update. This is typically the normal
operating mode.
MAN
In this mode, the output of the block can be
manually overwritten for testing purposes.
Out of Service (OOS)
The functions performed by the block will not
execute. If the block has any outputs, these will
typically not update and the status of any values
passed to other blocks will be “BAD”. Before you
make changes to the configuration of the block,
change the mode of the block to OOS. When the
changes are complete, change the mode back to
AUTO.
Other Types of Modes
Other types of modes are Cas, RCas, ROut, IMan and
LO. For more information, see the Emerson Process
Management, Rosemount Division Function Block
manual, document 00809-0100-4783.
Fieldbus Functionality
4-12
Mode Parameters
Mode parameters are used to change the block mode
from one state to another. There are four types of mode
parameters: Target, Actual, Permitted, and Normal.
The Target mode is the mode that was assigned to a
block and is used to change a block to a desired mode.
The Actual mode is the current mode of the block.
The Permitted mode lists the modes that are allowed for
a block. Setting the Permitted modes prevents
unauthorized changes to the operating mode of a block.
To do this, configure the Block:Mode Permitted
parameter to allow only the desired operating modes. It
is recommended to always select OOS as one of the
Permitted modes.
The Normal mode is the mode the block should be set to
during normal operation conditions. Only the Permitted
modes are displayed.
Locate Mode Parameters
In the resource and transducer blocks, the mode
parameters are normally found in the Process menu. In
all other function blocks, they are found in the Common
Config menu. The mode parameters will also be
included in the All parameter list; see “Working with
Device Blocks” on page 4-14.
You can view and edit the Target mode parameter by
tapping the MODE button in the menus.
Fieldbus Functionality
4-13
Change Modes
Whenever you need to change the parameters or
properties of a block, you need to change the mode. A
warning message may appear whenever the mode of
any block is included in a list of parameter changes to be
sent to a device.
To change the block mode:
1. Tap the MODE button in the Block Menu or device
menu.
2. If prompted, select a block from the list and tap OK.
3. Uncheck the current mode. An asterisk (*) symbol
appears next to Block Mode: Target to indicate a
change has been made to the Target mode. If the
mode checkboxes are read-only, the block may have
been set to allow only one mode.
4. Tap the checkbox next to a mode to select it as the
new Target mode. A checkmark appears.
5. Tap OK.
6. When the warning message appears, thoroughly read
it and tap YES to send the change to the device, or
tap NO to cancel the operation. A Mode Change
screen showing the Target mode and Actual mode are
displayed until the Actual mode is updated. Tap
CLOSE to close the Mode Change screen.

noise level test will not display this status indicator.
Error - There is an error in the measurement or within
the 375 Field Communicator.
Signal Level
Measurement
The signal level test determines if a 375 Field
Communicator can receive signals from devices on a
segment. To measure the fieldbus signal level, make
sure an LAS is on the segment. Up to 16 different
devices are checked. The word Limit is displayed if the
signal level value is greater than 1.3 V.

This test displays the device address, measurement
value, measurement unit, and one of the status
indicators listed below.
- All signal responses from the device were
received by the 375 Field Communicator.
! - Some signal responses from the device were
received by the 375 Field Communicator. Signal
responses may be missed due to noise on the
segment.
X - No signal responses from the device were
received by the 375 Field Communicator. This may be
caused by noise on the segment.
Error - The measurement value is less than 75 mV or
there is an error within the 375 Field Communicator.

TROUBLESHOOTING
OVERVIEW
This section provides basic troubleshooting techniques
for the 375 Field Communicator.
Below are methods for troubleshooting networks that are
experiencing problems communicating between a field
device and the 375 Field Communicator.
Troubleshooting Answer the questions below and use the troubleshooting
tables in this section before calling Technical Support
Suggestions
personnel.
• Does the control system have HART or fieldbus
communication capabilities?
• Is it configured to communicate HART or fieldbus
currently? Is it reporting communication problems? If
not, stop communications on the control system and
re-test communication with the 375 Field
Communicator.
• Is there a barrier installed?
• Is the barrier capable of passing along the signal?

Troubleshooting

HART Loops
Verify the HART loop current and voltage on the field
device. Almost all field devices need at least 4 mA and
12V DC to operate properly.
If there are multiple field devices on a multidrop loop, set
the 375 Field Communicator to Poll by Address. See
“Changing the HART Polling Option” on page 3-17 for
more information on polling options.
Inspecting the loop wiring can often reveal problems.
The shield is normally grounded at one end only, which
is usually the control system.
Verify the loop has a minimum of 250 ohms resistance. If
there is not an external resistor, then, normally, the total
resistance is the resistance of the process-indicating
device monitoring the loop. Check the manuals for the
process-indicating device to determine its loop
resistance. If the resistance of the process-indicating
device is unknown, it can be determined by knowing the
current flow in the loop and the voltage across the
process-indicating device.
The resistance can be calculated using the formula,
Resistance = Voltage / Current. The 375 Field
Communicator can be used to measure the voltage; see
“DC Voltage Measurement (HART Terminals)” on
page 3-22.
Troubleshooting
5-3
Sample values
Loop Current Flow Minimum voltage for 250 ohms.
4 mA 1 Volt
8 mA 2 Volts
12 mA 3 Volts
16 mA 4 Volts
20 mA 5 Volts
If the voltage across the process-indicating device is
greater than the value listed for a given current flow, the
device has at least 250 ohms of internal resistance. If
the voltage is less than the value listed in the table for
the given current flow, more resistance needs to be
added to the loop.
If an oscilloscope is available, use it to look for noise on
the loop. Use a scope with differential mode capability or
a battery powered/isolated scope to avoid grounding one
side of the loop. Noise with a frequency of 500 Hz to
10,000 Hz is of particular interest, as this represents
frequencies near the HART frequencies of 1200 and
2200 Hz.
