This manual only describes how to install and use the
XM-120 Eccentricity module. For information about the
dynamic measurement and low frequency dynamic
measurement modules, refer to the XM-120/121 Dynamic
Measurement Module User’s Guide.
The XM-120 Eccentricity module is a 2-channel eccentricity monitor. It is a
member of the Entek XM® Series, a family of DIN rail mounted condition
monitoring and protection modules that operate both in stand-alone
applications or integrate with Programmable Logic Controllers (PLCs) and
control system networks.
Eccentricity is the measure of the amount of bow in a rotor. The lower the
eccentricity value the more straight the shaft. Rotor bow can be a fixed
mechanical bow, or it can be a temporary bow caused by uneven thermal
heating or simply by the weight of the rotor (gravity bow).
The Eccentricity module is suitable for virtually all types of rotating and
reciprocating machinery where rotor bow must be measured prior to or during
startup. It accepts input from non-contact eddy current probe systems to
provide peak-to-peak eccentricity, maximum instantaneous DC voltage (max
gap), minimum instantaneous DC voltage (min gap), and instantaneous DC
voltage (gap) measurements. In addition to the transducer inputs, the module
can accept one tachometer input to provide speed measurement, which can, if
desired, be used to disable eccentricity alarms after startup.

Introduction
The Eccentricity module includes a single on-board relay, expandable to five,
making it a complete monitoring system. It can operate stand-alone, or it can
be deployed on a standard or dedicated DeviceNet network where it can
provide real-time data and status information to other XM modules, PLCs,
distributed control systems (DCS), and Condition Monitoring Systems.
The Eccentricity module can be configured remotely via the DeviceNet
network, or locally using a serial connection to a PC or laptop. Refer to
Chapter 3 for a list of the configuration parameters.

mounted base unit that provides terminations for all field wiring
required by XM Dynamic Measurement and Eccentricity modules.
• XM-120 Dynamic Measurement Module - The XM-120 mounts on the
XM-940 terminal base via a keyswitch and a 96-pin connector. The
XM-120 contains the measurement electronics, processors, relay, and
serial interface port for local configuration.
IMPORTANT
The XM-441 Expansion Relay module may be connected
to the XM-120 module via the XM-940 terminal base.
When connected to the module, the Expansion Relay
module simply “expands” the capability of the XM-120 by
adding four additional epoxy-sealed relays. The module
controls the Expansion Relay module by extending to it the
same logic and functional controls as the on-board relay.

Grounding Requirements
Use these grounding requirements to ensure safe electrical operating
circumstances, and to help avoid potential electromagnetic interference (emi)
and ground noise that can cause unfavorable operating conditions for your
XM system.
DIN Rail Ground
The DIN rail must be grounded. It can be connected to chassis or earth
ground using either the DIN Rail Grounding Block (Figure 2.2) or DIN Rail
mounting bolts (Figure 2.3). If the DIN Rail is coated with a non-conductive
material (anodized, painted, etc.), scrape the material around the mounting
hole.

Figure 2.2 DIN Rail Grounding Block
Figure 2.3 DIN Rail Mounting Bolts
XM System Ground
The XM system must be connected to chassis or earth ground at a single
point. This means that all grounds are connected or tied down at one location
to prevent ground loops between equipment. It is highly recommended that
the single point be at an XM module (24V Common terminal), as shown in the
Figure 2.4, or at the 24V power supply. Use 14 AWG wire.
IMPORTANT
Publication ENMON-UM001A-EN-P - October 2004
The 24V Common and Signal Common terminals are
internally connected. They are isolated from Chassis GND
unless they are connected to Chassis GND as described in
this section.

Installing the XM-120 Eccentricity Module
For multiple XM systems that do not share the same power supply, each XM
system must be connected to chassis or earth ground. Conversely, XM systems
that do not share a common single-point ground require their own power
supply. See Figure 2.6.

Transducer Ground
Make certain the transducers are electrically isolated from chassis ground.
Cable shields must be grounded at one end of the cable, and the other end left
floating or not connected. It is recommended that where possible, the cable
shield be grounded at the XM terminal base and not at the transducer.
DeviceNet Power Supply Ground
The DeviceNet network power supply must also be grounded to earth or
chassis ground at a single point. XM modules do not require an external
DeviceNet power supply. In an XM-only system installation, connect
DeviceNet V- to earth ground at one of the XM modules, as shown in Figure
2.7.

Installing the XM-120 Eccentricity Module
Mounting the Terminal
Base Unit
The XM family includes several different terminal base units to serve all of the
XM modules. The XM-940 terminal base, Entek Cat. No. 1440-TB-A, is the
only terminal base unit used with the Eccentricity module.
Use the following steps to mount the XM-940 terminal base unit on a DIN
rail.
ATTENTION
The XM modules make a chassis ground connection
through the DIN rail. Use zinc plated, yellow chromated
steel DIN rail to assure proper grounding. Using other
DIN rail materials (e.g. aluminum, plastic, etc.), which can
corrode, oxidize or are poor conductors can result in
improper or intermittent platform grounding.
If you are not using the recommended DIN rail, connect
one of the chassis ground terminals on the XM terminal
base to a DIN Rail Grounding Block (C).
1. Position the terminal base on the 35 x 7.5mm DIN rail (A).
Position terminal base at a slight angle and hook over the top of the DIN rail.
2. Slide the terminal base unit over leaving room for the side
connector (B).

3. Rotate the terminal base onto the DIN rail with the top of the rail
hooked under the lip on the rear of the terminal base.
4. Press down on the terminal base unit to lock the terminal base on the
DIN rail. If the terminal base does not lock into place, use a screwdriver
or similar device to open the locking tab, press down on the terminal
base until flush with the DIN rail and release the locking tab to lock the
base in place.
Interconnecting Terminal Base Units
Follow the steps below to install another terminal base unit.
IMPORTANT
Make certain you install the terminal base units in order of
left to right.
1. Position the terminal base on the 35 x 7.5mm DIN rail (A).
2. Make certain the side connector (B) is fully retracted into the base unit.
3. Slide the terminal base unit over tight against the neighboring terminal
base. Make sure the hook on the terminal base slides under the edge of
the terminal base unit.
4. Press down on the terminal base unit to lock the terminal base on the
DIN rail. If the terminal base does not lock into place, use a screwdriver
or similar device to open the locking tab, press down on the terminal
base until flush with the DIN rail and release the locking tab to lock the
base in place.

24V Common and Signal Common are internally connected. These terminals are isolated from Chassis GND
unless they are connected to Chassis GND as described in the Grounding Requirements section (page 7).
Connecting the Power Supply
The power supply to the module is nominally 24V dc. The XM-120 provides
two 24V dc power supply connections. The connections are electrically
isolated from each other so power interruption to one connection does not
affect the other connection. This allows you to have a redundant power supply
for systems used in critical applications.
Publication ENMON-UM001A-EN-P - October 2004

-
The primary 24V dc needs to be wired to terminal 44
(+24V In 1) to provide power to the device and other XM
modules located on the DIN rail. Terminal 42 (+24V In 2)
should be used if a second, or redundant, power supply is
needed. Note that the redundant power supply provides
power only to the XM-120 and not other XM modules on
the DIN rail.
The power connections are different for different XM
modules. Refer to the installation instructions for your
specific XM module for complete wiring information.
Installing the XM-120 Eccentricity Module
19
Connecting the Relays
The XM-120 has both Normally Open (NO) or Normally Closed (NC) relay
contacts. Normally Open relay contacts close when the control output is
energized. Normally Closed relay contacts open when the control output is
energized.
The alarms associated with the relay and whether the relay is normally
de-energized (non-failsafe) or normally energized (failsafe) depends on the
configuration of the module. Refer to Relay Parameters on page 47 for details.
Figure 2.11 through Figure 2.14 show the on-board relay connections for the
module.
IMPORTANT
TIP
IMPORTANT
All XM relays are double pole. This means that each relay
has two contacts in which each contact operates
independently but identically. The following information
and illustrations show wiring solutions for both contacts;
although, in many applications it may be necessary to wire
only one contact.
The Expansion Relay module may be connected to the
module to provide additional relays. Refer the XM-441
Expansion Relay Module User’s Guide for wiring details.
The NC/NO terminal descriptions (page 17) correspond
to a de-energized (unpowered) relay.
When the relay is configured for non-failsafe operation, the
relay is normally de-energized. See Figures 2.11 and 2.13.
When the relay is configured for failsafe operation, the
relay is normally energized, and the behavior of the NC and
NO terminals is inverted. See Figures 2.12 and 2.14.

Connecting the Tachometer Signal
The XM-120 provides a single tachometer input signal. The signal processing
performed on the tachometer signal depends on the configuration of the
module. See page 43 for a description of the tachometer parameters.
IMPORTANT
Publication ENMON-UM001A-EN-P - October 2004
If you are not using the tachometer input, set the Pulses
per Revolution parameter to zero (0). This will disable the
tachometer measurement and prevent the module from
indicating a tachometer fault (TACH indicator flashing
yellow). A tachometer fault occurs when no signal pulses
are received on the tachometer input signal for a relatively
long period.

The XM-120 provides buffered outputs of all transducer input signals. The
buffered output connections may be used to connect the module to portable
data collectors or other online systems.

You may ground the cable shield at either end of the cable.
Do not ground the shield at both ends. Recommended
practice is to ground the cable shield at the terminal base
and not at the transducer. Any convenient Chassis GND
terminal may be used (see Terminal Block Assignments on
page 15).

Connecting the Remote Relay Reset Signal
If you set the module relay to latching and the relay activates, the relay stays
activated even when the condition that caused the alarm has ended. The
remote relay reset signal enables you to reset your module relay remotely after
you have corrected the alarm condition. This includes latched relays in the
Expansion Relay module when it is attached to the XM-120.
TIP
You can discretely reset a relay using the serial or remote
configuration tool.
Wire the Remote Relay Reset Signal to the terminal base unit as shown in
Figure 2.20.

Serial Port Connection
The XM-120 includes a serial port connection that allows you to connect a PC
to it and configure the module’s parameters. There are two methods of
connecting an external device to the module’s serial port.
• Terminal Base Unit - There are three terminals on the terminal base
unit you can use for the serial port connection. They are TxD, RxD, and
RTN (terminals 7, 8, and 9, respectively). If these three terminals are
wired to a DB-9 female connector, then a standard RS-232 serial cable
with 9-pin (DB-9) connectors can be used to connect the module to a
PC (no null modem is required).
The DB-9 connector should be wired to the terminal block as shown.

• USB-Style Connector - The USB-style connector is located on the top
of the module, as shown below.
Figure 2.22 USB-style Connector
USB-style connector
A special cable (Entek Cat. No. 1440-SCDB9FXM2) is required for this
connection. The connector that inserts into the PC is a DB-9 female
connector, and the connector that inserts into the module is a USB
Mini-B male connector.
WARNING
If you connect or disconnect the serial cable with power
applied to the module or the serial device on the other end
of the cable, an electrical arc can occur. This could cause an
explosion in hazardous location installations. Be sure that
power is removed or the area is nonhazardous before
proceeding.
DeviceNet Connection
The XM-120 includes a DeviceNet™ connection that allows the module to
communicate with a programmable controller, DCS, or another XM module.
DeviceNet is an open, global, industry-standard communications network
designed to provide an interface through a single cable from a programmable
controller to a smart device such as the XM-120. As multiple XM modules are
interconnected, DeviceNet also serves as the communication bus and protocol
that efficiently transfers data between the XM modules.
Connect the DeviceNet cable to the terminal base unit as shown.

ATTENTION
ATTENTION
You must ground the DeviceNet shield at only one
location. Connecting the DeviceNet shield to terminal 10
will ground the DeviceNet shield at the XM module. If you
intend to terminate the shield elsewhere, do not connect
the shield to terminal 10.
The DeviceNet power supply must also be grounded at
only one location. XM modules do not require an external
DeviceNet power supply. This means that in an XM-only
system installation, connect DNET V- to earth or chassis
ground at one of the XM modules. In a system in which
other DeviceNet products and a separate DeviceNet power
supply are present, the earth ground connection should be
made at the DeviceNet power supply and not at the XM
module.
The DNet V+ and DNet V- terminals are inputs to the XM
module. Do not attempt to provide DeviceNet power to
other equipment by connecting to these terminals. Failure
to comply may result in damage to the XM terminal base
and/or other equipment.
The devices are shipped from the factory with the network node address
(MAC ID) set to 63. The network node address is software settable. You can
use the XM Serial Configuration Utility or RSNetWorx™ for DeviceNet
(Version 3.0 or later) to set the network node address. Refer to the appropriate
documentation for details.
IMPORTANT
The baud rate for the XM-120 is set by way of “baud
detection” (Autobaud) at power-up.
For more information on DeviceNet installation, refer to the DeviceNet Cable
System Planning and Installation Manual (Publication DN-6.7.2).

Failsafe operation means that when in alarm, the
relay contacts are in their “normal,” de-energized, or

The following are true of a relay in failsafe
operation:
• The relay is energized when power is applied to
the module.
• The relay in a nonalarmed condition has power
applied to the coil.
• In alarm condition, power is removed from the
relay coil, causing the relay to change state.
For non-failsafe operation, the following are true:
• Under nonalarm conditions, the relay closes the
circuit between the common and the N.C.
(normally closed) terminals.
• Under alarm conditions, the relay changes state to
close the circuit between the common and the
N.O. (normally open) terminals.
For failsafe operation, the following are true:
• Under nonalarm (with power applied to the unit)
conditions, the relay closes the circuit between the
common and the N.O. terminals.
• Under alarm or loss-of-power conditions, the relay
changes state to close the circuit between the
common and the N.C. terminals.

Configuration Parameters
IMPORTANT
IMPORTANT
Measured values between Min Range and Max Range are
scaled into the range from 4.0 to 20.0 to produce the
output value. The Min Range value does not have to be
less than the Max Range value. If the Min Range value is
greater than the Max Range value, then the output signal
is effectively inverted from the input signal.
The 4-20mA outputs are either on or off. When they are
on, the 4-20mA outputs overshoot the 4 and 20mA limits
by 10% when the measurement exceeds the minimum and
maximum range. This means the minimum current
produced is 3.6mA and the maximum current produced is
22mA.
When the 4-20mA outputs are off, they produce a current
approximately 2.9mA. The 4-20mA outputs are off under
the following conditions:
• The 4-20mA outputs are set to "Disable" (see Enable on
the previous page).
• The module is in Program mode.
• A transducer fault or tachometer fault occurs that affects
the corresponding measurement.
The I/O data parameters are used to configure the content and size of the
DeviceNet I/O Poll response message.

IMPORTANT
The XM-120 must be free of Poll connections when
configuring the Poll Output (Poll Response Assembly)

DeviceNet Information
Electronic Data Sheets
Electronic Data Sheet (EDS) files are simple text files used by network
configuration tools such as RSNetWorx (Version 3.0 or later) to help you
identify products and easily commission them on a network. The EDS files
describe a product’s device type, product revision, and configurable parameters
on a DeviceNet network.
The EDS files for the XM modules are installed on your computer with the
XM configuration software. The latest EDS files can also be obtained at
http://www.ab.com/networks/eds/ or by contacting your local Rockwell
Automation representative.
Refer to your DeviceNet documentation for instructions on registering the
EDS files.
Changing Operation Modes
XM modules operate in two modes.
Mode
Description
Run
The XM measurement modules collect measurement data and
monitor each measurement device.
The XM-440 establishes I/O connections with the XM
measurement modules in its scan list and monitors their alarms,
and controls its own relay outputs accordingly.
Program
The XM module is idle.
The XM measurement modules stop the signal
processing/measurement process, and the status of the alarms
is set to the disarm state to prevent a false alert or danger
status.
The XM-440 closes the I/O connections with the XM
measurement modules in its scan list and stops monitoring their
alarms, relays are deactivated unless they are latched.
Configuration parameters can be read, updated and downloaded
to the XM module.
To change the operation mode of the module, use the Device Mode parameter
in the EDS file. Note that the Stop and Start services described on page 65 can
also be used to change the operation mode.
IMPORTANT
63
The XM Serial Configuration Utility software automatically
puts XM modules in Program mode and Run mode
without user interaction.

DeviceNet Information
Transition to Program Mode
Parameter values can only be downloaded to an XM module while the module
is in Program mode. Any attempt to download a parameter value while the
module is in Run mode will result in a Device State Conflict error.
To transition an XM module from Run mode to Program mode on a
DeviceNet network, set the Device Mode parameter to “Program mode” and
click Apply. Note that you cannot change any other parameter until you have
downloaded the Program mode parameter.
TIP
The Module Status indicator flashes green when the
module is in Program mode.
Refer to your DeviceNet documentation for specific instructions on editing
EDS device parameters.
TIP
You can also use the Stop service described on page 65 to
transition XM modules to Program mode.
Transition to Run Mode
In order to collect data and monitor measurement devices, XM modules must
be in Run mode. To transition an XM module from Program mode to Run
mode on a DeviceNet network, set the Device Mode parameter to “Run
mode” and click Apply.
TIP
The Module Status indicator is solid green when the
module is in Run mode.
Refer to your DeviceNet documentation for specific instructions on editing

Automatic Device Replacement (ADR) is a feature of an Allen-Bradley
DeviceNet scanner. It provides a means for replacing a failed device with a
new unit, and having the device configuration data set automatically. Upon
replacing a failed device with a new unit, the ADR scanner automatically
downloads the configuration data and sets the node address.
ADR can be used with XM modules but keep the following in mind when
setting up the XM modules.
Publication ENMON-UM001A-EN-P - October 2004
DeviceNet Information
71
• The ADR scanner can not download the configuration data to an XM
module if the module has a saved configuration in its non-volatile
memory. This happens because the saved configuration is restored and
the module enters Run mode when the power is cycled. (Configuration
parameters cannot be downloaded while an XM module is in Run
mode.) XM modules must be in Program mode for the ADR
configuration to be downloaded and this occurs only when there is no
saved configuration.
TIP
To delete a saved configuration from non-volatile
memory, use the Delete service in RSNetWorx for
DeviceNet or perform the following steps in the XM
Serial Configuration Utility.
1. Save the current configuration to a file. From the
File menu, click Save As and enter a file name for
the configuration.
2. Reset the module to factory defaults. Click the
Module tab and click the Reset button.
3. Reload the saved configuration. From the File
menu, click Open and select the configuration file.
4. Make certain to disable auto save. From the Device
menu, clear the Auto Save Configuration check
mark.
• An XM module will enter Run mode automatically after the ADR
scanner restores the module’s configuration only if the module is in Run
mode at the time the configuration is saved to the scanner. If the
module is in Program mode when the configuration is saved, then the
module will remain in Program mode after the configuration is
downloaded by the ADR scanner.
• The ADR scanner saves and restores only the configuration parameters
contained in the module’s EDS file. Some XM parameters are not
included in the EDS file because they are not supported by either the
EDS specification or the tools that read the EDS files, for example
RSNetWorx for DeviceNet. Examples of XM configuration parameters
that are not included in the EDS file include the Name parameters
(Channel, Alarm, and Relay Name) and the Trend parameters. These
configuration parameters will not be restored with ADR.
• The ADR and trigger group functions cannot be used together. A
module can have only one primary master so a module cannot be both
configured for ADR and included in a trigger group. The ADR scanner
must be the primary master for the modules configured for ADR. The
XM-440 Master Relay module must be the primary master for modules
included in a trigger group.

The Baud Rate setting can not be set while Autobaud Disable is equal to 0. Applying the Baud Rate does not
occur until the Reset service to the Identity Object.
The MAC ID, Baud Rate, and Autobaud Disable settings are stored in

The Baud Rate attribute supports the following settings:
• 0 = 125 kbps
• 1 = 250 kbps
• 2 = 500 kbps
The Baud Rate setting is used only when automatic baud rate detection is
disabled (Autobaud Disable = 1). When Autobaud Disable is set to zero
(0), the module ignores its Baud Rate setting and performs automatic baud

The Parameter Object provides the interface to the Eccentricity configuration
data. There are 18 Parameter Object instances implemented in the Eccentricity
module.
Parameter Object
(Class ID 0FH)
Instances 1-4 and 7-16 are implemented to provide an alternate method of
setting the configuration parameters with ENGUNIT or EPATH data type.
And Parameter Object instances 17 and 18 provide an alternate method for
setting the Produced Connection Size and Produced Connection Path
attributes for the Poll Connection because these attributes can be difficult to
get/set directly through the Connection Object.
Parameter Object instances 5 and 6 are for setting the update rate of the
eccentricity measurements. The eccentricity update rate is used in place of the
tachometer when no tachometer is available.

Get_Waveform_Chunk
This service returns a portion of the respective data structure. It is likely that
the waveform data structure will be too large to transfer over the network in
one message. This service allows the data structures to be transferred over the
network in smaller portions so that the explicit message buffer does not need
to be so large.
The Waveform Data structure contains an array of values that, taken together,
are the output of the sampling performed by the Spectrum/Waveform
Measurement Object on the input signal. The Waveform Data array values are
normalized and must be converted to floating point to obtain the true values.

The total size of the Waveform Data structure in DWORD is: 3 + (Number

The Waveform Data is an array of INT (16-bit signed integers ranging from
-32768 to 32767). The number of INTs in the Waveform Data array is equal to
the Number of Waveform Points. To convert the normalized Waveform
Data into floating point values, use the following equations:
Normalized Data n
Float Data n = Amplitude Reference ----------------------------------------------32768
Where Float Datan is the value for the nth waveform point, and 0 ≤ n ≤
Number of Waveform Points.

Semantics of Values
The offset of the first 32-bit value
within the data structure to be

0 <= offset < size of the data structure in
DWORDs.
For example:
offset = 0 refers to bytes 0-3 (the number of
lines or points value)
offset = 1 refers to bytes 4-7 (the FMAX or
period values)
offset = 2 refers to bytes 8-11 (the amplitude
reference value)
offset = 3 refers to bytes 12-15 (the first pair of
normalized values)
offset = 4 refers to bytes 16-19 (the second pair
of normalized values)
....
The number of 32-bit values from
the data structure to be returned.
This should be small enough to fit in the
explicit message buffer. This will likely be less
than the total size of the data structure so that
several calls to the service will be required to
get the entire data structure.

Connecting the Transducer
The Eccentricity module accepts input from any Entek non-contact eddy
current probe. Figures D.2 and D.3 show the wiring of a non-contact eddy
probe to an earlier revision of the XM-120 module (before revision D01).
ATTENTION
IMPORTANT
You may ground the cable shield at either end of the cable.
Do not ground the shield at both ends. Recommended
practice is to ground the cable shield at the terminal base
and not at the transducer. Any convenient Chassis GND
terminal may be used (see Terminal Block Assignments on
page 104).
The internal transducer power supply is providing power to
the non-contact sensor.

alarm
An alarm alerts you to a change in a measurement. For example, an alarm can
notify you when the measured vibration level for a machine exceeds a
pre-defined value.
Automatic Device Replacement (ADR)
A means for replacing a malfunctioning device with a new unit, and having the
device configuration data set automatically. The ADR scanner uploads and
stores a device’s configuration. Upon replacing a malfunctioning device with a
new unit (MAC ID 63), the ADR scanner automatically downloads the
configuration data and sets the MAC ID (node address).
band
A frequency range, such as the frequency range between 1,800 and 3,200Hz.
baud rate
The baud rate is the speed at which data is transferred on the DeviceNet
network. The available data rates depend on the type of cable and total cable
length used on the network:
Maximum Cable Length
Cable
125K
250K
500K
Thick Trunk Line
500m (1,640ft.)
250m (820ft.)
100m (328ft.)

6m (20ft.)
6m (20ft.)
Cumulative Drop Length
156m (512ft.)
78m (256ft.)
39m (128ft.)
The XM measurement modules’ baud rate is automatically set by the bus
master. You must set the XM-440 Relay module’s baud rate. You set the
XM-440 Master Relay to 125kb, 250kb, 500kb, or Autobaud if another device
on the network has set the baud rate.
bus off
A bus off condition occurs when an abnormal rate of errors is detected on the
Control Area Network (CAN) bus in a device. The bus-off device cannot
receive or transmit messages on the network. This condition is often caused by
corruption of the network data signals due to noise or baud rate mismatch.
Change of State (COS)
DeviceNet communications method in which the XM module sends data
based on detection of any changed value within the input data (alarm or relay
status).

current configuration
The current configuration is the most recently loaded set of configuration

configuration is loaded with either the saved configuration (in EEPROM) or
the factory defaults (if there is no saved configuration). In addition, the current
configuration contains any configuration changes that have been downloaded
to the module since power was applied.
DeviceNet network
A DeviceNet network uses a producer/consumer Controller Area Network
(CAN) to connect devices (for example, XM modules). A DeviceNet network
can support a maximum of 64 devices. Each device is assigned a unique node
address (MAC ID) and transmits data on the network at the same baud rate.
A cable is used to connect devices on the network. It contains both the signal
and power wires. General information about DeviceNet and the DeviceNet
specification are maintained by the Open DeviceNet Vendor’s Association
(ODVA). ODVA is online at http://www.odva.org.
disarm state
See Program mode.
eccentricity
Eccentricity is the measurement of shaft bow at slow-roll speed, which can be
caused by any or a combination of:
• Fixed mechanical bow
• Temporary thermal bow
• Gravity bow
EEPROM
See NVS (Non-Volatile Storage).
Electronic Data Sheet (EDS) Files
EDS files are simple text files that are used by network configuration tools
such as RSNetWorx for DeviceNet to describe products so that you can easily
commission them on a network. EDS files describe a product device type,
revision, and configurable parameters.

Help window
A window that contains help topics that describe the operation of a program.
These topics may include:
•
•
•
•
An explanation of a command.
A description of the controls in a dialog box or property page.
Instructions for a task.
Definition of a term.
MAC ID
See node address.
master device
A device which controls one or more slave devices. The XM-440 Master Relay
module is a master device.
Node Address
A DeviceNet network can have as many as 64 devices connected to it. Each
device on the network must have a unique node address between 0 and 63.
Node address 63 is the default used by uncommissioned devices. Node
address is sometimes called “MAC ID.”
NVS (Non-Volatile Storage)
NVS is the permanent memory of an XM module. Modules store parameters
and other information in NVS so that they are not lost when the module loses
power (unless Auto Save is disabled). NVS is sometimes called “EEPROM.”
online help
Online help allows you to get help for your program on the computer screen
by pressing F1. The help that appears in the Help window is context sensitive,
which means that the help is related to what you are currently doing in the
program.
peak-to-peak eccentricity
Measurement that measures the difference between the positive and the
negative extremes of the rotor bow.
Polled
DeviceNet communications method in which module sends data in response
to a poll request from a master device.

Program mode
The XM module is idle. Typically this occurs when the module configuration
settings are being updated with the XM Configuration program. In Program
mode, the signal processing/measurement process is stopped. The status of
the alarms is set to the disarm state to prevent a false alert or danger status.
Run mode
In Run mode, the module collects measurement data and monitors each
measurement device.
slave device
A device that receives and responds to messages from a Master device but
does not initiate communication. Slave devices include the XM measurement
modules, such as the XM-120 Eccentricity module and the XM-320 Position
module.
transducer
A transducer is a device for making measurements. These include
accelerometers, velocity pickups, displacement probes, and temperature
sensors.
virtual relay
A virtual relay is a non-physical relay. It has the same capabilities (monitor
alarms, activation delay, change status) as a physical relay only without any
physical or electrical output. The virtual relay provides additional relay status
inputs to a controller or PLC.
XM configuration
XM configuration is a collection of user-defined parameters for XM modules.
XM Serial Configuration Utility software
XM Serial Configuration Utility software is a tool for monitoring and
configuring XM modules. It can be run on computers running Windows 2000
service pack 2, Windows NT 4.0 service pack 6, or Windows XP operating
systems.
