Using this Manual2
Introducing the XM-123
Module
The XM-123 Aeroderivative module is a member of the Allen-Bradley™ 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.
The XM-123 is a 2-channel monitor designed specifically for monitoring
aeroderivative gas turbine engines, such as the General Electric LM2500
engine. The module can be configured, per channel, to perform either tracking
filter or bandpass filter while it continuously measures each channel’s
broad-band overall level.
The module can power and accept input from standard eddy current probe
systems and Integrated Electronics Piezo Electric (IEPE) accelerometers. The
XM-123 can also accept signals from most standard voltage output
measurement devices such as a velocity or pressure transducer. In addition to
vibration inputs, the XM-123 accepts one tachometer input to provide speed
measurements and order tracking functions.
The XM-123 also includes a single on-board relay (expandable to five), two
4-20mA outputs, and a buffered output for each input. The module can collect
data under steady-state and startup/coast-down conditions, and monitor up to
12 alarms making the module a complete monitoring system.
The XM-123 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 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.

XM Installation
Requirements
This section describes wire, power and grounding requirements for an XM
system.
Wiring Requirements
Use solid or stranded wire. All wiring should meet the following specifications:
• 14 to 22 AWG copper conductors without pretreatment; 8 AWG
required for grounding the DIN rail for electromagnetic interference
(emi) purposes
• Wire ferrules can be used with stranded conductors; copper ferrules
recommended
See the XM Documentation and Configuration Utility CD
for Hazardous Locations installation drawings. The XM
Documentation and Configuration Utility CD is packaged
with the XM modules.
Power Requirements
Before installing your module, calculate the power requirements of all modules
interconnected via their side connectors. The total current draw through the
side connector cannot exceed 3 A. Refer to the specifications for the specific
modules for power requirements.
A separate power connection is necessary if the total
current draw of the interconnecting modules is greater than
3 A.

architecting power supplies for XM systems.
Grounding Requirements
Use these grounding requirements to ensure safe electrical operating
circumstances, and to help avoid potential emi and ground noise that can cause
unfavorable operating conditions for your XM system.
DIN Rail Grounding
The XM modules make a chassis ground connection through the DIN rail.
The DIN rail must be connected to a ground bus or grounding electrode
conductor using 8 AWG or 1 inch copper braid. See Figure 2.2.
Use zinc-plated, yellow-chromated steel DIN rail (Allen-Bradley part no.
199-DR1 or 199-DR4) or equivalent 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.

IMPORTANT
IMPORTANT
24 V Common Grounding
24 V power to the XM modules must be grounded. When two or more power
supplies power the XM system, ground the 24 V Commons at a single point,
such as the ground bus bar.
If it is not possible or practical to ground the -24Vdc
supply, then it is possible for the system to be installed and
operate ungrounded. However, if installed ungrounded
then the system must not be connected to a ground
through any other circuit unless that circuit is isolated
externally. Connecting a floating system to a non-isolated
ground could result in damage to the XM module(s)
and/or any connected device. Also, operating the system
without a ground may result in the system not performing
to the published specifications regards measurement
accuracy and communications speed, distance or reliability.
The 24 V Common and Signal Common terminals are
internally connected. They are isolated from the Chassis
terminals unless they are connected to ground as described
in this section. Refer to Terminal Block Assignments on
page 18 for more information.
Transducer Grounding
Make certain the transducers are electrically isolated from earth 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 (Chassis terminal) and not at the
transducer.
DeviceNet Grounding
The DeviceNet network is functionally isolated and must be referenced to
earth ground at a single point. XM modules do not require an external
DeviceNet power supply. Connect DeviceNet V- to earth ground at one of the
XM modules, as shown in Figure 2.6.

ATTENTION
Use of a separate DeviceNet power supply is not
permitted. See Application Technique "XM Power Supply
Solutions", publication ICM-AP005A-EN-E, for guidance
in using XM with other DeviceNet products.

Mounting the Terminal
Base Unit
For more information on the DeviceNet installation, refer to the ODVA
Planning and Installation Manual - DeviceNet Cable System, which is available
on the ODVA web site (http://www.odva.org).
Switch Input Grounding
The Switch Input circuits are functionally isolated from other circuits. It is
recommended that the Switch RTN signal be grounded at a single point.
Connect the Switch RTN signal to the XM terminal base (Chassis terminal) or
directly to the DIN rail, or ground the signal at the switch or other equipment
that is wired to the switch.
The XM family includes several different terminal base units to serve all of the
XM modules. The XM-940 terminal base, Cat. No. 1440-TB-A, is the only
terminal base unit used with the XM-123 module.
Publication GMSI10-UM003D-EN-P - May 2010
14
ATTENTION
Position terminal base at a slight angle and hook over the top of the DIN rail.
The terminal base can be DIN rail or wall/panel mounted. Refer to the
specific method of mounting below.
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.
You can also mount the terminal base to a grounded
mounting plate. Refer to Panel/Wall Mount Grounding on
page 10.

24Vdc needs to be wired to terminal 44 (+24 V In) to
provide power to the device and other XM modules linked
to the wired terminal base via the side connector.
The power connections are different for different XM
modules. Refer to the installation instructions for your
specific XM module for complete wiring information.
Connecting the Relays
The XM-123 has both Normally Open (NO) and 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 64 for details.
Publication GMSI10-UM003D-EN-P - May 2010
22
IMPORTANT
TIP
IMPORTANT
Table 2.1 shows the on-board relay connections for the XM-123.
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 Guide for wiring details.
The NC/NO terminal descriptions (page 20) correspond
to a de-energized (unpowered) relay.
When the relay is configured for non-failsafe operation, the
relay is normally de-energized.
When the relay is configured for failsafe operation, the
relay is normally energized, and the behavior of the NC and
NO terminals is inverted.
Figures 2.9 and 2.10 illustrate the behavior of the NC and NO terminals when

The XM-123 provides a single tachometer input signal. The signal processing
performed on the tachometer signal depends on the configuration of the
module. See page 57 for a description of the tachometer parameters.
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 voltage operating range of the buffered outputs must
be configured to coincide with the corresponding
transducer bias range. This operating range is configured by
placing a jumper from terminal 5 (channel 1) and terminal
22 (channel) to either terminal 6 (Positive Buffer Bias) or
terminal 21 (Buffer -), depending on the transducer. See
Table 2.2. The buffered output operating range is
configured independently per channel.

ATTENTION
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-123.
If you set a module relay to latching, make sure that any
linked relays, such as relays in an XM-440 Master Relay
Module, are not configured as latching. When both relays
are set to latching, the relay in each module will have to be
independently reset when necessary.
You can discretely reset an individual relay using the serial
or remote configuration tool.
Wire the Remote Relay Reset Signal to the terminal base unit as shown on
Figure 2.28.
Figure 2.28 Remote Relay Reset Signal Connection
The Switch Input circuits are functionally isolated from
other circuits. It is recommended that the Switch RTN
signal be grounded at a signal point. Connect the Switch
RTN signal to the XM terminal base (Chassis terminal) or
directly to the DIN rail, or ground the signal at the switch
or other equipment that is wired to the switch.
Publication GMSI10-UM003D-EN-P - May 2010
39
ATTENTION
A single switch contact can also be shared by multiple XM modules wired in
parallel as shown in Figure 2.29.
The relay reset connections may be different for different
XM modules. Figure 2.29 applies only to the XM-123
module. Refer to the installation instructions for the
module for its terminal assignments.
You can configure the module to multiply the alarm setpoints, or inhibit the
alarms during the start-up period. This can be used to avoid alarm conditions
that may occur during startup, for example, when the monitored machine
passes through a critical speed.
Wire the Setpoint Multiplication switch to the terminal base unit as shown in
Figure 2.30.

or other equipment that is wired to the switch.
Connecting the 4-20 mA Outputs
The module includes an isolated 4-20 mA per channel output into a maximum
load of 300 ohms. The measurements that the 4-20 mA output tracks and the
signal levels that correspond to the 4 mA and 20 mA are configurable. Refer
to 4-20 mA Output Parameters on page 68 for details.
Wire the 4-20 mA outputs to the terminal base unit as shown in Figure 2.31.

Figure 2.31 4-20 mA Output Connections
ATTENTION
-
The 4-20 mA outputs are functionally isolated from other
circuits. It is recommended that the outputs be grounded at
a single point. Connect the 4-20 mA (-) to the XM terminal
base (Chassis terminal) or directly to the DIN rail, or
ground the signal at the other equipment in the 4-20 mA
loop.
41
PC Serial Port Connection
The XM-123 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.
• Ter min a l Bas e Uni t - 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.
• Mini-Connector - The mini-connector is located on the top of the
module, as shown below.
Figure 2.32 Mini-Connector
A special cable (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.
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.
If 24 V Common is not referenced to earth ground, we
recommend you use an RS-232 isolator, such as Phoenix
PSM-ME-RS232/RS232-P (Cat. No. 1440-ISO-232-24), to
protect both the XM module and the computer.
DeviceNet Connection
The XM-123 includes a DeviceNet™ connection that allows the module to
communicate with a Programmable Logic Controller (PLC), Distributed
Control System (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-123. As multiple XM modules are
interconnected, DeviceNet also serves as the communication bus and protocol
that efficiently transfers data between the XM modules.

or designed to power DeviceNet loads. Doing so could
damage the module or terminal base.
To preclude this possibility, even unintentionally, it is
recommended that DeviceNet V+ be left unconnected.
43
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 network must also be referenced to earth at
only one location. Connect DNet V- to earth or chassis at
one of the XM modules.
The DNet V+ and DNet V- terminals are inputs to the XM
module. Do not attempt to pass DeviceNet power through
the XM terminal base to other non-XM equipment by
connecting to these terminals. Failure to comply may result
in damage to the XM terminal base and/or other
equipment.
Terminate the DeviceNet network and adhere to the
requirements and instructions in the ODVA Planning and
Installation Manual - DeviceNet Cable System, which is
available on the ODVA web site (http://www.odva.org).
The device is shipped from the factory with the network node address (MAC

Mounting the Module
The XM-123 mounts on the XM-940 terminal base unit, Cat. No. 1440-TB-A.
We recommend that you mount the module after you have connected the
wiring on the terminal base unit.
The XM-123 module is compatible only with the XM-940
terminal base unit. The keyswitch on the terminal base unit
should be at position 1 for the module.
Do not attempt to install XM-123 modules on other
terminal base units.
Do not change the position of the keyswitch after
wiring the terminal base.
This module is designed so you can remove and insert it
under power. However, when you remove or insert the
module with power applied, I/O attached to the module
can change states due to its input/output signal changing
conditions. Take special care when using this feature.
When you insert or remove the module while power is on,
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.

The Channel LED will flash red when a transducer fault
condition exists on the channel even if you are not using
the channel. You can keep the Channel LED from flashing
red on unused channels by configuring the channel
transducer parameters as follows:
• Set the unused channel’s Fault High and Fault Low to
greater than zero and less than zero, respectively. For
example, set Fault High to +18 volts and set Fault Low
to -18 volts.
• Disable the unused channel’s transducer power by

• RMS - The Overall Value is the root mean squared
(RMS) signal level of the input signal.
• Calculated Peak - The Overall Value is the
measured RMS value multiplied by the square root
of two (1.4142).
• Calculated Peak-to-Peak - The Overall Value is
the measured RMS value multiplied by two times
the square root of two (2.8284).
• True Peak - The Overall Value is the output of a
peak detector applied to the input signal.
• True Peak-to-Peak - The Overall Value is the
output of a peak-to-peak detector applied to the
input signal.
Important: When changing the signal

parameter sets the 3-DB bandwidth for the digital
filtering used to calculate the Overall Value. The
3-dB bandwidth is roughly equal to 1 / (2
π x Overall
Time Constant). The greater the Overall Time
Constant, the slower the response of the measured
Overall Value to change in the input signal.
Recommended Value:
The recommended values are
appropriate for a typical 50/60Hz
machine, and may need to be adjusted
depending on the application.
For example, an Overall Time Constant of 0.1
seconds may be appropriate for monitoring the
Overall Value of an input signal with a fundamental
frequency of 10 Hz and above. Although, the
response to a step change in input will take
approximately 2.2 times the Overall Time Constant to
settle. Therefore, for an Overall Time Constant of 0.1
seconds, the settling time will be approximately 0.22
seconds.
For True Peak measurements, the Overall Time
Constant sets the decay rate of the peak detection
meter. The greater the Overall Time Constant, the
slower the Peak is decayed.
Overall Damping FactorThis parameter is used in conjunction with the
Overall Time Constant to vary the characteristics
of the response of the digital filter used in
calculating the Overall Value.
An Overall Value for a measurement with a damping
factor near 1.0 (critical damping) will slowly rise or
fall for the full settling time specified by the Overall Time Constant before reaching the final value. An
Overall Value for a measurement with a damping
factor near 0.707 will rise or fall quickly and may
"overshoot" (measure a value greater or less than the
final value) before reaching the final value for a
given input signal.
Overall FilterThe filter to be applied to the overall measurement
to produce the Overall Value. See Data Parameters
on page 76.
Low Pass FilterSets the frequency above which the input signal will
be significantly attenuated.
• For True Peak or True
Peak-to-Peak measurements, set
the Overall Time Constant to 1.5.
• For RMS, Calculated Peak, or
Calculated Peak-to-Peak
measurements, set the Overall Time
Constant to one of the
following:
Enter a value from 0.707 to 1.0.
Options: None

Relay Parameters
The Relay parameters control the operation of the on-board relay, as well as
the relays on the Expansion Relay (XM-441) module. Use these parameters to
configure which alarm(s) the relay is associated with, as well as the behavior of
the relay.
A relay can be defined, regardless of whether or not it is
physically present. A non-physical relay is a virtual relay.
When a relay (physical or virtual) activates, the module
sends a Change of State (COS) message to its master,
which acts on the condition as necessary. An XM-440
Master Relay Module can activate its own relays in response
to a relay (physical or virtual) activation at any of its slaves.

Parameter Name DescriptionOptions/Comments
Determines whether the relay is failsafe or
non-failsafe.
Failsafe operation means that when in alarm, the
relay contacts are in their "normal," de-energized, or
"shelf-state" positions. In other words, normally
closed relays are closed in alarm, and normally open
relays are open in alarm. With failsafe operation, a
power failure equals an alarm.
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.
67
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.

4-20 mA Output Parameters
The 4-20 mA output parameters define the characteristics of the two 4-20 mA
output signals. The parameters are the same for each output.
4-20 mA Parameters
Parameter Name DescriptionOptions/Comments
EnableEnables/disables the 4-20 mA output.
MeasurementSets the type of measurement and the channel that
the 4-20 mA output signal will track.
Options: Ch1 / Ch2 Overall
Important: The tracking and band
measurement selections depend on
which filter measurement (Bandpass
Filter or Tracking Filter) is selected.
See Aeroderivative Measurement

For example in the XM Serial

Bandpass Filter for channel 1 and
Tracking Filter for channel 2, then
the measurement selection would
include "Ch1 Band" and "Ch2 Tracking
Magnitude" but not "Ch2 Band" or
"Ch1 Tracking Magnitude."
Min Range The measured value associated with the 4 mA.Same measurement unit as Output
Max RangeThe measured value associated with the 20 mA.
Data Unit selection for the specified
channel.
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.
Publication GMSI10-UM003D-EN-P - May 2010
69
IMPORTANT
IMPORTANT
The 4-20 mA outputs are either on or off. When they are
on, the 4-20 mA outputs overshoot the 4 and 20 mA limits
by 10% when the measurement exceeds the minimum and
maximum range. This means the minimum current
produced is 3.6 mA and the maximum current produced is
22 mA.
When the 4-20 mA outputs are off, they produce a current
approximately 2.9 mA. The 4-20 mA outputs are off under
the following conditions:
• The 4-20 mA 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.
Triggered Trend Parameters
The XM-123 module can collect a triggered trend. A triggered trend is a
time-based trend that is collected when a relay is activated, or the module
receives a trigger event.
Once the triggered trend is configured, the XM-123 continuously monitors the
trended measurements. When a trigger occurs, the XM-123 collects additional
data as specified by the Post Trigger parameter.
The XM-123 can only store one triggered trend. Unless the triggered trend is
latched, the trend data is overwritten with new data when the next trigger
occurs.
The triggered trend parameters define the trend data that is collected by the
module. Use these parameters to select the measurements included in the
trend records, the interval between trend records, and which relay triggers
(activates) the collection of the trend data.
The Triggered Trend parameters are not included in the
EDS file and cannot be edited using generic configuration
tools such as RSNetWorx for DeviceNet.
Enables/disables the triggered trend measurements.
Select to configure the triggered trend
measurements.
Select Measurements Sets the measurements to be collected and stored in
the module.
Number of RecordsThe maximum number of measurement sets that can
be collected in the trend buffer. The measurement
sets make up the trend data.
Latch EnableDetermines whether the trigger trend is latched or
unlatched.
Check to enable.
Clear to disable.
More than one measurement can be
selected.
Important: Make certain to check
your filter selection (Tracking Filter
or Bandpass Filter).
The XM-123 can produce either the
bandpass or tracking measurements
depending on which filter is selected.
If you select a band or tracking
measurement that is not being
produced by the module, a trend of
zeroes will be stored for that
measurement.
For example, if you select the "Ch1
Band" measurement but the
Bandpass Filter for Channel 1 is not
selected, the module will store zeroes
in the trend for the CH1 Band
measurement.
The Number of Records is
automatically calculated based upon
the number of Trended Measurements selected.
Check means latched
Clear means unlatched
Latched means that subsequent triggers are ignored
after the initial trigger. This prevents the trend data
from being overwritten with new data until the
trigger is manually reset (click Reset Trigger button).
Unlatched means that the trend data is overwritten
with new data every time a trigger occurs.
Relay NumberSets the relay that triggers the trend to be collected. None means that the trend can only be
triggered manually or by a trigger
event (for example, XM-440).
Relay Numbers 1 through 5 are either
relays on the Expansion Relay module
when it’s connected to the module or
virtual relays.
Note: The relay must be enabled.
Refer to Relay Parameters on page 64.

20%, then 80% of the records in the trend are before
the trigger occurs, and 20% of the records in the
trend are after the trigger occurs.
This allows you to evaluate what happened after the
trigger occurred.

SU/CD Trend Parameters
The XM-123 can collect startup or coast-down trend data when the machine
speed passes into a defined speed range. A tachometer input is required to
collect the startup/coast-down trend.
The XM module collects a startup trend when the machine speed rises
through the Minimum Speed + 8 RPM, and stops when the machine speed
crosses either the Minimum Speed or the Maximum Speed. The module
collects data only when machine speed is increasing. It does not collect data if
the machine speed is constant or decreasing.
Publication GMSI10-UM003D-EN-P - May 2010
72
IMPORTANT
The XM module collects a coast-down trend when the machine speed falls
through the Maximum Speed - 8 RPM, and stops when the machine speed
crosses either the Minimum Speed or the Maximum Speed. The module
collects data when the machine speed is decreasing or increasing during a
coast-down trend (for example, a coast-down restart).
The XM-123 can only store one startup/coast-down trend. Unless the
startup/coast-down trend is latched, the trend data is overwritten with new
data when the next trigger occurs.
The SU/CD trend parameters define the trend data that is collected by the
module during the startup or coast-down of a machine. Use these parameters
to configure the measurements included in the startup and coast-down trend
records, the interval between trend records, and the minimum and maximum
speed limits at which record collection starts and stops.
The SU/CD Trend parameters are not included in the EDS
file and cannot be edited using generic configuration tools
such as RSNetWorx for DeviceNet.

Electronic Data Sheets
Changing Operation Modes
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.
XM modules operate in two modes.
ModeDescription
RunThe 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.
ProgramThe 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 91 can
also be used to change the operation mode.
The XM Serial Configuration Utility software automatically
puts XM modules in Program mode and Run mode
without user interaction.

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.
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.
You can also use the Stop service described on page 91 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.
The Module Status indicator is solid green when the
module is in Run mode.
Refer to your DeviceNet documentation for specific instructions on editing
EDS device parameters.
You can also use the Start service described on page 91 to
transition XM modules to Run mode.
