The XM-361 Universal Temperature module and the XM-362 Isolated
Thermocouple Temperature module are members 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-361 and XM-362 modules are intelligent 6-channel temperature
monitors. The XM-361 module can be configured to measure either
Resistance Temperature Detector (RTD) or Thermocouple (TC), or a mixture
of RTD or TC inputs. The XM-362 module provides 250V dc of
channel-to-channel isolation and is specifically designed to measure
temperature with Thermocouple inputs.
For applications where it is not possible to integrate XM data directly via
DeviceNet, the XM-361 and XM-362 provide separate 4-20mA outputs for
each channel. And for applications requiring relays, the modules support
connecting up to two XM-441 Expansion Relay modules, providing a total of
eight relays. The XM-361/362 can also collect trend data on an event such as a
relay actuation.
The modules can operate stand-alone, or they can be deployed on a standard
or dedicated DeviceNet network where they can provide real-time data and
status information to other XM modules, PLCs, distributed control systems
(DCS), and Condition Monitoring Systems.
The XM-361 and XM-362 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-944 Temperature Module Terminal Base - A DIN rail mounted
base unit that provides terminations for all field wiring required by XM
Temperature modules, including the XM-361 and XM-362.
• XM-361/362 Temperature Module - The module mounts on the
XM-944 terminal base via a keyswitch and a 96-pin connector. The
module contains the measurement electronics, processors, and serial
interface port for local configuration.
IMPORTANT
Up to two XM-441 Expansion Relay modules may be
connected to the XM-361 or XM-362 module via the
XM-944 terminal base.
When connected to the module, the Expansion Relay
modules simply "expand" the capability of the XM-361 or
XM-362 by providing a total of up to eight relays. The
Temperature module controls the operation of the
Expansion Relay modules.

XM Installation
Requirements
This section describes requirements and considerations for an XM system.
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
• Recommended strip length 8 millimeters (0.31 inches)
• Minimum insulation rating of 300 V
• Soldering the conductor is forbidden
• Wire ferrules can be used with stranded conductors; copper ferrules
recommended
ATTENTION
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.
RTD Wiring Considerations
When using RTDs as inputs, give special consideration when selecting the
input cable. Select a cable that has consistent impedance throughout its entire
length.
IMPORTANT
Publication GMSI10-UM008D-EN-P - August 2010
The XM-361 requires three wires to compensate for lead
resistance error. We recommend that you do not use 2-wire
RTDs if long cable runs are required, as it reduces the
accuracy of the system. However, if a 2-wire configuration
is required, reduce the effect of the lead wire resistance by
using a lower-gauge wire for the cable (for example, use
16 AWG instead of 24 AWG).
7
When using a 3-wire configuration, the XM-361 compensates for resistance
error due to lead wire length. For example, in a 3-wire configuration, the
XM-361 reads the resistance due to the length of the wires and assumes that
the resistance of the other wire is equal. If the resistance of the individual lead
wires is much different, an error may exist. The closer the resistance values are
to each other, the greater the amount of error is eliminated.
IMPORTANT
To ensure temperature or resistance value accuracy, the
resistance difference of the cable lead wires must be equal
to or less than 0.01 ohm.
To ensure that the lead values match as closely as possible:
• Keep lead resistance as small as possible and less than 50 ohms.
• Use quality cable that has a small tolerance impedance rating.
• Use a heavy-gauge lead wire which has less resistance per foot.
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.
ATTENTION
A separate power connection is necessary if the total
current draw of the interconnecting modules is greater than
3 A.
Figure 2.1 is an illustration of wiring modules using separate power
connections.

IMPORTANT
See Application Technique "XM Power Supply Solutions",
publication ICM-AP005A-EN-E, for guidance in
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.

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.
IMPORTANT
IMPORTANT
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.
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.
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).
Mounting the Terminal
Base Unit
The XM family includes several different terminal base units to serve all of the
measurement modules. The XM-944 terminal base, Cat. No. 1440-TB-E, is the
only terminal base unit used with the Temperature modules.
The terminal base can be DIN rail or wall/panel mounted. Refer to the
specific method of mounting below.
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.
You can also mount the terminal base to a grounded
mounting plate. Refer to Panel/Wall Mount Grounding on
page 11.
DIN Rail Mounting
Use the steps below to mount the XM-944 terminal base unit on a DIN rail

IMPORTANT
IMPORTANT
ATTENTION
A Class 2 circuit can be provided by use of an NEC Class 2
rated power supply, or by using a SELV or PELV rated
power supply with a 5 Amp current limiting fuse installed
before the XM module(s).
24Vdc needs to be wired to terminal 37 (+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 4-20 mA Outputs
The XM-361 and XM-362 include six 4-20 mA output channels into a
maximum load of 600 ohms each. The 4-20 mA outputs are arranged into two
isolated banks of three outputs each. Each bank of 4-20 mA outputs is
electrically isolated from the other bank and from circuit power and ground.
The isolation provided is up to 250 V.
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 57 for a description of the 4-20 mA parameters.
Wire the 4-20 mA outputs to the terminal base unit as shown in Figure 2.9 and
Figure 2.10.
ATTENTION
Publication GMSI10-UM008D-EN-P - August 2010
The 4-20 mA output shields must be grounded at a single
point. It is recommended that where possible the cable
shield be grounded at the equipment wired to the 4-20 mA
output and not at the XM terminal base.

Connecting a Remote Relay Reset Signal
If you set the 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 the relay remotely after you have corrected the
alarm condition.
The Temperature modules do not have an on-board relay. The relays are added
when an Expansion Relay (XM-441) module is connected to the Temperature
modules. The XM-361 and XM-362 modules support two Expansion Relay
modules for a total of eight relays.
IMPORTANT
You must enable the Enable Relay Reset Switch
Terminals parameter to make the Channel 6 input
terminals available to wire the external relay reset switch.
Refer to General Parameters on page 48.
The module provides remote reset functionality by setting
the Channel 6 4-20 mA output to a fixed (12 mA) level, and
setting the Channel 6 input channel to measure that
current. The switch is wired in series to allow the current to
flow, or to break the flow.
TIP
TIP
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 a relay using the serial or remote
configuration tool.
Wire the Remote Relay Reset Signal to the terminal base (Channel 6 input,
Channel 6 4-20 mA output terminals) as shown in Figure 2.11. You must
attach an external current sensing resistor of 1 ohm, 1%, 1/4 W (for example,
KOA, part no. MF1/4CL1R00F) to the terminal base. Because the value is
low, the resistor must be wired directly on the terminal block, as shown
in Figure 2.11, to prevent wire resistance errors.

ATTENTION
The switch power supply is isolated, but shares common
with Channel 4 and Channel 5 4-20 mA outputs. Care
should be taken as to how these are grounded, if at all.
A single switch contact can also be shared by multiple Temperature modules
wired in series as shown in Figure 2.12. When multiple modules are wired to a
single switch, only one 4-20 mA output channel is necessary to supply all the
modules
ATTENTION
IMPORTANT
TIP
The relay reset connections may be different for different
XM modules. Figure 2.12 applies only to the XM-361 and
XM-362 modules. Refer to the installation instructions for
the module for its terminal assignments.
The XM-360/361/362 relay reset signal is not compatible
with other XM module’s relay reset input. Use of a single
switch requires a multi-pole switch. Refer to the XM
Module User Manual for more information about the other
XM modules.
Up to 24 XM-361/362 modules can be wired in series in a
single loop.

You may ground the cable shield at either end of the cable.
Do not ground the shield at both ends. When using an
ungrounded thermocouple, the shield must be connected
to ground at the module end.
When using grounded and/or exposed thermocouples that
are touching electrically conductive material, the potential
of any channel cannot exceed ±3V dc of the XM-361
power supply ground, or temperature readings will be
inaccurate.

Connecting a 3-Wire RTD
The XM-361 has variable gain circuitry that delivers the best possible range
and resolution for a given application. This is mostly determined by the
configuration’s input range. However, in the case of RTD lead wire detection,
these circuit settings are determined at power-up and are based off the actual
field wiring conditions. Therefore, any significant increase in field wiring
resistance that occurs after circuit power is applied may cause measurement
error.
Figures 2.14 to 2.19 show the wiring of 3-wire RTDs to the terminal base unit
of the XM-361 module.
ATTENTION
TIP
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 XM-361
terminal base and not at the field device. Any convenient
Chassis terminal may be used (see Terminal Block
Assignments on page 18).
When the XM-361 module is configured for an RTD on
every channel, the cold junction temperature is determined
from an on-board sensor inside the module, NOT the
sensors inside the terminal block.

XM-362 Module Sensor Wiring
The XM-362 accepts inputs only from Thermocouples. All six input channels
are electrically isolated from each other and from circuit power and ground.
The isolation provided is up to 250 V.
IMPORTANT
With all the cable shields connected (six individual input
cables and six output cables), there are not enough chassis
terminals for each shield. Therefore, the cable shields
should be paired as depicted in the following illustrations.
Recommended practice is to use a crimp ferrule.
Alternatively, you can use a separate grounding block
mounted next to the module.
Figure 2.32 shows the wiring of thermocouples to the terminal base unit of the
XM-362 module.

You may ground the cable shield at either end of the cable.
Do not ground the shield at both ends. When using an
ungrounded thermocouple, the shield must be connected
to ground at the module end.
39
IMPORTANT
IMPORTANT
When using grounded and/or exposed thermocouples that
are touching electrically conductive material, the ground
potential between any two channels cannot exceed +250
Volts. Exceeding this voltage could cause permanent
damage.
Inside the XM-361 and XM-362 terminal bases are cold
junction sensors used to determine the thermocouple
measurements. These sensors have intelligent diagnostics
that can determine cold junction out-of-range (OOR)
conditions and hardware failures.
A cold junction OOR condition can be monitored in the
configuration software (Cold Junction Status in XM
Serial Configuration Utility and Cold Junction
Overrange/Underrange in EDS file). It also sets bit 8
(Minor Recoverable Fault) of the Identity Object Status
Attribute.
A hardware failure at one of the cold junction sensor sets
bit 9 (Minor Unrecoverable Fault) of the Identity Object
Status Attribute. The faulted sensor and its value will be
ignored. The nearest remaining sensor’s value will be used
instead.
For more information on the Identity Object Status
Attribute, refer to the Identity Object on page 84.
PC Serial Port Connection
The XM-361 and XM-362 include a serial connection that allows you to
connect a PC to it and configure the module’s parameters. The connection is
through a mini-connector that is located on top of the module, as shown in
Figure 2.33.
Figure 2.33 Mini-Connector
mini-connector
Publication GMSI10-UM008D-EN-P - August 2010
40
A special cable (Cat. No. 1440-SCDB9FXM2) is required for this serial
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
IMPORTANT
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 24V 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-361 and XM-362 include a DeviceNet™ connection that allows the
modules to communicate directly 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-361 or XM-362. 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.

To preclude this possibility, even unintentionally, it is
recommended that DeviceNet V+ be left unconnected.
ATTENTION
ATTENTION
ATTENTION
IMPORTANT
You must ground the DeviceNet shield at only one
location. Connecting the DeviceNet shield to terminal 46
will ground the DeviceNet shield at the XM module. If you
intend to terminate the shield elsewhere, do not connect
the shield to terminal 46.
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
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-361 and XM-362 is set by way of
“baud detection” (Autobaud) at power-up.
Publication GMSI10-UM008D-EN-P - August 2010
42
Mounting the Module
The XM-361 and XM-362 mount on the XM-944 terminal base unit, Cat. No.
1440-TB-E. You should mount the module after you have connected the
wiring on the terminal base unit.
ATTENTION
The XM-361 and XM-362 are compatible only with the
XM-944 terminal base unit. The keyswitch on the terminal
base unit should be at position 5 for the modules.
Do not attempt to install XM-361 and XM-362
modules on other terminal base units.
Do not change the position of the keyswitch after
wiring the terminal base.
ATTENTION
WARNING
IMPORTANT
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.
Install the overlay slide label to protect serial connector and
electronics when the serial port is not in use.
1. Make certain the keyswitch (A) on the terminal base unit (C) is at
position 5 as required for the XM-361 and XM-362 modules.
Publication GMSI10-UM008D-EN-P - August 2010
43
2. Make certain the side connector (B) is pushed all the way to the left. You
cannot install the module unless the connector is fully extended.
3. Make sure that the pins on the bottom of the module are straight so they
will align properly with the connector in the terminal base unit.
4. Position the module (D) with its alignment bar (E) aligned with the
groove (F) on the terminal base.
5. Press firmly and evenly to seat the module in the terminal base unit. The
module is seated when the latching mechanism (G) is locked into the

Relay Parameters
The Relay parameters control the operation of the relays. The Temperature
modules do not have an on-board relay. The relays are added when an
Expansion Relay (XM-441) module is connected to the Temperature modules.
The XM-361 and XM-362 support two Expansion Relay modules for a total of
eight relays. Use these parameters to configure which alarm(s) the relay is
associated with, as well as the behavior of the relay.
IMPORTANT
Publication GMSI10-UM008D-EN-P - August 2010
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.

Failsafe Relay
Failsafe
Option
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.
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 4-20 mA
output signals. The XM-361 and XM-362 support a total of six 4-20 mA
outputs. Each output is permanently associated with a corresponding channel.
The parameters are the same for each output.
IMPORTANT
If the Enable Relay Reset Switch Terminals parameter
is enabled, Channel 6 is not available for configuration, and
the Channel 6 4-20 mA output is set to a fixed (12 mA)
level. See page 24 and page 48 for details.

Max Range
The measured value associated with the 20 mA.
IMPORTANT
Same measurement unit as
Temperature Units selection.
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-UM008D-EN-P - August 2010
58
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
above).
• The module is in Program mode.
• A sensor-out-of-range error occurs that affects the
corresponding measurement.
Triggered Trend Parameters
The XM-361/362 modules 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 module continuously monitors
the trended measurements. When a trigger occurs, the XM module collects
additional data as specified by the Post Trigger parameter.
The XM-361/362 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
Publication GMSI10-UM008D-EN-P - August 2010

trend records, the interval between trend records, and which relay triggers

Latch Enable
Determines whether the trigger trend is latched or
unlatched.
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 Number
Sets 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 52.

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 XM module, use the Device Mode
parameter in the EDS file. Note that the Stop and Start services described on
page 73 can also be used to change the operation mode.
IMPORTANT
71
The XM Serial Configuration Utility software automatically
puts XM modules in Program mode and Run mode
without user interaction.
Publication GMSI10-UM008D-EN-P - August 2010
72
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 73 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
EDS device parameters.
TIP
Publication GMSI10-UM008D-EN-P - August 2010
You can also use the Start service described on page 73 to
transition XM modules to Run mode.

The XM-361 and XM-362 modules support Poll, Change of State (COS),
Bit-Strobe I/O messages. The Poll response message is used by the XM
modules to produce measured values, and the COS message is used to produce
the Alarm and Relay Status. The Bit-Strobe message is used by a master device
to send a trigger event to all the XM slaves on the network.
Poll Message Format
The XM-361 and XM-362 Poll request message contains no data. The Poll
response message can contain up to 31 REAL values for a total of 124 bytes.
The XM-361 and XM-362 provide three pre-defined (static) data formats of
the Poll response, as defined in Assembly instance 101–103. It also provides a
dynamic Assembly instance, instance 199, with which you can define a custom
data format for the Poll response. The dynamic Assembly instance can contain
any of the measurement parameters included in Assembly instance 101, as well
as several of the alarm and relay configuration parameters.
The default Assembly instance is 101 and the default size is 48 bytes. You can
change the Assembly instance and define the dynamic Assembly using the
configuration software. Refer to I/O Data Parameters on page 61.
Publication GMSI10-UM008D-EN-P - August 2010
76
The Poll response data can also be requested explicitly through Assembly
Object (Class ID 0x4), Instance 101 (0x65) – 103 (0x67), Data Attribute (3).

Bit-Strobe Message Format
The Bit-Strobe command sends one bit of output data to each XM slave
whose node address appears in the master’s scanlist.
The Bit-Strobe command message contains a bit string of 64 bits (8 bytes) of
output data, one output bit per node address on the network. One bit is
assigned to each node address supported on the network (0...63) as shown in
Figure B.1.
Publication GMSI10-UM008D-EN-P - August 2010
79
Figure B.1 Bit-Strobe Command
The XM modules use the bit received in a Bit-Strobe connection as a trigger
event. When the bit number corresponding to the XM module’s node address
is set, the XM module will collect the triggered trend data.
Note that the XM modules do not send data in the Bit-Strobe response.
ADR for XM Modules
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.
IMPORTANT
It is recommended that ADR not be used in safety related
applications. If the failure of the ADR server, and a subsequent power cycle, would result in the loss of protection for
a machine, then ADR should not be implemented.
ADR can be used with XM modules but keep the following in mind when
setting up the XM modules.
Publication GMSI10-UM008D-EN-P - August 2010
80
• 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 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. These configuration parameters will not be
restored with ADR.
Below is a list of the configuration parameters that are not included in
the EDS file and can not be saved or 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.

Setting the MAC ID causes the device to reset automatically, after which it will go online with the new MAC
ID.
2
The Baud Rate setting can be set while Autobaud Disable is equal to 0. The new baud rate will not take
effect until the module is reset.
The MAC ID, BAUD Rate, and Autobaud Disable settings are stored in
non-volatile memory so they do not reset to the default with each power cycle.
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
rate detection instead. This means that the module will determine the network
baud rate by listening for network traffic before attempting to go online.

The dynamic Assembly instance must be instantiated with a call to the class
level Create service. Then the structure can be defined with the
Set_Attribute_Single service for the Member List attribute. Only one dynamic
Attribute instance is supported so subsequent calls to the Create service will
return a Resource Unavailable (0x02) error. The Delete service can be used to
destroy the dynamic Assembly instance so that it can be re-created.

The Parameter Object provides the interface to the XM-361 and XM-362
configuration data. There are 38 Parameter Object instances implemented in
the XM-361 and XM-362 modules.
Parameter Object
(Class ID 0FH)
Parameter Object instances 1-22 and 31-36 are implemented to provide an
alternate method of setting the configuration parameters with EPATH or
ENGUNIT data types. And Parameter Object instances 23 and 24 provide an
alternate method of 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.

The Poll Connection Produced Connection Path and Size parameters cannot be set while the Poll Connection is
already established with a master/scanner. Attempting to do so will result in an "Object State Conflict" error
(error code 0XC). These Parameter instances are a little more flexible than the actual Connection Object
attributed because they can be set while the connection is in the NON-EXISTENT state (before the
master/scanner allocates the connection).

Glossary
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).
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
125 K
250 K
500 K
Thick Trunk Line
500 m (1,640 ft.)
250 m (820 ft.)
100 m (328 ft.)
Thin Trunk Line
100 m (328 ft.)
100 m (328 ft.)
100 m (328 ft.)
Maximum Drop Length
6 m (20 ft.)
6 m (20 ft.)
6 m (20 ft.)
Cumulative Drop Length
156 m (512 ft.)
78 m (256 ft.)
39 m (128 ft.)
The XM measurement modules’ baud rate is automatically set by the bus
master. You must set the XM-440 Relay module baud rate. You set the
XM-440 Master Relay to 125 kb, 250 kb, 500 kb, or Autobaud if another device
on the network has set the baud rate.
Bit-Strobe
A multicast transfer of data sent by a master device to all the XM slaves on the
network. The bit-strobe command message contains a bit string of 64 bits (8
bytes) of output data, one output bit per node address on the network.
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.
111
Publication GMSI10-UM008D-EN-P - August 2010
112
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
parameters in the XM module’s memory. When power is cycled, the current
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.
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.
Publication GMSI10-UM008D-EN-P - August 2010
113
• 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.
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.
Publication GMSI10-UM008D-EN-P - August 2010
114
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 Dynamic Measurement module and the XM-361
Temperature module.
Strobe
See Bit-Strobe.
trend
A set of records of one or more measurement parameter(s) collected at regular
intervals of a base parameter such as time.
triggered trend
A time-based trend that is collected in an XM module when a relay on the XM
module is activated, or when the module receives a trigger event.
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, PLC, or an XM-440 Master Relay module (firmware
revision 5.0 and later).
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.
