Introducing the XM-361 and XM-362 Modules

The XM-361 Universal Temperature module and the XM-362 Isolated Thermocouple Temperature module are members of the Allen-Bradley™

XM 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.

Series, a family of DIN rail mounted condition monitoring and

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 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

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.

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).

Publication GMSI10-UM008D-EN-P - August 2010

IMPORTANT

ATTENTION

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.

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.

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.

IMPORTANT

To Ground Bus

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.

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.

Figure 2.6 Grounded DeviceNet V- at XM Module

Publication GMSI10-UM008D-EN-P - August 2010

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.

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 (A-B pt no. 199-DR1 or 199-DR4).

Publication GMSI10-UM008D-EN-P - August 2010

1. Position the terminal base on the 35 x 7.5 mm 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.

Connecting the Power Supply

The power supply to the module is nominally 24V dc (±10%) and must be a Class 2 rated circuit.

Wire the DC-input power supply to the terminal base unit as shown in Figure

2.8.

Publication GMSI10-UM008D-EN-P - August 2010

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.

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.

TIP

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.

You must enable the Enable Relay Reset Switch Ter mi na ls 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.

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.

Figure 2.11 Remote Relay Reset Signal Connection

ATTENTION

IMPORTANT

TIP

1Ω, 1%, 1/4 or 1/2 W resistor

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

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.

XM-361 Module Sensor Wiring

The XM-361 accepts inputs from Thermocouples and 2-wire and 3-wire RTDs. Note that all six channels can be any mix of RTDs and thermocouple inputs.

Connecting a Thermocouple

Figure 2.13 shows the wiring of thermocouples to the terminal base unit of the XM-361 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.

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.

ATTENTION

TIP

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.

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.

ATTENTION

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.

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.

Figure 2.32 Thermocouple to XM-362 Wiring

Publication GMSI10-UM008D-EN-P - August 2010

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.

IMPORTANT

mini-connector

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

Publication GMSI10-UM008D-EN-P - August 2010

WARNING

IMPORTANT

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.

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.

Connect To Terminal Base Unit

Red Wire DNet V+ 47 (Optional - see note) White Wire CAN High 44 Bare Wire Shield (Chassis) 46 Blue Wire CAN Low 45 Black Wire DNet V- 48

Publication GMSI10-UM008D-EN-P - August 2010

IMPORTANT

ATTENTION

IMPORTANT

The DeviceNet power circuit through the XM module interconnect, which is rated at only 300 mA, is not intended 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.

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.

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

ATTENTION

WARNING

IMPORTANT

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.

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.

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

Module Indicators

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 module.

6. Repeat the above steps to install the next module in its terminal base.

Module Indicators

Each Temperature module has eight LED indicators, which include a module status (MS) indicator, a network status (NS) indicator, and a status indicator for each channel (CH1 to CH6). The LED indicators are located on top of the module.

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.

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.

Relay Parameters

Parameter Name Description Options/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.

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.

Publication GMSI10-UM008D-EN-P - August 2010

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.

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.

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.

4-20 mA Parameters

Parameter Name Description Options/Comments 4-20mA Output (XM Serial

Configuration Utility only) Enable Enables/disables the 4-20 mA output.

Sets the 4-20 mA output to be configured in the XM Serial Configuration Utility.

Each output is associated with a corresponding channel.

Measurement Sets the measurement value that the 4-20 mA output

will track.

Min Range The measured value associated with the 4 mA. Same measurement unit as Max Range The measured value associated with the 20 mA.

Options: Value

Difference

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

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

the module.

Check to enable. Clear to disable.

More than one measurement can be selected.

Number of Records The maximum number of measurement sets that can

be collected in the trend buffer. The measurement sets make up the trend data.

Latch Enable Determines whether the trigger trend is latched or

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

Record Interval The amount of time between consecutive trend

records.

The Number of Records is automatically calculated based upon the number of Trended Measurements selected.

Interval).

Note: If you edit the Trend Span, the Record Interval is automatically updated.

Seconds

Triggered Trend Parameters

Parameter Name Description Values/Comments Post Trigger The percentage of records to be collected once the

0 to 100 Percent trigger occurs. For example, if you set Post Trigger to 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.

Status Shows the status of the trend data. Possible status values:

• Not collected - No trend data is currently collected.

• Collecting - A trigger has occurred and data (including post-trigger data) is being collected.

• Collected - A trend has been saved to the buffer and is available to view and upload.

View Trend Data Displays a plot of the collected trend data. Reset Trigger Resets the trigger if Latch enabled is selected. This

allows the module to overwrite the previous trend data when the next trigger occurs.

Manual Trigger Triggers the module to collect the trend data without

relay activation.

Appendix

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.

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.

The XM Serial Configuration Utility software automatically puts XM modules in Program mode and Run mode without user interaction.

TIP

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 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.

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.

XM-361/362 I/O Message Formats

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

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

IMPORTANT

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.

ADR for XM Modules

Note that the XM modules do not send data in the Bit-Strobe response.

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.

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

TIP

• 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.

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.

Publication GMSI10-UM008D-EN-P - August 2010

– Channel Name – Tachometer Name – Alarm Name – Relay Name – All Triggered Trend related parameters (see page 58)

– All SU/CD Trend related parameters – Custom Assembly structure (see page 61)

• 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 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.

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.
