Introduction

This chapter provides an overview of the XM-220 Dual Speed module. It also discusses the components of the module.

Introducing the XM-220 Module

The XM-220 Dual Speed 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-220 is a two channel module that accepts input from any two tachometers of any standard type including eddy current probes, magnetic pickups, optical tachometers, and TTL output devices. It measures speed, rotor acceleration, and peak speed and is capable of detecting zero speed, locked rotor, and reverse rotation conditions. It is also used as a component of the XM Electronic Overspeed Detection system.

The XM-220 can be configured (using the configuration software) to operate in three different modes. This controls how the sensors are used to calculate the speed, acceleration, and peak measurements.

• Dual Channel Mode - This is the default mode. The two sensors are

used independently to perform two separate sets of speed, acceleration, and peak speed measurements.

• Single Redundant Channel Mode- One of the two sensors is used

perform the speed, acceleration, and peak speed measurements. The module automatically switches to the other (redundant) sensor when a transducer or tachometer fault is detected on the current sensor.

• Reverse Rotation Mode - The two sensors are used to monitor speed

and direction of a single shaft. The two sensors must be mounted out of phase from each other so that the rotational direction can be determined by monitoring which sensor the shaft keyway passes first. Refer to Sensor Placement for Reverse Rotation on page 35.

XM-941 Speed/Position Module

Terminal Base Unit Cat. No. 1440-TB-B

XM-220 Dual Speed Module

Cat. No. 1440-SPD02-01RB

The module includes a single on-board relay (expandable to five), two 4-20mA outputs, and a buffered output for each input. A third buffered output is available when the module is functioning in the single redundant channel mode. This buffered output signal corresponds to the active input signal so that the machine speed can be accurately tracked regardless of which of the redundant sensors is active.

The XM-220 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-220 Module Components

The XM-220 module consists of a terminal base and an instrument module. The XM-220 Dual Speed module and the XM-941 Position/Speed Terminal Base are shown below.

Introduction 3

IMPORTANT

• XM-220 Dual Speed Module - Mounts on the XM-941 terminal base

unit via a keyswitch and a 96-pin connector. The XM-220 contains the measurement electronics, processor, relay, and serial interface port for local configuration.

The XM-441 Expansion Relay module may be connected to the XM-220 module via the XM-941 terminal base unit.

When connected to the XM-220, the Expansion Relay module simply “expands” the capability of the XM-220 by adding four additional epoxy-sealed relays. The XM-220 controls the Expansion Relay module by extending to it the same logic and functional controls as the XM-220 module’s on-board relay.

XM Installation Requirements

This section describes wire, power and grounding requirements, and instructions 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

• Recommended strip length 8 millimeters (0.31 inches)

• Minimum insulation rating of 300V

• 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.

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 3A. 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 3A.

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

24V Common Grounding

24V power to the XM modules Must be grounded. When two or more power supplies power the XM system, ground the 24V 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 24V 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. See 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

Figure 2.6 Grounded DeviceNet V- at XM Module

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 measurement modules. The XM-941 terminal base, Cat. No. 1440-TB-B, is the only terminal base unit used with the XM-220.

22 Installing the XM-220 Dual Speed Module

IMPORTANT

TIP

IMPORTANT

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 53 for details.

Table 2.1 shows the on-board relay connections for the module.

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 XM-220 to provide additional relays. Refer to 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.

Connecting the Buffered Outputs

The XM-220 provides buffered outputs of all transducer input signals. The buffered output connections may be used to connect the module to portable

data collectors or other online systems.

Figure 2.13 shows the buffered output connections for the module.

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.

Installing the XM-220 Dual Speed Module 25

Connecting the Switched Buffered Output

The XM-220 can be configured to automatically switch to a second (redundant) sensor when a transducer or tachometer fault is detected on the current sensor. When the module is functioning in redundant mode, it provides a third buffered output which outputs a signal corresponding to the active input signal. This allows you to accurately track the machine speed regardless of which of the redundant sensors is active. The signal from the

switched buffered output is a CMOS (0 to 5 volt) level square-wave.

Page 34

26 Installing the XM-220 Dual Speed Module

IMPORTANT

TIP

The XM-220 switched buffered output can be connected to as many as 19 XM-12X modules, which includes the XM-120, XM-121, XM-122, and XM-123 modules. Figure 2.14 shows the switched buffered output connection to an XM-12X module.

Figure 2.14 Switched Buffered Output

To invert the input signal, connect a jumper from terminal 20 (Switched Buffer -), instead of terminal 4, on the XM-220 terminal base to terminal 4 (Tach/Signal In +) on the XM-12X terminal base.

Make certain to set the Measurement Mode parameter to "Single Redundant Channel." Refer to Measurement Mode Parameter on page 46.

When the Measurement Mode parameter is set to either "Dual Channel" or "Reverse Rotation," the Switched Buffer output will correspond to channel 1 input.

Connecting the 4-20mA Outputs

The module includes an isolated 4-20mA per channel output into a maximum load of 300 ohms. The measurements that the 4-20mA output tracks and the signal levels that correspond to the 4mA and 20mA are configurable. Refer to 4-20mA Output Parameters on page 58.

Wire the 4-20mA outputs to the terminal base unit as shown in Figure 2.15.

Publication GMSI10-UM004B-EN-P - May 2010

Page 35

Figure 2.15 4-20mA Output Connections

ATTENTION

TIP

The 4-20mA outputs are functionally isolated from other circuits. It is recommended that the outputs be grounded at a single point. Connect the 4-20mA (-) to the XM terminal base (Chassis terminal) or directly to the DIN rail, or ground the signal at the other equipment in the 4-20mA loop.

Installing the XM-220 Dual Speed Module 27

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-220.

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

Connecting the Transducer

The XM-220 can accept input signals from any Allen-Bradley non-contact eddy current probe, magnetic pickups, or TTL output devices.

Active magnetic speed sensors or eddy current probes are often used on machines where rotational speeds below 250 rpm must be reliably sensed, for example reverse rotation and zero speed applications. Passive magnetic speed sensors do not typically generate a suitable signal at slow shaft rotational speeds. To sense shaft rotation speeds down to 1 rpm, active magnetic speed sensors or eddy current probes are required.

PC Serial Port Connection

The XM-220 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.

WARNING

IMPORTANT

• Mini-Connector - The mini-connector is located on the top of the

module, as shown below.

Figure 2.27 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 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-220 includes a DeviceNet™ connection that allows the modules 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-220. As multiple XM modules are interconnected, DeviceNet also serves as the communication bus and protocol that efficiently transfers data between the XM modules.

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 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).

Mounting the Module

The XM-220 mounts on the XM-941 terminal base unit, Cat. No. 1440-TB-B. We recommend that you mount the module after you have connected the wiring on the terminal base unit.

The XM-220 module is compatible only with the XM-941 terminal base unit. The keyswitch on the terminal base unit should be at position 4 for the module.

Do not attempt to install XM-220 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.

Measurement Mode Parameter

The Measurement Mode parameter controls how the two sensors are used to calculate the speed, acceleration, and peak measurements. The XM-220 module operates in three different modes:

• Dual Channel - This is the default mode. The two sensors are used

independently to perform two separate sets of speed, acceleration, and peak speed measurements.

• Single Redundant Channel - One of the two sensors is used to

The Speed, Acceleration, and Peak Speed measurements are measured only on channel 1. Channel 2 measurements (Speed, Acceleration, and Peak Speed) are not measured.

• Reverse Rotation - The two sensors are used to monitor both speed

and direction. The two sensors must be mounted out of phase from each other so that the rotational direction can be determined by monitoring which sensor the shaft keyway passes first. Refer to Sensor Placement for Reverse Rotation on page 35.

Channel 1 measures the Speed, Acceleration, and Peak Speed in the forward direction. Channel 2 measures the Speed, Acceleration, and Peak Speed in the reverse direction.

TIP

IMPORTANT

Channel Tachometer Parameters

The Tachometer parameters define the characteristics of the tachometer and determine the signal processing that will be performed on the tachometer signal. There are two instances of the tachometer parameters, one for each channel.

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 setting 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.

If you are not using the tachometer channel, set the Pulses per Revolution to zero. This will disable the tachometer measurement, and prevent the module from indicating a tachometer fault.

In Single Redundant Channel mode and Reverse Rotation mode, the Pulses Per Revolution must be non-zero for both channels. Redundancy or reverse rotation detection will be impossible if either tachometer is disabled.

In Reverse Rotation mode, the value entered in Pulses Per Revolution must be equal for both channels. And the value entered in Speed Multiplier must be the equal for both channels.

Controls whether a small amount of current is injected into the sensor wiring to help detect transducer faults of passive magnetic sensors.

Passive magnetic sensors are unbiased and provide no inherent fault detection capability. The XM-220 is able to detect an open or short circuit from the input to the sensor using the resistance of the passive magnetic sensor and a configurable bias current per channel. To use this feature, the resistance of the magnetic sensor must be a minimum of 350 ohms. In an open circuit situation, the Transducer DC bias measurement will read approximately 18 volts. In a short circuit situation, the Transducer DC bias will read near 0 volts. Under normal operating conditions,

Parameter Name Description Values/Comments Startup Period The length of time that the tachometer fault is

inhibited after the startup period. The startup period begins when the startup switch is reopened (push button disengaged or toggle switch flipped to off).

Inhibit Tachometer Fault Controls whether to inhibit the tachometer fault

during the startup period.

During startup, the machine may be turning very slowly and cause the XM module to detect a tachometer fault. The Alarm status will state that a tachometer fault condition exists unless the tachometer fault is inhibited.

Enter a value from 0 to 1092 minutes,

adjustable in increments of 0.1

minutes.

Note: This parameter is not applicable

for Locked Rotor alarms.

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.

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.

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.

4-20mA Output Parameters

The 4-20mA output parameters define the characteristics of the two 4-20mA output signals. The parameters are the same for each output.

4-20mA Parameters

Parameter Name Description Options/Comments Enable Enables/disables the 4-20mA output.

Measurement Sets the type of measurement and the channel that

the 4-20mA output signal will track.

Min Range The measured value associated with the 4mA. RPM for Speed Max Range The measured value associated with the 20mA.

Options: Channel 1 Speed

RPM/min for Acceleration

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.

Channel 2 Speed Channel 1 Acceleration Channel 2 Acceleration

Publication GMSI10-UM004B-EN-P - May 2010

The 4-20mA outputs are either on or off. When they are on, the 4-20mA outputs overshoot the 4 and 20mA limits by 10% when the measurement exceeds the minimum and maximum range. This means the minimum current produced is 3.6mA and the maximum current produced is 22mA.

When the 4-20mA outputs are off, they produce a current approximately 2.9mA. The 4-20mA outputs are off under the following conditions:

• The 4-20mA outputs are set to "Disable" (see Enable above).

• The module is in Program mode.

• A transducer fault or tachometer fault occurs that affects

the corresponding measurement.

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 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.

XM-220 I/O Message Formats

The XM-220 module supports Poll and Change of State (COS) 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.

Poll Message Format

The XM-220 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-220 provides 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 32 bytes. You can change the Assembly instance and define the dynamic Assembly using the configuration software. Refer to I/O Data Parameters on page 59.

The Poll response data can also be requested explicitly through Assembly Object (Class ID 0x4), Instance 101 (0x65), Data Attribute (3).

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.

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-UM004B-EN-P - May 2010

Page 87

DeviceNet Information 79

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 mode after the configuration is downloaded by the ADR scanner.

• The ADR scanner saves and restores only the configuration parameters

contained in the module’s EDS file. Some XM parameters are not included in the EDS file because they are not supported by either the EDS specification or the tools that read the EDS files, for example RSNetWorx for DeviceNet. 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.

– Channel Name

– Tachometer Name

– Alarm Name

– Relay Name

– All Triggered Trend related parameters

Publication GMSI10-UM004B-EN-P - May 2010

Page 88

80 DeviceNet Information

– All SU/CD Trend related parameters

– Custom Assembly structure (see page 59)

• 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.

• 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
