1-2 Installing Your DeviceNet Adapter Module

Module Installation

Compact I/O is suitable for use in an industrial environment when installed in accordance with these instructions. Specifically, this equipment is intended for use in clean, dry environments (Pollution

degree 2 60664-1).

1. Pollution Degree 2 is an environment where, normally, only non-conductive pollution occurs except that

occasionally a temporary conductivity caused by condensation shall be expected.

2. Over Voltage Category II is the load level section of the electrical distribution system. At this level transient

voltages are controlled and do not exceed the impulse voltage capability of the product’s insulation.

3. Pollution Degree 2 and Over Voltage Category II are International Electrotechnical Commission (IEC)

designations.

) and circuits not exceeding Over Voltage Category II2 (IEC

Prevent Electrostatic Discharge

ATTENTION

Electrostatic discharge can damage integrated circuits or semiconductors if you touch bus connector pins or the terminal block. Follow these guidelines when you handle the module:

• Touch a grounded object to discharge static potential.

• Wear an approved wrist-strap grounding device.

• Do not touch the bus connector or connector pins.

• Do not touch circuit components inside the module.

• If available, use a static-safe work station.

• When not in use, keep the module in its static-shield box.

System Configuration

Remove Power

ATTENTION

Remove power before removing or inserting this adapter. When you remove or insert an adapter with power applied, an electrical arc may occur. An electrical arc can cause personal injury or property damage by:

• sending an erroneous signal to your system’s field devices,

causing unintended machine motion

• causing an explosion in a hazardous environment

Electrical arcing causes excessive wear to contacts on both the module and its mating connector. Worn contacts may create electrical resistance.

Refer to Using Banks of I/O on page 3-7 for system configuration rules.

Installing Your DeviceNet Adapter Module 1-3

System Assembly

The adapter can be attached to adjacent 1769 modules before or after mounting. For mounting instructions, see “Panel Mounting” on page 1-4, or “DIN Rail Mounting” on page 1-6. To work with a system that is already mounted, see “Replacing the 1769-ADN within a System” on page 1-6. The following procedure shows you how to assemble the Compact I/O system.

1769-ADN

1. Disconnect power.

2. Check that the bus lever of the module to the right of the

1769-ADN is in the unlocked (fully right) position.

3. Use the upper and lower tongue-and-groove slots (a) to secure

the modules together.

42126

4. Move the module back along the tongue-and-groove slots until

the bus connectors line up with each other.

5. Push the bus lever of the module to the right of the 1769-ADN back slightly to clear the positioning tab (b) using your fingers or a small screwdriver.

6. To allow communication between the adapter and I/O modules, move the bus lever of the module to the right of the 1769-ADN fully to the left (c) until it clicks. Make sure it is locked firmly into place.

ATTENTION

When attaching a 1769-ADN adapter, it is very important that the bus connectors are securely locked together to create a proper electrical connection.

7. Attach an end cap terminator (d) to the last I/O module in the

system by using the tongue-and-groove slots as before.

Publication 1769-UM001B-EN-P - October 2002

1-4 Installing Your DeviceNet Adapter Module

8. Lock the end cap bus terminator (e).

Mounting the Adapter and an I/O Module

IMPORTANT

A 1769-ECR or 1769-ECL right or left end cap must be used to terminate the end of the serial communication bus.

9. Refer to the “DeviceNet Wiring” section on page 1-7.

ATTENTION

During panel or DIN rail mounting of all devices, be sure that all debris (metal chips, wire strands, etc.) is kept from falling into the adapter or modules. Debris that falls into the adapter or modules could cause damage on power up.

Minimum Spacing

Maintain spacing from enclosure walls, wireways, adjacent equipment, etc. Allow 50mm (2in) of space on all sides for adequate ventilation, as shown:

Panel Mounting Procedure Using Modules as a Template

The following procedure allows you to use the assembled adapter and modules as a template for drilling holes in the panel. If you have sophisticated panel mounting equipment, you can use the dimensional template provided on page 1-5.

Due to the module mounting hole tolerance, it is important to follow these procedures:

1. On a clean work surface, assemble no more than three modules.

2. Using the assembled modules as a template, carefully mark the

center of all module-mounting holes on the panel.

3. Return the assembled modules to the clean work surface, including any previously mounted modules.

4. Drill and tap the mounting holes for the recommended M4 or #8 screw.

5. Place the modules back on the panel and check for proper hole alignment.

6. Attach the modules to the panel using the mounting screws.

NOTE: If mounting more modules, mount only the last one of

this group and put the others aside. This reduces remounting time during drilling and tapping of the next group.

7. Repeat steps 1 through 6 for any remaining modules.

Publication 1769-UM001B-EN-P - October 2002

1-6 Installing Your DeviceNet Adapter Module

DIN Rail Mounting

The adapter can be mounted using the following DIN rails:

• 35 x 7.5mm (EN50022 - 35 x 7.5)

• 35 x 15mm (EN 50022 - 35 x 15)

Before mounting the module on a DIN rail, close the DIN rail latches. Press the DIN rail mounting area of the module against the DIN rail. The latches will momentarily open and lock into place.

Replacing the 1769-ADN within a System

The adapter can be replaced while the system is mounted to a panel (or DIN rail).

1. Remove power. See important note on page 1-2.

2. Remove the DeviceNet cable from the module by loosening the

upper and lower retaining screws of the DeviceNet connector and removing the connector from the module.

3. Remove the upper and lower mounting screws from the adapter (or open the DIN latches using a flat-blade or phillips-style screwdriver).

4. On the right-side adjacent module, move its bus lever to the right (unlock) to disconnect it from the adapter being removed.

5. Gently slide the disconnected adapter forward.

If you feel excessive resistance, make sure that you disconnected the adapter from the bus and that you removed both mounting screws (or opened the DIN latches).

Note: It may be necessary to rock the module slightly from front to back to remove it, or, in a panel-mounted system, to loosen the screws of adjacent modules.

Publication 1769-UM001B-EN-P - October 2002

6. Before installing the replacement adapter, be sure that the bus lever on the right-side adjacent module is in the unlocked (fully right) position.

7. Slide the replacement adapter into the open slot.

8. Connect the adapter and modules together by locking (fully left)

the bus lever on the right-side adjacent module.

9. Replace the mounting screws (or snap the adapter onto the DIN rail).

10. Replace the DeviceNet cable on the module by tightening the

upper and lower retaining screws and attaching the connector to the module.

Set the network address switches to the same value as the removed adapter.

Field Wiring Connections

Grounding the Adapter

This product is intended to be mounted to a well-grounded mounting surface such as a metal panel. Additional grounding connections from the adapter’s mounting tabs or metal DIN rail (if used), are not required unless you cannot ground the mounting surface. Refer to Industrial Automation Wiring and Grounding Guidelines, publication 1770-4.1, for additional information.

1-8 Installing Your DeviceNet Adapter Module

Setting the Network Address Switches

TIP

DeviceNet cable colors are shown on the wiring label on the front of the adapter.

Note: A 10-pin linear plug (i.e., 1787-PLUG10R) will not fit while a 1799-DNETCON or -DNETSCON will fit.

IMPORTANT

If the 1769-ADN is the last device connected to the DeviceNet network trunkline, be sure to add or move the termination resistor (Allen-Bradley part number 1485A-C2 or a 120

Ω 5% or > ¼W resistor)

across the Blue (CAN Low) and White (CAN High) wires. We recommend 121

Ω ¼W 1% metal film.

Set the network node address with the two rotary switches on the front of the module. Use a small, slotted screwdriver to set the switches. The switch labeled MSD (Most Significant Digit) sets the 10s digit while the switch labeled LSD (Least Significant Digit) sets the 1s digit.

Valid network node addresses are 00 through 63. Switch settings from 00 to 63 select network addresses 00 to 63. Switch settings from 64 to 99 instruct the adapter to use the software programmed value for the node network address. (Address 95 is reserved and should not be used for normal operation.)

Publication 1769-UM001B-EN-P - October 2002

The software programmed value is set via RSNetworx

for DeviceNet and stored in non-volatile memory on the 1769-ADN. The initial, factory-preset setting of the software programmed value is 63.

Installing Your DeviceNet Adapter Module 1-9

Use the removable, write-on label to mark your I.D. tag, etc. with permanent ink. Your markings are visible when the module door is closed.

Configuring the 1769-ADN

TIP

The 1769-ADN must be configured with RSNetworx for DeviceNet. This configuration tool allows you to identify all of the devices (I/O modules, power supplies, expansion cables, end caps) and their locations in your 1769 system. The 1769-ADN must have the I/O configuration loaded into its’ memory to perform the network communication function.

The 1769-ADN will not accept I/O connections if the programmed system configuration does not match the actual system configuration. The 1769-ADN retains the programmed system configuration in non-volatile memory so it can compare it with the actual system configuration on power-up. For more information, refer to Configuring Your Compact I/O Series A DeviceNet Adapter in Chapter 3 or Configuring Your Compact I/O Series B DeviceNet Adapter in Chapter 4.

Series B adapters that have their node address switches set to 95, startup in a special factory mode that does not support I/O connections. Series B adapters should not have their node address set to 95 for normal use.

Chapter

How Communication Takes Place and I/O Image Table Mapping

This chapter explains how communication takes place and about I/O image table mapping. Included is information about:

• I/O Structure

• Communication Choices

• Mapping I/O Data into the Image Table

Communication Over the 1769 Bus

I/O Structure

One 1769-ADN DeviceNet adapter can interface with up to 30 Compact I/O modules to make a Compact I/O system. The adapter communicates to other network system components (typically a controller or scanner and/or programming terminals) over the DeviceNet network.

The adapter communicates with its I/O modules over the 1769 bus. The adapter and I/O modules also receive 5Vdc and 24V dc power through the bus interface via a 1769 power supply. The 1769 bus and all devices on the 1769 bus have system configuration limits. Refer to Using Banks of I/O on page 3-7 for more information.

The I/O map for an I/O module is divided into input data words and output data words. The number of input data words or output data words can be 0 or more. The length of each I/O module’s input data words or output data words vary in size, depending on the module’s complexity. Each I/O module will support at least one input data word or one output data word.

Output data is received by the adapter in the order of the installed I/O modules. The output data for Slot 1 is received first, followed by the output data for Slot 2, and so on up to Slot 30.

The amount of output data in the adapter’s output image for each I/O module is based on the configuration of each I/O module done as part of the 1769-ADN configuration. If an I/O module is configured to have 0 words of output data, then it does not appear in the output image of the 1769-ADN. Only a module’s output data can be in the 1769-ADN output image - a module’s configuration data cannot.

The first two words of input data sent by the adapter are the Adapter Status Words. This is followed by the input data from each slot, in the order of the installed I/O modules. The input data from Slot 1 is first after the status words, followed by Input data from Slot 2, and so on up to Slot 30.

2-2 How Communication Takes Place and I/O Image Table Mapping

The amount of input data in the adapter’s input image for each I/O module is based on the configuration of each I/O module done as part of the 1769-ADN configuration. If an I/O module is configured to have 0 words of input data, then it does not appear in the input image of the 1769-ADN.

2-4 How Communication Takes Place and I/O Image Table Mapping

Communication Choices

The Compact I/O DeviceNet adapter module supports multiple communication choices. These choices all use the DeviceNet adapter input image and output image structure previously described. The DeviceNet master makes the actual communication choice. The choices are:

Polled

- data is sent by the adapter in response to received data

Strobe - data is sent by the adapter in response to the strobe command. The single bit allocated to the adapter in the strobe message is not used. If the configured size of the input image (sent from the adapter) is greater than 8 bytes, only the first 8 bytes of the input image are returned (of which, the first 4 bytes, or 2 words, are the adapter status words).

Change of State - data is sent by the adapter based on detection of any changed value within the input data. Data is independently received based on change of state from the sender. Data in both directions can be acknowledged or unacknowledged depending on the run time configuration of the system.

Cyclic - data is sent cyclically by the adapter based on a configured time value. Data is independently received cyclically from the sender. Data in both directions can be acknowledged or unacknowledged depending on the run time configuration of the system.

The output module’s input data file reflects the output data echo of the module, not necessarily the electrical state of the output terminals. It does not reflect shorted or open outputs.

It is important to use this input word if the controller adapter supports the Program Mode or Fault Mode function, and if it is configured to use them.

Sx = General status bit for channels 0-5 and CJC sensors (S6 and S7). This bit is set (1) when an error (over-range, under-range, open-circuit, or input data not valid) exists for that channel. An input data not valid condition is determined by the user program. This condition occurs when the first analog-to-digital conversion is still in progress, after a new configuration has been sent to the module. Refer to the Compact Thermocouple/mV Input Module User Manual, publication 1769-UM004A-EN-P for additional details.

OCx = Open circuit detection bits indicate an open input circuit on channels 0-5 (OC0 - OC5) and on CJC sensors CJC0 (OC6) and CJC1 (OC7). The bit is set (1) when an open-circuit condition exists.

Ux = Under-range flag bits for channels 0-5 and the CJC sensors (U6 and U7). For thermocouple inputs, the under-range bit is set (1) when a temperature measurement is below the normal operating range for a given thermocouple type. For millivolt inputs, the under-range bit indicates a voltage that is below the normal operating range. These bits can be used in the control program for error detection. The bits are reset (0) by the module when within the normal operating range.

Ox = Over-range flag bits for channels 0-5 and the CJC sensors (O6 and O7). For thermocouple inputs, the over-range bit is set (1) when a temperature measurement is above the normal operating range for a given thermocouple type. For millivolt inputs, the over-range bit indicates a voltage that is above the normal operating range. These bits can be used in the control program for error detection.

Refer to the Compact Manual, publication 1769-UM005A-EN-P for additional details.

OCx = Open circuit detection bits indicate an open input circuit on channels 0-5 (OC0 - OC5). The bit is set (1) when either an open or shorted input for RTD inputs or an open input for resistance inputs is detected.

Short-circuit detection for resistance inputs is not indicated because 0 is a valid number.

Ux = Under-range flag bits for channels 0-5, using RTD inputs only. These bits can be used in the control program for error detection. There is no under-range error for a direct resistance input, because 0 is a valid number.

Input words 6 and 7 contain the Output Data Echo/Loopback information for output channels 0 and 1 respectively. Bits 0 through 6 and bit 15 or words 6 and 7 should always be set to zero in your control program. If they are not set to 0, the invalid data flag (Ex) will be set for that channel by the module. However, the channel will continue to operate with the previously converted value.

1 All unused bits are set to 0 by the module.

SGN = Sign bit in two’s complement format. Always positive (equal to zero) for the 1769-IF4XOF2 module.

Ix = Over-range flag bits for input channels 0 through 3. These bits can be used in the control program for error detection. When set to 1, the bits signal that the input signal is outside the normal operating range. However, the module continues to convert analog data to the maximum full-range value. When the over-range condition is cleared, the bits are automatically reset (0).

Ox = Word 5, bits 0 and 1, provide over-range indication for output channels 0 and 1. These bits can be used in the control program for error detection. When set to 1, the bits signal that the output signal is outside the normal operating range. However, the module continues to convert analog data to the maximum full-range value. When the over-range condition is cleared, the bits are automatically reset (0). Under-range indication is not provided

because zero is a valid number.

Ex = When set (1), this bit indicates that invalid data (e.g. the value sent by the controller is outside the standard output range or increment; e.g. 128, 256, etc.) has been set in the output data bits 0 through 6, or the sign bit (15).

Hx = Hold Last State bits. When set (1), these bits indicate that the channel is in a Hold Last State condition.

Words 6 and 7 = These words reflect the analog output data echo of the analog value being converted by the digital/analog converter, not necessarily the electrical state of the output terminals. They do not reflect shorted or open outputs.

It is only important to use the loopback function of input words 6 and 7 if the controller supports the Program Mode or Fault Mode functions, and if it is configured to use them.

Output Data

The output data file applies only to output data from the module as shown in the table below.

IMPORTANT

Bits 0 through 6 and bit 15 of output data words 0 and 1 should always be set to zero in your control program. If they are not set to 0, the invalid data flag (Ex) will be set for that channel. However, the channel will continue to operate with the previously converted value. If a MVM (Move with Mask) instruction is used with a mask of 7F80 (hexidecimal) to move data to the output words, writing to bits 0 through 6 and bit 15 can be avoided.

The Output Array, which consists of 34 words, allows you to access the module’s real-time output data to control the module. The default value is all zeros.

IMPORTANT

The Output Array contains dynamic configuration data. The settings in the Output Array must be compatible with the settings in the Configuration Array.

For example, do not attempt to set Counter Control Bits for a given counter in the Output Array unless NumberOfCounters in the Configuration Array indicates that the counter is declared to be used.

All Not Used bits (shaded in the table below) must be set to 0 or the InvalidOutput bit in the Input Array will be set. When the InvalidOutput bit is set, the entire Output Array is rejected until an Output Array that does not have this error is sent.

(words)

Factory defaults (for size) set I/O sizes to the maximum amount of I/O data for a module to provide maximum functionality. You can change the I/O data size for a module by reducing the number of words mapped into the adapter module.

The real-time settings option provides optimal real time data to and from the I/O module over the network. You need a software configuration tool to change the size. The real time settings provide the fastest network time by only mapping the points or channels for the I/O modules. Status and output echo information, if available in the input data from a module, is not included.

The software configuration tool selects the factory defaults as default values when a module is added to the configuration.

Factory default for the adapter (out-of-the-box configuration) is no devices in the Compact I/O system. Until the Compact I/O system is configured with the software, no I/O connections can be made. For more information, refer to Configuring Your Compact I/O Series A

DeviceNet Adapter in Chapter 3 or Configuring Your Compact I/O Series B DeviceNet Adapter in Chapter 4.

Configuring Your Compact I/O Series A DeviceNet Adapter 3-7

Using Banks of I/O

Configuration Rules for the Series A Adapter

• The Series A adapter must be the first and left-most module in

the system (the first module of Bank 1).

• The Series a adapter can communicate with up to 30 modules in

a system.

• Each bank of I/O must have its own power supply.

• A bank of I/O can have a maximum of 16 modules with a

maximum of eight on either side of the power supply,

depending upon module loading on the supply.

• A 1769 I/O power supply has limits in the amount of +5V dc and

+24V dc current it can supply to the modules in its I/O bank.

These limits depend on the catalog number (e.g. 1769-PA2) of

the supply. A bank of modules should not exceed the current

limits of the I/O bank power supply. Refer to the Compact 1769

Expansion I/O Power Supplies Installation Instructions,

publication 1769-5.14.

• The maximum amount of current each bank supports in one

direction (either side of the power supply) is: 2A @ 5V dc, 1A @

24V dc.

• If another bank of I/O is required, use a bus communication

expansion cable (e.g. 1769-CRL) to link them together. You can

have a maximum of three banks of I/O connected with up to

two communication expansion cables.

• Each module type has its own distance rating (the number of

modules from the power supply). Each module must be within

this rating for its type.

• The Series A adapter has a distance rating of four, therefore the

adapter must be within four modules of the power supply.

• The Series A adapter supports a total of:

– 180 words of input data from the I/O modules. – 180 words of output data for the I/O modules. – 724 words of configuration data for the I/O modules.

• An end cap/terminator must be on the last I/O bank.

Configuring Your Compact I/O System Online

If your 1769 I/O system physically exists, you’ll save time by configuring the Compact I/O system online. By configuring online, you simply upload the entire I/O layout including end caps, cables, and power supplies. Then, you only need to modify the configuration parameters for each I/O module and re-save (download) the final configuration back to the Series A 1769-ADN adapter.

Online configuration is completed in the same way as the offline configuration with the addition of the following features:

Apply/OK Button

When you choose Apply or OK, the software downloads the configuration of the desired devices to the 1769-ADN if the key check on the system keying configuration has passed.

If the downloaded system keying configuration (the configuration that identifies all the devices present, their location, and keying option) does not match the keys of the actual 1769 devices, the 1769-ADN will reject all downloaded configuration and you’ll see an error message. You’ll then need to return to the appropriate section of the configuration tool and make your changes or change the actual hardware/device on the 1769 bus.

Refer to the Comparison Feature section on page 3-22 for more information on matching system keying configuration and keys of the actual 1769 devices. The 1769-ADN will not accept I/O connections from any scanner until the system keying configuration is successfully downloaded.

Once all configuration is successfully downloaded, RSNetworx has the 1769-ADN save all the configuration in non-volatile memory. This includes the Series A adapter configuration and the configuration of all of the 1769 devices.

Publication 1769-UM001B-EN-P - October 2002

3-22 Configuring Your Compact I/O Series A DeviceNet Adapter

Comparison Feature

The comparison feature regards matching. A match or mismatch is determined based on a comparison of the programmed devices (the devices stored in the adapter’s non-volatile memory) and the actual devices present on the 1769 bus. The electronic keying options (below) are applied on a position-by-position basis.

Each desired device and its location, modified by its electronic key option (if settable), must match the corresponding actual device. If the electronic key option for a device is set to Exact Match, then the desired device’s type (vendor id, product type, and product code), major revision, and minor revision must exactly match its corresponding actual device to consider this entry a match.

If the electronic key option is set to Disable Keying, then the device can be any type and revision and will be considered a match to its corresponding actual device.

IMPORTANT

Disable keying is not recommended because it may allow an improper 1769 system configuration.

If the electronic key option for a device is set to Compatible Module, then the desired device’s type must exactly match and its major/minor revision must be equal to or less than the corresponding actual device’s type. A major/minor revision of 2.3 is considered greater than a major/minor revision of 1.9.

Remember, in order for the system keying configuration to be valid, all of the desired devices (modified by their keying option) must match.

Uploading Configurations

The first time you select a 1769-ADN from RSNetworx when online, the software will upload the configuration saved in the 1769-ADN.

TIP

You may upload the saved configuration from the 1769-ADN at any time when online by clicking the right mouse button.

If there is a mismatch between the saved system keying configuration and the keys of the actual devices on the 1769 bus, you will see the following mismatch screen.

The mismatch screen identifies all of the devices in the saved system keying configuration and all of the actual devices and then highlights the mismatches. You can choose to pull the saved configuration into the configuration software or pull the actual device’s information into the configuration software.

When you choose to pull the saved configuration, the individual I/O module configurations that had been saved by the 1769-ADN are used. When you choose to pull the actual device’s information, the individual I/O module configurations from the actual devices are used.

Downloading Configurations

When you complete a configuration online and choose Apply or OK, assuming the configuration passes the audit, RSNetworx downloads the configuration to the 1769-ADN. The 1769-ADN then performs a key check on the requested devices. Refer to the Comparison Feature on page 3-22.

If there is a mismatch between the desired system keying configuration and the keys of the actual devices on the 1769 bus, you will see the following mismatch screen.

The mismatch screen identifies all of the devices in the desired system keying configuration and all of the actual devices and then highlights the mismatches. You can choose to pull the actual device’s information into the configuration software or to cancel.

When you choose to use the actual device’s information, RSNetworx will replace all of its’ configuration settings, including the individual I/O module configuration, with the configuration of the actual device.

When you choose cancel, you can go back and edit your requested configuration without losing all of your previous configurations.

Using the Clear Memory Function

The Clear Memory feature is activated by choosing Reset Configuration and Upload Actual Devices under the Reset tab. This

will return the 1769-ADN to the ‘No Adapter or I/O Configuration’ state (as if it never was configured for the 1769 modules) and cause the software to pull the configuration from the actual devices.

Configured 1769-ADN Powerup Behavior

IMPORTANT

On powerup, the 1769-ADN, with a previous valid configuration, will compare the saved system keying configuration with the actual devices to determine if all of the keys match the actual devices (as defined in the Comparison Feature section on page 3-22).

If they match, the 1769-ADN will complete the configuration of all I/O modules and then wait for a DeviceNet master/scanner to make a connection. If any of the keys do not match, the 1769-ADN will not permit a DeviceNet master/scanner to make an I/O connection and will wait for a valid configuration.

The 1769-ADN is not configured with the actual device configuration shown at this point. You must choose Apply or OK to download the Series A adapter and I/O configurations for the Compact I/O system to be properly configured.

4. Make sure that the last bank of the node is an end

cap/terminator (1769-ECR or 1769-ECL).

For information on 1769 bus configuration rules, refer to Configuration Rules for Series B Adapters on page 4-6.

5. Choose Apply to be sure that your system passes the electrical

audit.

6. After defining the devices on this 1769-ADN node, refer to the

relevant sections on pages 4-9 to 4-25 to configure each 1769 I/O module.

7. Once all of the I/O modules are configured, choose OK.

8. From the File menu, choose Save.

9. Go on-line.

10. Select the adapter you wish to modify and download your

changes to make them go into affect.

TIP

If your selected adapter is in a scanner’s scanlist, you may have to deactivate it’s entry in the scanlist in order for the download to succeed with no errors. If no input or output sizes were changed, deactivating the adapter’s scanlist entry is usually not necessary.

Using Banks of I/O

Configuration Rules for Series B Adapters

• The Series B adapter must be the first and left-most module in the

system (the first module of Bank 1).

• The Series B adapter can communicate with up to 30 modules in

a system.

• Each bank of I/O must have its own power supply.

• A bank of I/O can have a maximum of 16 modules with a

maximum of eight on either side of the power supply, depending upon module loading on the supply.

• A 1769 I/O power supply has limits in the amount of +5V dc and

+24V dc current it can supply to the modules in its I/O bank. These limits depend on the catalog number (e.g. 1769-PA2) of the supply. A bank of modules should not exceed the current limits of the I/O bank power supply. Refer to the Compact 1769 Expansion I/O Power Supplies Installation Instructions, publication 1769-5.14.

• The maximum amount of current each bank supports in one

direction (either side of the power supply) is: 2A @ 5V dc, 1A @ 24V dc.

• If another bank of I/O is required, use a bus communication

expansion cable (e.g. 1769-CRL) to link them together. You can have a maximum of three banks of I/O connected with up to two communication expansion cables.

• Each module type has its own distance rating (the number of

modules from the power supply). Each module must be within this rating for its type.

• The Series B adapter has a distance rating of five, therefore the

adapter must be within five modules of the power supply.

• The Series B adapter supports reading a maximum of 163-251

words (326-502 bytes) of input data distributed across all the modules, depending on the number of modules present in the system.

Publication 1769-UM001B-EN-P - October 2002

Use the following equation to calculate the maximum number of input words:

Maximum Input Words = 256 - [(Number of Modules +1) x 2 + Number of Output Only Modules + 1]

Where the "Number of Modules" is the total number of modules (input and output) in the system, and the "Number of Output Only Modules" is the number of output modules configured to have 0 words of input data.

The maximum number of input words is distributed across all of the input modules.

Configuring Your Compact I/O Series B DeviceNet Adapter 4-7

• The Series B adapter supports a maximum of 196-254 words

(392-508 bytes) of output data distributed across all of the modules, depending on the number of modules present in the system.

Use the following equation to calculate the maximum number of output words:

Maximum Output Words = 256 - (Number of Output Modules) x 2

Where the "Number of Output Modules" is the number of output modules configured to have 1 or more words of output data.

The maximum number of output words is distributed across all of the output modules.

• The Series B adapter supports a maximum of 254 words (508

bytes) of configuration data to each individual module, for a total capacity of 7,620 words (15,240 bytes). The configuration data is stored within 1 (64K) sector of the external flash part, enabling the maximum for each module to be supported, regardless of the number of modules.

• An end cap/terminator must be on the last I/O bank.
