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.
