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 21) and to circuits not exceeding Over Voltage Category II 2 (IEC 60664-1).3

Prevent Electrostatic Discharge

Remove Power

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.

$77(17,21 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.

$77(17,21 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.

Compact? I/O 1769-ADN DeviceNet Adapter5 System Configurations

Configuration Rules

?The adapter must be the first and left-most module in the system (the first module of Bank 1).

?The adapter can communicate with up to 30 modules in a system.?An end cap/terminator must be on the last I/O bank.

?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 the system 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 due to module requirements or I/O loading, you can use a cable to link them together. You can have a maximum of three banks of I/O connected with up to two

communication 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 adapter has a distance rating of four, therefore the adapter must be within four modules of the power supply.

?The adapter supports a total of 180 words of input data from the I/O modules.

?The adapter supports a total of 180 words of output data for the I/O modules.

?The adapter supports a total of 724 words of configuration for the I/O modules.

System Assembly

The adapter can be attached to adjacent 1769 modules before or after mounting. For

mounting instructions, see “Panel Mounting” on page 8, or “DIN Rail Mounting” on page 9. To work with a system that is already mounted, see “Replacing the 1769-ADN within a System” on page 10. The Check that the bus lever of the module to the right of the 1769-ADN is in the unlocked (fully right) position.

Use the upper and lower tongue-and-groove slots (D ) to secure the modules together.

Move the module back along the tongue-and-groove slots until the bus connectors line up with each other.

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

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 (F ) until it clicks. Make sure it is locked firmly into place.

Attach an end cap terminator () to the last I/O module in the system by using the tongue-and-groove slots as before. Lock the end cap bus terminator (H ).

Refer to the “DeviceNet Wiring” section on page 11.

$77(17,21 When attaching a 1769-ADN adapter, it is very important that the bus connectors are securely locked together to create a proper electrical connection.

,PSRUWDQW A 1769-ECR or 1769-ECL right or left end cap must be used to

terminate the end of the serial communication bus.

Mounting the Adapter and I/O Modules

Minimum Spacing

Maintain spacing from enclosure walls, wireways, adjacent equipment, etc. Allow

Panel Mounting

Mount the adapter or module to a panel using two screws per adapter or module. Use M4 or #8 panhead screws. Mounting screws are required on every module.

Panel Mounting Using the Dimensional Template

$77(17,21 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.

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 8.

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

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

Using the assembled modules as a template, carefully mark the center of all module-mounting holes on the panel.

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

Drill and tap the mounting holes for the recommended M4 or #8screw. Place the modules back on the panel and check for proper hole alignment.

Attach the modules to the panel using the mounting screws.

127( 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.

Repeat steps 1 through 6 for any remaining modules.

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.

1769-IN001A-US-P - April 2000

Replacing the 1769-ADN within a System

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

Remove power. See important note on page 4.

Remove the DeviceNet cable from the module by removing the connector.

Remove the upper and lower mounting screws from the adapter (or open the DIN latches using a flat-blade or phillips-style screwdriver). On the right-side adjacent module, move its bus lever to the right (unlock) to disconnect it from the adapter being removed. 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).

1RWH 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.

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

Connect the adapter and modules together by locking (fully left) the bus levers on the right-side adjacent module.

Replace the mounting screws (or snap the adapter onto the DIN rail). Replace the DeviceNet cable on the module by 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 DIN rail (if used), are not required unless you cannot ground the mounting surface. Refer to Industrial Automation

Compact? I/O 1769-ADN DeviceNet Adapter 11

1769-IN001A-US-P - April 2000

Wiring and Grounding Guidelines , publication 1770-4.1, for additional information.

DeviceNet Wiring

Connect the DeviceNet cable to the removable connector as shown.

Insert the removable female connector into the mating male connector on the DeviceNet adapter module.

Screw the removable connector to the adapter case with the upper and lower mounting screws. Screw torque is 5-6 in-lbs.127( DeviceNet cable colors are shown on the wiring label on the front of the adapter.

,PSRUWDQW If the 1769-ADN is the last device connected to the DeviceNet

network trunkline, be sure to add the termination resistor (Allen-Bradley part number 1485A-C2 or a 120? 5% or > ?W resistor) across the Blue (CAN Low) and White (CAN High) wires.

Setting the Network Address Switches

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

Valid network 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 network address.The software programmed value is set via RSNetworx TM for DeviceNet TM and stored in non-volatile memory on the 1769-ADN. The initial, 127( The baud rate for the adapter is set by way of the module’s automatic “auto baud” function at power-up.

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

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 the Compact? I/O 1769-ADN DeviceNet Adapter User Manual , publication 1769-UM001A-US-P.
