10 Compact I/O 1769-ADN DeviceNet Adapter

Rockwell Automation Publication 1769-IN001C-EN-P - February 2013

System Assembly

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

• For mounting instructions, see Panel Mounting on page 11, or DIN Rail Mounting on

page 12.

• To work with a system that is already mounted, see Replacing the 1769-ADN within a

System on page 13.

The following procedure shows you how to assemble the Compact I/O™ system.

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.

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.

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.

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

9. See DeviceNet Wiring

on page 16.

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.

IMPORTANT

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

communication bus.
