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.
