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.
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.
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.
