Chapter 6 Place, Configure, and Monitor I/O
Place Local I/O Modules
Use the 1769-CRR1/-CRR3 or 1769-CRL1/-CRL3 expansion cable to connect
banks of I/O modules.
Each I/O module also has a power supply distance rating, the number of modules
from the power supply. The distance rating is printed on each module’s label.
Each module must be located within its distance rating.

The CompactLogix controller also supports distributed (remote) I/O via
these networks:
• EtherNet/IP
• ControlNet
• DeviceNet

ATTENTION: The CompactLogix system does not support Removal and
Insertion Under Power (RIUP). While the CompactLogix system is under power:
• any break in the connection between the power supply and the controller (for
example, removing the power supply, controller, or an I/O module) may subject
the logic circuitry to transient conditions above the normal design thresholds
and may result in damage to system components or unexpected behavior.
• removing an end cap or an I/O module faults the controller and may also result
in damage to system components.
