Status Cause Corrective Action
Off The adapter is not powered or is not properly
connected to the drive.
• Securely connect the adapter to the drive using the Internal Interface
(ribbon) cable.
• Apply power to the drive (or adapter if mounted in a DPI External
Comms Kit).
Flashing Red The adapter is not receiving a ping message
from the drive.
• Verify that cables are securely connected and not damaged. Replace
cables if necessary.
• Cycle power to the drive (or adapter if mounted in a DPI External
Comms Kit).
Steady Red The drive has refused an I/O connection from the
adapter.
Another DPI peripheral is using the same DPI
port as the adapter.
Important: Cycle power to the drive (or adapter if mounted in a DPI
External Comms Kit) after making any of the following corrections:
• Verify that all DPI cables on the drive are securely connected and not
damaged. Replace cables if necessary.
• Verify that the DPI drive supports Datalinks.
• Configure the adapter to use a Datalink that is not already being used
by another peripheral.
Steady Orange The adapter is connected to a product that does
not support Allen-Bradley DPI communications.
Connect the adapter to a product that supports Allen-Bradley DPI
communications (for example, a PowerFlex 7-Class drive).

Comms Kit).
Flashing Red The adapter has failed the firmware test.
The adapter firmware is being updated.
The node address switch setting is not valid.
• Clear faults in the adapter.

settings may have been corrupted. Reset defaults and reconfigure the
adapter.
• If resetting defaults does not correct the problem, update the adapter
with the latest firmware revision.
• Verify that the node address switch setting is valid (0…63).
Steady Red The adapter has failed the hardware test. • Cycle power to the drive (or adapter if mounted in a DPI External
Comms Kit).
• Replace the adapter.
Flashing Green The adapter is operational, but is not transferring
I/O data to a controller.
• Place the scanner in RUN mode.
• Program the controller to recognize and transmit I/O to the adapter.
• Configure the adapter for the program in the controller.
• Normal behavior if no DPI I/O is enabled.
