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.
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.
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 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).
Flashing Green The adapter is establishing an I/O
connection to the drive or [DPI I/O Cfg]
is configured for all I/O disabled.
•
No action required. This indicator will turn steady
green or steady red.

•
Apply power to the drive.
Flashing Red The adapter has failed the firmware
test or the Node Address switch setting
is invalid.
Bad CRC of adapter parameters or the

If resetting defaults does not correct the problem,
flash the adapter with the latest firmware release.
Steady Red The adapter has failed the power-on
diagnostics test (hardware failure).
•

•
Replace the adapter.
Flashing Green The adapter is operational, but is not
transferring I/O data. Normal operation,

pre-operational state.
•
Place the PLC 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.
Steady Green The adapter is operational and
transferring I/O data. No action required.
