Status Cause Corrective Action
Off The option module is not powered or is not
properly connected to the drive. • Securely connect and ground the option module to the drive by fully
inserting it into the drive port and tightening its two captive screws to the
recommended torque.
• Apply power to the drive.
Flashing Red The option module is not communicating with the
drive via DPI. • Verify that the option module is properly inserted in the drive port.
• Cycle power to the drive.
Steady Red The drive has refused an I/O connection from the
option module.
Another DPI peripheral is using the same DPI port
as the option module.
Important: Cycle power to the drive after making any of the following
corrections:
• Securely connect and ground the option module to the drive by fully
inserting it into the drive port and tightening its two captive screws to the
recommended torque.
• Verify that the drive supports the Comm Driver.

parameter settings may have been corrupted. Reset defaults and
reconfigure the option module.
• If resetting defaults does not correct the problem, update the option
module with the latest firmware revision.
Steady Red The option module has failed the hardware test. • Cycle power to the drive.
• Replace the option module.
Flashing Green The option module is operating normally, 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 option module.
• Configure the option module for the program in the controller.
