Not Illuminated
Flashing
(once)
Normal This is a normal power-up
sequence.
Green Flashing
The EtherNet/IP
Communications Auxiliary is
not configured to scan any
DeviceNet slave devices.
Check the DeviceNet scan list
for the correct scanner
configuration.
Green Solid
Normal operating state and
the EtherNet/IP
Communications Auxiliary is
scanning DeviceNet slave
devices.
No action is required.
Red Flashing
One or more DeviceNet
connections timed out.
Reset the EtherNet/IP
Communications Auxiliary.
Red Solid
Diagnostics test failed on
power-up/reset. An internal
fault exists.
Cycle power to the unit. If the
fault still exists, replace the
unit.

address exists. Two modules
cannot have the same address.
Change the MAC address to a
valid setting and reset the
device.
A fatal communication error
occurred.
Check DeviceNet media for
proper installation.
