DeviceNet
Network Status
(NS)
None —
The EtherNet/IP
Communications Auxiliary is
not receiving power.
Check the DeviceNet cable
connections and verify that
24V DC exists between the red
and black terminals.
Green, Red,
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.
Duplicate DeviceNet module
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.
Module Status
None —
The EtherNet/IP
Communications Auxiliary is
not receiving power.

and black terminals.
Green, Red,
Not Illuminated
Flashing
(once)
Normal This is a normal power-up
sequence.
Green Flashing
The EtherNet/IP
Communications Auxiliary is
proper;y scanning DeviceNet
slave devices, but it is not
being scanned by the
EtherNet/IP master.
Check the Ethernet scan list
for the correct scanner
configuration.
Green Solid
Normal operating state, the
EtherNet/IP Communications
Auxiliary is scanning
DeviceNet slave devices, and
is allocated to its master.
No action is required.
Red Flashing
One or more DeviceNet or
EtherNet/IP connections timed
out.
Reset the EtherNet/IP
Communications Auxiliary.
The EtherNet/IP
Communications Auxiliary is
not configured to scan any
DeviceNet slave devices.
Check the DeviceNet scan list
for correct scanner
configuration.
Red Solid
Diagnostics test failed on
power-up/reset.
Cycle power to the device. If
the fault still exists, replace
the device.
