Troubleshooting the 1734-ADN(X) Adapter 6-3
Network Status Off Device is not online
- Device is autobauding
- Device has not completed
dup_MAC_id test
- Device not powered
Check adapter status
indicator to determine if
more time is needed to
complete the dup_MAC_id
test or if the adapter needs
to be powered
Flashing Green Device is on-line but has no
connections in the
established state
None
Green Device on-line and has
connections in the
established state
None
Flashing Red One or more I/O
connections in timed-out
state
Determine the cause of the
time-out. The EPR may
need to be increased
Red Critical link failure - failed
communication device.
Device detected error that
prevents it communicating
on the network.
Make sure the device is
using the correct MAC ID
and baudrate
Subnet and
PointBus Status
Off Device is not on-line
- Device has not completed

None
Flashing Red No scanlist is available.
I/O module is missing.
Make sure all I/O modules
are connected and using
the correct MAC IDs.
Check “Cycling Node
Status” parameter in
RSNetWorx for DeviceNet.
Red Critical link failure - failed
communication device.
Device detected error that
prevents it communicating
on the network.
Make sure an I/O module is
not using a MAC ID =0.
Make sure all backplane
modules are
communicating at the
proper baudrate.
