DeviceNet Status indicator
Subnet Status or PointBus Status indicator
flashing red Recoverable fault Make sure the adapter does not need a
FLASH update
solid red Unrecoverable fault may require device
replacement
Replace the adapter
flashing red/green Device is in self-test Wait for self-test to finish
State Description Recommended Action
State Description Recommended Action
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
solid 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
solid 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
baud rate
State Description Recommended Action
off Device is not on-line
• Device has not completed Dup_MAC_ID test.
• Device not powered - check module status
indicator
Check adapter status indicator to determine if more time is
needed to complete the dup_MAC_id test or if the adapter

flashing green Device is online but has no connections in the established
state
None
solid green Device on-line and has connections in the established
state.
None
flashing red No scan list 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

solid 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 baud rate.
