ID not completed 1. Verify that the network supply is connected and
that power is reaching the adapter through the
connector.
2. Make sure one or more nodes are communicating
on the network.
3. Make sure at least one other node on the network
is operational at the same time and data rate as the
adapter.

connected Passed duplicate
ID/No connection
established No action needed. The LED is flashing to signify that
there are no open communication connections
between the adapter and any other device. Any
connection (I/O or explicit message) made to the
adapter over DeviceNet will cause the LED to stop
flashing and remain steady on for the duration of
any open connection.

LED is flashing red Online/Time-out I/O connection timed
out 1. Bring controller back onto the network.
2. Reduce traffic or errors on the network so that
messages can get through within the necessary
time frame.
LED is steady red Network failure Failed Duplicate ID
or Bus-off 1. Ensure that all nodes have unique addresses.
2. If all node addresses are unique, examine
network for correct media installation.
