NET A Status Indicator
This red/green bicolor LED indicates the status of the network connection
as shown in the table below.
NET B Status Indicator
This green LED indicates the status of the adapter transmitting on the
network as shown in the table below.
Status Cause Corrective Actions
Off The adapter is not powered, the adapter is
not properly connected to the network, the
adapter needs an IP address, or BOOTP is
enabled.
• Securely connect the adapter to the drive using the Internal Interface
(ribbon) cable and to the network using an Ethernet cable.
• Correctly connect the Ethernet cable to the Ethernet connector.
• Set a unique IP address and disable BOOTP using a BOOTP server,
or set a unique IP address by using adapter parameters.
• Apply power to the drive (or adapter if mounted in a DPI External
Comms Kit).
Steady Red The adapter failed the duplicate IP address
detection test.
Configure the adapter to use a unique IP address and cycle power.
Flashing Red An EtherNet/IP connection has timed out. • Place the scanner in RUN mode, or apply power to the peer device
that will send I/O.
• Check the IGMP Snooping/Ethernet Switches for correct operation.
• Check the amount of traffic on the network.
Flashing Red/
Green
The adapter is performing a self-test. No action required.
Flashing Green The adapter is properly connected, has an IP
address, and is connected to an EtherNet/IP
network but does not have an I/O connection.
• Place the controller in RUN mode, or apply power to the peer device
that will send I/O.
• Program the controller or peer device to recognize and transmit I/O
or make a messaging connection to the adapter.
• Configure the adapter for the program in the controller or the I/O
from the peer device.
Steady Green The adapter is properly connected and
communicating on the network to a controller.
No action required.
Status Cause Corrective Actions
Off The adapter is not powered or is not
transmitting on the network.
If NET A indicator is off:
• Securely connect the adapter to the drive using the Internal Interface
(ribbon) cable and to the network using an Ethernet cable.
• Correctly connect the Ethernet cable to the Ethernet connector.
• Set a unique IP address using a BOOTP server or by disabling
BOOTP and using adapter parameters.
If NET A indicator is steady red:
• Configure the adapter to use a unique IP address and cycle power.
If NET A indicator is flashing red/green or red:
• Check the IP address in the adapter and scanner, and verify that the
controller can communicate with the adapter.
• Ping the adapter.
Normal condition if the adapter is idle.
Flashing Green The adapter is properly connected, BOOTP is
enabled, and the adapter is transmitting data
packets on the network.
No action required.
