NET A Status Indicator—Adapter Mode
This red/green bicolor LED indicates the status for the network connection as
shown in the table below.
NET B Status Indicator—Adapter Mode
This green LED indicates the status of the option module transmitting on the
network as shown in the table below.
Status Cause Corrective Actions
Off The option module is not powered.
The option module is not properly connected to the network.
The option module has not acquired its network configuration (IP
address, subnet mask, gateway address) from the BOOTP/DHCP
server.
• Securely connect and ground the option module to the drive by fully
inserting it into the drive port and tightening its two captive screws to the
recommended torque.
• Correctly connect the Ethernet cable to the Ethernet connector.
• Set a unique IP address with the option module rotary switches, option
module parameters, or a BOOTP or DHCP server.
• Apply power to the drive.
Flashing Red The I/O connection has timed out. • Place the controller 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.
Steady Red A duplicate IP address fault has been detected.
The DHCP lease has expired.
Configure the option module to use a unique IP address and cycle power.
Flashing Green The option module is operating normally, but does not have any
CIP connections (I/O or explicit). • 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 message connection to the option module.
• Configure the option module for the program in the controller or the I/O
from the peer device.
Steady Green The option module is operating normally and has at least one CIP
connection (I/O or explicit). No action required.
Status Cause Corrective Actions
Off The option module is not transmitting on the network. If NET A indicator is off:
• Securely connect and ground the option module to the drive by fully
inserting it into the drive port and tightening its two captive screws to the
recommended torque, and connect the option module to the network using
an Ethernet cable.
• Correctly connect the Ethernet cable to the Ethernet connector.
• Set a unique IP address with the option module rotary switches, option
module parameters, or a BOOTP or DHCP server.
If NET A indicator is steady red:
• Configure the option module 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 option module and scanner, and verify that the
controller can communicate with the option module.
• Ping the option module.
• Normal condition if the option module is idle.
Flashing Green The option module is transmitting on the network. No action required.
