This page will help you troubleshoot any blink codes you may get from the 20-COMM-E module. The EtherNet/IP adapter has four status indicators. They can be viewed on the adapter or through the drive cover. Get familiar with the location of the status indicators:

  #  
 Status Indicator Description
1
 PORT DPI Connection Status
2
 MOD Adapter Status
3
 Net A EtherNet/IP Connection Status
4
 Net B EtherNet/IP Transmit Status

PORT Status Indicator
Status
Cause
Corrective Action
Off The adapter is not powered or is not connected properly to the drive.
  • Securely connect the adapter to the drive using the Internal Interface cable.
  • Apply power to the drive.
Flashing Red The adapter is not receiving a ping message from the drive.
  • Verify that cables are securely connected.
  • Cycle power to the drive.
Solid Red

The drive has refused an I/O connection from the adapter.

Another DPI peripheral is using the same DPI port as the adapter.

Important: Cycle power to the drive after making any of the following corrections:

  • Verify that all DPI cables are securely connected and not damaged. Replace cables if necessary.
  • Verify that the DPI Host supports Datalinks.
  • Configure the adapter to use a Datalink that is not already being used by another peripheral.
Orange The adapter is connected to a product that does not support Allen-Bradley DPI communications. Connect the adapter to a product that supports Allen-Bradley DPI communications (for example, PowerFlex drives).
Flashing Green The adapter is establishing an I/O connection to the drive. No action. Normal behavior if no DPI I/O is enabled.
Solid Green The adapter is properly connected and is communicating with the drive. No action.

MOD Status Indicator
Status
Cause
Corrective Action
Off The adapter is not powered.
  • Securely connect the adapter to the drive using the Internal Interface cable.
  • Apply power to the drive.
Flashing Red

The adapter has failed the firmware test.

The adapter is being flash upgraded.
  • Clear faults in the adapter.
  • Cycle power to the drive.
  • If cycling power does not correct the problem, the parameter settings may have been corrupted. Reset defaults and reconfigure the module.
  • If resetting defaults does not correct the problem, flash the adapter with the latest firmware release.
Solid Red The adapter has failed the hardware test.
  • Cycle power to the drive.
  • Replace the adapter.
Flashing Green The adapter is operational, but is not transferring I/O data.
  • Place the scanner in RUN mode.
  • Program the controller to recognize and
    transmit I/O to the adapter.
  • Configure the adapter for the program in the
    controller.
  • Normal behavior if no DPI I/O is enabled.
Solid Green The adapter is operational and transferring I/O data. No action.

Net A Status Indicator
Status
Cause
Corrective Action
Off The adapter and/or network is not powered, the adapter is not
connected properly to the network, or the adapter needs an IP address.
  • Securely connect the adapter to the drive using the Internal Interface 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 parameters.
  • Apply power to the drive and network.
Solid Red The adapter failed duplicated 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 amount of traffic on the network.
Flashing Red / Green The adapter is performing a self-test. No action.
Flashing Green The adapter is properly connected but is not communicating with any devices on the network.
  • Place the controller in RUN mode, or apply power to the peer device that will send I/O.
  • Program a 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.
Solid Green The adapter is properly connected and communicating on the network. No action required.

NET B Status Indicator
Status
Cause
Corrective Action
Off The adapter is not powered or is not transmitting on the EtherNet/IP network.

Normal condition if the adapter is idle.

If Net A is off:

  • Securely connect the adapter to the drive using the Internal Interface cable and to the network using a 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 parameters.

If Net A is solid red:

  • Configure the adapter to use a unique IP address and cycle power.

If Net A is flashing red/green or red:

  • Check the IP address in the adapter and scanner.
  • Ping the adapter.
Flashing Green The adapter is transmitting on the EtherNet/IP network. No action.
