Ethernet Network Troubleshooting

All Ethernet Network faults will activate the alarm relay. Use the fault messages on the Alarm screen along with this table to diagnose and correct Ethernet network problems. You can also use the Network Status and Node Configuration screens, and the Ethernet Controller Troubleshooting to diagnose problems with the remote nodes.

 

Error Code

Message/Condition

Correction

901

I/O error

Check Ethernet wiring. Remote node could be disconnected from network or turned off

902

Port or socket open error

Programming error. Contact Nordson technical support

903

Serial port already open

Programming error. Contact Nordson technical support

904

TCP/IP connection error

Check Ethernet wiring. Remote node could be disconnected from network or turned off

905

TCP/IP Connection closed by remote peer fault (any remote node fault)

Ethernet network communication with the remote node has been lost. This fault may be a normal response to removing electrical power from the remote node. If the remote node is an in/out positioner or reciprocator and communication is lost while operating in Auto mode, the machine will move to the Park position.

Check the Network Node Status screen. If communication is lost the node icon should turn red. If no nodes are red, check the Network Node Configuration screen to find the device associated with the faulted node IP address.

If multiple node faults are displayed:

  • Check the electrical power supply to all faulted nodes.

  • Check the Ethernet switch in the network interface box for electrical power and proper operation. The switch power LED should be lit and the network connection LEDs should be flashing. Replace the switch if necessary.

  • Check the network cable and connections between the Ethernet switch and the iControl console. Refer to Troubleshooting Ethernet Cables.

  • Check the Ethernet card on the iControl PC for proper operation. The ACT LED indicates network traffic when lit. The LNK LED to the right of the RJ45 connector indicates network status (green: 10 Mbs, amber: 100 Mbs, off: no connection). Replace the card if necessary, using only an identical or Nordson supplied replacement.

If a single node fault is displayed:

  • Check the electrical power to the remote node controller or coupler.

  • Check network cables and connections between the remote node and the Ethernet switch (in the network interface box). Refer to Troubleshooting Ethernet Cables.

Programming error or remote hardware error. Check Fieldbus controller functions. Refer to Ethernet Controller Troubleshooting

925

Illegal Function exception response

Programming error or remote hardware error. Check Fieldbus controller functions. Refer to Ethernet Controller Troubleshooting

926

Illegal Data Address exception response

Programming error or remote hardware error. Check Fieldbus controller functions. Refer to Ethernet Controller Troubleshooting

927

Illegal Data Value exception response

Programming error or remote hardware error. Check Fieldbus controller functions. Refer to Ethernet Controller Troubleshooting

928

Slave Device Failure exception response

Programming error or remote hardware error. Check Fieldbus controller functions. Refer to Ethernet Controller Troubleshooting

3100, 3200

Watchdog Fault
(any remote node controller fault)

Control program in remote node controller is not running, or controller has no program installed

NOTE: This fault may be a normal response to removing electrical power from the remote node

  • Check the remote node controller mode selection switch. The switch should be in the run (up) position

  • Replace the remote node controller. The replacement must be pre-programmed or a program must be downloaded and installed in the field.

  • Contact Nordson Finishing Customer Support for details.
