Remote I/O (Ethernet) Network Troubleshooting
All Remote I/O 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 Remote Node Troubleshooting tables on
page 4-33 to diagnose problems with the remote nodes.
Table 4-6 Ethernet Network Troubleshooting
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 Testing Ethernet Cables
in this section.
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 RJ-45 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
Testing Ethernet Cables in this section.
906 Socket library error Programming error. Contact Nordson technical support.
907 TCP port already bound Programming error. Contact Nordson technical support.
