36.4 List of Error Codes
Error details and cause
• The response send failed during
socket communications.
• A TCP ULP timeout error has
occurred in the TCP/IP
communication. (The external device
does not send an ACK response.)
• The IP address is not set correctly.
• The specified connection was already
closed in TCP/IP communications.
• Open processing is not performed.
• The specified connection was already
closed in UDP/IP communications.
• Open processing is not performed.
• Data was not sent correctly with UDP/

Stop/
Action
continue
Continue
• Check the operation of the
external device or switching hub.
• Since there may be congestion of
packets on the line, send data
after a certain period of time.
• Check if the Ethernet
communication load is high
because of the Ethernet functions
being executed. Use the Ethernet
functions so that the
communication load is reduced.
• Check if the connection cable is
disconnected.
• Check that there is no connection
failure with the switching hub.
Continue
• Check the operation of the
external device.
• Check and correct the TCP ULP
timeout value.
• Since there may be congestion of
packets on the line, send data
after a certain period of time.
• Check if the Ethernet
communication load is high
because of the Ethernet functions
being executed. Use the Ethernet
functions so that the
