1166H TCP/IP send
failed
• Data was not sent correctly with TCP/
IP.
Continue • Check the settings for connection
with the external device.
• 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.
• Execute a PING test. If the test
completes with an error, take an
action to correct the error.
 Always
1167H Unsend data
send error
• Unsent data found, but could not be
sent.
Continue • Check the settings for connection
with the external device.
• 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.
