Error details and cause
• Data was not sent correctly with
UDP/IP.
• Data was not sent correctly with
TCP/IP.
• Unsent data found, but could not
be sent.
• The same IP address has been
set as the system A IP address,
system B IP address, and/or
control system IP address
• Network addresses of the system
A IP address, system B IP
address, and control system IP
address are different.

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.
