code
1166H TCP/IP send • Data was not sent correctly with TCP/
failed IP.
1167H Unsend data • Unsent data found, but could not be
send error sent.
1180H Redundant IP • The same IP address has been set as
address error 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.
1200H Module • A moderate error has been notified
moderate error from the intelligent function module
connected.
1210H • An inter-module synchronous signal
error has been notified from the
intelligent function module connected.
1220H Another CPU • A moderate error has been notified
module from another CPU module.

Stop/ Action
continue
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.
