Cause
Link-up has occurred when the network cable connected to the
external device was connected.
Communication using the TCP connection with the external device was
started or ended.
FTP connection was started from the external device or disconnected.
• Receive frame error was detected.
• The Ethernet-equipped module was connected to the CC-Link IE
Controller Network or CC-Link IE Field Network.
No response was returned from the time information server (SNTP
server) and time synchronization has failed.
The module was restarted by the program.
Link-down has occurred when network cable connected to the external
device was disconnected.
The send/receive data length exceeds the allowable range.
Socket communications or communications using the fixed buffer were
executed before the initial processing was completed.
Broadcast address was specified to the IP address of the external
device other than Unpassive.
Message send of the socket communications has failed.
• The open processing of the external device has not been completed.
• The connection with the external device is closed.
The existence of the external device could not be checked within the
response monitoring timer value.
• Not all the data could be received within the response monitoring
timer value.
• Sufficient data for the data length could not be received.
• The remaining part of the message divided at the TCP/IP level could
not be received within the response monitoring timer value.
An IP assembly timeout error has occurred. (The remaining part of the
divided data could not be received and a timeout has occurred.)
The port number used in a connection already opened is set. (For TCP/
IP)
The port number used in a connection already opened is set. (For
UDP/IP)
A system switching request occurred.
• Abnormal response was returned from another station when
accessing another station.
• Abnormal response was returned to another station when accessed
from another station.
Response send of the communications using the fixed buffer has
failed.
The open processing of the connection specified for pairing open has
been already completed.
An abnormal end response was received for communications using the
fixed buffer and random access buffer.
• A response could not be received within the response monitoring
timer value.
• The connection with the external device was closed while waiting for
a response.
Message send of the fixed buffer has failed.
The parameter (start address and data word) of the data received by
the random access communication is faulty.
