Event type Description Cause
00100 System Link-up Link-up has occurred when the network cable connected to the
external device was connected.
00110 TCP connection communication start/end Communication using the TCP connection with the external device was
started or ended.
00120 FTP connection start/stop FTP connection was started from the external device or disconnected.
00130 Receive frame error • Receive frame error was detected.
• The Ethernet-equipped module was connected to the CC-Link IE
Controller Network or CC-Link IE Field Network.
00140 Time synchronization failure No response was returned from the time information server (SNTP
server) and time synchronization has failed.
00400 Restart by a program The module was restarted by the program.
00800 Link-down Link-down has occurred when network cable connected to the external
device was disconnected.
00901 Data length error The send/receive data length exceeds the allowable range.
00902 Initial processing error Socket communications or communications using the fixed buffer were
executed before the initial processing was completed.
00903 Specification IP address error Broadcast address was specified to the IP address of the external
device other than Unpassive.
00904 Socket communications transmission failed Message send of the socket communications has failed.
00905 Not opened • The open processing of the external device has not been completed.
• The connection with the external device is closed.
00906 Alive check error The existence of the external device could not be checked within the
response monitoring timer value.
00907 Divided messages receive timeout error • 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.
00908 IP assembly timeout error An IP assembly timeout error has occurred. (The remaining part of the
divided data could not be received and a timeout has occurred.)
00909 TCP specification port number error The port number used in a connection already opened is set. (For TCP/
IP)
0090A UDP specification port number error The port number used in a connection already opened is set. (For
UDP/IP)
00A00 System switching request issued A system switching request occurred.
00C02 Access abnormal response of another station • Abnormal response was returned from another station when
accessing another station.
• Abnormal response was returned to another station when accessed
from another station.
00D00 Fixed buffer response send failed Response send of the communications using the fixed buffer has
failed.
00D01 Pairing open error The open processing of the connection specified for pairing open has
been already completed.
00D02 End code error An abnormal end response was received for communications using the
fixed buffer and random access buffer.
00D03 Response monitoring timeout error • 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.
00D04 Fixed buffer send failed Message send of the fixed buffer has failed.
00D05 Random access communication error The parameter (start address and data word) of the data received by
the random access communication is faulty.
