code
C032H The external device does not send an
ACK response in the TCP/IP
communications.
C035H The alive status of an external device
could not be checked.
C037H • The receive buffer or send buffer is not
sufficient.
• The window size of the external device
is not sufficient.
C038H Data was not sent correctly with UDP/IP.
C039H Data was not sent correctly with TCP/IP.
C040H • 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.
C050H ASCII code data that cannot be converted
to binary code was received.
C051H • The number of read/write points from/to
the device of SLMP message is out of
the allowable range in the CPU module
(in units of words).
• The number of write points for the long
counter of SLMP message is not in two-
word units.
C052H The number of read/write points from/to
the device of SLMP message is out of the
allowable range in the CPU module (in
units of bits).

4.5 List of Error Codes
Action
• Since there may be congestion of packets on the line, send data after a
certain period of time.
• Check if the Ethernet cable is connected properly.
• Check the operation of the external device.
• Correct the timer setting for data communication of the CC-Link IE TSN-
equipped module.
• Check if the Ethernet cable is connected properly.
<When using PLCopen Motion control FB mode>
• Check the operation of the external device or switching hub.
• When the value of the 'Receive buffer status storage area' (Un\G6291486)
is 0001H, reduce the frequency of data received from the external device.
<When using Simple Motion mode>
• Check the operation of the external device or switching hub.
• When the value of the 'Receive buffer status storage area' (Un\7891486)
is 0001H, reduce the frequency of data received from the external device.
• Check the connection settings and operations (whether an error has
occurred or it is being reset) of the external devices (including the
switching hub), and connection failure (whether the cable is
disconnected).
• Since there may be congestion of packets on the line, send data after a
certain period of time.
• Execute the PING test and communication status test, and if the test was
completed with an error, take the corrective action.
• Correct the network No. and station No./IP address of the target station of
the dedicated instruction.
• Check the connection settings and operations (whether an error has
occurred or it is being reset) of the external devices (including the
switching hub), and connection failure (whether the cable is
disconnected).
• Since there may be congestion of packets on the line, send data after a
certain period of time.
• Execute the PING test and communication status test, and if the test was
completed with an error, take the corrective action.
• Correct the data length of the communication data.
• Since there may be congestion of packets on the line, send the data again
from the external device after a random amount of time has passed.
Check if the ASCII code data that cannot be converted into binary code data
was sent from the external device.
Correct the number of read/write points and send the SLMP message to the
CC-Link IE TSN-equipped module again.
Correct the number of read/write points and send the SLMP message to the
CC-Link IE TSN-equipped module again.
Correct the number of read/write points and send the SLMP message to the
CC-Link IE TSN-equipped module again.
Correct the number of read/write points and send the SLMP message to the
CC-Link IE TSN-equipped module again.
Correct the read/write size and send the SLMP message to the CC-Link IE
TSN-equipped module again.
