3.5 List of Error Codes
Action
• Check and correct the response waiting time.
• Change the system configuration so that the number of
relay stations may be seven or less.
• For the RECV instruction, execute again after
correcting the channels used by own station in the
control data.
• For the RECV instruction, check that 'RECV execution
request' (Un\G5301 b0 to b7) are on.
• Check the operation of the external device.
• Check if the external device supports the executed
function.
• Check that all of the specified command,
subcommand, and request destination module I/O
number of the SLMP message is correct.
• Correct the specified value for the clear function set by
the ERRCLEAR instruction.
• Correct the specified value for the information to be
read set by the ERRRD instruction.
• Connect it directly to the CPU module (built-in Ethernet
port part) or use a USB cable to use the Ethernet
diagnostics, CC-Link IE Field Network diagnostics, or
CC-Link IE Controller Network diagnostics.
Correct the specified the target station or clear target.
Correct the setting value of the connection number.
Correct the specified network number.
Correct the specified station number.
Correct the specified device number.
Correct the specified device name.
Correct the number of resends.
Correct the specified data length.
Correct the specified port number
• Do not perform the open processing to a connection
already opened.
• When communications with the external device cannot
be performed, perform the close processing before the
open processing.
After completion of the open processing, perform the
communication.
Execute again after the CONOPEN/CONCLOSE/OPEN/
CLOSE instruction is completed.
• Change the channel number.
• Execute again after the send or receive instruction is
completed.

allowable range.
• Correct the execution condition of the RECV
instruction for the channel that had received data.
• Correct the specified channel of the RECV instruction.
Correct the specified connection.
Execute the dedicated instruction after the initial
processing is completed.
Correct the specified target station CPU type.
• Execute the link dedicated instruction again after
correcting the network number.
• When specifying another network station, check if the
