C0B2H There is no sufficient space in the receive buffer or the
send buffer of the relay station or external station for the
MELSOFT connection, link dedicated instructions, or
SLMP. (Send receive buffer full error)
• Increase the request interval (execution interval) and
execute the operation.
• Do not access through one station using the
MELSOFT connection, link dedicated instruction, or
SLMP.
• Wait for a response to the previous request before
sending the next request.
• Correct the set value for "Timer Settings for Data
Communication" under "Application Settings" of the
Ethernet-equipped module.
C0B3H A request that cannot be processed was issued from the
CPU module.
• Correct the request details.
• Correct the network number or request destination
station number.
C0B6H The channel specified by the dedicated instruction is out
of the range.
Correct the channel to a value within the allowable range
of each dedicated instruction.
C0BAH Since the close processing is in execution using the
CONCLOSE/CLOSE instruction, a send request cannot
be accepted.
Do no perform the send processing during the close
processing.
C0C4H The UINI instruction has been executed during
communications.
Execute the UINI instruction after closing all connections.
C0D0H The specified data length of the link dedicated instruction
is incorrect.
Correct the data length.
C0D1H The number of resends of the link dedicated instruction is
incorrect.
Correct the number of resends.
C0D3H The number of relay stations to communicate with other
networks exceeds the allowable range.
• Check if the specification (network number/station
number) for the communication destination is correct.
• Check that number of relay stations accessing to the
communication destination is 7 or less.
• Correct the settings in the Network station number <->
IP information for the stations between the own station
and the communication destination.
C0D4H The number of relay stations to communicate with other
networks exceeds the allowable range.
• Check if the specification (network number/station
number) for the communication destination is correct.
• Check that number of relay stations accessing to the
communication destination is 7 or less.
• Correct the settings in the Network station number <->
IP information for the stations between the own station
and the communication destination.
C0D5H The number of retries of the link dedicated instruction is
incorrect.
Correct the number of retries.
C0D6H The network number or station number of the link
dedicated instruction is incorrect.
Check if the specification (network number/station
number) for the communication destination is correct.
C0D7H Data were sent without the initial processing completed. After normal completion of the initial processing, perform
the communications with the external device.
C0D8H The number of specified blocks exceeded the range. Correct the number of blocks.
C0D9H The specified subcommand of the SLMP message is
incorrect.
Correct the subcommand.
C0DAH A response to the PING test could not be received within
the time of the communication time check.
• Correct the IP address and host name of the target
module where the PING test is executed.
• Check that the initial processing of the Ethernet-
equipped module where the PING test is executed is
completed successfully.
C0DBH The IP address and host name of the target module
where the PING test is execute are incorrect.
Correct the IP address and host name of the target
module where the PING test is executed.
C0DEH Data could not be received within the specified arrival
monitoring time.
• Correct the specified arrival monitoring time.
• Correct the channel of the link dedicated instruction.
• Check if the sending station and relay station are
operating normally.
C101H A response could not be received from the DNS server. • Check the address of the DNS server.
•
Check that the data communications with the DNS
server is possible by using the Ping command.
• Check that the own station IP address and the DNS
server IP address are in the same class. (If not, check
the router setting.)
