Error
Error description
code
The device memory cannot be extended for the target
C070
H
station.
The number of device points for data read/write set for
C071
H
modules other than a Q/QnACPU is too large.
Incorrect request (For example, a request for data
C072
H
read/write in bit units has been issued to a word device.)
The Ethernet module cannot issue this request to the
target programmable controller CPU. (For example, the
C073
H
number of double word access points cannot be
specified for modules other than a Q/QnACPU.)
This request cannot be executed to the target
C074
H
programmable controller CPU.
The destination IP address could not be obtained during
CC-Link IE Controller Network, CC-Link IE Field
C080
Network, MELSECNET/H, MELSECNET/10 relay
H
communications or communications using data link
instructions.
The termination process for the Ethernet module is in
C081
process, and whether communications using data link
H
instructions have reached cannot be checked.
The communication process was abnormally ended in
the following communications.
• Communications with a programming tool (UDP/IP)
C082
H
• CC-Link IE Controller Network, CC-Link IE Field
Network, MELSECNET/H, MELSECNET/10 relay
communications
The communication process was abnormally ended in
C083
H
communications using data link instructions.
CHAPTER 16 TROUBLESHOOTING
Action
• Read/write data without the device memory set for extension.
• Device memory can be extended only in an Ethernet
module-connected station and a Q/QnACPU via CC-Link IE
Controller Network, MELSECNET/H, or MELSECNET/10.
• Correct the number of device points for data read/write and send
the data to the Ethernet module again.
• Check whether the data can be requested to the target
programmable controller CPU.
• Correct the request details and send it to the Ethernet module
again. (For example, change the subcommand.)
• Correct the request details.
• Correct the network number or PC number.
• Correct the read/write request details.
• Set the Station No. <-> IP information in the Ethernet module.
• Change the conversion method for the CC-Link IE Controller
Network, CC-Link IE Field Network, MELSECNET/H, and
MELSECNET/10 relay communication parameters.
• Finish all the communications to perform the termination process
of the Ethernet module.
• Check if the relay station/connected station is operating normally.
(If the communication is alive, no action for this error is required.)
• Check if there is an error with the cable connection between the
own station and the connected station.
• If the line is heavily loaded, reduce the load.
• Increase the number of resends for the data link instructions.
• Increase the time reserved for the communication process.
• For a Basic model QCPU, High Performance model QCPU,
Process CPU, or Redundant CPU, use Time reserved for
communication process (SD315).
• For a Universal model QCPU, configure the service processing
setting in "PLC System" under "PLC Parameter".
• Check if the relay station/connected station is operating normally.
(If the communication is alive, no action for this error is required.)
• Check if there is an error with the cable connection between the
own station and the connected station.
• If the line is heavily loaded, reduce the load.
• Increase the number of resends for the data link instructions.
• Increase the time reserved for the communication process.
• For a Basic model QCPU, High Performance model QCPU,
Process CPU, or Redundant CPU, use Time reserved for
communication process (SD315).
• For a Universal model QCPU, configure the service processing
setting in "PLC System" under "PLC Parameter".
