• Check the error code appended to the end code and correct the
error.
• Increase the CPU monitoring timer value.
• After unlocking the remote password using the MC protocol,
perform communications using a fixed buffer.
• Exclude ports used for communications using a fixed buffer from
the targets of the remote password check.
• Correct the request details.
• Correct the open setting.
• Check and correct the text length or request data length of the Qn
header. Then send data to the Ethernet module again.
• Correct the request details and command.
• Refer to the troubleshooting section of the user's manual
(hardware design, maintenance and inspection) for the CPU
module used, and take corrective action.
• Refer to a manual such as a serial communication module user's
manual, and take corrective action.
• Refer to the CC-Link System Master/Local Module User's Manual,
and take corrective action.
• Correct the IP address. Set the class to A/B/C.
• Correct the subnet mask.
