USING
Table7.6 shows the error codes, error descriptions, and corrective actions that will be
sent from the CPU module to an external device when an error occurs during
communication using the MC protocol.

Description
BUILT-IN ETHERNET
Corrective action
Refer to the QCPU User's Manual (Hardware Design,
Maintenance and Inspection) and take corrective action.
• Enable the online change setting on the Built-in Ethernet port
tab of PLC parameter in GX Developer and write data to the
CPU module.
• Change the status of the CPU module to STOP and write data.
• Set the communication data code to binary code and restart the
QnUDE(H)CPU for communication.
• Correct the send data on the external device side and resend
the data.
Correct the number of device points for reading/writing and resend
the data to the QnUDE(H)CPU.
Correct the start address or the number of device points for
reading/writing, and resend the data to the QnUDE(H)CPU.
(Do not exceed the allowable address range.)
Check and correct the text data or the request data length of the
header data, and resend the data to the QnUDE(H)CPU.
• Check the request data.
• Use commands and/or subcommands supported in the
QnUDE(H)CPU.
Check the device for reading/writing data.
Correct the request data (such as subcommand correction) and
resend the data to the QnUDE(H)CPU.
Perform the monitor registration before monitor operation.
• Correct the network number, PC number, request destination
module I/O number, and request destination module station
number.
• Correct the read/write request data.
Correct the request data and resend the data to the
QnUDE(H)CPU.
Check and correct the text data or the request data length of the
header data, and resend the data to the QnUDE(H)CPU.
• Send request messages corresponding to the communication
data code setting.
• Set the communication data code corresponding to the request
message.
Read/Write data to the device memory without specifying the
extension.
• Check the request data.
• Stop the current request.
Check the remote password and perform unlock/lock processing
again.
Perform remote password unlock processing before
communication.
Have the same external device which has requested unlock
processing request remote password lock processing.
