Appendix 1.11
If an error occurs at communication request from a programming tool, intelligent function module, or network system,
the CPU module returns the error code to the request source.
This error code is not stored in SD0 because the error is not the one detected by the self-diagnostic function of the
CPU module.
When the request source is a programming tool, a message and an error code are displayed on the programming tool.
When the request source is an intelligent function module or network system, the CPU module returns an error code to
the request source.

Error details
A code different from the one specified is set to
the command/response type of the subheader.
Serial communication sum check error
Unsupported request was executed.
Unsupported request was executed.
Command for which a global request cannot be
performed was executed.
Any operation for the CPU module is prohibited
by the system protect function provided against
the following events.
• The system protect switch is ON.
• The CPU module is starting.
The volume of data handled according to the
specified request is too large.
Initial communication failed.
The CPU module is BUSY. (The buffer is not
vacant).
Since the CPU module is running, the request
contents cannot be executed.
Since the CPU module is not in a STOP status,
the request contents cannot be executed.
The specified drive memory does not exist or
there is an error.
The file with the specified file name or file No.
does not exist.
Corrective action
• Check the command data of the MC protocol,
etc.
• Execute again. If the same error code is
displayed, please consult your local Mitsubishi
representative.
• Connect the serial communication cable
correctly.
• Take measures to reduce noise.
• Check the command data of the MC protocol,
etc.
• Check the CPU module model name selected in
the programming tool.
• Check the command data of the MC protocol,
etc.
• Check the CPU module model name selected in
the programming tool.
• Execute again. If the same error code is
displayed, please consult your local Mitsubishi
representative.
Check the command data of the MC protocol, etc.
• Set the system protect switch of the CPU
module to OFF.
• Perform operation again after the CPU module
has completed starting.
Check the command data of the MC protocol, etc.
• When using serial communication, inquire of the
external device manufacturer for support
conditions.
• When using serial communication, check the
CPU module model name selected in the
programming tool.
• When using Ethernet communication, change
the start timing of the communication.
After the free time has passed, re-execute the
request.
Execute after setting the CPU module to STOP
status.
Execute after setting the CPU module to STOP
status.
• Check the specified drive memory status.
• After backing up the data in the CPU module,
format the CPU memory.
Check the specified file name and file No.
