Appendix 3 Error Code
Error details and cause
• The initial scan time exceeded the set
value of execution monitor time.
• The scan time of the second and
subsequent scans exceeded the set
value of execution monitor time.
• An interrupt request was detected from a
module that does not have an interrupt
pointer specified in the parameters.
• Verify that the module with the specified
module number exists.
• A device used as an instruction operand
is outside the allowable device range.
• There are duplicate devices used as an
instruction operand.
• A device or modification that cannot be
used as an instruction operand is used.
• Verify that the specified module has
buffer memory.
• Check the buffer memory range of the
specified module.
• Verify that the size specified from the
specified buffer memory number is within
the buffer memory range.
• The program file specified does not exist.
• An error was found in the boot file.
• Formatting failed during booting.
• A mismatch between the file password
32 of the boot source file and that of the
boot destination file was detected during
booting.
• The capacity of the boot destination data
memory becomes insufficient due to
booting.
• A mismatch between the security
information of the boot source file and
that of the boot destination file was
detected during booting.
• An error was detected when writing was
executed during RUN.
• An error was detected when writing was
executed during RUN.
• An error was detected when writing was
executed during RUN.
• An error was detected when writing was
executed during RUN.
Action
• Recheck the set value of execution monitor
time or program.
• Recheck the set value of execution monitor
time or program.
• Correctly set the interrupt pointer for module
interrupt.
• Specify the correct module number.
• Check the device range and modify the
program.
• Check the range of devices used by each
operand and modify the program.
• Check the usage of the instruction and
modify the program.
• Review the program or check the contents of
the operands used in applied instructions.
• Verify that the specified buffer memory exists
in the counterpart equipment.
• Rewrite the project.
• Replace the boot file in the SD memory card
with the correct file and turn the PLC power
ON again.
• Reset the CPU module, and then execute
the boot function again. If the same error
appears, the hardware of the CPU module
may be malfunctioning. Consult your local
Mitsubishi Electric representative.
• Check the file password 32 of the boot
source file.
• Allow sufficient capacity on the boot
destination or recheck the file size of the
boot source.
• Check the security information of the boot
source file.
• Set the CPU module to STOP and write a set
of project data.
• Set the CPU module to STOP and write a set
of project data.
• Set the CPU module to STOP and write a set
of project data.
• Set the CPU module to STOP and write a set
of project data.
