Error details
The file capacity was exceeded by the write dur-
ing Run.
The remote request cannot be executed.
An attempt was made to remote-start the pro-
gram, which uses the CHK instruction, as a low
speed program.
The instruction code that cannot be handled
exists.
The write step is illegal.
A block No. outside the range was specified.
A number of blocks that exceeds the range was
specified.
A step No. that is outside the range was speci-
fied.
Step range limit exceeded
The specified sequence step No. is outside the
range.
The specified device is outside the range.
The block specification pattern and step specifi-
cation pattern were wrong.
The drive (memory) specified in SFC file opera-
tion is wrong.
The SFC program specified in SFC file operation
does not exist.
The program specified in SFC file operation is not

CHAPTER12 TROUBLESHOOTING
Corrective action
• Check the capacity of the specified program file.
• Write the program after setting the CPU module to the
STOP status.
• Reexecute after the CPU module is in a status where
the mode request can be executed.
• For remote operation, set the parameter to "Enable
remote reset".
• The program including the CHK instruction cannot be
executed at low speed. Execute again after checking
the program.
• Check whether the model of the used CPU module is
correct or not.
• The sequence program where online program change
was attempted includes the instruction that cannot be
handled by the CPU module model name set in the
project. Reexamine the sequence program and delete
that instruction.
• Write the program after setting the CPU module to the
STOP status.
• The starting position of online program change is not
specified with the correct program step No. Check
whether the used peripheral device supports the CPU
module model name and CPU module version set in
the project.
