Operation error
Description of error
The parameter contents are corrupted.
The parameter setting value exceeded the available range.
Any of the following errors exists in the written module
extended parameter setting:
• The predefined protocol setting has an error.
• The data for the set item is corrupted.
The device used for operands of the instruction exceeded the
device range.
The program contains instructions that cannot be used or
interpreted.
The operand device number range or data value set for the
S(P).CPRTCL instruction is out of range.
The instruction that is being used cannot be used in the
interruption routine program.
Description
Turns ON when an operation error occurs.
Error handling
Write the project again.
Correct the setting value of the parameter and write the
project again.
• Check the predefined protocol setting in protocol
setting data error (SD9120 to 9123), and correct the
setting. Then write the setting to the CPU module
and execute the S(P).CPRTCL instruction.
• If this error persists even after the data is rewritten,
replace the module.
Check the device range and correct the program.
• Perform a module diagnosis on the engineering tool
to check the details (program location). Check and
modify the program (step) indicated by the error
jump.
• Take measures against noise.
• Rewrite the program, reset the CPU module, and
perform RUN. If the same error persists, it may be
due to a hardware failure of the CPU module.
Contact your local Mitsubishi Electric representative.
Check the data specified by the S(P).CPRTCL
instruction.
Correct the program so that the instruction that cannot
be used in the interruption routine program is not used.
