Appendix 3 Error Code
Error details and cause
• A module supporting remote passwords
is not connected to the module number
specified in the remote password
parameter.
• The power of a module connected is
OFF or a connection error has been
detected.
• A module was connected during
operation.
• The communication procedure with a
module failed during initial processing.
• The communication procedure with a
module failed when an instruction was
executed.
• An error has been detected in the I/O
module or intelligent function module
during the END processing.
• 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.
• The specified module number is out of
range.
• Verify that the module with the specified
module number exists.
• The module number of the module that
does not support the instruction was
specified.
• The dedicated instruction specified in the
program cannot be executed in the
specified module or mode.
• A device used as an instruction operand
is outside the allowable device range.
Action
• Recheck the remote password parameter
setting or module configuration.
• Verify that the connected module is powered
on.
• Verify that extension cables are correctly
connected.
• Implement anti-noise measures.
• If there is no problem, there may be a
malfunction in the connected module.
Replace the connected module.
• Avoid connecting a module during operation.
• Verify that extension cables are correctly
connected.
• Verify that the version of the CPU module is
compatible with the module where the error
was detected.
• If the version of the CPU module is correct,
there may be a malfunction in the connected
module. Replace the connected module.
• Review the program and check the contents
of the operands used in the applied
instructions.
• Verify that the specified buffer memory exists
in the counterpart equipment.
• Verify that extension cables are correctly
connected.
• There may be a hardware error in the faulty
module. Consult your local Mitsubishi

• 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.
• Check the detailed information (error
location information) of the error by
executing module diagnostics using the
engineering tool, display the error program
(step) by the error jump, and correct the
program.
• Specify the correct module number.
• Check the detailed information (error
location information) of the error by
executing module diagnostics using the
engineering tool, display the error program
(step) by the error jump, and correct the
program.
• Check the execution conditions (including
support status and execution mode) of the
dedicated instruction, referring to the manual
for the target module.
• Check the device range and modify the
program.
