Appendix 1 Error Codes
Error details and cause
• Even though an interrupt was
requested, there is no interrupt
factor.
• An interrupt was requested from
the module with no interrupt
pointer setting.
• An execution interval error of the
synchronization interrupt program
has been detected.
• An inter-module synchronization
error has been detected.
• An inter-module synchronization
error has been detected.
• An execution interval error of the
synchronization interrupt program
has been detected.
• A multiple CPU synchronization
error has been detected.
• A multiple CPU synchronization
error has been detected.
• The specified I/O number is out of
range (other than 0 to FFH, 3E0 to
3E3H).
• The I/O number of the module that
does not exist was specified.
• The I/O 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.
• The I/O number of the module that
cannot be specified in the
instruction was specified.
• The specified network number is
out of range (other than 1 to 239).
• The network number that does not
exist was specified.
Stop/ Action
continue
Stop • Take measures to reduce noise.
• Reset the CPU module and run it
again. If the same error code is
displayed again, the possible cause is
a hardware failure of the CPU module,
base unit, or module (I/O module or
intelligent function module) connected.
Please consult your local Mitsubishi
representative.
Stop • Check and correct the interrupt pointer
setting in the module parameters.
• Take measures so that no interrupt is
requested from the module with no
interrupt pointer setting.
• Check and correct the interrupt setting
in the buffer memory of the intelligent
function module.
• Correct the BASIC program executed
in the QD51.
Stop/ • Take measures to reduce noise.
continue • Reset the CPU module and run it
again. If the same error code is
displayed again, the possible cause is
a hardware failure of the CPU module,
base unit, extension cable, or module
