Appendix 1 Error Codes
Error details and cause
• The IRET instruction does not
exist in the executed interrupt
program.
• The STOP instruction has been
executed in an interrupt program.
• The IRET instruction exists before
the FEND instruction in the main
program.
• The IRET instruction or STOP
instruction was executed in the
fixed scan execution type
program.
• The IRET instruction or STOP
instruction has been executed in
an event execution type program.
• Before the FB/FUN program ends,
the call source program ended.
• The secured temporary area size
exceeded its limit.
• Division where the divisor is zero
was performed.
• Data that cannot be converted by
using the data conversion
instruction was input.
• The operation was performed with
the invalid data (-0, denormalized
number, NaN (not a number), or
).
• An overflow has occurred during
the operation.
• A string that is not supported in
the instruction was specified.
• The input data was out of range.
• The operation result is out of the
output range. (The operation
result of the instruction that
concatenate character strings
exceeded the allowable number of
characters.)
• The link direct device, module
access device, or CPU buffer
memory access device is
specified for both (s) and (d) used
in the BMOV instruction.
Stop/ Action
continue
Stop • Check the detailed information (error
location information) of the error by
executing module diagnostics using
the engineering tool, display the error
program (step) by clicking the [Error
Jump] button, and correct the program.
Stop • Check the detailed information (error
location information) of the error by
executing module diagnostics using
the engineering tool, display the error
program (step) by clicking the [Error
Jump] button, and correct the program.
• Take measures to reduce noise.
• Write the program to the CPU module
again. Then, 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 or module (SIL2 function
module or safety function module)
connected. Please consult your local
Mitsubishi representative.
Stop • Check the detailed information (error
location information) of the error by
executing module diagnostics using
the engineering tool, display the error
program (step) by clicking the [Error
Jump] button, and correct the number
of nesting levels in the function.
Stop/ • Check the detailed information (error
continue location information) of the error by
executing module diagnostics using
the engineering tool, display the error
program (step) by clicking the [Error
Jump] button, and correct the program.
