36.4 List of Error Codes
Error details and cause
• Unable to execute the SFC program.
• The total number of points of local or
global pointers used in the program
exceeded the points set in the CPU
parameters (pointer device area).
• The total number of points of pointer-
type labels used in the program
exceeded the points set in the CPU
parameters (pointer-type label
assignment area).
• Multiple global pointers with the same
number or pointer-type global labels
are used in the program. (The pointer
numbers or the labels are
overlapping.)
• Multiple local pointers with the same
number or pointer-type local labels
are used in the program. (The pointer
numbers or the labels are
overlapping.)
• The interrupt pointer numbers used in
the files are overlapping.
• The NEXT instruction was not
executed even though the FOR
instruction was executed. Or, there
are more FOR instructions than NEXT
instructions.
• The NEXT instruction was executed
even though the FOR instruction was
not executed. Or, there are more
NEXT instructions than FOR
instructions.
• The BREAK instruction was executed
even though the FOR instruction was
not executed.
• The number of nesting levels in the
subroutine program exceeded its limit
(16).
• The number of nesting levels in the
FOR instruction exceeded its limit
(16).
• The number of nesting levels in the DI
instruction exceeded its limit (16).
Stop/ Action
continue
Stop • Take measures to reduce noise.
• Write the SFC 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. 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 program.
• Check and correct the pointer
device area point setting in the
CPU parameters.
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.
• Check and correct the pointer-type
label assignment area point
setting in the CPU parameters.
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 number of
nesting levels (16 or less).
