36 ERROR CODES
36.4 List of Error Codes
3221H SFC program
execution error
• Unable to execute the SFC program. 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.

3222H
3300H Pointer setting
error
• 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).
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.

exceeded the points set in the CPU
parameters (pointer-type label
assignment area).
Stop • Check the detailed information
(error location information) of the
error by executing module

3302H Pointer setting
error
• 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.)
Stop • Check the detailed information
(error location information) of the
error by executing module

3320H Interrupt pointer
setting error
• The interrupt pointer numbers used in
the files are overlapping.
3340H FOR-NEXT
