Appendix 1 Error Codes
33A1H Interrupt pointer
execution error
• The IRET instruction does not
exist in the executed interrupt
program.
• The STOP instruction has been
executed in an interrupt 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.

33A2H • The IRET instruction exists before
the FEND instruction in the main
program.
33A3H • The IRET instruction or STOP
instruction was executed in the
fixed scan execution type
program.
33A4H • The IRET instruction or STOP
instruction has been executed in
an event execution type program.
33C0H FB/FUN
execution error
• Before the FB/FUN program ends,
the call source program ended.
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.

result of the instruction that
concatenate character strings
exceeded the allowable number of
characters.)
3420H • 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.
