36.4 List of Error Codes
Error details and cause
• The structure of FB/FUN program is
incorrect.
• The temporary area was used
incorrectly.
• The SFC program configuration is
illegal.
• The number of SFC program steps
exceeds the total number of step
relays (S).
• The total number of SFC program
blocks (max. step No. + 1) exceeds
the total number of step relays (S).
• The SFC program configuration is
illegal.
Stop/ Action
continue
Stop • Take measures to reduce noise.
• Write the sequence program(s)
and FB program(s) 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 check the program.
• Take measures to reduce noise.
• Write the sequence program(s)
and FB program(s) 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 • 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 • Correct the program so that the
number of SFC program steps
does not exceed the total number
of step relays (S).
• Check and correct the number of
device setting step relays (S) in
the CPU parameters.
Stop • Correct the program so that the
total number of SFC program
blocks (max. step No. + 1) does
not exceed the total number of
step relays (S).
• Check and correct the number of
device setting step relays (S) in
the CPU parameters.
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.
