36 ERROR CODES
36.4 List of Error Codes
3141H FB/FUN
program error
• The structure of FB/FUN program is
incorrect.
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.

3142H Temporary area
error
• The temporary area was used
incorrectly.
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.

SFC program
block, step error
• The SFC program configuration is
illegal.
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.
