Appendix 1 Error Codes
3100H
Program error
• The program includes any
instruction that cannot be used or
decoded in the CPU module.
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.

Program error
• The program contains a dedicated
SFC program instruction even
although it is not an SFC 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.
• 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
or module (SIL2 function module or
safety function module) connected.
Please consult your local Mitsubishi
representative.
