Error Error name Error details and cause
code
3E00H Operation circuit ■CPU module, SIL2 function
error module, safety function module
• An error has been detected in the
CPU module, SIL2 function
module, or safety function module.
■Redundant function module
• An error has been detected in the
redundant function module.
3E01H Operation circuit • An error has been detected in the
error CPU module, SIL2 function
module, or safety function module.
3E10H Circuit error • An error has been detected in the
CPU module, SIL2 function
3E11H
module, or safety function module.
3E12H
3E20H Program • The entire program was executed
execution error without executing the END
instruction.
3E22H Program • The FB/FUN program did not
execution error complete successfully.
Stop/ Action
continue
Stop ■CPU module, SIL2 function module,
safety function module
• Take measures to reduce noise.
• Check the mounting status of the CPU
module, SIL2 function module, and
safety function module.
• Format the memory. Write all files to
the CPU module. 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.
■Redundant function module
• Reset the CPU module.
• If the error code is displayed again
even after taking an action, please
consult your local Mitsubishi
representative.
Stop • Take measures to reduce noise.
• Check the mounting status of the CPU
module, SIL2 function module, and
safety function module.
• Format the memory. Write all files to
the CPU module. 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.
