A
3E00H Operation circuit
error
■CPU module, SIL2 function
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.
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.
