Error Error name Error details and cause
code
3C10H Hardware failure • A hardware failure has been
detected.
3C11H
3C12H Hardware failure • The waveform of the voltage out
of the specified range has been
detected in the power supply
module.
• A hardware failure has been
detected in the power supply
module, CPU module, base unit,
or extension cable. (In a
redundant power supply system,
the error is detected when two
power supply modules failed.)
3C13H Hardware failure • A hardware failure has been
detected.
3C14H Hardware failure • A hardware failure has been
detected.
3C15H Hardware failure • A hardware failure has been
detected.

Stop ■CPU module
• Take measures to reduce noise.
• Check the mounting status of the CPU
module, SIL2 function module, and
safety function module.
• 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
• The possible cause is malfunction due
to noise. Take measures to reduce
noise by checking the distance of wires
and cables, and the grounding status of
each device.
• Execute a module communication test.
If the same error code is displayed
again, the possible cause is a
hardware failure of the redundant
function module. Please consult your
local Mitsubishi representative.
Stop • Check the waveform of the voltage
applied to the power supply module.
• Check the mounting status of the CPU
module.
• 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 power supply
module, CPU module, base unit, or
extension cable. Please consult your
local Mitsubishi representative.
