Error Error name Error details and cause
code
2320H Remote • The start I/O number of the
password remote password target module is
setting error set to other than 0H to 0FF0H.
• There is a problem on the slot
specified by the start I/O number
of the remote password setting.
(1) No module is mounted.
(2) The mounted intelligent function
module does not support the
remote password setting.
2321H Remote • In a multiple CPU system, the
password module controlled by another CPU
setting error module is specified by the start I/O
number of the remote password
setting.
2400H Module • The module information at power-
verification error on differs from the information of
modules actually mounted.
• The I/O module or intelligent
function module is not mounted
properly or was removed during
operation.
2401H Module • A CPU module, I/O module, or
verification error intelligent function module was
mounted on the base unit during
operation.
2420H Fuse blown • The output module with a blown
error fuse has been detected.
2440H Module major • In a multiple CPU system, the
error control CPU setting in the system
parameters is different from that of
other CPU modules.
• In a multiple CPU system, other
CPU modules (SIL2 Process CPU
or Safety CPU) have detected a
parameter verification error.
• An error has been detected in the
I/O module or intelligent function
module during the initial
processing.
Stop/ Action
continue
Stop • Set the start I/O number of the remote
password target module within the
range 0H to 0FF0H.
• On the specified slot, mount an
intelligent function module that
supports the remote password setting.
Stop • Check and correct the remote
password setting.
Stop/ • Check the detailed information (system
continue configuration information) of the error
by executing module diagnostics using
the engineering tool and check the
module corresponding to the displayed
slot number.
• Take measures to reduce noise.
• 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 error module.
Please consult your local Mitsubishi
representative.
Stop/ • Check the detailed information (system
continue configuration information) of the error
by executing module diagnostics using
the engineering tool and check the
module corresponding to the displayed
slot number.
• Do not mount a CPU module, I/O
module, nor intelligent function module
during operation.
• Take measures to reduce noise.
• 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 error module.
Please consult your local Mitsubishi
representative.
Stop/ • Check the FUSE LED of each output
continue module, and replace the one with the
FUSE LED on.
• Check the detailed information (system
configuration information) of the error
by executing module diagnostics using
the engineering tool, and replace the
module corresponding to the displayed
slot number.
Stop • Correct the system parameter settings
for the CPU No.2 and later in
accordance with those of the CPU
No.1.
• Eliminate the error cause of another
CPU module (Safety CPU or SIL2
Process CPU).
• Take measures to reduce noise.
• 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 error module.
Please consult your local Mitsubishi
representative.
