36 ERROR CODES
36.4 List of Error Codes
2440H Module major
error
• In a multiple CPU system, the 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 • 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.

2441H Module major
error
• An error has been detected in the I/O
module or intelligent function module
when the instruction was executed.
Stop/
continue
• 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.

2450H Module major
error
• A major error has been notified from
the intelligent function module
connected.
• The I/O module or intelligent function
module is not mounted properly or
was removed during operation.
Stop/
continue
• Take measures to reduce noise.
• Check the connection status of the
extension cable.
• Check the detailed information
(system configuration information)
of the error by executing module
diagnostics using the engineering
tool and check the module
corresponding to the displayed
slot number.
• 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.

2460H Another CPU
module major
error
• An error has been detected in another
CPU module during the initial
processing.
Stop • 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
host CPU module or another CPU
module where the error has been
detected. Please consult your
local Mitsubishi representative.

2480H Multiple CPU
error
• In a multiple CPU system, an error
has been detected in the CPU module
where "Stop" is set in the operation
mode setting parameter.
• Any CPU module other than CPU
No.1 is mounted in the inapplicable
slot.
(An error occurs in the CPU module
mounted in the inapplicable slot.)
Stop • Check the detailed information
(system configuration information)
of the error by executing module
diagnostics using the engineering
tool, identify the error module, and
eliminate the error cause.
• Remove the CPU module from the
inapplicable slot.
