Appendix 1 Error Codes
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.

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.

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.

2481H Multiple CPU
error
• In a multiple CPU system, any
CPU module other than CPU No.1
was disconnected from the base
unit during operation. Or, any CPU
module other than CPU No.1 was
reset.
Stop • Check the mounting status and reset
status of the CPU modules other than
CPU No.1.
