36.4 List of Error Codes
Error details and cause
• 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.
• An error has been detected in the I/O
module or intelligent function module
when the instruction was executed.
• An error has been detected in the I/O
module or intelligent function module
during the END processing.
• An error has been detected in the I/O
module or intelligent function module.
• 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.
• An error has been detected in another
CPU module during the initial
processing.
• An error has been detected in another
CPU module when the instruction was
executed.
• An error has been detected in another
CPU module during the END
processing.
• An error has been detected in another
CPU module.
• A major error has been notified from
another CPU module.
• 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/ Action
continue
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.
Stop/ • Take measures to reduce noise.
continue • 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
Stop/
local Mitsubishi representative.

Stop/ • Take measures to reduce noise.
continue • 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.
Stop • Take measures to reduce noise.
• Reset the CPU module and run it
again. If the same error code is
displayed again, the possible
Stop/
cause is a hardware failure of the
continue
host CPU module or another CPU
module where the error has been
detected. Please consult your
local Mitsubishi representative.

of the error by executing module
diagnostics using the engineering
tool, identify the error module, and
eliminate the error cause.
