Program memory capacity was exceeded by performing boot
operation or automatic write to standard ROM.
(1) Check and correct the parameters (boot setting).
(2) Delete unnecessary files in the program memory.
(3) Choose "Clear program memory" for boot in the parameter so
that boot is started after the program memory is cleared.

2401
The file designated at the parameter PLC RAS settings fault history
area has not been created.
Read the error individual information at the peripheral device, check
to be sure that the parameter drive name and file name correspond
to the numerical values there (parameter number), and correct.
Check the space remaining in the memory card.
2410 The file designated by the sequence program cannot be found.
Read the error individual information at the peripheral device, check
to be sure that the program corresponds to the numerical values
there (program location), and correct.
Create a file created using parameters, and load it to the CPU
module.
2411
The sequence program designated a file that cannot be designated
by the sequence program (comment file, etc.).
2412
The SFC program file is one that cannot be designated by the
sequence program.
Read the error individual information at the peripheral device, check
to be sure that the program corresponds to the numerical values
there (program location), and correct.
2413
No data has been written to the file designated by the sequence
program.
Read the error individual information at the peripheral device, check
to be sure that the program corresponds to the numerical values
there (program location), and correct.
Check to ensure that the designated file has not been write protected.
2500
There is a program file that uses a device that exceeds the device
allocation range designated by the parameter device settings.
Read the error common information at the peripheral device, check
to be sure that the parameter device allocation setting and the
program file device allocation correspond to the numerical values
there (file name), and correct if necessary.
2501
There are multiple program files although "none" has been set at
the parameter program settings.
Edit the parameter program setting to "yes".
Alternatively, delete unneeded programs.
2502
The program file is incorrect.
Alternatively, the file contents are not those of a sequence program.
Check whether the program version is .QPG, and check the
file contents to be sure they are for a sequence program.
2503
2504
There are no program files at all.
Two or more SFC normal programs or control programs have been
designated.
Check program configuration.
Check parameters and program configuration.
In a multiple CPU system, the intelligent function module under
control of another station is specified in the interrupt pointer setting
of the parameter.
(1) Specify the first I/O number of the intelligent function module
under control of the host station.
(2) Delete the interrupt pointer setting of the parameter.

3000
The parameter settings for timer time limit setting, the RUN-PAUSE
contact, the common pointer number, the general data processing,
number of vacant slots, or system interrupt settings are outside the
range that can be used by the CPU module.
3001
Parameter contents have been destroyed.

3002
When "use the following files" is selected for the file registers in the
PLC file setting parameter, the specified file does not exist though
the file register capacity has been set.
(1) Read the error detailed information at the peripheral device,
check the parameter items corresponding to the numerical
values (parameter numbers) there, and correct when necessary.
(2) If the error is still generated following the correction of the
parameter settings, it is likely that there is a memory error, either
in the internal CPU RAM/program memory or on the memory
card. Contact your nearest Mitsubishi representative.
The automatic refresh range of the multiple CPU system exceeded
the file register capacity.
Change the file register file for the one refresh-enabled in the whole
range.

3003
The number of devices set at the parameter device settings
exceeds the possible CPU module range.
(1) Read the error detailed information at the peripheral device,
check the parameter items corresponding to the numerical
values (parameter numbers) there, and correct when necessary.
(2) If the error is still generated following the correction of the
parameter settings, it is likely that there is a memory error, either
in the internal CPU RAM/program memory or on the memory
card. Contact your nearest Mitsubishi representative.
3004
The parameter file is incorrect.
Alternatively, the contents of the file are not parameters.
Check whether the parameter file version is .QPA, and
check the file contents to be sure they are parameters.
3006
(1) The high speed interrupt parameter is set in a Q02CPU.
(2) The high speed parameter is set in a multiple CPU system.
(3) The high speed interrupt parameter is set when a QA1S
B or
QA
B is used.
(4) No module is installed at the I/O address designated by the high
speed interrupt parameter.
(1) Delete the setting of the Q02CPU’s high speed interrupt
parameter. To use high speed interrupts, change the CPU
module to one of the Q02H/Q06H/Q12H/Q25HCPU.
(2) To use a multiple CPU system, delete the setting of the high-
speed interrupt parameter. To use high speed interrupts, change
the system to a single PLC system.
(3) To use either the QA1S
B or QA B, delete the setting of the
high speed interrupt parameter. To use high speed interrupts, do
not use the QA1S
B/QA B.
(4) Re-examine the I/O address designated by the high speed
interrupt parameter.

3009 A modules are set to control PLCs in a multiple CPU system.
Re-set the parameter I/O assignment to control them under one
QCPU. (Change the parameters of all stations in the multiple CPU
system.)
3010
The parameter-set number of CPU modules differs from the actual
number in a multiple CPU system.
Match (preset count of multiple PLC setting) - (CPU (empty) setting
in I/O assignment) with the actual number of CPUs loaded.
3012
Multiple CPU setting or control PLC setting differs from that of the
reference station in a multiple CPU system.
Match the multiple PLC setting or control CPU setting in the
parameter with that of the reference station (station 1).
3013
Multiple CPU automatic refresh setting is any of the followings in a
multiple CPU system.
(1) When a bit device is specified as a refresh device, a number
other than a multiple of 16 is specified for the refresh-starting
device.
(2) The device specified is other than the one that may be specified.
(3) The number of send points is an odd number.
Check the following in the multiple CPU automatic refresh
parameters and make correction.
(1) When specifying the bit device, specify a multiple of 16 for the
refresh starting device.
(2) Specify the device that may be specified for the refresh device.
(3) Set the number of send points to an even number.
