8 TROUBLESHOOTING
Error Code
Error Contents and Cause
*1
(SD0)
The specified program does not exist in the program
memory.
2410
This error may occur when the ECALL, EFCALL, PSTOP,
PSCAN, POFF or PLOW instruction is executed.
The specified program exists in the program memory, but
has not been registered in the program setting of the
2411
Parameter dialog box. This error may occur when the
ECALL, EFCALL, PSTOP, PSCAN, POFF or PLOW
instruction is executed.
The SFC program file is one that cannot be designated by
2412
the sequence program.
No data has been written to the file designated by the
2413
sequence program.
• There is a program file that uses a device that is out of
the range set in the PLC parameter device setting.
2500
• After the PLC parameter setting is changed, only the
parameter is written into the PLC.
There are multiple program files although "none" has
been set at the PLC parameter program settings.
2501
• There are three or more program files.
• The program name differs from the program contents.
The program file is incorrect.
Alternatively, the file contents are not those of a sequence
program.
2502
The program file is not the one for the redundant CPU.
2503
There are no program files at all.
Two or more SFC normal programs or control programs
have been designated.
2504
There are two or more SFC programs.
*1
: Characters in parentheses ( ) indicate the special register numbers where individual information is being stored.
*12 : This applies to the CPU of function version B or later.

Corrective Action
Read the individual information of the error using 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.
Read the individual information of the error using the
peripheral device, check to be sure that the program
corresponds to the numerical values there (program
location), and correct.
Read the individual information of the error using the
peripheral device, check to be sure that the program
corresponds to the numerical values there (program
location), and correct.
Read the individual information of the error using 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.
• Read the common information of the error using 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.
• If PLC parameter device setting is changed, batch-write
the parameter and program file into the PLC.
Edit the PLC parameter program setting to "yes".
Alternatively, delete unneeded programs.
• Delete unnecessary program files.
• Match the program name with the program contents.
Check whether the program version is
check the file contents to be sure they are for a sequence
program.
Create a program using GX Developer or PX Developer
for which the PLC type has been set to the redundant
CPU (Q12PRH/Q25PRH), and write it to the CPU
module.
• Check program configuration.
• Check parameters and program configuration.
Reduce the SFC programs to one.
