I - 55
A01 MULTI CPU ERROR 2302
Details
- A memory card that cannot be used with the CPU module has been installed.
Remedy
- Format memory card.
- Reformat memory card.
- Check memory card.
A01 MULTI CPU ERROR 2400
Details
- The file designated at the PLC file settings in the parameters cannot be found.
Remedy
- Read the individual information of the error using a programming tool, check to be sure that
the parameter drive name and file name correspond to the numerical values there (param-
eter number), and correct.
- Create a file created using parameters, and load it to the CPU module.
A01 MULTI CPU ERROR 2401
Details
- Program memory capacity was exceeded by performing boot operation.
Remedy
- Check and correct the parameters (boot setting).
- Delete unnecessary files in the program memory.
- Choose "Clear program memory" for boot in the parameter so that boot is started after the
program memory is cleared.
Details
- The file designated by the parameter cannot be created (even during the boot operation).
Remedy
- Read the individual information of the error using a programming tool, check to be sure that
the parameter drive name and file name correspond to the numerical values there (param-
eter number), and correct.
- Check the space remaining in the memory card.
A01 MULTI CPU ERROR 2410
Details
- The specified program does not exist in the program memory.
- The file specified by the sequence program does not exist.
Remedy
- Read the individual information of the error using a programming tool, 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.
A01 MULTI CPU ERROR 2411
Details
- The file is a comment file or the like, which cannot be designated by the sequence program.
- The specified program exists in the program memory, but has not been registered in the pro-
gram setting of the Parameter dialog box.
(This error may occur when the ECALL, EFCALL, PSTOP, PSCAN, POFF or PLOW instruc-
tion is executed.)
Remedy
- Read the individual information of the error using a programming tool, check to be sure that
the program corresponds to the numerical values there (program location), and correct.
A01 MULTI CPU ERROR 2500
Details
- There is a program file that uses a device that is out of the range set in the PLC parameter
device setting.
- After the PLC parameter device setting is changed, only the parameter is written into the
PLC.
Remedy
- Read the common information of the error using a programming tool, 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.
Details
- After the PLC parameter index modification setting is changed, only the parameter is written
into the PLC.
Remedy
- If PLC parameter index modification setting is changed, batch-write the parameter and pro-
gram file into the PLC.
A01 MULTI CPU ERROR 2501
Details
- There are multiple program files although "none" has been set at the PLC parameter pro-
gram settings.
Remedy
- Edit the PLC parameter program setting to "yes".
Alternatively, delete unneeded programs.
A01 MULTI CPU ERROR 2502
Details
- The program file is incorrect.
Alternatively, the file contents are not those of a sequence program.
Remedy
- Check whether the program version is ***.QPG, and check the file contents to be sure they
are for a sequence program.
A01 MULTI CPU ERROR 2503
Details
- There are no program files at all.
(The common information displays the drive name only.)
Remedy
- Check program configuration.
- Check parameters and program configuration.
