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.
A01 MULTI CPU ERROR 3000
Details
- In a multiple CPU system, the intelligent function module under control of another CPU is specified in
the interrupt pointer setting of the PLC parameter.
Remedy
- Specify the head I/O number of the intelligent function module under control of the host CPU.
- Delete the interrupt pointer setting of the parameter.
Details
- The PLC parameter settings for timer time limit setting, the RUN-PAUSE contact, the common
pointer No., number of vacant slots, system interrupt settings or service operation settings are
outside the range that can be used by the CPU module.
Remedy
- Read the detailed information of the error using a programming tool, check the parameter items
corresponding to those numerical values (parameter numbers), and correct when necessary.
- If the error is still generated following the correction of the parameter settings, the possible cause is
the memory error of the CPU module's built-in RAM, program memory or the memory card. Contact
your local service center.
Details
- [Memory card (ROM)] is designated as a drive for the file register and "Use the following file" or "Use
the same file name as the program" is selected in the PLC file settings, while ATA card is actually set
to the PC card slot.
Remedy
- Read the detailed information of the error using a programming tool, check the parameter items
corresponding to those numerical values (parameter numbers), and correct when necessary.
- If the error is still generated following the correction of the parameter settings, the possible cause is
the memory error of the CPU module's built-in RAM, program memory or the memory card. Contact
your local service center.
A01 MULTI CPU ERROR 3001
Details
- The parameter settings are corrupted.
Remedy
- Read the detailed information of the error using a programming tool, check the parameter items
corresponding to those numerical values (parameter numbers), and correct when necessary.
- If the error is still generated following the correction of the parameter settings, the possible cause is
the memory error of the CPU module's built-in RAM, program memory or the memory card. Contact
your local service center.
