Appendix 7.10 Multi CPU Errors (A)
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.
A01 MULTI CPU ERROR 3002
Details
- The designated memory has no file register file, although “Use the following file” and no
capacity have been set for the file register in the PLC parameter, PLC file settings.
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.
