I - 63
A01 MULTI CPU ERROR 7004
Details
- In a multiple CPU system, a data error occurred in communication between the CPU mod-
ules.
Remedy
- Check the system configuration to see if modules are mounted in excess of the number of
I/O points.
- When there are no problems in the system configuration, this indicates the CPU module
hardware s faulty. Contact your local service center.
A01 MULTI CPU ERROR 7010
Details
- In a multiple CPU system, a faulty CPU module was mounted.
- In a multiple CPU system, a CPU module incompatible with the multiple CPU system was
mounted.
(The CPU module compatible with the multiple CPU system was used to detect an error.)
Remedy
- Read the individual information of the error using GX Developer, and replace the faulty CPU
module.
A01 MULTI CPU ERROR 7011
Details
Either of the following settings was made in a multiple CPU system.
- Multiple CPU automatic refresh setting was made for the inapplicable CPU module.
- 'I/O sharing when using multiple CPUs' setting was made for the inapplicable CPU module.
Remedy
- Replace the CPU module to the one applicable to the 'I/O sharing when using multiple
CPUs'.
Details
The system configuration is not applicable to the multi-CPUs high-speed communication.
- QnUD(H)CPU is not used for CPU No.1.
- Main base module for multi-CPUs high-speed communication (Q3(DB) is not used.
Remedy
- Change the system configuration to be applicable to the multi-CPUs high-speed communi-
cation.
A01 MULTI CPU ERROR 7012
Details
The CPU module that cannot configure QnUD(H)CPU nor multi-CPU system is mounted on
the CPU slot or slot No. 0 to 2.
- Qn(H)CPU or QnPHCPU is mounted.
- PC CPU or C language-based controller is mounted.
Remedy
- Remove the CPU module that does not support QnUD(H)CPU.
A01 MULTI CPU ERROR 7013
Details
- The motion CPU (Q172/3(H)CPU(N)), which cannot configure QnUD(H)CPU nor multi-CPU
system, is mounted to the CPU slot or slot No. 0 to 2.
(Note) This error may lead the module failure.
Remedy
- Remove the CPU module that does not support QnUD(H)CPU.
A01 MULTI CPU ERROR 7020
Details
- In the operating mode of a multiple CPU system, an error occurred in the CPU where "sys-
tem stop" was not selected.
(The CPU module where no error occurred was used to detect an error.)
Remedy
- Read the individual information of the error using a programming tool, check the error of the
CPU module resulting in CPU module fault, and remove the error.
A01 MULTI CPU ERROR 7030
Details
- An assignment error occurred in the CPU-mountable slot (CPU slot, I/O slot 0, 1) in excess
of the number of CPU modules specified in the multiple CPU setting of the PLC parameter
dialog box.
Remedy
- Set the same value to the number of CPU modules specified in the multiple CPU setting of
the PLC parameter dialog box and the number of mounted CPU modules (including CPU
(empty)).
- Make the type specified in the I/O assignment setting of the PLC parameter dialog box con-
sistent with the CPU module configuration.
A01 MULTI CPU ERROR 7031
Details
- An assignment error occurred within the range of the number of CPUs specified in the mul-
tiple CPU setting of the PLC parameter dialog box.
Remedy
- Set the same value to the number of CPU modules specified in the multiple CPU setting of
the PLC parameter dialog box and the number of mounted CPU modules (including CPU
(empty)).
- Make the type specified in the I/O assignment setting of the PLC parameter dialog box con-
sistent with the CPU module configuration.
A01 MULTI CPU ERROR 7035
Details
- The CPU module has been mounted on the inapplicable slot.
Remedy
- Mount the CPU module on the applicable slot (CPU slot or I/O slot 0, 1).
- Remove the CPU from the inapplicable slot.
