TROUBLESHOOTING
Error code
• In the operating mode of the multiple CPU system, a CPU error
occurred in the CPU for which "All station stop by stop error of CPU"
is selected.
• In the multiple CPU system, a CPU module incompatible with the
multiple CPU system is mounted.
7000
• When CPU No.1 is a Basic model QCPU, a "CPU (Empty)" slot is set
on the right side of the C Controller module.
In the multiple CPU system, a stop error occurred in CPU No.1 during
power-on, and thereby the other CPUs (No.2 to No.4) cannot start.
• During the initial communication in the multiple CPU system, no
response returns from the target CPU.
7002
• In the multiple CPU system, a CPU module incompatible with the
multiple CPU system is mounted.
• In the multiple CPU system, a faulty CPU module is mounted.
• In the multiple CPU system, a CPU module incompatible with the
multiple CPU system is mounted. (A CPU module compatible with the
7010 multiple CPU system detects this error.)
• In the multiple CPU system, any of the CPU No.2 to No.4 was reset
with power ON. (A CPU that released from the reset status detects
this error.)
In a multiple CPU system, the either of following setting was set.
• Set the multiple CPU auto refresh setting to the CPU module that
cannot execute the multiple CPU auto refresh setting.
• Set the I/O sharing when using Multiple CPUs to the CPU module
that cannot read the I/O of outside of the group.
It doesn't meet the system requirement to use the multiple CPU high
7011 speed transmission.
• It is not used QnUD(H)CPU or QnDCCPU in CPU No.1.
• It is not used the multiple CPU high speed main base unit (Q3 DB).
• The send range is set excluding 0 point to the CPU module that is not
supported the multiple CPU high speed transmission.
• The send range is set excluding 0 point to the CPU module that is not
supported the multiple CPU interchangeability area.
Q172(H)CPU(N) or Q173(H)CPU(N) is installed in CPU slot and slot 0
7013
to 2 (There is a possibility that the module breaks down.).
In the operating mode of the multiple CPU system, an error occurred
7020 in the CPU for which "All station stop by stop error of CPU" is not
selected. (A normal CPU module detects this error.)
The number of connected CPU set in the multiple CPU setting doesn't
7036 match the number of connected CPU that is decided according to
fixing point of CPU module.
Error details and cause
16.3 Actions to be Taken When the ERR. LED is On or Flashing
Corrective action
• Identify the error of the CPU module and eliminate the error cause.
• Remove the incompatible CPU module from the main base unit.
• Change the setting.
Identify the error of the CPU module and eliminate the error cause.
• Reset the CPU module and restart it. If the same error is displayed
again, either of the CPU modules is faulty. Please consult your local
Mitsubishi service center or representative, explaining the details of
the problem.
• Remove the incompatible CPU module from the main base unit.
Or, replace the incompatible CPU module with a compatible one.
• Replace the faulty CPU.
• Replace it with a CPU module that is compatible with the multiple
CPU system.
• Do not reset any of CPU No.2 to No.4.
• Reset CPU No.1 and restart the multiple CPU system.
• Correct the multiple CPU automatic refresh setting.
• Correct the "I/O sharing when using multiple CPUs" setting.
• Change the system configuration so that the conditions for using the
multiple CPU high speed transmission function are met.
• When performing automatic refresh in the multiple CPU compatible
area, set the send range of a CPU that does not support the function
to zero points.
Check QCPUs and Motion CPUs that can be used in multiple CPU
systems, and change the system configuration.
Identify the error of the CPU module, and eliminate the error.
• Mount the CPU module in the correct slot.
• Change the host CPU No. set in the multiple CPU setting to the one
determined by the mounting position of the CPU module.
