Error details and cause
status
The sum of the data refresh time and link
refresh time exceeds the set refresh cycle.
• The refresh cycle value is too short.
• The number of set refresh points is
excessive.
• A task of high CPU utilization is running.
(Ethernet communication load is high,
etc.)
Continue
The C Controller module was restarted
while online connection with CW
*5
Workbench.
For precautions for program debugging,
refer to the following.
 Setting/Monitoring Tools for the C
Controller Module Version 4 Operating
Manual
• 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.
• When CPU No.1 is a Basic model QCPU,
a "CPU (Empty)" slot is set on the right
Stop
side of the C Controller module.
• Any CPU module other than CPU No.1
was disconnected from the base unit
during operation. Or any CPU module
other than CPU No.1 was reset.
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.
Stop
• 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
Stop
compatible with the 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
Stop
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 does not meet the system requirement to
use the multiple CPU high 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).
Stop
• 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 to 2 (There is
a possibility that the module breaks down.).
Corrective action
• Increase the refresh cycle value in
Setting/monitoring tools for the C
Controller module.
• Decrease the number of set refresh
points in Setting/monitoring tools for the
C Controller module.
• Decrease the CPU utilization of the task,
or disable the task operation.
Restart the C Controller module with CW
*5
Workbench connection disconnected.
• 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.
• Check the mounting status of CPU
modules other than CPU No.1 and
whether the CPU modules were reset.
Identify the error of the CPU module and
eliminate the error cause.
• Remove the incompatible CPU module
from the main base unit.
• Replace the incompatible CPU module
with a compatible one.
• Reset the CPU module and restart it.
• If the same error is displayed again,
check the modules and replace a faulty
module.
• 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.
