Description
The user WDT managed by the system
detected an error because
CCPU_ResetWDT was not executed within
the user WDT setting time of the VxWorks
part. Alternatively, an error occurred with a
user program.
• The user WDT setting time is short.
• Tasks with the higher CPU usage rate is
in operation.
• A program causing an error in the
memory or stack was executed.
• Debugging was performed with CW
Workbench 4 connected online.
• Command was executed from Shell for
debugging.
• The following functions that increase the
CPU usage rate of the system task are
used.
(1) Ethernet communication
(2) File sharing service
A command in the script file of the VxWorks
part cannot be executed. (The syntax is
incorrect or no command exists.)
Fan rotational speed has dropped below
specified values.
A hardware failure was detected.
A hardware failure was detected.
• A hardware failure was detected.
• An invalid argument has been specified
with the C Controller module dedicated
functions for ISR.
A hardware failure was detected.
A memory error was detected.
An error was detected in the memory.
An error was detected in the memory.
Corrective action
• Lower the CPU utilization of tasks with
high CPU utilization on the VxWorks part.
Alternatively, do not run them.
• Review the user programs of the
VxWorks part.
• Restart with CW Workbench 4 on the
VxWorks part not connected online.
• Review the command executed from
Shell on the VxWorks part.
• Reset the MELIPC.
• Set a sufficiently long user WDT setting
time after consideration of the CPU
utilization of the system tasks of the
VxWorks part.
• If the issue is still not resolved, replace
the MELIPC.
Check whether the syntax of the script file
that had the error on the VxWorks part is
correct and that a command exists.
• Check that the fan module is installed
correctly.
• Replace the fan module.
• If the same error is displayed again, this
may indicate a hardware fault. Consult
your local Mitsubishi representative.
• Take measures to reduce noise.
• Reset the system. If the same error is
displayed again, this may indicate a
hardware fault. Consult your local
Mitsubishi representative.
