Description
• The system watchdog timer managed by
the system detected an error.
Alternatively, an error occurred in system
software.
• The system WDT monitoring 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.
• The operation that increase the CPU
usage rate of the system task (writing
parameter) was performed.
• The station on which the station-based
block data assurance setting is enabled
on the network has been accessed when
the stop error occurred.
• MELIPC is uncontrollable or damaged
(malfunction from noise, or hardware
fault).

Corrective action
• Reset the system. Lower the CPU
utilization of tasks with high CPU
utilization. Alternatively, do not run them.
• Review the user program.
• Set a sufficiently long system WDT
monitoring time after consideration of the
CPU utilization of the system tasks.
• Review the user program to prevent the
station on which the station-based block
data assurance setting is enabled from
being accessed when the stop error
occurred.
• Take measures to reduce noise.
• Confirm that the ambient environment is
within general specifications.
• When starting this product, ensure that
the BIOS settings screen does not start.
If the same error is displayed again, this
may indicate a hardware fault. Consult your
local Mitsubishi representative.
• Reset the system.
• Lower the CPU usage rate of tasks with
the higher rate, or make them inactivated.
