Description
The system watchdog timer controlled by the
system detected an error, or an error occurred in
the system software.
• A task of high CPU utilization is running.
• A program that will cause an error in the
memory, stack, etc. was executed.
• An operation that increase the CPU utilization
by the system task (writing parameter) was
executed.
• The station on which the station-based block
data assurance is enabled on the network has
been accessed when the stop error occurred.
• CPU module drives recklessly or it breaks
down. (Malfunction by noise etc. and Hardware
error)
A hardware failure has been detected.
• A hardware failure has been detected.
• Specifies the invalid argument to the C
intelligent function module dedicated function
for ISR.
A hardware failure has been detected.
A hardware failure has been detected.
An error has been detected in the memory.
An error has been detected in the memory.
A hardware failure has been detected.
A hardware failure has been detected.
An error has been detected in the memory.
Corrective Action
• Reset the CPU module.
• Decrease the CPU utilization of the task, or
disable the task operation.
• Check the user program.
• Review the user program to prevent the station
on which the station-based block data
assurance is enabled from being accessed
when the stop error occurred.
• Take measures to reduce noise.
• Check that the CPU module is securely installed
in the base unit and the ambient environment is
within the general specification range.
If the same error code is still displayed again, the
possible cause is a hardware failure of the CPU
module. Please consult your local Mitsubishi
representative.
• Take measures to reduce noise.
• Reset the CPU module If the same error code is
displayed again, the possible cause is a
hardware failure of the CPU module. Please
consult your local Mitsubishi representative.
• Take measures to reduce noise.
• Reset the CPU module If the same error code is
displayed again, the possible cause is a
hardware failure of the CPU module. Please
consult your local Mitsubishi representative.
• Please review the arguments of the C intelligent
function module dedicated function for ISR.
• Take measures to reduce noise.
• Reset the CPU module If the same error code is
displayed again, the possible cause is a
hardware failure of the CPU module. Please
consult your local Mitsubishi representative.
• Take measures to reduce noise.
• Reset the CPU module If the same error code is
displayed again, the possible cause is a
hardware failure of the CPU module. Please
consult your local Mitsubishi representative.
• Take measures to reduce noise.
• Format the memory. Write all files to the CPU
module. Then, reset the CPU module If the
same error code is displayed again, the
possible cause is a hardware failure of the CPU
module. Please consult your local Mitsubishi
representative.
• Take measures to reduce noise.
