The system watchdog timer controlled by the system detected an
error, or an error occurred in the system software.
• The time set for the system watchdog timer is too short.
• A task of high CPU utilization is running.
• A program that will cause an error in the memory, stack, etc. was
executed.
• It debugged while online connection with Tornado or Workbench.
• The command was executed from Shell for debugging.
• Increase the system WDT time value in System settings of C
Controller setting utility.
• Decrease the CPU utilization of the task, or disable the task
operation.
• Check the user program.
• Check the command executed from Shell.
• Please consult your local Mitsubishi service center or representative,
explaining the details of the problem.

Since the WDT reset (QBF_ResetWDT function) was not executed
within the user WDT setting time, the USER WDT (watchdog timer)
controlled by the system detected an error.
Or, an error occurred in the user program.
• The user WDT setting time is too short.
• A task of high CPU utilization is running.
• A program that will cause an error in the memory, stack, etc. was
executed.
• It debugged while online connection with Tornado or Workbench.
• The command was executed from Shell for debugging.
• Increase the user WDT time set by the QBF_StartWDT function.
• Decrease the CPU utilization of the task, or disable the task
operation.
• Check the user program.
• Check the command executed from Shell.
• Please consult your local Mitsubishi service center or representative,
explaining the details of the problem.
5012
The time for link device refresh with the CC-Link IE controller network
module or MELSECNET/H module exceeded the set value (link
device refresh cycle).
• Increase the link device refresh cycle value in CC IE Control utility or
MELSECNET/H utility, or check and correct the refresh parameter
setting.
• It debugged while online connection with Tornado or Workbench.
• The command was executed from Shell for debugging.
• The C Controller module was restarted while online connection with
Tornado or Workbench (Q12DCCPU-V only).
For precautions for program debugging, refer to the following.
C Controller Module User's Manual (Utility Operation,
Programming)
• Restart the C Controller module with Workbench connection
disconnected.
• Check the command executed from Shell.
