9.7.1 For Q12DCCPU-V
(a) When downloading by specifying the user program from Workbench
A system error or stop (such as a system watchdog timer error) may occur in the
C Controller module during downloading if the program is too large.
When a system error or stop (such as a system watchdog timer error) has
occurred, take either of the following measures.
• Increase the value of "WDT (watchdog timer) setting" on the System settings
tab of the C Controller setting utility.
• Load the program in the C Controller module before debugging.
An interrupt to the C Controller module may be disabled during debugging.
During the time, processing called from an interrupt routine (interrupt program)
(example: bus interface functions for ISR) is not executed.
Interrupts that are expected to occur at fixed intervals, such as multiple CPU
synchronous interrupt, may delay. For debugging from Workbench, pay attention
to the above.
(b) When restarting the C Controller module
Before restarting the C Controller module, disconnect the connection with
Workbench.
Failure to do so may cause an error in the C Controller module.
