Precautions
• When an interrupt event has already been notified from a programmable controller CPU module (another CPU module) at
the time of the CCPU_WaitEvent function execution, the user program is restored from the interrupt event wait state at the
same time as the function execution. In addition, when multiple interrupt events have been notified to the same interrupt
event number at the time of the CCPU_WaitEvent function execution, the user program processes them as a single
interrupt event notification.
• If the same CPU number and the same interrupt event number are set in more than one user program, it will be undefined
which one of the user programs receives the interrupt event.
