It turns ON when conversion data stored in memory reaches the number of sampling times set by AioSetAiEventSamplingTimes function. If the number of sampling times set by
AioSetAiEventSamplingTimes function is 0, this status will always remain OFF.
This status is turned OFF by AioResetAiMemory, AioStartAi, AioResetDevice function.
The operation varies slightly depending on the memory type.
In case of FIFO
In FIFO, conversion data existing in memory decreases when data is acquired.
This status is linked with the number of data in memory, and it changes to ON/OFF according to the conversion operation and data acquisition status.
In case of RING
In RING, conversion data in memory does not decrease even if data is acquired.
Therefore, once this status turns ON, it will not turn OFF until AioResetAiMemory, AioStartAi, AioResetDevice function is executed.
