NI InsightCM Server treats data acquisitions differently depending on whether they occur during any stream-enabled operating state, such as a run-up or coast-down. Any acquisition that is not part of a stream is categorized as a periodic acquisition. The following table describes some of the differences between periodic and stream acquisitions.
