Which data acquisition process records at defined intervals regardless of value change?

The process that records data at defined intervals regardless of value change is known as cyclic data acquisition. This method focuses on periodically capturing data at set time intervals, ensuring that data is logged systematically over time. The main advantage of cyclic recording is that it provides a consistent and uniform dataset, which can be crucial for trend analysis, reporting, and historical data comparison.

In contrast, delta recording only logs data when a change in value occurs, which means that if a parameter does not change, no data will be recorded during that time. Forced recording refers to a manual initiation of data logging, often used to capture specific events or conditions on demand, while delta with value deadband involves recording data only when changes exceed a certain threshold, further prioritizing significant fluctuations over regular time intervals. Thus, cyclic data acquisition is uniquely suitable for gathering data consistently over time, irrespective of whether the values are changing or not.
