What is the purpose of adjusting storage deadband for a tag?

Adjusting the storage deadband for a tag serves the specific purpose of reducing data storage needs within an AVEVA Historian environment. The storage deadband is a threshold that defines the minimum change in value that a tag must experience before a new value is recorded in the database. This means that if the changes in the data are less than the specified deadband value, those changes will not trigger a new data point to be stored.

By implementing a storage deadband, you can prevent the storage of insignificant or minor fluctuations in the data, which often do not contribute meaningful information for analysis. This results in a more streamlined dataset that saves storage space and improves the efficiency of data retrieval and processing.

While other options like enhancing data visualization and increasing data accuracy are critical aspects of data management, they aren't directly related to the function of storage deadband in terms of data collection frequency or the amount of data stored. This makes the focus on reducing data storage needs the most relevant outcome of adjusting the storage deadband.
