What does Delta with Value Deadband record?

Delta with Value Deadband is specifically designed to capture changes in data when a tag value moves outside of a defined range, known as the deadband. This method allows for efficient data recording by focusing only on significant changes that are deemed relevant, thus reducing the amount of unnecessary data collected.

When utilizing this feature, if the value recorded does not exceed the set deadband from its last recorded value, the Historian will not log a new entry. This helps to minimize data bloat by filtering out minor fluctuations that may not be meaningful for analysis, thus ensuring that only substantial deviations are captured. This functionality is particularly beneficial in monitoring systems where noise or small variances should not trigger records, maintaining the integrity and relevance of the historical data.
