What is the significance of the term 'Deadband' when related to tags?

The term 'Deadband' in the context of tags is indeed associated with setting limits for recording data changes. Essentially, deadband refers to a specified range within which variations or changes in the input values are ignored. This means that only changes beyond this predetermined threshold will trigger a data recording or an event.

This concept is particularly significant in monitoring systems where excessive data collection can lead to unnecessary storage use and performance overhead. By establishing a deadband, the system can reduce the frequency of recorded events or data points, ensuring that only meaningful changes—which exceed the deadband—are logged.

For example, if a sensor measures temperature and a deadband is set at one degree, minor fluctuations (such as a temperature change from 25.0 to 25.5 degrees) would not result in new data being recorded, but a change to 26.0 degrees would. This leads to more manageable data sets and can enhance the overall efficiency of the data collection process.

Using deadband effectively contributes to optimized performance and resource utilization in systems that continuously monitor changing conditions.
