What condition must be met for the Active Event control to be effectively utilized?

The Active Event control relies on a well-defined set of conditions to function properly, making it essential for the event configuration to include triggers. Triggers serve as specific criteria or conditions that, when met, initiate the event. This means that without appropriate triggers defined in the configuration, the Active Event control would have no basis on which to activate or respond to changes in the data, rendering it ineffective.

In practical application, triggers can relate to various data points or thresholds that, when surpassed, would signal an event. This capability enhances the control's ability to monitor and respond dynamically to real-time changes in the data collected by the Historian, ensuring that important alerts or actions can be executed automatically based on the predetermined criteria. Thus, having triggers in place is a fundamental requirement for the effective utilization of the Active Event control.
