What are the defined conditions for polling in data acquisition called?

The defined conditions for polling in data acquisition are referred to as triggers. Triggers serve as specific criteria or events that initiate the polling process to collect data at regular intervals or under specific conditions. For instance, a trigger could be set to start data collection when a certain threshold is reached or at predefined time intervals.

In the context of industrial automation and IIoT, triggers are vital for efficiently managing data flow, ensuring that relevant data is captured without unnecessary overhead. This concept aligns closely with how systems need to react to dynamic environments, as effective data acquisition is dependent on defining when and why data should be gathered. Such triggers enhance the reliability of the data collected and improve the overall function of IIoT systems, making them responsive and adaptable to changing conditions.

Understanding triggers is essential for anyone working in the domain of data acquisition, as they play a critical role in the performance and effectiveness of monitoring and analysis systems.
