When a scan group is configured under a DI object, what is the primary function of the ActiveAll mode?

The primary function of the ActiveAll mode in a scan group configured under a Data Interface (DI) object is to maintain an active scanning state for all attributes within that group. When ActiveAll mode is enabled, every attribute in the scan group is set to actively monitor for changes or updates, ensuring that any relevant data changes are captured and processed in real-time. This is particularly important for applications requiring consistent and timely data visibility, as it allows the system to immediately react to changes in the underlying data source.

In contrast to minimizing resources or keeping attributes non-active, the focus of ActiveAll mode is on ensuring full operational readiness for all attributes. While resource management can be a consideration in different scanning modes, the explicit purpose of ActiveAll is to guarantee that all attributes are monitored and thus are 'active', which can be crucial for applications where data integrity and update frequency are vital.
