Totalization Extensions track an attribute over time. There are three types of totalization extensions:
-
Analog Totalization - Tracks and records analog attribute values over time.
-
Event Totalization - Tracks the number of events/transitions of an attribute over time.
-
Runtime Totalization - Tracks the total time that an attribute resides in a specified state.
