This OPC UA ObjectType represents an abstract type related to the BACnet Algorithmic Change Reporting mechanism. Algorithmic change reporting is a general concept that can be applied to properties of any object. The actual algorithms used to generate the events are similar to those used by EventReporting.
The subtypes of BACnetEventAlgorithmType defined in the following clauses represent the event algorithms defined in chapter 13.2 Event Algorithms in the BACnet standard.
