According to the BACnet protocol documentation:

Defines a standardized object whose properties represent the externally visible characteristics of a named data value in a BACnet device. A BACnet device can use an Integer Value object to make any kind of signed integer data value accessible to other BACnet devices. The mechanisms by which the value is derived are not visible to the BACnet client.

Objects of type integerValue have the following properties:

•ackedTransitions
