pValues

POINTER TO IEC_BACNET_PROPERTY_STATES

This parameter is a list of BACnetPropertyStates that apply to the CHANGE_OF_STATE event algorithm. This event algorithm applies to referenced properties that have discrete or enumerated values. The List_Of_Values is a subset of the possible values that the property may have. If the value of the referenced property changes to one of the values in the List_Of_Values, then the Event_State property of the Event Enrollment object makes a transition TO-OFFNORMAL and appropriate notifications are sent.
