+ * @section DESCRIPTION
+ *
+ * The GetEventInformation service is used by a client BACnet-user to obtain
+ * a summary of all "active event states". The term "active event states"
+ * refers to all event-initiating objects that have an Event_State property
+ * whose value is not equal to NORMAL, or have an Acked_Transitions property,
+ * which has at least one of the bits (TO-OFFNORMAL, TO-FAULT, TONORMAL)
+ * set to FALSE.
