|
* @section DESCRIPTION
|
|
*
|
|
* The GetEventInformation service ACK service handler 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.
