|
|
* The Who-Has service is used by a sending BACnet-user to identify the device
|
|
* object identifiers and network addresses of other BACnet devices whose local
|
|
* databases contain an object with a given Object_Name or a given Object_Identifier.
|
|
* The I-Have service is used to respond to Who-Has service requests or to
|
|
* advertise the existence of an object with a given Object_Name or
|
|
* Object_Identifier. The I-Have service request may be issued at any time and
|
|
* does not need to be preceded by the receipt of a Who-Has service request.
|
|
* The Who-Has and I-Have services are unconfirmed services.
