/** @defgroup RDMS Device and Network Management Service BIBBs
|
|
* These device management BIBBs prescribe the BACnet capabilities required
|
|
* to interoperably perform the device management functions enumerated in
|
|
* 22.2.1.5 for the BACnet devices defined therein.
|
|
*
|
|
* The network management BIBBs prescribe the BACnet capabilities required to
|
|
* interoperably perform network management functions.
|
|
*//** @defgroup DMDCC Device Management-Device Communication Control (DM-DCC)
|
|
* @ingroup RDMS
|
|
* 16.1 DeviceCommunicationControl Service <br>
|
|
* The DeviceCommunicationControl service is used by a client BACnet-user to
|
|
* instruct a remote device to stop initiating and optionally stop responding
|
|
* to all APDUs (except DeviceCommunicationControl or, if supported,
|
|
* ReinitializeDevice) on the communication network or internetwork for a
|
|
* specified duration of time. This service is primarily used by a human operator
|
|
* for diagnostic purposes. A password may be required from the client
|
|
* BACnet-user prior to executing the service. The time duration may be set to
|
|
* "indefinite," meaning communication must be re-enabled by a
|
|
* DeviceCommunicationControl or, if supported, ReinitializeDevice service,
|
|
* not by time.
|
|
*//** @defgroup NMRC Network Management-Router Configuration (NM-RC)
|
|
* @ingroup RDMS
|
|
* The A device may query and change the configuration of routers and
|
|
* half-routers.
|
|
* The B device responds to router management commands and must meet the
|
|
* requirements for BACnet Routers as stated in Clause 6.
|
|
*
|
|
* 6.4 Network Layer Protocol Messages <br>
|
|
* This subclause describes the format and purpose of the ten BACnet network
|
|
* layer protocol messages. These messages provide the basis for router
|
|
* auto-configuration, router table maintenance, and network layer congestion
|
|
* control.
