Application

The application layer is the primary interface for building BACnet clients and servers. It manages the lifecycle of transports, network layer, transaction state machine, COV subscriptions, and background engines.

• Client API – Client (convenience) and BACnetClient (protocol-level). See Client Guide for usage.

• Server API – DefaultServerHandlers and custom handler registration. See Server Mode for usage.

• Engines – EventEngine, ScheduleEngine, TrendLogEngine, AuditManager, COVManager. See Events and Alarms and Server Mode.
