BACnetServer.RegisterCallback (METH)

METHOD RegisterCallback : CmpBACnet.IEC_BACNET_STATUS

Registers a FB implementing IBACnetEventConsumer (itfEvent) to a BACnet-Stack-Callback of type eCallbackType. Since a callback may have a release event, too (occuring after the returned information of the first call has been processed; at the moment only supported by BACNET_CALLBACK_READ), another FB implementing IBACnetEventConsumer (itfReleaseEvent) may be registered also. The method of the IBACnetEventConsumer interface gets called whenever the specified callback occurs after registration.

Note

For callbacks to occur for a specific BACnet-Object-Property call “SetPropertyCallbackAttachment” of the specific object in order to activate the callback for the specific BACnet-Object-Property. Without activation no callbacks will occur (assuming the predefined settings are used).
