BACnetRetrieveObjectData (FUN) ¶ FUNCTION BACnetRetrieveObjectData : IEC_BACNET_STATUS This function retreives the requested kinds of properties for the given list of objects from the specified device instance. This procedure will read the object-list property of the given device instance if no object-list was specified by the caller. It will use up to nMaxActions concurrent requests to receive the requested data from the objects. It will use different read-access services supported by the device to read the objects properties. NOTE: This is an async function which will not block the caller during its execution. Return: IEC_BACNET_STATUS InOut: Scope Name Type Comment Return BACnetRetrieveObjectData IEC_BACNET_STATUS Input pRequest POINTER TO IEC_BACNET_OBJECT_DATA_REQUEST Pointer to information which specifies which objects from the device and which kind of properties should be retrieved to build the information requested. pICallback CmpEventMgr.ICmpEventCallback Pointer to the event-callback interface. Event-callback argument type is EVT_BACNET_OBJECT_DATA_PROGRESS . Purpose documented in BACstack: Pointer to the user application callback funktion to inform about failures and progress information along with information about retrieved object data during the procedure execution. pAPDUParams POINTER TO IEC_BACNET_APDU_PROPERTIES A pointer to the structure which contains a set of APDU properties to control the timing and size of transmitted frames for this request. It temporarily overwrites the global APDU settings made in the source device from which this request is sent and which parameters would control this request if this pointer is NULL. pTransactionToken POINTER TO BACnetAsyncTransactionToken Transaction token of the asynchronous call - see BACnetAsyncTransactionToken .

BACnetRegisterClientEventNotificationCallback (FUN) ¶ FUNCTION BACnetRegisterClientEventNotificationCallback : IEC_BACNET_STATUS Registers the user application callback for received event notifications. This function gives a user application the ability to get notified on reception of registered event notifications which have been registered by using the ::BACnetRegisterClientEventNotification function. Return: IEC_BACNET_STATUS InOut: Scope Name Type Comment Return BACnetRegisterClientEventNotificationCallback IEC_BACNET_STATUS Input hCustomer IEC_BACNET_HANDLE An handle to an created advanced BACnet client customer created by ::BACnetOpenClientCustomer. pICallback CmpEventMgr.ICmpEventCallback Pointer to the event-callback interface. Event-callback argument type is EVT_BACNET_CLIENT_EVENT . Purpose documented in BACstack: A pointer to the user application function which gets called on reception of registered events. To unregister from notifications a NULL pointer shall be used here.

BACnetRegisterClientUnsubscribeCompletionCallback (FUN) ¶ FUNCTION BACnetRegisterClientUnsubscribeCompletionCallback : IEC_BACNET_STATUS Registers the user application callback for completed unregistrations. This function gives a user application the ability to get notified if an unregistration of device object property reference has completed. Depending on the type of registration made (COV, COVP or POLLING), an unregistration may need some time to be processed. The function for initiation of the unregistration ::BACnetUnregisterClientDataPoint completes directly but the callback is called after the unsubscription for event or value notification in the remote device has completed. The application may only expect unsubscribe complete callbacks for which the ::BACnetUnregisterClientDataPoint function call has returned the BACNET_STATUS_BUSY. In case that all registered references have been retrievd by polling this function callback will also be called for the last customer which unregisters the last reference to an device but the referenced object will be the device and the property will be PROP_ALL and the index BACNET_VOID_INDEX.

BACnetDecodeAsn1StandardProperty (FUN) ¶ FUNCTION BACnetDecodeAsn1StandardProperty : IEC_BACNET_STATUS Decodes the given BACnet ASN1 encoded property data type into an property contents buffer. Decodes the given BACnet ASN1 encoded property data type into an property contents buffer. The encoded data has to match the expected encoding given by the object type and property identifier which correspond to an defined BACnet data type structure. If the encoding does not match an corresponding error will be returned. In some cases some mismatch of the ASN1 encoded data can not be detected and thus c-structures with invalid data may be created as result.
