BACnetConfEventNotification
(FUN)
FUNCTION BACnetConfEventNotification : IEC_BACNET_STATUS
Sends a ConfirmedEventNotification request.
Sends a request to notify a remote device that an event has occurred. A confirmation reply is expected to indicate that the notification has arrived. The event recipient could later use the Acknowledge-Alarm service to indicate that the event has been noted by an operator or supervisory program. Only one recipient can be notified by a single invocation of this service. This routine sends Confirmed-Event-Notification requests. This routine may control APDU properties like APDU length, segmentation, and timeout for both request and response. This routine can execute asynchronously, This routine will return to the caller before the BACnet reply is received so that the applications can keep running. In this case the response information will be received by the thread which is responsible for receiving asynchronous responses. An optional BACNET_SIMPLE_ACK_COMPLETE_CB() routine, which has to be provided by the BACnet application, will be used to process this information. If a number of asynchronous requests are sent, the responses will be queued and identified by the transaction handles. If the application does not supply the BACNET_SIMPLE_ACK_COMPLETE_CB() routine, then the BACnetConfEventNotification() routine sends a request and waits for reply.

Input
pSourceAddress
POINTER TO IEC_BACNET_ADDRESS
If the BACnet application has only one device constructed and installed, this can be 0. In this case the MAC address of this device will be used. Otherwise this shall be the MAC address returned on device object construction.
pDestinationAddress
POINTER TO IEC_BACNET_ADDRESS
This is the MAC address of the device to which the request should be sent.
pEventInfo
POINTER TO IEC_BACNET_EVENT_NOTIF_INFO
A pointer to the service information data structure.
pAPDUParams
POINTER TO IEC_BACNET_APDU_PROPERTIES
A pointer to the APDU-Properties structure which sets APDU properties for this transaction only. This does not change global defaults or settings for the application APDU Properties. This argument may be 0. In this case APDU properties are used which were specified in the device object properties of the applications device which sends the request.
pTransactionToken
POINTER TO BACnetAsyncTransactionToken
Transaction token of the asynchronous call - see BACnetAsyncTransactionToken.
pError
POINTER TO IEC_BACNET_ERROR
A pointer to a structure to hold BACnet Error information. pError may be 0 if the application isn’t interested in detailed error information.
