BACnetDeleteObject (FUN) ¶ FUNCTION BACnetDeleteObject : IEC_BACNET_STATUS Sends a DeleteObject request. Sends a request to remote device to delete an existing object. This service cannot be applied to Device object. This routine may control APDU properties like APDU length, segmentation and timeout for both request and response. This routine can execute asynchronously, i.e. this routine will return to the caller before the BACnet reply comes so that the applications can keep running. In this case the response information will be received by the thread that is responsible for receiving asynchronous responses. An optional BACNET_SIMPLE_ACK_COMPLETE_CB routine, which is provided by the BACnetc application, shall be used to process this information. If a number of asynchronous requests are sent, the responses shall be queued and identified by the transaction handles. If application does not supply the BACNET_SIMPLE_ACK_COMPLETE_CB routine; then the BACnetDeleteObject routine sends a request and waits for reply. InOut: Scope Name Type Comment Return BACnetDeleteObject IEC_BACNET_STATUS A status indicating if the operation worked. 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. pObjectID POINTER TO IEC_BACNET_OBJECT_ID A pointer to the memory block to convey the Object Identifier of the Object to delete. 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.

Instructs a remote device to enable/disable initiating and responding to all APDUs (except Device-Communication-Control and Reinitialize-Device, in the IEC_BACNET_DCC_VALUE.DCC_DISABLE case). This routine may control APDU properties like APDU length, segmentation and timeout for both request and response. This routine can execute asynchronously, i.e. this routine will return to the caller before the BACnet reply comes so that the applications can keep running. In this case the response information will be received by the thread that is responsible for receiving asynchronous responses. An optional BACNET_SIMPLE_ACK_COMPLETE_CB routine, which is provided by the BACnet application, shall be used to process this information. If a number of asynchronous requests are sent, the responses shall be queued and identified by the transaction handles. If the application does not supply the BACNET_SIMPLE_ACK_COMPLETE_CB routine; then the BACnetDeviceCommControl routine sends a request and waits for reply. InOut: Scope Name Type Comment Return BACnetDeviceCommControl IEC_BACNET_STATUS A status indicating if the operation worked.

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.

BACnetGetAlarmSummary (FUN) ¶ FUNCTION BACnetGetAlarmSummary : IEC_BACNET_STATUS Send an GetAlarmSummary request This routine generates a Get Alarm Summary service request. It is used by a client BACnet user to obtain a summary of “alarm-active” objects within the given device that is capable of alarm processing. The “alarm-active” objects are objects that have any value but IEC_BACNET_EVENT_STATE.STATE_NORMAL for the Event_State property and IEC_BACNET_NOTIFY_TYPE.NOTIFY_TYPE_ALARM for the Notify_Type property. InOut: Scope Name Type Comment Return BACnetGetAlarmSummary IEC_BACNET_STATUS A status indicating if the operation worked.

Each item of datatype IEC_BACNET_ALARM_SUMMARY consists of three parameters: Object ID of the appropriate object, the Event State of this object, and Acked Transitions property values. The application may initialize the pSummaries member of the IEC_BACNET_ALARM_INFO struture with a 0 pointer and bufferCount and summaryCount with 0 too. In this case the memory for the response is allocated by the API and the application is responsible to release it with a call to BACnetFreeStackAllocatedMemory if the buffer is no longer needed. 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.

In this case APDU properties are used which were specified in the device object properties of the applications device which sends the request. pInfoBuffer POINTER TO IEC_BACNET_ENROLLMENT_INFO A pointer to a memory block into which to place summary information, which is a list of Enrollment Summary items. Each item of datatype IEC_BACNET_ENROLLMENT_SUMMARY consists of the following parameters: the Object ID of the appropriate object, its event type, event state, notification priority, and notification class property values. The application may initialize the pSummaries member of the IEC_BACNET_ENROLLMENT_INFO struture with a 0 pointer and bufferCount and summaryCount with 0 too. In this case the memory for the response is allocated by the API and the application is responsible to release it with a call to BACnetFreeStackAllocatedMemory if the buffer is no longer needed. 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.

BACnetGetEventInfo (FUN) ¶ FUNCTION BACnetGetEventInfo : IEC_BACNET_STATUS Sends a GetEventInformation request. Sends a request to obtain a summary of “event-active” objects within the given device that generates event notifications. The “event-active” objects are objects that have any value other than IEC_BACNET_EVENT_STATE.STATE_NORMAL for the Event_State property, or have an acked- transitions property that has at least one of the bits ( IEC_BACNET_EVENT_TRANSITION_BITS.EVENT_TRANSITION_TO_OFFNORMAL , IEC_BACNET_EVENT_TRANSITION_BITS.EVENT_TRANSITION_TO_FAULT , IEC_BACNET_EVENT_TRANSITION_BITS.EVENT_TRANSITION_TO_NORMAL ) set to FALSE. This routine allows to control APDU properties like APDU length, segmentation, and timeout for both requests and responses. This routine can execute asynchronously, i.e. this routine will return to the caller before the BACnet reply comes so that the application 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_EVENT_INFO_COMPLETE_CB routine, which is provided by the BACnet application, shall be used to process this information. If a number of asynchronous service requests are sent, the responses shall be queued and identified by the transaction handles. If the application does not supply the BACNET_EVENT_INFO_COMPLETE_CB routine, then this routine sends out a request and waits for a response. Asynchron call, which fills pResult with the call result in an asynchronus manner. As soon as pInfoBufferStatus is IEC_BACNET_STATUS.BACNET_STATUS_OK the data in pResult is valid. InOut: Scope Name Type Comment Return BACnetGetEventInfo IEC_BACNET_STATUS A status indicating if the operation worked. 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.

If ObjectID parameter is omitted, the returned summary shall start with the first event-active object. 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. pInfoBuffer POINTER TO IEC_BACNET_EVENT_INFO A pointer to a memory block of datatype BACNET_EVENT_INFO to place the response information. It contains a list of Event Summary items. Each item of datatype IEC_BACNET_EVENT_SUMMARY consists of a number of parameters that describe the appropriate object. ObjectID, Event-State, Acked-Transitions, Notify-Type, and Event-Enable parameters convey values of the corresponding properties of the object. Event-Stamps parameter conveys the timestamps of the last event notifications for TO-OFFNORMAL, TO-FAULT, and TONORMAL events. Event-Priorities parameter conveys the priorities specified in the Priority property of the associated notification class object. Event Info data structure contains actual number of the items returned, and the total length of Event-Summary list buffer expressed as a number of items this buffer can hold. The last parameter of IEC_BACNET_EVENT_INFO data structure is the More Events flag which indicates whether (TRUE) or not (FALSE) more objects exist that should be listed, but that cannot be conveyed by the reply because APDU is too short. The application may initialize the pSummaries member of the IEC_BACNET_EVENT_INFO struture with a 0 pointer and bufferCount and summaryCount with 0 too. In this case the memory for the response is allocated by the API and the application is responsible to release it with a call to BACnetFreeStackAllocatedMemory if the buffer is no longer needed. 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.

BACnetLifeSafetyOperation (FUN) ¶ FUNCTION BACnetLifeSafetyOperation : IEC_BACNET_STATUS Sends a LifeSafetyOperation request. Sends the requests to provide a mechanism for transporting specific instructions from an operator to silence, audible or visual notification appliances or reset notification appliances. This service may be used in fire, life safety and security systems. Because the present version of this BACnet API does not support a default processing for this service, the destination has to include a Hook procedure to process it. This routine may control APDU properties like APDU length, segmentation and timeout for both requests and responses. This routine can execute asynchronously, so this routine will return to the caller before the BACnet reply is received so that the application keeps running. In this case the response information will be received by the thread that is responsible for receiving asynchronous responses. An optional BACNET_SIMPLE_ACK_COMPLETE_CB routine, which has to be provided by the BACnet application, shall be used to process this information. If a number of asynchronous requests are sent, the responses will be queued and identified by their transaction handles. If the application does not supply the BACNET_SIMPLE_ACK_COMPLETE_CB routine, then this routine sends a request and waits for reply. return IEC_BACNET_STATUS InOut: Scope Name Type Comment Return BACnetLifeSafetyOperation IEC_BACNET_STATUS Input pSourceAddress POINTER TO IEC_BACNET_ADDRESS If the BACnet application has only one device constructed and installed, this can be NULL.
